The VALUE COLLECTION 4256404 is a rectangular aluminum oxide polishing stone designed for fine surface finishing and deburring of metal, ceramic, and hard plastic components. Measuring 6 inches in overall length, 0.5 inches wide, and 0.25 inches thick, this stone delivers controlled material removal at a 400-grit super fine grade. It is not oil-filled, making it ready for dry use or with a compatible honing fluid. Machinists, toolmakers, and trade professionals reach for this stone when dressing edges, smoothing mating surfaces, or removing light burrs left from machining or fabrication operations.
This polishing stone is suited for bench work and hand-lapping applications in machine shops, maintenance environments, and light fabrication settings. Its slim profile — 0.5 inches wide and 0.25 inches thick — allows access to narrow slots, keyways, and tight-tolerance surfaces where larger stones cannot reach. The 6-inch length provides a comfortable grip for controlled strokes. It is a common choice for final finishing passes where surface quality matters more than stock removal rate.
Designed as a general-purpose hand polishing stone for bench finishing, deburring, and surface conditioning tasks on metal, ceramic, and hard plastic workpieces.
This stone is a hand-held finishing tool requiring no power tools or special mounting. Secure the workpiece firmly in a vise or on a stable bench surface before use. Apply light, consistent pressure with even strokes; uneven pressure can round edges or create surface irregularities. If used with honing oil, apply sparingly and wipe the stone clean after each session to prevent loading.
