I'm happy for you. You must do a whole lot of drilling to need a drill bit sharpener. How much drilling does someone need to do before the bit needs sharpening? That's an interesting question, and one I have never ever considered. I have the normal selection of drill bits and spade bits for wood, but I have never needed any of them sharpened, and I have done a bunch of work over the 45 years or so I have had most of these bits.
What is it you drill so much? Inquiring minds want to know.
