Tru-maxx 51031870M Square Polishing Stone 150 Grit 6 in

Product Description

The TRU-MAXX 51031870M is a square aluminum oxide polishing stone designed for precision deburring, honing, and surface finishing of metal workpieces. Measuring 6 inches in overall length with a 1-inch by 1-inch cross section, this oil-filled stone delivers consistent stock removal and a refined surface finish at 150 grit, rated Very Fine. Machinists, tool-and-die makers, and maintenance technicians use this type of stone to remove burrs, smooth mating surfaces, and prepare components for close-tolerance assembly. The aluminum oxide abrasive is well suited for ferrous metals and hard alloys.

This polishing stone is a shop staple for metal fabrication, mold and die work, and general precision machining environments. The square profile allows flat surface contact on workpiece edges, bores, and flat stock. The oil-filled construction keeps the abrasive cutting cleanly and extends stone life during extended hand-honing operations. It is appropriate for use in both production shops and maintenance-repair settings where consistent surface quality is required.

Key Features

• 150 grit aluminum oxide abrasive rated Very Fine for smooth, controlled material removal
• Square profile provides full flat-face contact on edges, flats, and recesses
• Oil-filled construction reduces loading and extends usable stone life
• 6-inch overall length gives adequate working surface for hand honing
• 1-inch by 1-inch cross section for easy grip and consistent pressure application

Compatibility

Designed as a general-purpose hand honing stone suitable for deburring and surface finishing of ferrous metals, tool steels, and hard alloys in machining and fabrication applications.

Installation Notes

Hand honing stones are used by machinists and toolmakers without power tools in most applications. Apply honing oil or a light machine oil to the stone surface before use to prevent loading and improve cutting action. Work the stone in consistent, controlled strokes along the workpiece surface and inspect frequently to avoid removing more material than intended. Clean the stone with solvent after use to extend its service life.
