I’m so happy you told me it took a bit longer. I was going to say you are magic. I never get through steel that thick this quick.
Thanks for the comment 👍
This video helped me so much. I had ordered a metal media console from ETSY. They were supposed to drill holes but they did not. So I watched your video over and over and over again. Especially the torque. My drill was not as good as yours and I upped the torque and there was blow back on my hand so I put it back to the number that you stated. I ordered a Klein tool for the punch (did not work that well and danced on the 3rd hole that I drilled. I also purchased 2 in. Xtreme Tri-Cut Tungsten Carbide Hole Cutter and so glad I did. And some cutting oil. I have never did anything like this before and am so Thankful for your video. I watched it again just before I started and caught something that I would have done wrong. The Klein tip did not work as well your your punch too. This was the time when I wished I would have purchased a better drill. By the 3rd hole that I was working on, I was toast but I drilled slow and steady. :)
Very nice instructional. My dad taught me basic things while I was growing up. He never taught me that, but your teaching method is just like his was. Thanks!
You are welcome.

I've been following you for years and always enjoy your videos. I bought (what looks like), that same Dewalt 3-speed hammer drill about 20 years ago and still use it sometimes - that was a quality machine! Mine came with a side handle which I highly recommend when using a hole saw to spare your wrist in case of a jam. I also find that if you run the drill at too low of a speed it can over heat the motor. The motor is designed to run at 18 volts so running it at too low of a speed can cause it to work harder, plus since the motor is fan cooled, the fan needs to be spinning at a good rate to move enough air to keep the temperature down. For long jobs, every once in awhile, remove the drill from the work and run it at full speed to cool it down.
Yes, this is one of the best drills that I have ever owned.
Thanks for the tips and the comment 👍
Motor will be running at usual speed, the gearbox slows down the chuck.
He is forgetting the most important part of drilling with a hole saw. Every so often disengage the pressure and pull it out. Use a brush to remove the chunks of steel clogging the teeth of the saw.
Absolutely critical when drilling deep metal holes, a little jet of air or liquid helps get the debris out of the groove as well.
Good tip
For weeks I had been putting of drilling a hole through the housing of a heating unit. (I was a bit intimidated by the task.) Today I watched your video, picked up some lubricant and went to work on the housing. It went perfectly. Thanks for the video.
You are welcome.
Thanks for the comment and well done ;-)
I'd like to comment that the torque selector, when driving in Phillips head screws, is also a great feature to prevent the slots in the screw head, as well as the tip of the Phillips driver bit (over time) from getting stripped once that screw is all the way in and not needing anymore applied power twist for the finish, as it will be indicated by the "you can stop now, in far enough" clickity clack clack sound of the drill.
Helpful- thank you- gives me confidence to have a go on a project tomorrow . all the best. Lee
Good luck with it Lee.
Thanks for the comment
Nice demo chez, i do exactly the same with the torque control when drilling large holes in wood with holesaws, and auger bits, it's better the twisting your wrists up if they jam.
StyXSISoriginal
Thanks, Yes the torque control is very handy. In the past I have only used torque control when screwing but it's much easier using hole saws with it ;-)
Big man, i could watch these videos all day mate.
Thanks for the comment ;-)
Great tips. broken many bits and hurt my wrist plenty of times. Thank you for the tips.

Any tips on cutting with a hole saw in brass? I feel like cutting fluid doesn't work on non-ferrous metal
All round a good practical demo of how to do it - Thanks

Thanks for the comment
Thank you so much for this video. I need to drill a hole in metal exactly like this. I never knew about putting the drill into torque mode when using hole saws. Luckily, the metal I'm drilling into is only about 2-3 mm thick, so I'll have an easier go at. Cheers!
Thanks for the comment 👍
low feed, high speed and cooling, nice work old man.
Thanks for the comment ;-)
Great video! You answered so many questions i didnt even knew i had!
I’m glad you found the video useful

Great tip to use the torque settings for drilling, I never thought of that. Cheers. N.
Neil George
You are welcome Neil. I have been doing a few holes in stainless on site and got sick of nearly breaking my wrists so started to use the torque control- it worked well ;-)
In stainless??? Rather you than me mate. Are you a fitter in a Steelworks? the reason I ask is although you have a Lancashire accent (I know there isn't a strong steelworking area around there) alot of the tools you use are similar to the ones I see the fitters using around the mill. N.
Neil George
I subcontract as a maintenance engineer at two local chemical plants, one of the plants has had a new production line installed and I have done quite a bit of installation/remedial work on it. Most of the machines are stainless including the wall partitions and control panels, so I have had to get the hole saws out a few times!
Thanks for the comments ;-)
I reckon you really are an asset to them, your knowledge seems endless. I have learnt more from your channel than 13 years in education. Thanks alot mate. N.
Neil George
Thanks Neil, I have learnt a lot from the people I work with when I am on site ;-)

Useful and highlight your clips

Using the side handle may have been a good option too here,to help you keep control of the drill,should it twist violently.
Bosch has a 36v combi,with rotation control that senses the twisting action of the drill should it bind,shutting it down immediately.Very pricey though,so no thanks,lol.
Great advice about using the torque control,i would never have thought of it...youve saved some strained wrists with this!
PS...just bought the new DCD995 Brushless combi...its a brute,lol!

Some Bosch drills are very expensive, but I do believe Bosch make the best SDS drills (apart from Hilti)
I keep looking at that Dewalt drill, but can't buy it yet as all my Dewalt gear is still going strong!
This video is amazing. Thank you so much!!
You're so welcome!
Thanks for the comment 👍
Excellent. I wouldn't have thought that could be done like that. Thanks
Bruce Dobson
You are welcome
Thanks for the comment ;-)
One thing I thought of afterwards is, what's the condition of the blade once the hole is cut?
Bruce Dobson
Absolutely fine. I have had this set of hole saws for probably 15 years, possibly longer than that!
thanks for the good video sir
good job. I like ur precision
Thanks for the comment ;-)
great job with the oil on the hole saw .. Lots of folks think they don't need oil with hole saws , But they need lots of cooling !!
Absolutely, it's critical if you want the hole saws to last. I have had my set for about ten years and they still work well ;-)
Thanks for the comment
ShawnMrFixitlee This is exactly the info I came here for. I have some serious holes to drill tomorrow and was wondering about speed and oil use. Perfect lesson.
Have done 6" holes in metal that thick using a cordless drill with/ handle. Exhausting work ,hurt my wrist a couple times before I figured out the torque control trick. Highly recommend using the trick shown here if you can.
I can imagine that being difficult!
Thanks for the comment
A hole saw blade may grab when it first engages the material being cut often breaking the pilot bit. I dill the pilot hole first then engage slow and careful. But the most helpful tip is to install a 1/4" rod in place of the pilot bit. Drill pilot hole with a separate 1/4" bit, then use the hole saw with the rod as a pilot. It's alot cheaper than buying a buch of pilot bits.
Thank you. A very useful video. I will need to use a hole saw to cut holes for some skin fittings in the side of my Narrowboat (6mm mild steel). One question though: When cutting or drilling holes - roughly how much forward pressure should you apply to the drill?
Not too much pressure, or the holesaw will bite. As long as the torque control is used, you should not have a problem. When cutting the hole you'll be able to tell if you are pressing too hard as the drill will slow down.
Thanks for the comment 👍

I have a question.. do you think is possible to drill a 20mm hole in a 15mm thick piece of brass with a Dremel 4000? Thanks in advance!
I'm afraid I don't know much about Dremels, as I have never owned one!
Thanks for the comment 👍
That was very helpful sir.
Thanks for the comment 👍
impressive. Although it took alot longer than the video shows.Lubricant and proper torque seem to do the trick.Well done.
Thanks for the comment
Thanks for the tips! I see you are using a Bosch holesaw, is that from the Progressor set? I thinking about buying those and was wondering if they are any good?
+Paul J Kimberlee
You are welcome. That hole saw set is just a standard Bosch bi-metal hole saws set. The set is over 15 years old but most of them still work well.
Thanks for the comment
I do this quiet often, but never on a vise. I put a plywood underneath the sheet, and firmly clamp it down on a table horizontally. Its way more safe, way more efficient, and the lubricant also stay as it suppose to lube. On the half way down i flip the metal, and start form the other side. So i don't let the friction slowing down the process, i give less torture to the saw-bit and the drill as well.
Yes i know there will be a tiny rim in but thats not a big to get rid of it if its really wished.
Its a Bosch Bi-metal holesaw.
They can be used on metal or wood, but wood tends to make them blunt.
Good point
Great video! Do you need a hole saw specifically for metal or can you use any hole saw as long as you use the lubricant?
RobBurnsDrums
Most HSS hole saws will work, but I always tend to buy Bosch hole saws as they seem far superior to any others that I have used. A slow speed and lubricant/coolant ensures they will last a long time ;-)
Bi-metal hole saws are best, such as Bosch. They can be used on most materials including plastic, wood and nonferrous metals.
Do you use the same method for drilling stainless steel?
Great video's, thanks for posting them!
Yes, but you have to watch stainless steel as it has a tendency to bind and grab the hole saw.
Stainless is tougher and you typically would run slower speed bigger diameters slower rpm. That's the simplistic method. Machinist use surface feet we use that to tell us what rpm to run on rotating cutters.
While I regard myself as a better than average amateur mechanic, there is always room to learn. Following your method I was able to open up a clean 1 and 1/2" hole in the bottom of a steel, elevated fire pit. This will allow enhanced burning characteristics. Many thanks for your tutorial!
You are welcome
Thanks for the comment 👍
Your way, the right way. Thanks for the video.
Thanks for watching!
Great Video.
Thanks for the comment
Is there any reason to drill horizontally like this? Just to get more pressure on the drill easier? Very helpful video btw, many thanks for doing it.
There is no reason for drilling it horizontally apart from it won't fit in the vice the other way around. It's much easier if you can lay the material flat as the coolant does not keep running off the same, you can also use your body weight if you can get above the work piece.
I'm glad the video has helped ;-)
Thanks for the comment
Good work!

I have a regular black and decker drill set.
Can I find just those hole cutting pieces and snap them on my drill or do I have to buy a complete whole new set specifically for this capability?
(Working on wood projects so I need small holes done)
you need an arbor for the hole saws to connect to
Down to earth chap, no hype, wonderful.

Awesome video bro!!!!! I need to do this to the strut tower on my car, what dewalt drill is that???
It's a Dewalt XRP 18v drill (the one with the fully metal chuck), I can't remember the model number, sorry.

I need to drill a 2 inch hole through the rear bumper of my truck (to install the plug for a towing wiring harness). The bumper is pretty thick steel. I see you're using a Bosch drill bit. Is that what you recommend?
Yes, any decent make of HSS/bi-metal hole saw should drill the hole. Just take your time with it and use a good lubricant/coolant and it should be fairly easy.
Best of luck with it ;-)
The project was a success. Check out the results here: goo.gl/photos/66t4QuirAr1Npesq5
Thanks for the advice!
Can u tell the model on the drill? im looking to buy a dewalt cordless drill for something similar in this video. any sugestion? maybe something in the new line like flexvolt? thanks for your time
The drill used in this video is no longer made, but I think the closest model to it is the DCD996- fave.co/2O4PaqJ
Which can of course be used with the Flexvolt batteries.
Thanks for the comment
That is very good tips....Sir, going to take new hand drill machine like as in your video...Sir, can you send me some machine models/details set. I need upto 35mm hole on 2mm steel plate. Can you ask me witch one batter for that. Thank you.
The model looks to be a DeWalt drill......maybe a 14.4V or higher.
I'm going to cut the end of my motorcycle exhaust with a circular hole saw as part of a KLR650 mod to make it bigger. I've never used one before though. I obviously can't drill a pilot hole since the exhaust has a hole in it already. I'm assuming I can leave the exhaust on the bike to do this? How can I keep the hole straight? Do I need to use WD40 or some cutting oil? Thanks!
You can get an arbor called an "oops arbor" , which allows you to use two holesaws on the same arbor, this means you can put a holesaw of the diameter of the original hole, then the larger diameter holesaw that you require on the same arbor for enlarging holes like this.
I drill a lot of holes in steel with a cordless. Thickest I’ve done is half an inch - i prefer a hole saw over a twist bit as it means moving less material. I found this video while looking for tips on keeping teeth from breaking on my carbide hole saw. (It cuts faster but is more expensive)
For lubricant i use gear oil or soap. Yes, soap. It sounds weird but it’ll work better than most oils for tapping small things.
👍
Great vid thanks
You are welcome.
Thanks for the comment
Great video! Right on!👍👌👊👍👌👊👍👌👊
what type of hole saw did you use to cut that metal? I need to cut thru some stainless steel that .025 thickness.
+Ron Davis
Stainless is a real pain, so ensure you use the torque control and plenty of coolant/lubricant as it can snatch violently.
The holesaws that I used were Bosch Bi-metal.
Best of luck with it ;-)
Good day! Could you tell me if there's a definite way to know if the hole saw i found is for wood or for metal? Still kind of a amateur here honestly
Does it have a manufacturers name on it or any markings?
If it says HSS on the side, it should be ok for use on metal.
Thanks for the comment 👍
Thank you for the help man
Hey,
Would you think round metal ducting could be cut with a evolutuion rage r255sms miter saw?
Or would it crumple up, jam the saw and cause damage and possible injury? Thanks.
I'm not sure, it will definitely cut thin wall tubing, but because ducting is so large you would not be able to go straight through in one cut, so you might have to make a cut, then stop the saw and rotate the ducting. I have cut some thin boiler flue material on the Rage 2, with no problems, but that has a much larger diameter blade- ua-cam.com/video/zI09uLXTvmE/v-deo.html

I’m trying to upgrade my boat compartment latches. The ones in there now are 1” diameter. I need a 2” hole. That means I need I wonder have a pilot to help guide the hole Saw. Any thoughts on how I can make this work?
This might help-
ua-cam.com/video/jurSZR1Se6A/v-deo.html
Or you can get a special arbour for this purpose, called an oops arbour-

Hi Chez, how would you recommend smoothing out any rough edges in the hole?
You might have to use a die grinder and abrasive insert-
ua-cam.com/video/wLV7QpmzFOA/v-deo.html
Or a sanding bobbin in a drill - fave.co/3v7PFrM
@@ultimatehandyman Thanks!
The Saw teeth tends to lock up when the hole saw teeth are almost through the sheet or when some to the teeth has cut through. Is it advisable to start at the other end at this stage or make a starter cut from both sides?
+Winston Clifford Yes, you can do that ;-)
I do that often to help remove the plug out of the hole saw if I don't need an absolutely clean hole.....quite often the pilot hole has enlargened slightly so when you drill through the other side, the two holes don't line up and you get a small ridge in your hole.
If you want a nice clean hole, drill through from the one side.
This is what I have found anyways, never tried drilling steel with a hole saw, just maple which is pretty damn hard in itself....
Ultimate Handyman that hole saw looks like a wood cutting hole saw.
They can be used on wood, but are mainly for metal use.
Thanks for the comment
Ultimate Handyman so it's a hole saw specifically for metal?
helpful video thanks!
Glad it was helpful!

HI I am going to be cutting inch plus size holes in three dozen soda containers. My problem is most of them are too big for my vise. Any thought on how to secure them on a work bench.
+James Reed
I'm not familiar with soda containers, so I googled it but all sorts came up from metal cans to plastic bottles!
If you are trying to drill holes metal cans it might be easier and give you a cleaner cut if you use a step drill- ua-cam.com/video/YD-WcAZ_ynI/v-deo.html
As for clamping something down, it's hard to say without seeing it. If you can show me a picture of a soda container I might be able to help more ;-)
Would I be better with a 14 cutting drill bit for 2 holes in 1mm thick sheet metal??
I have 7 PK of Holesaw on the way
For thin metals, a step drill is often best- ua-cam.com/video/YD-WcAZ_ynI/v-deo.html&t
You took approx 8 mins for the task.. Damn.. I was making a pilot hole yesterday for the same on a 3mm sheet, took half an hour.. Another half an hour later I was left with a pilot hole, a hard to see circular scratch and a bruised back..🙂🤗
You ned a really good quality hole saw, some of the cheaper ones are not up to the job. Also make sure you use plenty of coolant/lubricant, to get the best life from the hole saw.
Thanks for the comment
how to choose hole saw cutter for metal /stainless steel.? Can HSS hole saw work or do I need carbide tip hole saw.?
Carbide tipped are better for stainless steel- ua-cam.com/video/1l9sqDMpbUU/v-deo.html
HSS will work but the hole saw will quickly go blunt and stop cutting eventually.
Thank u
Hi what hole saw are you using to cut through the steel. I want to make sure I buy the correct type
It's a HSS holesaw, in this video I used a Bosch one. Try to stick to good makes such as Bosch, Dewalt, Starrett etc.
Thanks for the comment 👍
Are you using a standard hole bit for cutting wood?
I used a HSS bi-metal hole saw as I have a set like this- fave.co/2hqeMSd
You can use them on wood or metal but they go blunt when using them on wood, especially chipboard etc.
1:10 other video show to put the machine on lower (not lowest) speed for smaller diameter holes, which is correct now ?
The larger diameter of the hole saw- the slower you need to go 👍
Any tips on how to do the same with an Everlast plasma cutter?
Sorry, I have never used a plasma cutter, as we only use the gas axe on the sites where I work.
Thanks for the comment
I notice you only spay the coolant on to the work piece but not the drill bit (hole cutter) most of the sprayed component just runs off, is there a reason you don’t spray the actual drill bit at the same time.
I have never done this type of work and only viewed the video as I really enjoy all that you post and learn lots.
Thanks
It's difficult when drilling a vertical piece as the coolant runs off, it's much easier if the work piece is horizontal. You can spray the cutter if you like but it might get thrown off when the drill rotates.
Can we use this drill for cutting circle by holesaw of 8inch in hchcr d3 tool steel annealed
No, I think you might have to take that to an engineering workshop.
Thanks for the comment 👍
can i drill through the wall of a stainless steel bucket with a wood hole saw bit? I think its about a 40mm bit, designed for wood. will it be damaged beyond repair?
It will probably damage the hole saw beyond repair, I'm afraid.
Even normal HSS hole saws struggle with stainless.
These work well though- ua-cam.com/video/1l9sqDMpbUU/v-deo.html
I want to drill about a 2 inch hole into a speaker grill on my motorcycle to mount 2 inch tweeters . Is this the same process? Steel mesh speaker grill.
No, you have to be really careful with mesh, the hole saw teeth can bite into it and rip it.
The only way to successfully cut holes in some mesh is to firmly clamp it between two pieces of timber etc. Then cut straight through one piece of timber and the mesh, until you get into the last piece of timber.
There are a lot of variables though with mesh size and teeth size on the hole saw, so sometimes it might be possible to cut right through it, without the timber.
@@ultimatehandyman thank you!
never thought of this thanks
You are welcome
Thanks for the comment 👍
Small tip: drill a through hole right on the inside of the ring you are cutting. That way the chips get pushed out on the backside rather than clogging the saw.
Thanks for the comment 👍
I am attempting to cut a hole into some 3/16" steel. Can I use motor oil as a cutting fluid or should I use actual cutting fluid? Thanks
+09ThunderOne You could do, but the fumes could be toxic, so best to use cutting/tapping fluid or even water.The oil will be ok in a well ventilated space as long as you do not breathe in any of the vapour.
+Ultimate Handyman thanks. I think I'll just drop by my local Ace and get some cutting fluid. I know there are several types. Should I get a specific kind for cutting into 3/16" steel?
+09ThunderOne
Any cutting fluid will do, I don't think they make different types for different thicknesses of metal.
Good luck with it ;-)
Very helpful, I drilled two holes successfully
Excellent!
Is this a normal hole saw (normally used for wood), or is it a certain kind of hole, specifically for metal?
It's a bi-metal holesaw, they are designed for use on metal, but can be used on wood- although it tends to make them blunt, if you use them on wood.
Thanks for the comment
@@ultimatehandyman thank you for the quick reply. You really helped
Thanks for another good video. Quick question: could I use wd40 or even water when drilling into metal? Or does it have to be a specific type of lubricant?
Faisal Y
Anything is better than nothing, water, WD40 or oil can be used but for best results a dedicated coolant/drilling/tapping fluid is best.
***** CT-90 fluid is good,you can also get it in a foam.
animal79thecat
Yes CT-90 is excellent, I often use that at work.
Thanks for the comment
What kind of Dewalt drill is that??? Looks like it has a square plug in the bottom battery. I’ve only ever seen the oval shape plug in battery??? And what voltage is tha battery???
It was the DC988, the newer XRP Li-Ion batteries were a slightly different shape than the original Ni-cad batteries.
www.dewalt.com/products/accessories/batteries-and-chargers/batteries/18v-xrp-liion-battery/dc9180
That was a brilliant drill, but I sold it then I could upgrade to the newer XR battery tools.
The battery was 18v 2AH, if I remember rightly
Thats a good tip about the speed. I drilled a few holes, and didnt know that, so used the slowest speed on all bits. next time.....
+B Cook Thanks for the comment ;-)
+B Cook HSS into mild steel you want a peripheral speed of 100 surface feet per minute. You calculate that with this formula SFPM = (PI * DIA * RPM) / 12 So here that worked is 100.8 = (3.1415927 * 1.75 * 220) / 12 close enough.

I’ve got 4 holes to drill through 10mm steel. Is it worth trying with a hole saw or should I buy a rotabroach?
A decent holesaw will do it, but if you have a mag base drill the rotabroach will be much easier and quicker.
@@ultimatehandyman My dad has a mag drill. But I’d have to buy the new bit. Whereas I have the holesaw already.
Thanks for your video, I’ll give the holesaw a go.
Thanks for the video =)
My pleasure!

How would this work on an aluminum shed?
It will be much easier to cut a hole in aluminium, but you have to watch for the aluminium binding to the hole saw teeth.
thanks.
Can you tell me exact name of material you are drilling thru?
Is it A36 mild steel?
Not sure, all I know is that it is mild steel plate.
Thanks for the comment
@@ultimatehandyman
Is it strong? I mean Not bendable?
If use this to drive bearing into hole, is it going to bend?
It is strong, but ductile (it won't shatter- like hardened steel).
We sometimes use mild steel drifts for knocking in bearings, but most of the time we use a brass drift.
I hope this helps
I got 1/4 plate of cast iron and I tried every bits I have it’s so hard to go through the steel what’s my options and the better bit
You need a hole saw that works on cast iron, like one of the starrett ones used in this video- ua-cam.com/video/xm0GGDsw2OU/v-deo.html
