How do you sharpen you drill bits?

Yes...

I have a copy of the actual book. But I was very concerned that, almost right off, he says to use the side of the wheel. Can't even remember how many times I've been told NOT to use the side of a grinding wheel! So, am I being paranoid ... or is his technique a bit iffy????

Norton Abrasives says not to use the side of the wheel. They should know:

Do's and Don'ts of Bench Grinding Wheels

Can you get away with it a few times? Certainly. However, each time the side of the wheel is used, it is weakening the structure of the wheel. I *never* want to find out what happens when a wheel turning 3,000+ RPM explodes.

One of the best things I have read about grinding drills is by a guy named Joseph Wazoff. Called Drill Point Geometry.

I'm going to check on that title, I actually got close to a good cutting edge today. I still have to learn a lot more, but futsing around is teaching me too. Got some decent swarf in my deep holes.
