Anyone ever use a Drill Doctor to sharpen their bits? My wife bought one for me over 20 years ago (even came with a VHS instruction tape ) and I finally used it yesterday. I had a broken 3/8” bit that I sharpened, I was surprised how well it worked! Used it to drill 18 holes through 1/4” stainless steel, it worked like a charm.
