This is the first of two videos that will teach you how to hand sharpen a drill bit using a bench or pedestal grinder. Part one introduces Barry Young, a machining instructor at Bates Technical College in Tacooma, WA. He demonstrates how a drill gage is used and shows examples of some poorly sharpened drills. Barry also shows some drill bits that were properly hand sharpened and he compares them to some that that were sharpened using Darex and Drill Doctor sharpeners.
In the second video Barry Young moves to a grinder and demonstrates the actually sharpening process.
There aren’t many videos that will show you how to hand sharpen a drill bit and these two are by far the best. It will take you about fifteen minute to watch them both but it will be worth it if you really want to learn how to do it right.
