Tru-maxx 01555523M Rectangle Polishing Stone 150 Grit

Product Description

The TRU-MAXX 01555523M is a rectangle aluminum oxide polishing stone designed for fine surface finishing work on metal, tooling, and precision components. Running at 150 grit, this stone falls in the very fine range, making it well suited for deburring edges, smoothing machined surfaces, and removing light tool marks before final finishing. The stone measures 8 inches in overall length with a 1-inch height and 1-inch width profile, providing a solid grip and consistent contact area. It is not oil-filled, so users have the option to apply their own honing oil or use it dry depending on the application. Machinists, tool-and-die workers, and maintenance technicians will find this a reliable bench tool.

This polishing stone is used in shop environments where hand-finishing and surface prep are part of routine workflow. Common applications include smoothing burrs on machined steel parts, conditioning mold surfaces, cleaning up weld areas, and preparing metal surfaces before inspection or assembly. It is equally at home in a production machine shop or a maintenance repair operation. The rectangular profile allows controlled strokes across flat surfaces, slots, and broad contours without the need for specialized holders.

Key Features

• 150 grit aluminum oxide abrasive for very fine finishing and deburring
• Rectangle profile supports flat-surface strokes and controlled hand work
• 8-inch overall length provides extended reach and stable handling
• 1-inch by 1-inch cross-section for consistent contact and grip

Compatibility

Designed as a general-purpose hand polishing stone suitable for use on ferrous metals, tool steel, and similar hard surfaces requiring fine abrasive finishing.

Installation Notes

This stone is a hand-held abrasive tool used by machinists and metalworkers; no power tools or special mounting are required. Secure the workpiece firmly before applying strokes to avoid uneven material removal. If using honing oil, apply a light coat to the stone surface before work to reduce loading and extend stone life. Inspect the stone for cracks or uneven wear before each use.
