A silicon carbide based composition containing no aluminum oxide. Combines a medium cutting action with long life. Recommended for parts having no oxide impregnation, especially where parts are welded, brazed or soldered. Produces a clean finish on all parts. Bulk weight is 90 to 95 pounds per cubic foot.

CS-46
A fast cutting composition that is silicon carbide based. Contains no aluminum oxide. Recommended for parts having no oxide impregnation, especially where parts are welded, brazed or soldered. Gives parts a matte finish. Bulk weight is 90 to 95 pounds per cubic foot.

SJ
Available in spherical shapes only. An aggressive cutting action. Good for general to heavy deburring, producing short time cycles. Bulk weight is 95 to 100 pounds per cubic foot.
