TOOLS FOR GRINDING, BUFFING OR SHARPENING (abrading-bodies specially designed for tumbling apparatus, e.g. abrading-balls B24B31/14; honing tools B24B33/08; lapping tools B24B37/11)

Introduced: September 1968

Description

B24D covers abrasive tools and grinding wheels designed for material removal, surface finishing, and edge preparation operations. This subclass encompasses rotating wheels, stones, and mounted abrasives used in grinding machines, as well as honing and sharpening tools for cutlery and industrial implements. Included are various abrasive compositions, grain types, and bonding materials that affect tool performance and durability. Related grinding machine designs and their operational mechanisms are classified separately under B24B.
