This is the 5th tile project we've done where we've removed the old tile before installing new tile, and the first one with this tool kzhead.infoUgkxqqoaX03nrziKwF7Bjjcc71YzLEleMvOS . I want to cry for all the unnecessary work we've done in the past. With this tool, we removed tile surrounding a fireplace, as well as the hearth tile, set in loads of cement, in less than an hour. I highly recommend this tool. It was easy to use, and very satisfying watching the tile literally fall off the wall.
I will never forget my first experience of using SDS drill after breaking two standard drills trying to drill concrete. The feeling was sheer pleasure. I love my SDS drill and second everything you've said in the video. Wish I bought one years ago.
Totally agree. You can feel the engineering at work.
Well said!
I bought one and have 0 regrets. It was not even that expensive.
DIYer here. I bought an SDS because I simply wanted one. Had it for four or five years and haven't looked back.
There are a few English 'backronyms' of SDS - 'Slotted drive system' as you quote is one, another is 'Special Direct System'. The original however is German: Steck, Dreh, Sitz - Insert, Twist, Secure. This was a tagline used by Bosch in the 70's.
The German explanation makes sense, since sometimes Jigsaws with T-shank holder are also referred to as SDS tool holder
I have that drill. It's superb, remember being totally shocked when first using it,so much easier than my usual hammer drill. Building extension it was battered and abused and still works great. Broke up 4inch thick 300mm wide concrete to dig a 7m long trench. Used it to core drill a150mm hole through 700mm of concrete. Bought an angled spade chisel and taken of rooms full of plaster and tiles. If it died now, it owes me nothing and I'd replace with the same. 👍
Nice one!
Same, screwfix special. Need some wider chizels
You're lucky the core didn't snag as the drill would have snapped your wrists.
@@realtalk1590 Is that something that happens??
@@davak72 purpose built coring tools have a brake which stops them turning if they catch, otherwise the bit you're holding on to spins and so do your bones 😓
I don’t do a lot of diy so was happy with my battery drill. It wasn’t until 6 years ago when I moved and got gifted my first ever flat screen tv which needed mounted on the wall (due to energetic dogs) that I invested in an SDS. All of my small jobs are still done with the battery drill, but it’s good knowing in future I can manage the hard jobs.
Two points: Even the relatively small SDS drills are a great advantage compared to conventional masonry drills. I use one I got from ALDI for the easier jobs and Hitachi for the heavy stuff. Perhaps you should have included a reminder to grease the SDS bit so it slides freely in the drill. This end can get hot if not lubricated.
Was researching to buy a drill for home use, this is by far the best and most in-depth video I have watched on the topic. A SDS+ Rotary Hammer drill it is. Keep up the good work, Stuart.
As said, great advice. Trying to drill into very hard brick and blunting bits as a result, I was all ready to spend £200 ON THE WRONG THING until I saw your video. 24 hours later, I have the drill, I have really neat 6mm holes, with rawlplugs fitting snugly inside. Actually FWIW I don't have exactly that model. Because it was £70 rather than £90 for "your" model right now, I bought the TITAN TTB278SDS 6.3KG ELECTRIC SDS PLUS DRILL & 9 PIECE ACCESSORY KIT 230-240V. AFAICT it is exactly the same model, just with fewer bits and chisels. You saved me time and £130 - thanks a lot!
Great advice. I totally melted the end off a 12mm masonry bit just going at it hard. Only learnt later about low rpm, low pressure. This is even more relevant when drilling into concrete with rebar in it. I bought one of those Titan SDS drills, and by just setting it at low rpm and letting the weight of the drill do the pushing (I was drilling vertically downwards) the drill just chomped through the concrete and any rebar it encountered - whereas before with my normal drill and lack of knowledge I was just punishing my ears, punishing the bits, and going nowhere fast :) Great content as usual - thanks!
Thank you - good comments
This video is exactly what I needed to see, I have that dewalt and have struggled like hell to drill into the house brick work. Thank you for sharing, very useful.
I have the same model and was using it today to remove concrete from a fence post hole........goodness me I needed it and it did the job. These things are a must for home DIY etc. Great channel.
I've put off buying an SDS drill for years until a timber wooden spur had rotted at the base leaving a stub in concrete, I spent nearly the whole of yesterday pounding away at the concrete around the wooden stub using a club hammer and various chisels. Now I can't wait to use my new SDS drill to break out the concrete so I can fit a new concrete spur and bolt that through the fence post. Great video, thank you for showing this.
Thanks for another quality video Stuart. SDS is definitely the way to go if tackling heavy duty concrete drilling. So much easier and less impact I think on your arms and wrists. Just watch out with some of the cheaper SDS machines as they may not have a clutch which means if it binds and gets stuck, it will potentially spin you around and break your arm off.
Thanks for all your videos! Explains it all so well. I need to drill a run of holes in a 50 year old concrete retaining wall and had hit exactly the same issues you mentioned with a normal hammer drill, just ordered the same SDS you revewied the titan 631 set as looks exactly what I need for the job, so this video is very much appreciated. 👍
Great video, picked up exact same titan drill set last year for taking out a chimney breast. Also used it for core drilling later on for an extraction fan after my black and decker hammer drill started to smoke under the strain. Probably my favourite tool I've bought in a long time.
I got a Bosch Bulldog SDS to mount my safe to a basement floor. About 4 minutes to drill four 1/2" holes in old concrete. WHat a joy.
My first SDS experience was putting a 1/2" hole through a granite gatepost, I'd been at it for ages when my neighbour brought his SDS Plus drill round; epiphany moment. I now have a 3.5Kg SDS Plus and also a 6.5Kg SDS Max when I had to drill dozens of 500mm deep 50mm holes in a granite outcrop in the garden.
Yup to all of that! I had my first experience of an SDS drill at work about 30 years ago - what was then an eye-watering value of cordless Hilti. I couldn't possibly justify that kind of expense for myself, but I was delighted when machines like your Titan (I've got a Titan myself, very similar) started appearing for not much more than beer money. Totally worth having, even if I don't pull it out every weekend.
I just bought an SDS 1/2 in hammer drill. Thank you for your video.
This is really good advice. I tried drilling my garage brickwork three months ago to put insulation on the wall, so needed many holes to take rawleplugs and screws for the framework. The first three holes, drilled with a ‘hammer drill’ nearly killed me, never mind the drill bit! (I’m 75..). I got out my cheap SDS drill and it went through the process like a hot knife through butter, a real pleasure. Don’t mess about, get an SDS drill and do it right. Les
Quite right! Totally different experience with SDS
First time I've seen your videos. I really appreciate that you speak of the mechanics, or the engineering of how an SDS system works. This is what I've understood from your explanation: when a hammer strikes a bit of concrete, a chip flies away; an SDS is a slow, precise, controlled hammer. Bits are usually about cutting. SDS is about striking and removing dust from the hole. In short, it's a versatile baby jackhammer. Good job.
Thanks. Yes exactly
Agree 100%, brought an SDS 12 months ago when having to fix down a toilet to concrete floor. My Old man told me there was no need.......Now use regularly on my current reno project and also found great for mixing jointing compound with a mixer attachment.
Great video thanks. I struggled making an opening in a wall for a cat flap until I bought my SDS drill. Did it in a few minutes like a knife through butter. SDS drill on hammer only with a wide chisel bit very useful for removing wall tiles.
Another great video from PD. I'd add tiling to the list of items to remove. With a wide chisel they are a breeze ro remove from floors and walls.
My neighbour lent me his SDS drill when I needed to drill through brick. I was astounded how much easier it made the job when compared to previous work using a hammer drill.
I purchased an older version of that Titan drill when we did a kitchen update and remodel a number of years ago. I used it to take down a wall, remove both floor and wall tiles, drill numerous holes, chase walls and cut out recesses for new electrical back boxes and it never missed a beat. It was a bit on the heavy side but that was only a minor issue, a big mistake, which I believe a lot of people make, is applying too much pressure when working with an SDS drill, I find it more effective, especially when chiselling, to use the weight of the drill itself and apply little or no pressure at all. Oh and I still have it by the way, it may look a bit grubby now but it still works fine.
Nice one - goo point.
Thank You Stuart for pointing me in tho right direction. I have now purchased a Titan, purely for punching through an inspection chamber, using the chisel tool attachment This was the day after trying to break through with a angle grinder with a steel cutting blade. An investment i feel has been well spent and will see me through for many years. cheers Stuart.
Concisely and precisely explained everything that is not known to us mere mortals in terms of terminology and usage from the manufacturers themselves. Thank you. Regards from Serbia.
Picked up the same model of Titan drill on market place for £20. Used once and in as new condition. Awesome bit of kit 👌
great video, really saved my bacon taking out an old concrete fireplace when i was renovating my house , keep up the good work !
I just bought this exact SDS drill, and like magic, this video pops up in my feed. Great video, well explained. You've got a new sub my friend!
I work as an installer who often drills into concrete and porcelain tile. I just broke my third drill in one year, and glad I decided to do some research instead of just buying another one.
Thanks so much …. Great information (as ever) and revelatory to me in terms of the breaker function particularly …. Why have I not paid such relatively low money before for what you’ve just explained 👊🏼
Great video. I've always passed by these tools in the hardware store wondering what their use case were. Now that I own a house made of brick and block I can see myself needing something like this.
Glad I could help!
Fantastic video like always, I honestly look forward to you releasing a new video. Keep up the fantastic work Stuart 👍👌
I had the same issue when trying to feed out poe network cables for cctv. My standard drill totally failed to go through and I ended up paying someone who had an sds drill with drill bit long enough to go through external wall. You channel is top.
I have that Titan and it helped me take up an old, thin concrete path at the side of the house for the builders to put down a block paving pathway. Saved me a pretty penny.
really great info and brilliant to understand the science behind these. I have both but did not realise the actual differences in how they work. - Thanks, Ben.
No problem
Was going to say the same, just knowing how they operate differently makes so much sense , downside ,I need to check my drill bits as I reckon 75% will be blunt...screw fix here I come 😬
Great explanation of drills. You have made me want to go purchase one for going through harder substances.
Thank you for taking the time to break this all down! This could’ve saved me a lot of headache with hanging items from our concrete basement walls.
You are so welcome!
Thank you, this is exactly the information I needed. I got offered a bargain on one of these but couldn’t think why I would need one… Now I’m thinking about all the holes I will need to put in concrete block walls, concrete laid where I want to put a deck , busting through rock when putting in fence posts and even the more heavy duty drilling in softer materials. Off to accept the offer now!
Whilst I know all about hammer & SDS drills (I have both), I still watched to the end! Must be something about your presentation style (which I clearly like) that make them compelling to watch. Anyway, well done, keep them coming.
Glad you enjoyed it!
Brilliant. A fantastic tutorial. I have the exact same Titan model and it's got me out of the brown stuff many times - including concrete lintels (our house is 70 years old). The best, I had a fence post snap during a storm. The Titan smashed up the concrete base like a hot knife through butter in 15 minutes. Postcrete, new post, very happy neighbour (they had a dog) and done in an couple of hours. Considering what it is - about £80, with all the bits too, an absolute steal. Very rugged, plenty of grunt, and puts a few brands to shame.
Good to see I'm not the only one!
I purchased an SDS about 15 years ago. Didn't need it at the time. I tend to see a bargain tool, buy it thinking eventually I'll find a use for it. Fast forward about 5 years. I tried smashing up a old concrete garden path with a sledge hammer. Nigh on impossible. Then ding 💡let's try the SDS out. That's when I realised everyone needs an SDS drill in their kit. Turned off the drill function, put the spike in the chuck and bang. About 45 minutes later I had a path of hard core. Couldn't believe how easy it was. Now never with out an SDS drill. In fact I now have two. Great demo vid Stuart 👌
Nice one! Good example - I wish I had seen my video 15 years ago!
That’s exactly why I’m here watching this video - saw a bargain on one of these and need to know the reasons why I should own one 😆
I actually thought i was the problem before buying and SDS Plus, i couldn´t drill into my ceiling with a standard hammer drill. For concrete works its a must.
Honestly, it's probably because I'm in my 30's, but i find learning about tools/house maintenance extremely interesting and useful. We bought a fixer-upper in '21 and it took 18 months of sub-floor replacement, chasing out wires, drilling in joists using a paddle bit to run wires etc but by the end, i went from absolute novice to relatively adept at tools thanks to videos like this. Sds/drill-driver/combi drill / impact driver et all can all seem like technical terms and a bit intimidating, but learning about different drills and their application is interesting and useful. Thanks for all you do. It's always funny when the handrill can't even dent our 45yo concrete posts, i feel the post laughing at me. Then the plug-in SDS comes out, and the post hears boss music 😂
A bout of “tennis elbow” and ruined drill got me into SDS!
I learn so much from you, thank you for the awesome channel! My concrete wall has a lot of pebbles that are really hard. I need an SDS drill for sure.
Something I never knew as a DIY'er . Thank you fella
My Bosch 24v sds drill just died after many years of use,so just treated myself to a new Bosch GBH 18V-26 sds drill, rather impressed with, it drilled 25mm diameter holes with ease for fittting some weep vents.Can also recommend the Heller SDS-Plus"Trijet" bits, they go through the hardest concrete/brick with ease.
Another very informative and helpful video thanks. I came to the conclusion that it is high time I invested in an SDS drill. The Titan looks robust and good value and I'm looking forward to finally being able to drill into concrete without all the problems you outlined at the start of your video! Thanks for the advice.
Thanks for this vid. I didn't know what drill to use or what the difference was. Some awesome tips I won't forget. Clearly explained, winner winner 🏆
Everyday is a school day, very hard to find good video's that explain as detailed as yourself. Love the channel, keep them coming.
Well thank you very much
I agree wholeheartedly with your comments on an SDS drill. I also regret I did not buy one sooner.
Nicely explained! It is a good idea to lightly grease the hammer groove part of the bit due to friction.
I purchased this Titan SDS drill several months ago and I can agree with Stuart, it’s a great drill! Absolute bargain for under £80. I recently bought a tile chisel and it removed bathroom tiles with ease! An absolute beast of a machine, when you need to bring out the big guns - this drill won’t let you down 👌🏻
Well said!
I've used a smaller DeWalt SDS drill with a spade fitting to remove tiles. I can confirm that a good SDS drill with spade fitting easily gets tiles off walls, and quickly.
When I bought my SDS it was a revelation. Its the biggest 'unknown' tool in my experience. Every diyer should have one
I was sold on SDS after one of the Sparkys at work lent me one to install some expansion bolts. His instruction was 'don't lean on it, let it do the job. You can use it one handed'. I've got a couple now; a cheepo Screwfix one (like in the video) and a 2kg Makita one. The Makita is the every day use machine (it's an LXT battery model) as the smaller size is more appropriate for those indoor jobs but the big machine is there for the large holes and the breaker jobs. It doesn't come out often but at £50 it's not something I mind keeping on the shelf (expensive tools that I've bought for big projects get a couple of years grace once the project is over and, if not used, get sold on as space is always at a premium. Sometimes the policy pays off. I bought a Belle minimix concrete mixer, used it almost daily over a couple of years, cleaned it thoroughly after every use, held on to it for a further two years then sold it. Inflation meant that the second hand sellng price was within a few pounds of what I originally bought the mixer for new.)
Agree completely. Didn't know these existed until I needed to drill 20 5/8" holes in concrete. Makita SDS drill did it in 30 seconds. Heavy duty Makita cordless "hammer" drill couldn't do it in 5 minutes!
Exactly
what model Cordless you used?
@@UncleIvan1 The Makita Hammer-Driver CORDLESS is the XPH07 with a 5/8" carbide masonry bit. It stalled out after about 3" and 5 minutes likely because we dulled the carbide. The CORDED Makita Rotary-Hammer SDS-Plus is the HR2641. We ended up with a Bosch SDS-Plus 5/8" x 8" Bulldog Tough (Extreme) 4-cutter bit. It is still usable after 30+ 6" deep holes in concrete.
@@engineerncook6138 i have the newest version XPH14 , but I haven't tried using it on concrete. From what I've seen on other people's reviews, it's not really good for concrete . I have a Cordless sds 1" makita for the concrete
Same as you. I'm thinking I don't need one until I bought a cheap then, OH MY GOD, can't live without it now. Thanks for the guide.
Wow, you really helped me understand why I'm unable to use my drill in my new (old) apartment! Especially around the window frames. Guess it's time to buy a new drill...
Tip - the movement space that you showed us, that forward and backward sliding action of the drill bit. You can use that as a visual guide to when you're hitting steel, stop drilling. Once the drill bit stops moving forward, and is pushed back against the chuck, you've hit something very hard like steel. If you keep going you might blunt the drill bit in a few seconds. HTH.
This just what I needed! Have used a hammer drill for years but since moving cannot for the life of me drill into the solid red brick. All the advice I'd been given was simply that I needed a hammer drill (usually followed with a shrug) Now to decide on which sds drill to invest in! ...and decide where all the shelves are going!
I bought one many years ago for one job - to chip out mortar for a plumbing install. Doing the job myself saved around $100 on that the plumber would have charged me, so the tool effectively cost me around -20 dollars. Around thirty jobs later I trashed it breaking limestone rock, went and got another one the next day! A great value-for-money tool
A workmate who shall remain nameless kept moaning that the hilti drills and SDS bits were crap. We were drilling into Staffordshire Blue Bricks under a bridge fitting pigeon nets. Turns out he was drilling in reverse! 😂😂😂
🤣🤣🤣🤣🤣
Ah, that's the issue right there. If the drill is in reverse you need to start on the other side of the brick... 😂😂
@@jp6975 😂😂😂😂
Reverse really doesn't work so well
Just bought the same model drill. I've got an old concrete and brick bunker in the back yard, that needs some 'persuasion' to be demolished. Only taken me 20 years to get round to it! Hope this is a good tool. I'll be using it in the morning. God bless my neighbours!
I got such a drill for some plaster removal and anchoring a new ceiling, and immediately regretted not having gotten it sooner. It would've saved me so much time. I don't have too much use for it nowadays, but I like having it just in case.
I have a Titan, and it's a fantastic bit of kit . Especially for £50 ! Had mine for about 9 years and it's never let me down.
I have a Bosch 800W hammer drill. When you need a 25mm hole through 40cm thick brick wall, a hammer drill is a must.
Completely agree about once you have it, you'll use it. I bought one second hand from a builder who had 3 and didn't know it. Paid £40 for it and it was barely out of the box. It was the corded Bosch hammer which is not too bulky but has enough power for the jobs I need (mainly drilling brick).
Sounds like a good deal
Watching you use a hammer on the drill bit reminded me of the palaver needed to punch a hole for the old rawlplug fibre wall plugs. Progress is a beautiful thing!
I identify exactly with your thoughts about a rotary hammer drill; when I finally bought one I wondered why it had taken me so long!
Absolutely essential bits of kit. I've had a Titan for maybe 2 years now, but I'm really getting the urge to get a lightweight cordless Dewalt one as a happy medium.
Thats natural - once you know it's useful, you look to go to the next level. I'm in the same position.
I have Aldi Workzone SDS, think it was 40 pounds, very similar to the titan. Has been one my best tool purchases, would recommend to anyone who’s handy round the house. Good example of this tool shining is when you’re up a ladder drilling into brick, you would think holding big heavy sds drill would be really hard work, but turns out it takes seconds to drill a hole into that brick where using a combi drill is much harder, near impossible in fact.
Couldn't agree more
Superb video, i had the exact same curtain situation was driving me mad took be a fair bit of looking through KZhead to realise i needed an SDS.
Thank you so much for this excellent video. I recently bought an erbauher SDS still and almost instantly regretted it when I saw a DeWalt hammer drill on sale a week later. This has justified my purchase and made me feel so much better about my choice.
Glad it was helpful!
used a cheapy b&q sds drill to drill into old ww2 aircraft hanger floors to bolt racking down. sailed through that 60+ years old concrete that was V V hard. brilliant bit of kit. Hilti drill bits are brilliant as well, worth the money as the ones supplied in the case are usually carp!
I wish I knew this in my younger years but I will still purchase one.
Love my SDS, have an SDS, 18v combi, 18v impact and a 12v combi which has it's place in tight spaces or where weight is an issue. Right tool for the right job, does get expensive but if you are a home owner they are good investments for the future.
More great advice ...and very interesting to watch plus the odd comedy which is priceless ...please dont stop making these videos ..fabulous
Thank you
Really informed video! Drilling above the window and melting the bit is precisely what happened to me! I'd like to point out to fellow DIYers that SDS drills do come in smaller sizes than that Titan shown in the video!
Thank you
So I am going to be going to pick up this tomorrow. Is it capable of breaking up parts of kerb edging foundation to fit fence posts in. Thanks
Totally agree. Bought a wired Bosch SDS with a bit set from Aldi years ago and it’s a dream. The hammer only chisel is great and saved hours on jobs. I also bought a normal chuck converter head and used it to screw decking frame no problem whilst impact drill batteries failed
Nice one!
i got the parkside version and its great!. i have put a few tv brakets up with it and it went through brick like butter, nice and straight too!!
Great explanation of types of concrete and what the alternatives are to complete a job...as for me I will use this as my guide to get the drilling done in my basement concrete wall as I have 18 holes to do and my Mikita hammer drill just wasn't cutting it. (or should I say drilling it?) Thanks this helps
Good video. I have the same Titan drill. It’s a great drill. I’ve put 150mm deep 22mm wide holes in solid concrete factory floors with it. It’s a heavy bugger but it means you don’t have to lean on it too much. It’s my go to drill for floor fixings.👍
Thanks
Thank you for making this video, that was really useful for me. It’s this kind of specific information you don’t generally find but is extremely useful to know! Subscribed :)
No problem
I love your sense of humour not only giving us a great info.
I glad you are enjoying them
Great Video Stuart, I invested in a Dewalt 18 V SDS last year and as you say I'm amazed at how many jobs I have completed that otherwise would have needed outside help. Really worth the money.
They are very versatile especially at height cause you don’t have to worry about cables but I just have a corded hikoki sds which does the job for me :)
Nice tool!
Thanks great video. Is it generally ok to drill a concrete lintel to put up a curtain pole ? Using small wall plugs , red ?
Always wondered why my drill bits gave up the ghost so quickly, now I know! as I usually applied more force thinking that was the solution, so, thanks for this informative video,
Hello Stuart - fantastic video - I am doing some DIY at the moment since I bought my Black and Decker 18v Cordless Hammer drill.and honestly, I just am obsessed with DIY now. However I had to refer to your video as I am trying to put up a small shelf in my kitchen which has 'tough' concrete walls and thought my B&D would suffice - needless to say it hasn't so 'no shelf up yet' 🤦🏽♀. So it looks like I will have to buy another drill, but the one in this video is way too big for me and for the projects I want to do around the home. Therefore could you advise what drill I should buy albeit a little smaller but effective for drilling concrete etc? Is it an SDS drill I need to purchase? Thank you for your help! Psyche aka Psyche Thompson UK 🌹p.s. I've definitely subscribed to your channel - it's marvellous. p.s. Opps I've just seen your recommendations in your description but it would still be good to hear your opinion.
Well ya learn something new every day! Informative and fun makes it a joy to watch. Another tool for the list of needs as I've only just been through 3 drill bits fitting a light 🤦♂️ following your previous guidance.
Put it on your 'Need to buy one' list
@@ProperDIY on it 😁
@@ProperDIY Trust all is well ❤️
Funnily enough, I ended up buying a Titan SDS drill in order to install the exterior power socket in another of your videos. It's a heavy brute but it certainly did the job. It's good to have it in the armoury even if it only gets used occasionally.
Nice one!
My wife been telling me that I suck at drilling. Took me 2 hours to drill 5 holes for my gate brackets. I showed her your video. Male ego restored, thank you!
Thx 4 intro vdo on SDS hammer drill.. Yes, my hammer drill has been spinning & not going deeper, most likely I've dulled my drill bit. So not time 2 invest into a SDS hammer drill. Wish I would have found yur channel earlier. Thx 4 sharing on Utube.
Great video, I have a Bosch SDS that I agree has been a gamer-changer. In you ‘sound effect’ bit, is everything alright with your double-glazing? Looked to be steamed up? Another video coming on replacing failed panels? 😀
My introduction to SDS drills was a Bosch GBH 18V-21 that came with a five piece Bosch Blue kit. It was a whole other level of drilling hard masonry, and nothing has come close to slowing it down. I have to wonder if Bosch had a sense of humour when giving the GBH prefix, because Brits will recognise it as standing for Grievous Bodily Harm. An offence just short of murder. Then again we are talking about Germans with Bosch, so humour probably didn't come into it. I've added to that five piece kit and now have about ten Bosch Blue tools. I'm glad I kept all my Bosch Green kit though, because the GDX 18V-200 driver tears off the head of anything smaller than a #10 screw, and even that is touch and go. It's better for removing vehicle lug nuts.
Nice one - good info
I had a garage floor to break up. Sledge hammer was a laborious effort. I rented one of these. Went through 5" of concrete like it wasn't even there. Couldn't believe it.
