Tru-maxx 01555275M Square Polishing Stone 220 Grit 6 in

Product Description

The TRU-MAXX 01555275M is a square aluminum oxide polishing stone designed for precision surface finishing and deburring applications. Measuring 6 inches in overall length with a 1-inch square cross-section, this stone delivers consistent material removal at 220 grit, placing it in the very fine grade category. Aluminum oxide construction provides reliable cutting action on hardened tool steels, molds, and general metalworking components. This stone is not oil-filled, making it ready for use with a cutting fluid of the technician's choice or dry depending on the application. It is a standard hand-finishing tool used by machinists, toolmakers, and maintenance technicians in both shop and field settings.

This polishing stone suits precision metalworking environments where surface finish quality is critical. Typical applications include deburring machined parts, honing flat surfaces, cleaning up mold cavities, and refining tool edges. The very fine 220 grit is appropriate for finishing passes rather than aggressive stock removal. It is commonly used in machine shops, tool-and-die operations, and maintenance departments working on tight-tolerance components. The square profile allows access to flat faces, shoulders, and right-angle features that round or tapered stones cannot reach effectively.

Key Features

• 220 grit aluminum oxide abrasive for very fine surface finishing
• Square profile provides access to flat surfaces, shoulders, and inside corners
• 6-inch overall length offers sufficient reach for most hand-finishing tasks
• 1-inch square cross-section for stable grip and consistent contact area
• Not oil-filled, compatible with user-selected cutting fluid or dry use

Compatibility

Designed as a general-purpose hand polishing stone suitable for use on hardened steels, tool steels, and other ferrous and non-ferrous metals in standard machining and maintenance applications.

Installation Notes

Polishing stones are hand-applied tools and do not require mechanical installation. Secure the workpiece firmly before use to prevent movement during finishing. When using a cutting fluid, apply it consistently to the stone face to extend abrasive life and improve surface finish results. Keep the stone flat against the work surface to avoid uneven wear and maintain a consistent finish across the part.
