The "rolling motion" approaches an art form, by the way. |

The "rolling motion" approaches an art form, by the way. My dad was a machinist all his life. He could take a 1" x 2" stone, and sharpen a drill in very short order. I can't do it yet with my Drill Doctor 750. I remember that twisting action he had. About five or six twisting strokes, an eyeball, some more, another eyeball. Don't have a clue what he was looking at. He musta been good at it, because he a lot of guys commented on it. Never ever saw him used an electrical device, only a stone. Steve |

Maintain a positive rake and symmetry. That is all that is needed.

It's hard to explain, but easy to copy once you've seen it done. Any well lighted tool grinder will work just fine for bits 1/8" and up. Smaller dull ones go in the trash, so buy them in lots of a half dozen or so from a supplier like ENCO. HTH Joe |

Of course, Made in China. These are 3/8" and smaller which I consider very disposable and should last a long time since I'm not a very boring person. |
