Value Collection 25800 Rectangle Polishing Stone 320 Grit

Product Description

The VALUE COLLECTION 25800 is a rectangular aluminum oxide polishing stone designed for fine finishing and surface refinement work. At 6 inches in overall length, this extra fine 320-grit stone removes light scratches, burrs, and machining marks from metal, ceramic, and similar hard surfaces. Aluminum oxide construction provides consistent cutting action and durability across repeated use cycles. The blue-gray color is standard for this grit and material combination, making it easy to identify at a glance in a tool kit. Machinists, toolmakers, die finishers, and maintenance technicians keep stones like this on hand for deburring, edge work, and final-stage surface prep before assembly or inspection.

This polishing stone suits bench work and hand-finishing applications in machine shops, tool and die operations, and general metalworking environments. It is well suited for honing flat surfaces, removing light tool marks, and smoothing edges on ferrous and non-ferrous metals. The 320-grit extra fine classification makes it appropriate for finishing passes rather than aggressive stock removal. It can also be used on plastics and ceramics where controlled abrasion is needed. The 6-inch length provides enough working surface for most bench-finishing tasks without requiring a vise or fixture for control.

Key Features

• Aluminum oxide abrasive for consistent, controlled cutting action on hard surfaces
• 320 grit extra fine classification suited for final finishing and light deburring
• 6-inch overall length provides a comfortable working surface for hand use
• Rectangular profile allows flat-surface honing and edge work
• Blue-gray color for quick grit identification in a mixed-stone kit

Compatibility

Designed as a general-purpose hand polishing stone for bench-finishing applications on metal, ceramic, and plastic surfaces where extra fine abrasion is required.

Installation Notes

Polishing stones of this type are used by hand or in a fixture for controlled surface finishing work. Secure the workpiece in a vise when honing edges or flat surfaces to maintain consistent contact and avoid uneven wear on the stone. Use a light honing oil or water to extend stone life and improve swarf clearance during use. Inspect the stone surface periodically and dress it flat if glazing or uneven wear develops.
