Thread: Big Holes in Thick Plate?

Ask Santa for a set of them for Christmas---you'll use them a lot around car building--the bigger ones have got to be run slow to keep speed down

You can use a plasma cutter if you or a friend have one. Make a template with 1/4" plywood .

...yeah, every time I try to save money by not buying the right tool it costs me in the long run. I save money by buying an incorrect tool but then I end up spending more when I STILL have to buy the correct tool. Or I ruin the part..... Just buy a hole saw. "buy once, cry once".... Bill

Yep, holesaw, and 1/4 isn't all that thick. First drill a pilot hole like 3/16. then run the 1/4 inch holesaw pilot drill into that hole and start cutting. I use water and soap for lube, but many use cutting oil. I just don't like oil on parts I am going to paint later. By starting with a smaller hole than the 1/4 inch one you get a truer cut as it won't wobble when the hole saw starts to cut. Home Depot and Lowes even carry good ones like Rigid.

BTW, CLAMP DOWN THE PIECE YOU ARE CUTTING. I recently wrapped my arm around the drill press when the holesaw grabbed the piece and spun it and me around the arbor. They give you NO WARNING.
