... Hello, How do you sharpen carbide masonry drill bits? I have a bench grinder. I'd just buy a new one, unless you have a diamond wheel.. The bit insert is silicon carbide, the same as your grinder wheel, so it would likely tear up your wheel. |

Carborundum (fine grit green in color). Any local tool supply company would have them. The tips are low grade carbide. I am retired machine shop owner. Used to grind them by the dozens for my electrician friends. As Roger suggested it may be less trouble and cheaper to just buy a new one. http://www.production-tool.com/html/...s/carborundum/ |

How do you sharpen masonary drill bits?
The bit I am trying to sharpen is 1 inch. Not a throw away bit. Any
suggestions? "F.H." wrote in message ... Michael wrote: Hello, How do you sharpen carbide masonry drill bits? I have a bench grinder.

The bit I am trying to sharpen is 1 inch. Not a throw away bit. Any
suggestions? Like a previous post said, a green wheel on your grinder. Easy done. The grinding wheels cost just slighlty more than conventional but tend to wear down rather faster, so don't use it as a general purpose sharpening tool. HTH Joe |

With these drills if you get close it will work. Frank |

How do you sharpen masonary drill bits?
I sharpen carbide bits now and again with a bench grinder. Light pressure
into the wheel, and try to duplicate the factory slopes and angles. Carbide bits don't have a curved trailing edge, so you don't use the same wrist twist when making the cutting edge. -- Christopher A.

You have to have a special type wheel to cut the mansonry bit edges. The grinding wheel material has to be harder than the bit your sharpening. TURTLE |

Yes , but you never get the fine cutting edge for the bit to stay sharp for anytime at all after being used. The cutting edge will be jagged and not a feather cutting edge. TURTLE |

Turtle you are right that you need a different wheel. Green wheels are the
order of the day for masonry bits. According to my dad, a retired tool and die maker, "the harder the steel, the softer the wheel." ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Keep the whole world singing. . . .
