Just upgraded my 6" bench grinder to 8" slow speed, and am now looking at getting a CBN wheel. Not sure which grit to get tho. What do you have and what grit would you recommend? I'm thinking of getting just one to sharpen and I'll use what came with the grinder to do any actual "grinding" to get the tool close. Thanks for any and all input.

You do realize those wheels are mainly made for sharpening carbide and other super hard alloys and therefore cost twice as much as your grinder?

Otherwise, I would buy a Rikon 8" grinder complete with white aluminum oxide wheels on sale for $100 and be done with it.

Here is a review I posted on my CBN wheels in January 2014 … I'm still happy with them:

CBN wheels are for sharpening HSS tools … I wouldn't use them on "carbide and other super hard alloys".

If you are only looking to buy one wheel, go with the 180-grit.

Gerry, your review suggests giving the grinder a head start by spinning the wheels, are they that much heavier than regular wheels?

Yes. I haven't weighed them versus the old friable wheels, but they are milled from a single piece of steel and are certainly heftier. It also takes a lllloooonnnngggg time for them to spin down after you shut the grinder motor off.
