CBN is an abbreviation for Cubic Boron Nitride. It is an abrasive material. Cubic boron nitride is the second-hardest known material after diamond, making it useful in a wide variety of industrial applications.

Application: CBN wheels can be used on a bench grinder or on a woodworking lathe.

CBN wheels are suitable for all woodworking tools made of High Speed Steel (HSS).

The wheel consists of a metal body which is coated in a plating process with a layer of CBN grain. Plated wheels never change size or shape therefore eliminating time-consuming re-profiling.

Important: If you are used to using an aluminium oxide wheel, be aware that CBN wheels do not require much force, just a little backup pressure for the weight of the tool. Too much pressure can generate excessive heat and may harm the wheel. CBN grinding grains are as hard as diamond grains and will do the work for you without any effort and in a very short time.

Maintenance: None. The CBN wheel never needs truing or dressing.
