Straight cartridge rolls are excellent for sanding and polishing channels, fillets, recesses, side walls, and bottoms of dead-end holes. Great for high-speed deburring and flash removal. The multi-layer roll will expose new sharp cutting abrasive as each layer wears away. Long-lasting performance and quick removal and installation means less downtime. Use with mandrel #95103. Also available in full taper design. Package of 100.
