Value Collection 4150622 Square Polishing Stone 220 Grit

Product Description

The VALUE COLLECTION 4150622 is a square-profile aluminum oxide polishing stone designed for fine finishing and deburring work on metal, ceramic, and composite surfaces. At 220 grit with a Very Fine grade designation, this stone removes light tool marks, smooths sharp edges, and refines surface finish without aggressive material removal. The stone measures 5/32 inches wide by 5/32 inches thick with a 4-inch overall length, making it well-suited for detail work in tight slots, keyways, and narrow recesses. It is not oil-filled. Machinists, tool-and-die technicians, and precision metalworkers are the primary users of this type of hand stone.

This polishing stone is used in precision finishing applications where a controlled, fine-grit abrasive is needed. Its square cross-section makes it effective for working flat surfaces, right-angle corners, and confined areas that larger or round stones cannot reach. Typical use cases include die polishing, mold finishing, tool sharpening touch-up, and edge conditioning on machined components. The 4-inch length provides adequate working leverage for hand-held strokes in bench or in-situ applications.

Key Features

• Square profile at 5/32 inches wide and 5/32 inches thick for access to slots, keyways, and recesses

Compatibility

Designed as a general-purpose hand polishing stone for bench and in-situ finishing applications across metalworking, toolmaking, and precision machining environments.

Installation Notes

Hand polishing stones require no power tools or installation. Secure the workpiece firmly before applying the stone to avoid movement during finishing strokes. Apply a compatible honing oil or use dry depending on the material and desired finish. Inspect the stone for chips or uneven wear before use to ensure consistent surface contact.
