Tru-maxx 01556133M Silicon Carbide Polishing Stone 180 Grit

Product Description

The TRU-MAXX 01556133M is a rectangle-shaped polishing stone made from silicon carbide abrasive material. It measures 6 inches in overall length and is rated at 180 grit, which falls in the very fine grade range. This bench stone is used for honing, deburring, and finishing metal edges, cutting tools, and precision parts. It is not oil-filled, making it suitable for use dry or with a light honing fluid depending on the application. Machinists, toolmakers, pipefitters, and maintenance technicians reach for this type of stone when a controlled, fine surface finish is required on ferrous and non-ferrous workpieces.

This polishing stone is a practical choice for light stock removal and surface refinement in machine shops, fabrication environments, and general maintenance settings. Its rectangular profile allows flat, consistent contact on straight edges, flat faces, and tool bevels. The silicon carbide composition cuts efficiently on harder materials including cast iron, carbide tooling, and non-ferrous metals such as aluminum and brass. It is well suited for bench use or hand-held finishing work where grit consistency and a repeatable finish are priorities.

Key Features

• Silicon carbide abrasive construction for efficient cutting on hard and non-ferrous materials
• 180 grit very fine grade for controlled surface finishing and light deburring
• Rectangle profile provides flat, even contact on straight edges and flat workpiece faces
• Not oil-filled — compatible with dry use or user-applied honing fluid
• 6 inch overall length for comfortable bench and hand-held use

Compatibility

Designed as a general-purpose bench polishing stone for use on metal surfaces, cutting tool edges, and precision components requiring a very fine 180 grit finish.

Installation Notes

No power tools or mechanical installation required. Secure the workpiece in a vise or on a stable bench surface before use. Apply a compatible honing oil or use dry depending on the material and desired finish. Inspect the stone surface periodically for glazing or loading, and dress with a lapping plate or coarser stone as needed to maintain cutting performance.
