You are welcome for the info. I know it's a lot to digest but it isn't easy to explain so people can understand.
Check Wiki http://en.wikipedia.org/wiki/Drill_bit
I will try to get pics but it's tough to show the areas I want in a pic and get the right angle.
Yeah, most people freak when I take a new drill and go to put an edge on it. The drill is sharpened like a good knife so anyone can cut something with it.
Ask around and see if anyone has a Machinery's Handbook. I have the 16th Edition and on page 1525 is a great drawing of angles and shapes for sharpening drills. Just look under Tool Grinding if you have a different Edition.
For most people the "normal" grind will work. If you do a lot of drilling you need to sharpen the drill for the job you are doing.
One important thing to remember is when you drill aluminum use liquid hand soap with a little water added. Rapid tap and some others will work but hand soap and water are the best.
Well, I hope I have helped everyone out. I have never used a Drill Doc so I can't say one way or the other. Like most tools it has to do with how it's been taken care of and how one uses it. Sure I can sharpen a drill on a 4" cutting wheel while someone holds the machine but it doesn't do the best job.
