PLUS a bonus hack to help you NEVER AGAIN break the 1/4" pilot drill bit in your hole saw set!
Here you'll learn how to use a large hole saw & a drill press to make two things:
1. a HOLE in the steel plate, the size of the outside diameter of the hole saw, and
2. a PLUG or disc of steel, the size of the inside diameter of the hole saw.
Today I'm after the plug that's left when I drill a hole, but the same exact process applies, regardless of which part you're after.
