Grier Abrasives ST-4-GB-18315 Finishing Stick Coarse

Product Description

The GRIER ABRASIVES ST-4-GB-18315 is a square aluminum oxide finishing stick designed for precision deburring, honing, and surface finishing of metal components. It measures 4 inches long by 3/8 inches wide by 3/8 inches thick, with a 3/32-inch diameter shank that extends 1.5 inches for secure tool holding. The aluminum oxide abrasive grain is bonded with a vitrified bond, which provides consistent cutting action and shape retention during use. Coarse grade grit makes this stick well suited for aggressive stock removal and initial surface cleanup. Machinists, tool and die makers, and maintenance technicians keep this style of stick on hand for sharpening, cleaning mold cavities, and fitting close-tolerance parts.

This finishing stick is used in metalworking, machining, and fabrication environments where hand-held or spindle-mounted abrasive shaping is required. Common applications include deburring drilled holes, cleaning up parting lines in molds, dressing worn tooling surfaces, and smoothing weld seams in hard-to-reach areas. The square profile allows the technician to work into corners and slots that round or cylindrical sticks cannot reach. It is appropriate for bench work as well as light machine-mounted use when attached via its shank.

Key Features

• Square profile reaches corners and slots inaccessible to round abrasive tools
• Aluminum oxide grain delivers consistent cutting on ferrous and non-ferrous metals
• Vitrified bond maintains shape and provides open structure for cooler cutting

Compatibility

Designed as an OEM-style replacement finishing stick for use in standard rotary tool chucks and die grinder collets accepting a 3/32-inch shank diameter.

Installation Notes

Secure the shank firmly in the collet or chuck before operating any rotary tool or die grinder. Always wear appropriate eye protection and gloves when using abrasive sticks, as fragments and metal particles can be ejected during use. Inspect the stick for cracks or chips before each use and do not operate beyond the rated speed of the abrasive. Disconnect or de-energize any powered equipment before changing or installing abrasive accessories.
