Drill Bit Sharpening
I've been using my 3/16th bit to thru drill on my lathe with some rock maple and have noticed that it has become rather dull. How do I go about sharpening a drill bit? Thanks

Sharpening drills is not something you just do!! There is a skill involved. If the drill is not sharpened properly it will not drill in a straight line.
Most DIY'ers get the drill doctor set up. Or you can buy a pedestal grinder and give it a try.
If I was you I would check the yellow pages for a sharpening service. Then I would buy a few more of the same drills. When a couple are dull and you have one in reserve, take the dull drills to be sharpened............or ask someone to teach you to sharpen them.
Hey I am not trying to be a hard a$$. I'm just telling it like it is. I don't want to see you mess up your drill and possibly ruin a plug.
Good luck!

What is the difference in performance of the 2 angles.does one bore faster(the flatter one) an one straighter.( the steeper one).I heard some good things on the drill doctor. But if I remember they are kinda pricey.

Drill angle
In metalworking the harder the material the flatter the angle. Although each material warrants slightly different sharpening methods. Wood tends to have a more pointed tip. You can sharpen brad point drills with a small file or stone following the contour of the cutting edge. Usually in wood the drill just needs a touch up on the cutting edge unlike metal where the drill edge usually melts or breaks and needs more extensive sharpening. Sharpening by hand is not that difficult you just need to practice and make sure both flutes of the drill are the same length, you can measure them or use your eye. Paul
