Crowned CBN (Cubic Boron Nitride) grinding wheels provide a precise, clean, and cool-running alternative to bonded abrasive grit wheels. We worked with Woodturners Wonders to design a wheel specifically for hollow-grinding chisels, plane irons, and other woodworking tools. Joel has long been a proponent of hollow-grinding chisels and plane irons, because it makes honing so much easier. However, for many folks even high-quality bonded abrasive wheels are too dusty, difficult to maintain, or challenging to dress.

From the outset we knew we wanted a wheel that had all the advantages of a perfectly dressed bonded abrasive wheel AND the advantages of a precision CBN wheel. It would need to mount easily and safely onto the 1/2" arbor of a 6" Baldor Bench grinder. Even with such sky-high goals we have been surprised at how these came out - easy to use, and unlike some wider wheels these will run without the need to permanently remove the protective wheel covers, making for a safer machine.

We've got a CBN wheel mounted on the bench grinder in our workshop, and it's a breeze to use. The slight crown of the wheel gives a predicable first contact area for free hand grinding and gives loads of extra control to grind predictably and also prevent accidentally overheating the corners of your tool. Because the machined aluminum wheel is precisely round, there is zero tool chatter, and the grinder itself runs more quietly.

CBN is the second hardest material in the known universe, second only to diamond, but in powered grinding applications it is actually more durable than diamond because it doesn't react with iron - as the carbon molecules of a diamond will. That means you can grind to your heart's content on a CBN wheel - HSS, A2, D2, Powdered Metal, O1, W1, even carbide. It has another welcomed property that bonded abrasive wheels don't have: CBN and the aluminum wheel absorb heat instead of reflecting it back into the tool. This makes for very cool grinding, and with care you can even grind to a wire edge without dunking the tool in water (although we don't recommend it, cowboy).

If you've been looking for the next evolution in grinding for woodworkers, this is it.

Arrived in a few days ,packaged very well, and cuts like a dream Only problem i had was my fault. I did not measure my arbor size and it was less than 3/4". Lucky for me I have a metal lathe and quickly made a bushing. Advise to all is to check your arbor size.
I own this product.

Many things are made in China and then imported into the country because of costs. Most can't afford a CBN wheel if it is locally made, how about, say, $159 apiece? As long as the quality lasts, who cares. (By the way, check where you laptop or computer which you used to send your comment is made. China or Taiwan, most likely.)

This wheel is awesome. Super cool grinding (no need to quench while working), nice crown makes the contact point pretty reliable. Works well on my older 3600 RPM grinder. It remains to see its longevity, but it's showing no wear after putting a new hollow grind in just about every tool I own.

Why does everything have to be made in China?
