Grier Abrasives ST-4-C-21330 Finishing Stick 4 in Medium

Product Description

The GRIER ABRASIVES ST-4-C-21330 is a round silicone carbide finishing stick designed for precision deburring, honing, and surface finishing of hard materials. It measures 4 inches in total length with a 1/2 inch working width and features a 3/32 inch diameter shank that extends 1-1/2 inches for secure tool or hand holding. The vitrified bond construction provides consistent abrasive exposure throughout the life of the stick. At 0.076 pounds, it is lightweight enough for extended hand use or use in a rotary tool setup. Medium grade grit suits general-purpose stock removal and finishing work on metal, ceramic, and similar hard surfaces.

This finishing stick is suited for trade and industrial applications where controlled material removal is needed in tight areas, ports, bores, or along contoured edges. Machinists, tool and die makers, HVAC technicians dressing valve seats, plumbers cleaning fitting seating surfaces, and general fabricators use finishing sticks like this for detail work that grinding wheels and sandpaper cannot reach. The round profile makes it effective in curved grooves, radius cuts, and cylindrical bores.

Installation Notes

This finishing stick is used by hand or mounted in a compatible rotary tool or die grinder. Always wear appropriate eye protection and gloves when using abrasive sticks on hard materials. Inspect the stick for cracks or chips before each use and do not apply excessive lateral pressure, which can cause breakage. Operate within the speed rating of any power tool used with this accessory.
