Tru-maxx 51033603M Silicon Carbide Polishing Stone 320 Grit

Product Description

The TRU-MAXX 51033603M is a rectangle polishing stone manufactured from silicon carbide abrasive, designed for fine surface finishing and deburring work on metal, ceramic, and composite materials. At 320 grit, this stone falls in the extra fine range, making it well suited for final-stage material removal, edge refinement, and surface prep before inspection or assembly. The stone measures 6 inches in overall length and is not oil-filled, so it can be used dry or with a light honing fluid depending on the application. Machinists, tool-and-die workers, and maintenance technicians reach for this type of stone when a controlled, consistent finish is required.

This polishing stone is used across a range of industrial and maintenance applications including sharpening cutting tools, smoothing valve seats, removing burrs from machined parts, and refining mating surfaces. Its rectangular profile provides flat, stable contact with workpiece surfaces. Typical install scenarios include machine shop benches, field maintenance kits, and pipe and valve service environments where precise surface finishing is part of the workflow.

Key Features

• Silicon carbide abrasive construction for consistent cutting action on hard materials
• 320 grit extra fine grade suited for final finishing and light deburring
• Rectangular profile delivers flat, even contact across workpiece surfaces
• 6-inch overall length provides good hand control during manual honing
• Non-oil-filled design allows dry use or use with a shop-applied honing oil

Compatibility

Designed as a general-purpose rectangle polishing stone for manual honing and surface finishing tasks on metal, ceramic, and similar hard materials.

Installation Notes

No power tools or special installation is required for hand honing stones. Secure the workpiece firmly before use and apply consistent, even pressure during strokes to avoid uneven wear on the stone face. When using with a honing fluid, select a fluid appropriate for the workpiece material. Inspect the stone surface periodically for glazing or uneven wear that could affect finishing quality.
