Value Collection 8906229 Square Polishing Stone 800 Grit

Product Description

The VALUE COLLECTION 8906229 is a square-profile aluminum oxide polishing stone designed for fine finishing and deburring work on metal, ceramic, and composite surfaces. Measuring 0.25 inches wide by 0.25 inches thick and 4 inches in overall length, this stone runs at 800 grit, placing it in the super fine category. It is not oil-filled, making it ready to use dry or with a compatible honing fluid. Machinists, tool-and-die makers, and precision fabricators use stones in this profile and grit range to refine edges, remove minor burrs, and polish tight slots or keyways that larger abrasive tools cannot reach.

This polishing stone is suited to bench and hand-held sharpening or finishing tasks in machine shops, maintenance environments, and precision manufacturing settings. The square cross-section allows flat-face contact on internal slots, grooves, and flat surfaces alike. At 4 inches in length, it provides sufficient working surface for controlled strokes by hand or in a holder. Its super fine 800-grit rating makes it appropriate as a final finishing step following coarser stock removal.

Key Features

• 800 grit super fine abrasive for final-stage polishing and edge refinement
• Square profile provides flat-face contact in slots, keyways, and flat surfaces
• Aluminum oxide abrasive material suitable for ferrous and non-ferrous workpieces
• Not oil-filled — use dry or apply honing oil as required by the application
• Compact 0.25 x 0.25 x 4-inch form factor fits tight or confined workpiece features

Compatibility

Designed as a general-purpose hand polishing stone for bench finishing and precision deburring applications across metalworking, machining, and maintenance trades.

Installation Notes

Secure the workpiece firmly before applying the stone to avoid slipping and uneven material removal. Apply light, consistent pressure using smooth strokes along the surface being finished; excessive force can cause uneven wear or chipping of the stone. Keep the stone clean and free of metallic debris between uses to maintain consistent abrasive contact. No power tools or special codes apply to hand stone use, but appropriate eye protection and hand protection are recommended during deburring operations.
