So what do you suggest as far as a general purpose grit for carbide tools? ThanksFor sharpening HSS end mills on a surface grinder, I use a 46 H, J, or K Aluminum oxide wheel. For creating a new profile on HSS lathe tooling I use an 80-grit aluminum oxide bench grinder wheel or sanding belt. For touchup of this type tooling, I use a 120-grit wheel or belt, then hone it with a stone.
I think the stand is standard size, the photo did something I think. I was going to put a AL Ox wheel on one side and silicon carbide on the other, the diamond may be too expensive for my needs.I've never seen a grinder stand that small. With your current back situation, that can't be good. Sitting is not good for your back either.
As far as wheels, Al Ox will not cut carbide. You need diamond or silicon carbide. I would go with diamond they run smoother. Get yourself a cleaning stick too for cleaning the swarf out of the diamond.
ok, it looks like it's below your workbench. So unless you have a workbench above 40 inches since a standard workbench is 35, it just looks really low.I think the stand is standard size, the photo did something I think.

I'm not sure which "tool room" stone you're referring to, but Norton does make Silicon Carbide stones for bench grinders and surface grinders.Cubic boron nitride is more expensive than diamond in the west, but from China, CBN is cheaper than even their industrial grade diamond. The concentration isn't' the best, but the binders are tough therefore the wheels are tough. CBN cuts carbide! I have yet to find a vitreous stone that is even remotely useful with tungsten carbide. I haven't tried silicon carbide, Norton doesn't make toolroom stones in silicon carbide. Their premium stones are ceramic alu oxide, still not tungsten carbide capable, but cool grinding and amazing on HSS..
