Tru-maxx 05091533M Silicon Carbide Polishing Stone 320 Grit

Product Description

The TRU-MAXX 05091533M is a rectangle-profile polishing stone made from silicon carbide abrasive, intended for precision deburring, lapping, and surface finishing of metal and non-metal workpieces. At 320 grit, this stone falls in the extra fine category, making it well suited for final-stage smoothing, edge cleanup, and light stock removal where surface quality matters. The stone measures 6 inches in overall length and weighs 1 pound. It is not oil-filled, so it can be used dry or with a compatible honing fluid applied by the technician. Machinists, toolmakers, and maintenance technicians are the primary users of this type of hand stone.

This polishing stone is used in industrial maintenance, machine shop, and manufacturing environments where hand-finishing of tooling, dies, molds, and precision components is required. The rectangular shape provides flat contact across the work surface, which is useful for dressing sharp edges, removing burrs from drilled or milled features, and blending surfaces prior to final inspection. Its compact 6-inch length makes it easy to maneuver in tight clearances or on small workpieces. Suitable for bench use or field maintenance applications.

Key Features

• Silicon carbide abrasive material provides consistent cutting action on hardened metals and non-ferrous materials
• 320 grit extra fine grade for final-stage polishing and surface blending
• 6-inch overall length in a rectangular profile for flat, controlled contact
• Not oil-filled — use dry or apply honing oil as needed for the application
• Lightweight at 1 pound for easy single-hand use during bench or field work

Compatibility

Designed as a general-purpose hand finishing stone suitable for use on metals, ceramics, and plastics requiring extra fine surface refinement in machine shop and industrial maintenance settings.

Installation Notes

No installation is required for hand polishing stones. Secure the workpiece firmly in a vise or fixture before applying the stone to prevent movement during finishing. If using a honing fluid, apply a thin, consistent layer to the stone face before contact to improve cutting action and reduce loading. Inspect the stone surface periodically for glazing or loading, and dress the stone on a flat lapping plate if cutting efficiency decreases.
