CBN #80 grit 200 mm (T4)


All-aluminium hub

Abrasive: Cubic boron nitride (CBN)




Our square edge #80 CBN wheels is the coarsest available in the world for wet sharpeners – now also available in a 200 mm version!

We’ve developed the #80 for beveling newly made knives, sharpening grossly neglected very dull and chipped blades, and re-profiling bevels to a lower angle.

If you often repair dents, reprofile bevels, or do first-time sharpening for knifemakers, you will benefit from the extra coarse #80 wheel for quick steel removal.

Using #80 susbtantially reduces time in these time-consuming sharpening operations.

It is also perfectly possible to grind on the side of the wheel if a completely flat grinding phase is desired.

Our CBN wheels can be run with common running water from your house or workshop tap thanks to the special embedding technology. Note that if you run CBN wheels of other makers with water, the CBN coating may detach from their wheel base.


Cubic boron nitride (CBN) properties include extreme hardness, stability under heat, and superior chemical resistance.

Cubic boron nitride is the second-hardest known material on the planet (after diamonds), but has higher heat and impact resistance than diamonds, and therefore CBN is preferred over diamond in industrial applications.
