Tru-maxx 51033124M Silicon Carbide Polishing Stone 320 Grit

Product Description

The TRU-MAXX 51033124M is a rectangle polishing stone made from silicon carbide abrasive, designed for finishing, deburring, and surface preparation work on metal and other hard materials. At 320 grit, it falls in the extra fine range, making it suited for final-stage honing, light material removal, and smoothing machined surfaces. 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 a compatible honing fluid depending on the application. Machinists, tool and die workers, and maintenance technicians typically keep stones like this on hand for precision bench work.

This polishing stone is used in machine shops, maintenance facilities, and fabrication environments where surface finish quality matters. Extra fine 320 grit is appropriate for removing fine scratches, polishing valve seats or mating surfaces, and achieving a smooth finish on steel, cast iron, and similar materials. The rectangular profile allows controlled flat-surface contact and edge work. It is a standard bench stone format used across industrial and trade settings.

Key Features

• Silicon carbide abrasive construction for consistent cutting action on hard materials
• 320 grit extra fine grade for finishing and final-stage surface smoothing
• 6-inch overall length provides stable hand control during bench work
• Rectangular profile allows flat-surface polishing and edge honing
• Not oil-filled, compatible with dry use or applied honing fluid

Compatibility

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

Installation Notes

Secure the workpiece or stone firmly before use to prevent slipping. When using with a honing fluid, apply the fluid evenly across the stone face before beginning. Maintain consistent angle and pressure during strokes to avoid uneven wear on the stone surface. No power tools or special codes apply to hand-stone use, but standard shop safety practices including eye protection should be followed.
