Congrats! With the right wheels, that will grind HSS just fine. They work well for brazed carbide tooling, which is what I think they were intended for. For inserted carbide, an Accu-finish works well.

Expensive tool, and that one looks brand new! Very nice.

thanks for the kind words and advice.....

Mikey, I do a lot of Business with Baldor I mentioned to my salesman a month or two ago that I wanted to start grinding HSS this was sitting in my office this morning!!!!! I couldn’t justify buying something like this personally it floored me. Any advice on wheels would be much appreciated.

You have a really nice salesman - that is a $2,000.00 grinder! Which I do not own ... :(

If you're going to grind HSS, the best wheel to get would be a CBN wheel. Not much choice for a 6" cup wheel with a 1-1/4" arbor and 1" wide face. Shars has some: http://www.shars.com/products/abrasives/diamond-cbn-grinding-wheels/6x1-d6a2c-cbn-plain-cup-wheel

Maybe see if they have a coarse wheel and a fine one. I know that 80 grit will shape a HSS tool and I would guess that a 220 or finer will get the coarse marks off.

Aluminum Oxide wheels are plentiful. You'll have to ask the guys with a tool and cutter grinder for recommendations.

I don't use wheeled grinders for tool grinding; I use a belt sander. Do you happen to know the Wilton or Burr King salesman? :p

You can grind end mills and drill bits with the right set up with that machine. You suck imho.

I have the same grinder you will be very happy with it after a quick learning. I have a a white I believe aluminum oxide on one side and a 180 grit diamond on the other. The aluminum oxide grinds hss very well and leaves a mirror like finish. The diamond plows through carbide also. The diamond will grind hss but not for it as it will degrade the wheel fast. You can also use a green wheel high I think is silica carbide maybe. My favorite has been the white but I don't have a lot of experience it just works good.

Sorry their are no markings on hub of wheel. Wheels came with grinder so Idk what grit. To me it’s a fine 180 or 220. I see the same composition on a lot of tool grinders. Leaves nice fine finish. Hope it helps somewhat.

Wow googling shows they are getting hard to find for some reason. And thank god I got two with my grinder cause they cost more than I paid for my grinder. I see the silicon carbide “green” wheels are available and it looks like I was wrong on grit size. The AO wheels I’ve seen are 46,60,grits.
Here’s one from MSC
