I use 46 grit K grade 32A and 60 grit K grade 32A pink aluminum oxide wheels
on my Baldor, which is used almost exclusively for sharpening HSS. The hard
gray wheels that were on it didn't work well with HSS. Remember, the softer
the material, the harder the wheel and vise versa.

I just bought a nice used baldor 10 inch grinder (3PH). It came with some
well used 8 inch wheels. Looking for advice on what kind of grinding wheels
to put on it. I will use it mostly for grinding HSS toolbits.

I think this grinder came out of a school, so they may have put 8 inch
wheels on it just for economy or they may have desired a lower surface
speed. One person recommend a 10 inch wheel for roughing and an 8 inch wheel
for finishing.

When it comes to grinding wheels I belive it buying the right one the
first time. It does not pay to skimp.
