Sharpening drill bits
Posted: Mon Apr 24, 2017 7:53 am
Contrarily to what some people say, drill bits are not cheap, especially not the good ones. I always see tons of drill bits at my local flee market but I never buy them because sharpening drills is something I've always considered too difficult to do without a special setup (that I can't afford or even justify seeing how a good bit will last for years in a pipemaking shop).
Today this video changed everything for me:

This guy is one of the youtube machinists that I follow and here he explains very clearly how to sharpen drills. I found the combination square trick to be amazingly useful. Of course the smaller the bit the more precise you need to be, but I just took a totally beat up 13mm bit to practice on and in a couple of minutes I had it sharpened so that the first test cut in a piece of briar gave me a perfecly smooth hole measuring 13,07mm. I feel I'm a better man now
