Looking for source for grinding wheel

[Potashminer]

My apologies if this is not correct forum. I've had a Brownell's Receiver Contouring fixture and appropriate mandrel for a few years. I would like to get the cupped grinding wheel (Brownell's part no. 467-774-187), but the lady I talked to said they no longer carry it, and could suggest no alternative. I did manage to find a DeWalt DW4960 Type 11 cupped grinding wheel, but it is apparently 16 grit and 4" diameter. From the contouring fixture Instructions from Brownell's, they show a white cupped stone, which I would suspect would be much finer grit than 16. Can anyone suggest a source of an appropriate alternative to the no-longer-exists Brownell's stone?? I do not own a mill, so am stuck working with a drill press.

Amazon might have something or else Acklands or Motion Canada depending on what grit you want.

If Acklands does not, try McMaster Carr.

Check out Walter Surface Technologies. I use their stuff exclusively. Huge varieties of profiles & grits & applications.

Yep.

Do some reading about tool and cutter grinder wheels on line, so you have an idea what you are looking for.

Any label on the wheel you have, it may have all the info you need in the part number, if they left the original label in place on the paper blotters on the sides of the wheel. It should tell you the grit, the density, and the bond type. Again, this info is out there, how to decode, etc.

Okay, thanks for the information. Found a possibility at KBC website. Might end up having to try turning a mounting mandrel, but they do show 46, 60 and 80 grit cupped flaring wheels (Type 11).
