Value Collection 8906268 Square Polishing Stone 320 Grit

Product Description

The VALUE COLLECTION 8906268 is a square aluminum oxide polishing stone designed for fine honing and finishing work on metal, ceramic, and composite surfaces. Measuring 0.125 inches wide by 0.125 inches thick with a 4-inch overall length, this slender profile allows access to tight grooves, slots, and recessed features that larger stones cannot reach. At 320 grit, it falls in the extra fine range, making it suited for removing light burrs, refining edges, and producing a smooth surface finish after rougher stock removal has been completed. Machinists, tool and die technicians, and precision fabricators typically keep stones in this size and grit on hand for bench work and detail finishing.

This polishing stone is well suited for deburring precision machined parts, cleaning up mold cavities, and finishing internal keyways or narrow slots in tooling components. Its square cross-section maintains a consistent contact geometry on flat and angular surfaces. The 4-inch length provides enough handle length for controlled hand strokes. It is sold in packages of 12, making it a practical shop stock item for facilities that consume honing stones regularly during production or maintenance operations.

Key Features

• Aluminum oxide abrasive construction for consistent stock removal on ferrous and non-ferrous materials
• 320 grit extra fine grade for final finishing and light deburring passes
• Square profile at 0.125 inches wide and 0.125 inches thick for access to narrow slots and recessed features
• 4-inch overall length provides adequate hand clearance for controlled strokes
• Not oil-filled, compatible with dry use or supplemental honing oil as preferred
• Packaged in quantities of 12 for bench stock replenishment

Compatibility

Designed as a general-purpose bench polishing stone suitable for use on hardened steel, tool steel, aluminum, and similar materials in machining, fabrication, and maintenance applications.

Installation Notes

Polishing stones are applied by hand or with a holder; secure the workpiece firmly before honing to maintain consistent pressure and stroke angle. Apply a light honing oil or mineral oil to extend stone life and improve swarf clearance, unless operating conditions require dry use. Inspect the stone for cracks or chips before each use and discard any stone that shows structural damage. No power tools or special codes apply to hand honing operations, but standard shop PPE including eye protection and cut-resistant gloves is recommended.
