Drill Doctor 350X!
Maybe it was a waste, but it was only $50 and I enjoy doing things
right. Should the diamond grinding wheel or the bit being sharpened be wet with some liquid like silicon or WD-40? I also made a channel to help cut my aluminum flat bar forks. Haven't used it yet, but it will help do it right. http://www.flickr.com/photos/27532210@N04/ |

It is not diamond, it is CBN. i I also made a channel to help cut my aluminum flat bar forks. Haven't used it yet, but it will help do it right. http://www.flickr.com/photos/27532210@N04/ |

The chemistry isn't compatible. (Something I learned by interviewing wheel manufacturers a decade ago.) Ordinary soluble oils are recommended in production and toolroom applications. -- Ed Huntress |

Don't lube the drill doctor.
It is best not to practice to many times with expensive stuff :-) Martin On 5/3/2012 4:18 PM, John Doe wrote: Maybe it was a waste, but it was only $50 and I enjoy doing things right.

Drill Doctor 350X!
That conical shape won't work very well, but they have
another cut that will. I've recovered a broken 3/4" drill I got for free. I first turned it like that and then cut the cross point. Another one, I corrected to that form and then hand ground the flats on it. What is the other - cross point ? something like that.

What is the other They are the same 1/2 inch drill bit, with different lighting Number 2 is after another grinding. http://www.flickr.com/photos/27532210@N04/ I might try sanding the cutting edge with a rotary tool. That would be my first use of a rotary tool sanding paper disk. - cross point ? something like that.
