SureWerx 500241 JET 7 x 7/8 C16 POWERFLEX Semi Flexible Disc

Specially designed for grinding and finishing concrete, stone, hard building materials and fiberglass. Made from extremely sharp silicon carbide grains for fast cutting and long wheel life. Manufactured by attaching multiple layers of silicone carbide to a semi-flexible fibre backing. Spiral grooves in the abrasive coating provides quick clearing of ground-off stock. Multiple cooling holes reduce the build-up of heat during grinding operations, greatly extending the life of the disc
