Norton 61463687795 Silicon Carbide Roughing Stone 20 Grit

Product Description

The NORTON 61463687795 is a rectangular silicon carbide roughing stone rated at 20 grit, placing it in the very coarse grade category. It is designed for aggressive stock removal on metal, stone, and other hard materials where rapid surface conditioning is the priority. Measuring 3.5 inches wide by 8 inches long by 1.5 inches thick, the stone provides a stable, full-hand grip and a large working face suited for flat surface work. Silicon carbide is a hard, fast-cutting abrasive mineral well suited to materials such as cast iron, non-ferrous metals, ceramics, and masonry. Machinists, toolroom technicians, and maintenance trades use this stone to remove burrs, scale, and rough machining marks before moving to finer finishing steps.

This roughing stone is used in metalworking shops, maintenance and repair operations, and fabrication environments where coarse surface preparation is needed. The rectangular profile suits flat lapping, edge dressing, and general deburring on workpieces that require significant material removal. The 8-inch length accommodates longer contact strokes across larger workpiece surfaces, making it practical for bench work and on-machine applications. It is sold individually with a minimum order quantity of one unit.

Key Features

Compatibility

Designed as a general-purpose coarse abrasive stone for bench and hand use in metalworking, maintenance, and fabrication applications where very coarse stock removal is required.

Installation Notes

This stone is a hand-held or bench-mounted abrasive tool and does not require mechanical installation. Secure the workpiece or the stone firmly before use to prevent slipping. Wear appropriate eye protection and gloves when using coarse abrasive stones. Inspect the stone for cracks or chips before each use and replace if structural integrity is compromised.
