Ceramic is said to be hard for the next diamond, using the zirconia as a material Difficult to heat generation compared to a metal bar, less wear of the blade there is a difficult characteristic entangled during cutting of soft material, you can use for a long time.
Because of the lightweight, also by increasing the number of revolutions has become difficult to runout.

It is suitable for polishing of hard alloys and the like, and there are many types of particle sizes and it is made slightly harder than silicon, so firm polishing is possible.
It also reduces rubber dropout than usual and has a long service life.
