I would go with a rougher wheel on one side, probably 36grit grey alum
oxide and a white alum oxide 80grit for finish grinding. I also like
the SG blue wheels but I can't find them in 10" for bench grinders.
Unless you want to make up an adapter for a 3" center :-( They work
really well on drills and HSS tools. You also want to make up some kind
of ,ount/guide so you can use a diamond dresser on the wheels to give
you a smooth flat surface. I picked up a Lee Valley tool rest years
ago, its very adjustable and comes witha slide you can clamp tools into.

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.
