Diamond Wheel
I am looking to buy a diamond wheel for my tool bit grinder. McMaster offers them in 100, 180, and 320 grit. Which one would you suggest.

To remove stock you want coarse to mirror polish, fine . Are you aware not to grind steel it will trash the diamonds . If I was to buy only 1 it would be 180 . If you have a Chinese grinder the bolt pattern may be off and axle diameter off I bought 2 different Chinese tool grinders and the diamond wheels had slightly different bolt pattern with flat heads slotting did not seem good idea.so I re drilled the flanges and tried to true up on loose axles .

What are you typically grinding, Jere- HSS, Carbide or a variety of materials? Do you need a specific profile or will a square face suit your needs?

Check out this company.....http://www.wttool.com.....I've bought stuff from them over the years and it's good quality at a reasonable price. Since a lot of tooling is made in China anyway, even private label, it may be worth looking into. I have a diamond wheel made for a standard surface grinder, 1 1/4 dia mounting hole, so made an adapter hub that fits a 5/8 dia shaft motor. I think it is around 120 grit. I finish the carbide edge with a diamond whetstone. I'm a mold maker so used to hand finishing.

Thank you to all.
I want to sharpen my carbide tool bits and create different profiles. I want to have a regular stone on one end and a diamond on the other. Since the HF grinder I have has forward and reverse I can grind both sides of the bit. When you grind a carbide lathe tool, do you remove the body of the bit beneath the carbide on the regular stone and then grind only the carbide portion on the diamond so as not to harm the diamond with the body of the bit? I am not afraid of hole pattern as I have made several adapters for mounting several different types of stones to different machines that they were not meant to be mounted to. Thanks again for your input. This is the most informative sight ever, thanks to the people like you. Jere

There are these for roughing out carbide.

Thanks Bob. I have bin using the green wheel for 30 or so years and want to be able to use the table on the tool grinder to get a more precised angle on the finished tool.
I have ground all my tools by hand since the 60's and I can't figure out why I want to do something different now. I bought a Drill Doctor about 15 years ago and used it once and gave it to my son. I have bin giving it a lot of thought lately and getting older isn't working out for me. I think I'll just stay at 50 for a while and see how that works. Jere
