What grits for my new bench grinder

[Joe Cowan]

I have gotten the new slow speed Jet bench grinder. It comes with one 80 grit and one 100 grit stone. I was wondering what grits are most commonly used by woodworkers for their grinders? It seems 80 and 100 is on the course side for sharpening.

The grit size is the least important wheel attribute for sharpening. You will want a friable abrasive particle and a very soft bond so the wheel will run "cool". Crowning the wheel and keeping it freshly dresssed will aid in keeping it running cool. Pink abrasive particle and H bond is a good choice for tool steel in plane blades and chisels. Given these two properties optimumly chosen, it doesn't matter much what the grit is in the range of 60-100. I go from any of these wheel grit sizes to a "fine" diamond plate and then hone with a yet finer grit of your choice- water stone, diamond on cast iron, etc.

Jerry Glaser has a good explanation of grinding wheels on FWW's website. Don't know if the codes he gives are still good as the article is several years old.
