Tru-maxx 05118435M Silicon Carbide Polishing Stone 320 Grit

Product Description

The TRU-MAXX 05118435M is a rectangle-shaped polishing stone made from silicon carbide abrasive material. It measures 6 inches in overall length and delivers an extra fine 320 grit finish, making it suitable for deburring, honing, and surface polishing on metal, ceramic, and similar hard materials. This stone is not oil-filled, so it can be used dry or with a light water or oil application depending on the task. Machinists, toolmakers, and maintenance technicians reach for this type of stone when a controlled, consistent finish is required on tight-tolerance surfaces.

This polishing stone is used in machine shop environments, maintenance and repair operations, and light fabrication settings. It is appropriate for finishing valve seats, lapping flat surfaces, removing burrs from machined parts, and refining edges on tooling. The extra fine 320 grit designation makes it best suited for final-stage polishing rather than aggressive material removal. It is a single-unit item with no minimum order beyond one piece.

Key Features

• Silicon carbide construction for consistent cut on hard metals and ceramics
• 320 grit extra fine grade for finish polishing and light deburring
• 6-inch overall length for solid hand control and reach into confined areas
• Rectangle profile provides flat bearing surface for uniform stock removal
• Not oil-filled — compatible with dry use or user-applied lubricant

Compatibility

Designed as a general-purpose hand polishing stone for use on metal, ceramic, and hard plastic surfaces in machining, maintenance, and toolroom applications.

Installation Notes

This stone is a hand-held abrasive tool used by machinists and maintenance technicians. Secure the workpiece before use to prevent movement during polishing. When using with a lubricant, apply a light, even coat of honing oil or water to the stone surface to reduce loading and extend stone life. Inspect the stone surface regularly for glazing and dress as needed to maintain cutting performance.
