Tru-maxx 51033751M Silicon Carbide Polishing Stone 400 Grit

Product Description

The TRU-MAXX 51033751M is a rectangle-shaped polishing stone made from silicon carbide abrasive. It measures 6 inches in overall length and delivers a 400-grit, super fine finish suitable for deburring, honing, and surface conditioning of metal, ceramic, and composite workpieces. The stone is not oil-filled, making it ready to use dry or with a light cutting fluid as job conditions require. Machinists, toolmakers, and maintenance technicians reach for this stone when a consistent, fine surface finish is needed on tight-tolerance parts or hard materials where coarser abrasives would remove too much stock.

This polishing stone is suited for bench work and hand-lapping applications in machine shops, manufacturing facilities, and maintenance environments. At 400 grit super fine, it is typically used in finishing stages to refine surfaces left by coarser stones, remove light burrs, or polish edges on cutting tools and precision components. Its rectangular profile allows flat-face contact on flat surfaces and controlled edge work in slots or keyways.

Key Features

• Silicon carbide abrasive for effective cutting on hard metals, ceramics, and composites
• 400 grit super fine grade for finishing and light material removal
• 6-inch overall length provides good control and reach for hand-lapping tasks
• Rectangle profile maintains flat contact for consistent surface conditioning
• Not oil-filled — use dry or apply cutting fluid as needed for the application

Compatibility

Designed as a general-purpose hand polishing stone for bench and field use on metal, ceramic, and hard composite surfaces where a super fine abrasive finish is required.

Installation Notes

No power tools or special mounting hardware are required for hand-lapping applications. Secure the workpiece firmly before applying the stone to avoid inconsistent contact. When using a cutting fluid, apply sparingly and keep the stone surface clean to prevent glazing. Dispose of worn stones in accordance with local shop waste guidelines.
