Tru-maxx 51033660M Silicon Carbide Polishing Stone 150 Grit

Product Description

The TRU-MAXX 51033660M is a rectangle polishing stone made from silicon carbide abrasive, designed for fine surface finishing, deburring, and honing work. At 150 grit, it falls in the very fine range, making it well suited for refining edges, smoothing machined surfaces, and achieving consistent finish quality on metal, ceramic, and other hard materials. The stone measures 6 inches in overall length and weighs 1 pound. It is not oil-filled, so it can be used dry or with an appropriate honing fluid depending on the application. Machinists, toolmakers, pipefitters, and maintenance technicians commonly keep this type of stone on hand for precision hand-finishing tasks.

This polishing stone is used in metalworking, maintenance, and fabrication environments where controlled hand-finishing is required. Typical applications include removing burrs from machined edges, smoothing valve seats or sealing surfaces, lapping flat mating surfaces, and preparing parts for final assembly. The rectangular profile allows the user to work flat faces, corners, and edges without rolling or rounding unintended areas. It is a standard bench and field finishing tool across machine shops, plant maintenance operations, and trade service work.

Key Features

• Silicon carbide abrasive for fast cutting action on hard materials
• 150 grit very fine grade for controlled surface refinement and deburring
• 6-inch overall length provides good hand control and coverage
• Rectangular profile suits flat surfaces, edges, and inside corners
• Not oil-filled — compatible with dry use or user-applied honing fluid

Compatibility

Designed as a general-purpose hand finishing stone suitable for use on metal, ceramic, carbide, and similar hard materials in bench or field applications.

Installation Notes

No power tools or mechanical mounting are required — this stone is used by hand or on a bench fixture. Secure the workpiece before applying the stone to avoid movement during finishing. When working on precision mating surfaces, keep strokes consistent and check flatness frequently with a straightedge or surface plate. Wear appropriate eye and hand protection when deburring sharp edges.
