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!

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.

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.

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.

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.

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 👍

There is no reason for drilling it horizontally apart from it won't fit in the vice the other way around.

I'm glad the video has helped ;-) Thanks for the comment

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.

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 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.

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 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.

Hi Gary, I'm glad the video helped. I don't accept donations, as I started both my website and KZread channel to help people out, unlike some other KZreadrs that do it for financial gain. Thanks for the offer though, it is much appreciated 👍

I would disagree with your comment about the coolant, it perhaps aided cooling a little but it’s more for lubrication to prevent friction etc ..

Do they make them in a 1/2 size

Not sure, 1/2 is a bit small. If its for thin metal, up to 5mm thick I would use a step drill (they are superb) kzread.info/dash/bejne/i3hhucV6isLfnqw.html If you want an impact rated one (these are more expensive, but well worth the money)- kzread.info/dash/bejne/eoSqkrlphbHKm9Y.html You can also get some that will drill metal up to 12mm thick with ease- holemaker-technology.com/collections/new-products/products/versadrive-impactastep-cutter-metric-sizes

Ideally you want to drill your pilot hole out to 1/4" and replace the drill in the hole saw with a 1/4" rod. This is stronger and keeps the flutes of the drill from enlarging the hole which will widen the hole saw path and make your drilling time longer.

Is this a normal hole saw (normally used for wood), or is it a certain kind of hole, specifically for metal?

@ultimatehandyman

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

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
