That is amazing! Great explanation and demonstration. I'm gonna buy a cheap bi-metal hole saw today. I only need to make a 1" hole in 1/4 plate. Thank you for sharing this!

I've seen this hack done on wood numerous times. Not sure when I picked it up but you do an outstanding job of explaining. I've even used this for oscillating saw cuts seems to help. Thanks for the video and hack

I was just depressed since I was looking at a 1 in cobalt drill bit I needed to cut a hole in my modified piece of metal to fix my 6 in gate valve. Then I saw your video! I can use my bimetal hole saw to cut in steel by using a dill for a waste dump for the metal shavings. I would have never thought of this simple genius idea if I lived 1000 years. Thanks much.

I was wondering what is the best way to make a 32mm hole in a 2mm thick steel plate and since Im making just two holes this is the cheap and simple solution for me, this video was very helpful and you covered all my questions, thanks, and of course +1 like!

Hello, I am going to try to use this technique to cut a 3 1/8 inch hole in a 1 inch thick piece of steel, I am making a home made flathead engine. My “block” is going to be a piece of 3 inch steel pipe with the 1 inch thick plate welded on top to house the valves, but I need to get a 3 1/8in hole in it to slide over the steel pipe. Then it will be welded onto the pipe, and then a homemade cast iron cylinder sleeve will be made to fit in it. If you read all of this and want to see more I have my previous attempts at making a homemade engine on my YouTube channel that I’m posting this on. I am trying to make as much of it as I can with 3d printing to!

[baohoainguyen]

Awesome video, thank you so much. This solves a very basic problem.

[tetsubo]

Thank you so much. This is going to make my life so much easier. What HP is your drill press? Thanks.

I have experienced the same, but I never bother myself if I cannot finish it, I'm thinking of going to a machine shop to get things done. Your wonderful explanation and idea are making me so dammed; I throw my hole cutter away. Thank you anyway, I will try.
