CS-M SILICON CARBIDE GENERAL PURPOSE POLISHING STONE
General Purpose Polishing Stone · Green Silicon Carbide · Medium-Soft Structure with Moderate Breakdown
CS-M is a premium green silicon carbide finishing stone with superb cutting capabilities. A special bond makes the CS-M non-loading with a medium soft hardness for excellent polishing. It produces a silky matte finish on all pre-hardened tool steels, from 28Rc SAE 4130 through 60Rc A2 and M2. CS-M is the most popular stone used on H-13 and can be used to rough out beryllium, copper and kirksite. It is a good choice for stoning contours and radii as it contours nicely to the tool. It can be used either by hand with one of our Hand Holders or with reciprocating profilers like our U-Lap and Turbo-Lap Air Profilers. Can be used with or without a lubricant.

Available in 120-1200 grit and a wide variety of sizes including round shapes.
Also available in regular and fine grit kits.
Silicon carbide finishing stones vary from aluminum oxide finishing stones in that the particle shape of the grain is thinner and sharper than aluminum 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.
