Value Collection 4256403 Rectangle Polishing Stone 400 Grit

Product Description

The VALUE COLLECTION 4256403 is a rectangle polishing stone made from aluminum oxide abrasive, designed for fine surface finishing and deburring work on metal, ceramic, and similar hard materials. Measuring 6 inches in overall length, 0.5 inches wide, and 0.125 inches thick, this stone carries a 400-grit super fine grade that removes light tooling marks and refines surfaces to a smooth finish. It is not oil-filled, making it suitable for use dry or with a compatible honing fluid. Machinists, toolmakers, and maintenance technicians reach for this type of stone when dressing tooling edges, fitting mating surfaces, or polishing confined geometry where larger stones cannot reach.

This polishing stone is suited to light-duty precision finishing tasks in machine shops, tool rooms, and general maintenance environments. Its narrow profile and thin cross-section allow access to slots, keyways, and tight clearances that wider stones cannot address. The super fine 400-grit rating makes it appropriate for final-pass finishing rather than aggressive stock removal. Sold in a package quantity of 12, it is a practical stock item for shops that cycle through fine abrasives regularly.

Key Features

Compatibility

Designed as a general-purpose rectangle finishing stone suitable for hand-honing, bench work, and precision surface finishing applications across a range of hard materials.

Installation Notes

This stone is a hand-held abrasive tool and requires no installation. Keep the stone and workpiece clean of debris during use to maintain consistent cut rate and avoid surface scratching. When using a honing fluid, select one compatible with the workpiece material. Inspect the stone periodically for uneven wear and dress it on a flat lapping plate if flatness is critical to the application.
