I need to drill some 21/32 holes with a hand drill, not accessible to drill press.
I do not have a reduced shank 21/32 drill bit and new they cost $30+. I have a 21/32 straight shank drill bit, but it is too wide to fit any of my handheld electric drills, which go up to 1/2".
I thought I could reduce a shank of that drill bit by simply chucking it in a lathe and taking off some diameter with a carbide tool. What are the drawbacks, if any, of doing so?
