- In this video I test out the HMT versa drive step drill. HMT (hole maker technologies) have a huge selection of problem-solving drill bits, taps and reamers for making metalworking much easier and faster- holemaker-technology.com/
The impact rated step drill in this video is a superb piece of kit, which can effortlessly make holes in steel very quickly. - แนวปฏิบัติและการใช้ชีวิต

HMT sent me this step drill to test out, plus a few other bits which will be tested in future. I used this yesterday to make four 12mm holes in some Unistrut in a matter of seconds using my impact driver (not impact wrench, as in this video). These make drilling thin metal a real doddle!
If you could please like and share the video, that helps tremendously.
I’m off to do a few outside jobs today, I hope everyone has a great Sunday 😉
Very impressive. Always good to see something being used before you spend your cash. Another good, no nonsense review/demonstration.
Thanks for watching!
And thanks for the comment ;-)
I used one of these at work the other day. First time I'd seen one. Was very impressed. Stayed sharp for a long time as long as you take it steady and don't go too fast. It also gives a little counter sink too which is handy
These are awesome, it's absolutely effortless when used in a impact driver/impact wrench!
Thanks for the comment ;-)
That thing really kicks ass when the tip breaks through!
Absolutely, they are brilliant
Thanks for the comment 👍
At the start of the video, I thought "that looks like a really cheap cone cutter.". I was so wrong! That's impressive. Thanks for sharing.
I thought the same to be honest, but after cutting several holes I inspected it, and there was not a mark on it!
Thanks for the comment
I think we all thought that 😆
But what an amazing product. Half the problem is knowing these products exist in the first place. I’d never have even thought to search for an impact capable bit like this without this video.
That’s a great bit of kit. Thanks for sharing. 👍
Absolutely, Thanks for the comment ;-)
That was one impressive demo. Thanks.
You are welcome
Thanks for the comment 👍
Hi, great video. Can I ask what it is in the aerosol can you spray on? And what brand it is?
It's a coolant/lubricant. HMT sent it with the step drill, it makes the drill bit last much longer.

Wow!! Like a hot knife through butter. Impressive piece of kit.
Absolutely!
Thanks for the comment
That's a nice bit. Very impressive.
Yeah, it's a cracker ;-)
Thanks for the comment
Nice piece of kit that is , we've all had done cutters that go blunt in minutes, this looks the dogs , great video
Thanks Mike, yes this is certainly a quality piece of kit. They are not cheap, but well worth the money, as you'll save lots of time.
Thanks for the comment
Hi mate, very impressive drill bit, thanks for the demo, stay safe, best wishe's to you and your's, Stuart.uk.
Thanks, you too!
thank you it looks very impressive
You are welcome
Thanks for the comment
Wowzers !
Yeah, it certainly makes light work of drilling holes in metal!
Thanks for the comment ;-)
Impressive!
Absolutely, I am really impressed with this!
Thanks for the comment
Wow!!!
I need to drill several holes for M12 bolts in an RSj for extension. The cobalt bit I have is good - but compared to this it’s slow.
What a product!! Thanks for sharing.
A RSJ might be a bit on the thick side for a step drill- although I guess you could drill from each side of it (unless you are drilling the flange)
I have recently tried the turbo tip bits from HMT and they are good, but I'm not sure if you can sharpen them yet.

Thanks for the comment, Graham ;-)
Ultimate Handyman I think the webbing is 6mm. Anyway, as you say they have plenty of other products. I’ve been on there website today 😀
Wouldn’t have known about them but for your video, so huge thanks 🙏 👍
Impressive. Would be interesting to see how the performance compares when using it in a standard drill
I'll try it when I get chance. I used it yesterday in my impact driver (not impact wrench) to drill some holes in Unistrut and it absolutely flew through!
Thanks for the comment
Bloody hell 😳
Looks brilliant
Yes, this is super impressive ;-)
Thanks for the comment
i am impressed
I was as well, I'll be using this a lot for certain ;-)
Thanks for the comment
The degree to which IMPACT effect improves the cut is dramatic. Rotation slows down a lot yet the cut is faster!
The tool surface looks perfect, but I bet your lubricant helps.
Try pointing a non contact thermometer at it & see how much the lubricant limits heating.
Do you like the Milwaukee fuel impact drill? It looks very efficient.
Yes, I was quite surprised with the effectiveness of the step drill. I used it a few days ago with my Dewalt Impact driver on some Unistrut and it drilled the holes for fun!
The Milwaukee fuel stuff looks good, I have just bought a new Milwaukee impact wrench and also fuel drill for work, as I use Milwaukee on site. I have had a couple of issues with Milwaukee stuff over the years, but on the whole they make decent stuff ;-)
Thanks for the comment
You gotta try the HMT impactastep cutter step bit. Less steps but they are 1/2" apart and you can drill up to 1/2" thick steel. HMT says those are ideal for an impact wrench while this twist style is ideal in a drill although speed is faster with impact. And yes the reamers are awesome too
I've got one, I used it at work to drill some 14mm holes in a spring steel bumper that was 12mm thick, it drilled the holes in seconds, with no effort
Thanks for the comment 👍
Hi very good demo as always what is spray u r using while drilling metal please let me know
I used HMT’s Speedlube in this video - tinyurl.com/2p9y28tv
Thanks for the comment 👍
I wonder how long it stays sharp as these cone bits do go blunt quite quick. I now normally buy the Lidl ones for about 6 quid a pack as they do last quite well and it works out better value in my opinion. Maybe a good test for a future video?
Not sure, but after drilling several holes, there is not a mark on it.
I'll consider doing a test in future ;-)
Thanks for the comment 😉
One thing i wish manufacturers for these would do is that they'd make each progression colored alternate colors, yellow, black, so we can see each progression easier. I've never been able to figure out which is which rotating, and i have always make the circle i'm supposed to cut on the material, which gets old quick. If the steps would be differently colored, i'd know "oh yeah, it's the 4th step". Just my 2 cents.
That is a good idea, but I'm not sure if it is possible.
Thanks for the comment
what hole punch do you use? I've bought several and they've always broke on me, normally leave them in my pocket or on of the tool boxes
I use the spring tools centre punch, they are not cheap but are very useful-

Thanks for the comment
@@ultimatehandyman going to buy it, its alot cheaper then spending 6 quid every couple of months
@@9zero472 They are good and it is surprising how much force they generate. I used to have an automatic centre punch, but it broke after a few uses and went in the bin ;-)
Will that step bit drill deep enough into a lug to weaken and snap a damaged lug nut?
These are not really suitable for that, as wheel bolts/nuts can be a tough grade of steel, which might blunt the step drill. It might do it, but these are expensive!
I've drilled wheel bolts out in the past, but had to use a special "Artu" multi-purpose bit-
th-cam.com/video/8Rm9fBXIzPg/w-d-xo.html&t
Good video.how u find the cutting lube
It seems very good to be honest.
I've also got a tin of cutting paste from them (but I've not tried that yet)
Thanks for the comment
😊👍
Thanks for the comment
Impressive. Would it be overkill to use it on plastics?
A normal step drill and drill works great on plastic, I'd save these for metal ;-)
@@ultimatehandyman for special occasionsn😁
As others have said, an impressive bit of kit. Used to be an 'orrible job drilling bigger holes in anything in situ! Especially where there was no power easily available.
Thanks Dave ;-)
That's a drill press + drill driver version if want one for a impact driver I know your in the uk but hear in the USA it's a 1/4 hex and you are using a impact wrench
This impact bit uses the Versadrive system, so the hex shank is 11mm. It will fit in a standard chuck, but to use it with an impact driver or wrench you need the Versadrive adapter- holemaker-technology.com/collections/versadrive-adapters
Thanks for the comment 👍
Looks decent 👍 do you know who sells them ?
I think you can get them direct from their website-
holemaker-technology.com/collections/versadrive-step-drills
Thanks for the comment
I personally Require These To Have A Hex Shank To Be Able To use it on a impact driver without the adapter just Like Milwaukee
yeah all my step drives are hex shanks, i couldnt be putting up with that wobbly adapter.
The adapter does seem to wobble, but it does not seem to affect the drilling, once it gets started. Some of the HMT tools need a lot of torque, such as their reamers. I tried reaming a hole a few weeks back using my Kielder impact wrench and it got stuck in the hole. I had to use my Milwaukee from work, surprisingly there was not a mark on the reamer!
Thanks for the comment
Wow! that is impressive, not sure I could bring myself to using it in an impact though, just seems wrong!
Wait until you see the impact reamers LOL
I was sceptical of using it in a impact wrench/driver, but it works brilliantly!
Thanks for the comment
It's actually better than the regular variant for these. Because of the two large flutes, you're asking a lot of your drill and the cone itself, but by "pack pack packing" at it, the cut gets easier. Think of it this way, how do you get material precisely, off, faster? By small rhythmic impacts, or one big wallop that can either fracture the rock or do exactly nothing, because the impact given, is met with equal resistance?
@@aserta Yes but nothing is perfect,you see all that pack pack packing as you call it will have effect on the edge chipping.I dont think these will last or be sharp long if used in impact driver.Reason is simple -its interrupted cut.Lets take a look at a bigger machine -the lathe.If you have a round object on it you will get continuous strings of swarf comming out of it(chip braker makes it cut but its impact less),your knife will cut with same force ,with proper cooling and lubrication it will work for a long time.
Now lets put a square peace of metal in same lathe.Those 4 edges will beat the living crap out of the tip of your knife ,and no matter which material you use (carbide is actualy worse than HSS)your cutting edge wont last long unless you change geometry of cutting edge to positive rake which for effect increases the force you need to do the cutting. But even then edge doesnt last as long and its prone to chipping .
Nothing lasts forever but i dont think(maybe i am wrong)the cutting edge geometry of a stepper drill can withstand impacts for a prolonged time.
The after shot really looked like it was from before you used it (or another one).
I thought that it would have blunted or at least removed some of the TIN coating, but that was definitely the after shot. It still looks like new!
Thanks for the comment
@@ultimatehandyman Thanks for verifying; that's amazing.
@@metallitech You are welcome. Yeah, I'm not sure what kind of steel they use, but it is certainly better than most other step drills etc.
Hi
What’s it like on wood? Thanks
I would not use a step drill on wood to be honest, as it will probably blunt it- then make it useless for use on metal afterwards.
Thanks for the comment
@@ultimatehandyman Thats the silly thing to say ,no wood on earth is stronger than a steel.If the steel doesnt bunt it no wood will thats for sure.
General rule for anything that cuts-as long as the material that cuts is harder than material it cuts you are fine .
@@zumbazumba1 If you use HSS drill bits on wood it makes them go blunt. I thought everyone knew that!
Plasterboard is that soft that you can break it apart with your fingers, but cut it with a wood saw and the blade will be blunt afterwards, the same goes for drill bits ;-)
Where can I get one??
I think you can get them from their website-
holemaker-technology.com/collections/versadrive-step-drills
Thanks for the comment ;-)
@@ultimatehandyman okay thanks I will have a look
Wonder why you didn't mention the price
I didn't know the price, until someone asked ;-)
How long will they last I guess that's the main issue. Consumables never seem to last.
I guess there are a lot of variables, depending on what materials it is used on and how much coolant is used etc. Compared to using a bi-metal holesaw I would imagine these would last much longer, but you also get the time saving advantage and also the ease of use, as there is no kickback.
Thanks for the comment
@@ultimatehandyman Thank you for the answer. I guess there's a bit of swarf to be cleaned up. And once they are finished on steel they might still fulfill a purpose on Aluminium or Wood.
yes, I got a free set of 4 of those from Harbor Freight Tools years ago. I love them. They have lasted years. Considering they were free with any purchase, they are superior to drill bits.
I have the harbor freight bits too but I don't think they are impact rated
only problem i find with step drills is they go blunt fast. I'm an electrician by trade and we go through these fast.
Do you use a lot of lube/coolant with them?
I thought these would be great for electricians, much easier to use than a hole saw or sheet metal punch.
Thanks for the comment
I've not tried these. We just use the regular ones with cutting paste but they can last about a week before they are blunt and we end up piloting. We drill alot of 4mm steels and also purlins etc.
@@DaleMarriott1337 Thanks Dale ;-)
@@DaleMarriott1337 TCT holecutters work great and last long HMT has those as well but with a 2 1/4" drilling depth which typically is not ideal for electricians. I have a dewalt TCT hole cutter set for 7/8, 1 1/8, and 1 3/8 and they have stopper to block from punching through far. I recently got HMT ones and they are very impressive and the reamers are too. I imagine there step drill to be far beyond what you get else where which im going to get and try
y7👍🤓👍🍰
Thanks for the comment, Wayne ;-)
A bit late with the lubrication
It was applied at the start of each cut and during on some ;-)
Thanks for the comment
Holy Shit 100 pounds for a 1 is ALOT.
The one in this video is the 4-22mm one, which is £46.30 (not cheap by any means) but for professionals that would soon pay for itself.
