Drill Masonry with an Impact Driver - Hex Shank Multi Material Drill Bits

In this video I review some DeWalt Multi Material hex shank drill bits I bought from screw fix. They can be used with an impact driver.

[@gunhann]

Some people are really dull saying oh buy hammer drill bla bla. If you only need to drill couple of holes into the concrete and you only have an impact driver, why would you buy a second device? I think for a DIYer or a house owner who only needs to use it less frequently impact is the best all rounder, and it is smaller. Obviously if this is your profession, you'd already have all of the different types of drivers/drills.

[@maskenmakkan]

@@The.Toaster Wrong, the impact driver has much more torque and is a great all-rounder. You can even buy adjustable chucks to put in the impact driver. Impact driver is not used for nuts and bolts, that is called an impact WRENCH. Get your facts straight buddy.

[@maskenmakkan]

@@The.Toaster Lmao, if you work with repairing rc vehicles you need to shut it, as i said the impact is great for diyer and has multiple uses, yes it uses a hex shank and there is a lot of different attachments to it. Hole-saw hex, drill hex, nut hex etc. A combi drill will never get the same torque nor speed. Dont talk about things you dont know buddy, I work in mechanical engineering so dont fool yourself. LOL.

[@enmodo]

@@maskenmakkan I completely agree. I used a regular drill / driver for years and finally broken down and got an impact driver. It's like night and day for driving screws - days of stripped heads and sheared screws are all behind me as it drives 3 or 4 inch screws through wood like butter. But I've also had a lot of luck using it with an adapter to utilize my regular sockets.

[@CB-np2ru]

Impact function isn’t in play much at all. Functioning like a regular drill. Will work fine on softer masonry but will burn up the bits due to friction on harder masonry. Hammer drill chips away as it drills and the heat is much less. Thanks for the demonstration.

[@AnunnakiAaron]

its because impact drivers apply their "impact" rotationally, not back and forth like a hammer drill. Hammer drills plunge in and out, which is really how masonry bits are designed to work. Just rotating a masonry bit is going to dull it. Masonry bits will work with the impact driver, for a little while, but it wont be long before its dull.

[@dxdux]

Please can you recommend a good set of masonry bits for a impact driver with hammer function (cordless 20v)? thanks in advance (ah, not SDS please)

[@WheresMyPencilUK]

Do you mean hammer drill? No such thing as impact driver with hammer function.

[@dxdux]

@@WheresMyPencilUK Yes. i meant a hammer drill (nowadays if you search on amazon the description will quite often be impact driver and hammer or something alone those lines)

[@WheresMyPencilUK]

Ok I find the DeWalt extreme masonry bits very good. The do them in non SDS in a set. 👍🏼

[@dxdux]

@@WheresMyPencilUK Thanks so much! ( DW5207 right?)

[@NikhilMandrekar]

Spending my Friday afternoon watching this guy drill holes in different materials..

[@WheresMyPencilUK]

Spending my Saturday evening reading comments about it.....

[@daigoldsack1254]

That dewalt impact your using is simply brilliant mates had his 6 years works perfectly

[@BUDAGX]

These multi-material drill bits are great, I used some from bosch (with a blue coat) to install some locks on ATM's vault, some model have 3 layers, steel-concrete-steel so these bits worked amazing to get through that concrete layer

[@jackjohnson9989]

Really appreciate this post. Never heard of these bits. These tool combinations have application specific uses but the laws of physics and mechanics still cannot be defied. Least not by mortals. I'd enjoy having these bits, the screwdrivers and a nice impact on a cable/conduit run where there's fastening to timber and concrete on the same run. Yet ever so often, part-way into a block there is a vein of something (flint, granite? Of course you'd know if it was rebar) that just ignores this type of drilling and bits. After some choice language one would have to climb down for the trusted old corded hammer and have it pulverize the dickens out of that tough spot!

[@Scotto6977]

Good demo,especially with most combo drill kits offering a impact and driver with no hammer

[@surecom12]

This video answers my question for concrete. Thanks.

[@scott1brayden2]

If you have a hammer drill, then just use it, yeah an impact will eventually go through brick etc, spinning without the hammer function just ruins the bit, and take so much longer.

[@Scotto6977]

Thanks for pointing out the obvious

[@x13oidragon]

Impact DRIVERS are specialized for driving in screws and bolts. Hammer DRILLS are used for drilling and minor screw and bolt driving.

[@WheresMyPencilUK]

Thanks for that Jim.

[@noelhampson4061]

Cheers just saved me buying a drill driver 👍

[@davelowe1977]

I can vouch for the Bosch bits. They will drill through anything. I've made holes in wood, cast iron and stone with no problems.

[@WheresMyPencilUK]

Thanks David I hear they are good but quite pricey.

[@davelowe1977]

Happy Wife Happy Life Depends what you mean by pricey! £3 for a 6mm from screwfix.

[@WheresMyPencilUK]

The DeWalt ones are £5 for 4. Also thats not £3 for a Bosch 1/4" hex bit so you aren't comparing the same thing as you couldn't use them in an impact driver. The 1/4" hex are £17.50 for 5 so quite a difference.

[@theartistformallyknownasdi5338]

I've used both and find the Bosch to be better, the Dewalt are good in masonry but going through timber to masonry they struggled with the timber and burned though.

[@mohsinrasul8450]

I think the third picture was for breeze blocks... Not concrete

[@madcowusa4277]

Stop immediately if you smell any burning as the motor is about to go out. Have burnt up several dewalts when using large hole saws, which admittedly is too much for it.

[@Mobile-pd1uc]

Have you also tried these on a regular cordless drill as opposed to impact driver

[@kornelijekovac9793]

So, does the ordinary accu drill go faster through the wood or concrete, compared to accu impact driver? What's the benefit of the drill over the impact driver when you compare them in drilling mode? Not talking about driving screws, that's obvious.

[@johnw2758]

Interesting but, personally, would only use them for the occasional drill into concrete but would deffo use them more for wood and plastic.

[@badger0888]

Thanks for this. Hard to beat beat a Hammer drill but this bit kit can get you out of a bind.

[@WheresMyPencilUK]

You’re welcome I actually use them quite a lot.

[@jason4547]

You sir are going to make some man very happy one of these days.

[@jondoyle44]

Good video, Playback x 2 works well

[@chancesforchancers1797]

So do we need anything other than an impact driver for all jobs!! If your a home diy’er these hex would be great for your impact. I’ve got 3 different dewalt drills I already have a custom chuck from an old dewalt drill converted into hex any chuck can be customised!! Now I feel I should get rid of all my drills and buff my brushless impact driver with hex bits for all jobs if your doing jobs at home this would be perfect but bigger jobs would need bigger tools?? I will think about what I want to do great video cheers ❤

[@WheresMyPencilUK]

I think they key things you need as a DIYer are an impact driver and an SDS drill. The impact is fine for most things but for tough masonry and concrete you will burn out this type of bit if you aren’t careful. It will get you out of a bind though.

[@axiosw0774]

​@WheresMyPencilUK If you are drilling into a wall/concrete/brick every once in a while for putting a hanger or something And you mostly fasten screws into furniture/ikea stuff I guess impact would be best, yes the bit will go bad, and the impacts life might take a hit, but this way you get a tool that is the same as hammerhead drill, while being lighter and more compact no? I'm just trying to make a sense of all of these different types of drills, I need a 20v either milwaukee or bosch - either thinking to buy 1 tool to do it all like the one with hammerhead function (jack of trades) or just an impact and a separate drill (without hammerhead function) and relying on bits for masonry stuff every now and then

[@WheresMyPencilUK]

An impact drill will not give the same function as a hammer drill as the impact is in a twisting action in the direction of rotation not a forwards impact. Therefore an impact driver will only give the same level of drilling capability as a non hammer drill. They are better for installing fasteners though due to greater torque. As I’ve said if it were me I’d get an impact and an SDS drill.

[@beerme27]

will a straight shank work with a hex shank? i have a 3/8 installer/bell hanger. i'm trying to find an adaptor for it or if i need a specific type of drill for it. my impact driver has a hex chuck that is 1/4.

[@seb.]

Because the packaging says 'impact' doesn't mean it's for impact driver, it most likely means it supports impacts from a drill (hammer drill, which can also have hex adapter and those bits gets more convenient when you do need to switch often with a single device between drilling and driving screws)

[@WheresMyPencilUK]

Not what this says. www.screwfix.com/p/dewalt-hex-shank-multi-material-impact-driver-drill-bits-set-5-pieces/4435P?tc=FA2&ds_kid=92700022882458891&ds_rl=1241687&ds_rl=1245250&ds_rl=1244066&ds_rl=1249796&ds_rl=1245250&ds_rl=1249481&gclid=CjwKCAjwsfreBRB9EiwAikSUHd-0an5qCaGYWUAg9LNqCc5pAEVYDhnY6OKDOmlMhCkBBlE6c5MUARoCWxcQAvD_BwE&gclsrc=aw.ds

[@logtec1977]

sebxx It seems like in the end, the impact driver will drill “smaller” holes in concrete/etc, in a pinch but it’s prob best to use a hammer drill. Thanks for making this video!

[@normanboyes4983]

Hi I discovered the merits of the Dewalt drill bits recently - just loved how they drilled into house brick like it was cheese. I am only an amateur and only recently discovered 'concrete' screws at Screwfix - have you tried them absolutely brilliant great time saver too?

[@WheresMyPencilUK]

Thanks Norman they are great bits. I use concrete screws. Give "wall dogs" a try they don't need plugs just a 3.5/4mm hole in the brick/mortar.

[@normanboyes4983]

Happy Wife Happy Life - Thanks for the wall dogs tip - I looked at them but they are quite limited (max length 32 mm) I recently used some 80mm jobs from Screwfix with T30 heads - absolutely fantastic.

[@shakirahmedtth]

Was looking to drill for basement concrete floor for framing..now I can buy only impact driver

Thanks Martin for £5 I think they are good value.

[@Badgerworkshop]

They look good. Next time i do an order i will get some.

[@WheresMyPencilUK]

Definitely worth it for the price!

[@ksp1278]

good review. surprised it struggled with wood. Maybe you dulled the 8mm by drilling the concrete for too long and made the bit get too hot? Anyhow, I haven't tried these. I have the bosch ones and they seemed to work ok. I like the fact they allow you to drill into brick without needing a hammer drill, so it's much quieter.

[@WheresMyPencilUK]

Thanks ksp1278 I tried them all on wood and they were ok but seemed better on brick and mortar. Made mincemeat out of breeze block and plasterboard. 6mm tends to be my go to bit size for plugs and it worked great so I might see if I can get individual 6mm bits.

[@6lr6ak6]

ksp1278 no he hasn't dulled the tip of the bit, it's tungsten carbide you thick plank.

[@regularguysgarage3276]

regardless of material it's also blunt as hell when compared to a standard HSS wood/metal bit.

[@regularguysgarage3276]

Thanks for the review was just looking at them online didn't realise they were so long.I'd snap them in 5 seconds.

[@WheresMyPencilUK]

Yes they are quite long the 4mm one is quite bendy!

[@angelacruz71]

Ive been trying to figure out how others are able to drill into concrete with an impact. I must be doing something wrong. Think i spent 5 mins trying with new bits and my makita. Lol i totally gave up and went and bought a hammerdrill. Did it in seconds.

[@WheresMyPencilUK]

Not really the ideal tool. These bits are designed to get you out of a pinch. Cheap SDS hammer drill always your best bet if doing it infrequently. Get one with rotation stop so you can use for light chiselling too.

[@TAGSlays]

Wow, big mistake in this video is not periodically lifting the driver to clear the hole of debris. This simple move make s the drilling much more efficient than just jamming your way through.

[@zedman442]

I guess the only thing going for it is that impact drivers spin at a higher speed than normal drill drivers. Flat bits work great with impact drivers.

[@WheresMyPencilUK]

Zed Man they do but you have to be careful they don’t bind. I’ve snapped a spade bit with an impact driver.

[@harryrock169]

Good video. Like it. I’ve came to see if I was drilling correctly as I was struggling with my ‘so called top of the range powerful DeWALT DCD996 Combi drill and even setting at hammer drill I struggled to make a dent on a stone built wall. Maybe i was using cheap Black & Decker drill bits. I will order some expensive ones and see if it works. I understand Combi drills mainly works well on wood etc.. but they also advertise it can be used on hard walls too such to drill on a partition wall to hung a pic for example.

[@WheresMyPencilUK]

Thanks I have this, the same combi as you and 2 SDS hammer drills (one battery one corded). If I’m drilling in masonry and especially in concrete I use the SDS. I think I’ve only used the Combi once for masonry. These impact bits are just to get you out of a pinch really. I’d recommend a cheap SDS to anyone as the chisel function is very handy. Hope that helps.

[@ninasaunders5106]

Hi! So glad I found this video. Which dewalt impact driver were you using? I have a ryobi and would love if i could use these :)

[@WheresMyPencilUK]

I’m using the DeWalt brushless 18v. Will work fine with a Ryobi as all are hex shank.

[@ginaestes8941]

[@RapapanyFiandraza]

Is it the real Dewalt or Fake?

[@petergallagher9552]

Great to see wonder would this work on a green Bosch impact driver 130 Newton meters

[@WheresMyPencilUK]

Don’t see why not!

[@rebirthtobi]

What chuck adapter are you using?

[@Blgtn43]

Thanks.

[@Mobile-pd1uc]

If you were drilling wood onto brick can you just put the plugs into the wood with a hammer and then let the screws drive the plug into the brick or is that a bad idea.

[@callumsparks]

I put the plug in the wood put the screw in alittle then hammer it so it pushes the plug through into the wall works great 👍

[@smartorder4997]

If you do that long enough you will overheat the drill bit and it will actually break.

[@romanengelbrecht6717]

awesome video thanx info was very useful

[@adrinathegreat3095]

Most people just use what's at hand, an old Steele drill bit will go through wood or brick, you don't need hammer action for that. Most people only ever drill a few holes in thing's, they aren't doing it for a job so if it takes 5minutes to drill a hole then that's ok for them. All my equipment is aeg, I've got drills impact drivers, sds drills. I have 100 of drill bits of all shapes and sizes and flat drill bits for cutting holes in wood etc etc. Most of which is never used, because I normally go overboard when I need something or think I'll need it

[@Fredengle]

got a question for you it I have an impact rated drilll for my driver is it possible to use a regular hex shaped extender or does it need to be impact rated ? I mean if the part fits should it be ok with a standard hex extension plug as long as my drill tip is impact rated? thoughts please thank you

[@WheresMyPencilUK]

I would use an impact rated extender. The torque could shatter the non impact rated one.

[@BestUserNameUK]

An impact driver does not work like a hammer drill. The impact is sideways - lateral, not horizontal.

[@WheresMyPencilUK]

Well observed. At no point did I say it did.....

[@craigh9112]

And that is why these bits have been designed for an impact driver as they drill without the use of a hammer action ! I have these and they are a good set to get you out the shit at times they are like a back up set to do the odd few holes when you don’t have your sds at hand

[@popt24]

Hi Jim watched your video liked it , I want to build a side shed and would like to drill some holes through the brick and then the rest through 70mm of wood would this be a perfect buy?

[@WheresMyPencilUK]

Yes should work well for that.

[@TomRothwell]

[@lucychillery-watson7861]

[@henrikgustav2294]

Cannot find dewalt bits here. Can i use makita ones? As long as the size is the same? 1/4” hex

[@samh3157]

Yes

[@Zoroaster4]

As long as they're masonry bits you should be fine. I've used regular drill bits before but expect them to be pretty much unusable after every hole.

[@GeorgeXCIX]

Moral of the story, impact can do it all until it faces the tough masonry, then you need the SDS.

[@markharris5771]

They are a decent price, but isn’t one of the selling points of impact drivers that you don’t need to keep changing bits in your drill? I'm not sure many people would have an impact driver but no hammer drill.

[@WheresMyPencilUK]

Maybe but I guess if up a ladder it easier to quickly change a bit than get another tool.

[@09keguti]

I only have a impact driver because I rarely drill holes. And in rare situation where I need to drill a hole these drill bits are life savers

Wouldn’t really be any comparison but these are handy if just doing a couple of holes into softer masonry or plastic.

[@db.1881]

Happy Wife Happy Life Yes but i mean that if someone want some a little bit universal tool that can do like 70 percent of every thing, 1 drill, 2 drive, 3 wrench... so if you can do some direct comparison in drilling with the Hammerdrill cordles than we will know how far the effect is.. and itu would be great if you can do open bolt test with and impact drive vs again with hammerdrill cordless, and do some driving screw.. again vs hammerdrill... i think it would be a great eye opener :) and what i meant with impact drill is a hammerdrill sorry for that

[@db.1881]

[@zack6892]

These bits make no sense when drilling concrete the impact is the most important part. What a hammer drill or preferably a rotary hammer does is makes the bit impact the surface causing a chip then the drill head digs into that chip. What your impact is doing is not the same the impact is entirely rotational you would probably get through faster with a titanium bit with a pilot head. All this bit will do is lead to premature failure of your impact driver I suggest you invest in a rotary hammer if you look to drill concrete even hammer drills aren't very effective at impacting they just use ratchet drives to create vibration more so then actual hammering.

[@zack6892]

I understand the appeal of an on hand solution for concrete drilling that saves you from switching tools but sustained high rpm with heavy drag mixed with concrete sediment will just lead to burning up your drill and of course manufactures will say it's fine they are the ones who get to sell you the replacement. You would be better served running Bosch diamond speed bits they will eat through small jobs like this and actually self feed not put all the stress on your brushless motor.

[@JAKOB1977]

great video +1 and yeah you can, of course, you an impact driver as a drill into hard stone material, at least to some extent,. and you around the same level as a combi drill hence hammer-effect or vibrato effect. and SDS rotary drill takes it quite a step further.

[@marcnaidu5804]

Nice video thanks. Goes to show that the average DIYer can get away with just having an impact driver ... if they really had to choose and could only get one power tool ... forget the expensive hammer Combi drill, the rotary drill ... just get an impact driver. It really can do it all. 👍🏻

[@carlosbah4623]

That's the point!

[@markharris5771]

Marc Naidu I’m not sure I’d try to use a forstner bit or drill metal with an impact driver, the motor was starting to over heat just drilling concrete.

[@tyler4164]

Most people who dabble with diy are more likely to have a drill not an impact driver so abit pointless. Impact drivers are not for drilling

[@0hypnotoad0]

Oh man, this is the type of drill bit you use when your time is worth less than your money, spare yourself and just buy a friggin hammer drill. This bit is demonstrably very slow, and will wear down with heat and friction because of the very high RPM that an impact driver produces. If you absolutely must drill one single very important hole in the span of your entire life, then *maybe* this bit would be worthwhile, assuming you'd never use it again. If you're a DIYer, honestly get a hammer drill before you get an impact driver. It will do all the things an impact driver does, plus actually being able to drill holes into masonry in decent time.
