Silicon carbide finishing stones vary from aluminium oxide finishing stones in that the particle shape of the grain is thinner and sharper than aluminium oxide particles.

Silicon carbide particles shave a narrow cut in the material being polished and produce a less brilliant finish because the narrow cut does not reflect as much light.

Silicon carbide tends to shape easily to contours and is typically fast cutting and breaks down quickly.

This polishing stone can be used to polish even the hardest die and mould steels.

Polishers claim excellent results with the CS-HD when finishing dies ranging in hardness from 47 to 63Rc.

 This stone should be used with a lubricant.


Inside the kit, you will find 5 abrasive stones and the proper lubricant required for these types of stones.
