Tru-maxx 05118419M Silicon Carbide Polishing Stone 150 Grit

Product Description

The TRU-MAXX 05118419M is a rectangle-shaped polishing stone made from silicon carbide abrasive material. It measures 6 inches in overall length and is rated at 150 grit, placing it in the Very Fine grade category. This bench stone is used to deburr, hone, and polish metal edges, cutting tools, and precision components. It is not oil-filled, meaning 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, fine surface finish is required on hardened steel or non-ferrous metal parts.

This polishing stone fits into general metalworking, machining, and tool maintenance workflows. It is suited for finishing work on flat or slightly contoured surfaces where a fine grit is needed to remove minor scratches, tool marks, or burrs left from grinding or machining operations. The silicon carbide grain is well matched to non-ferrous metals, cast iron, and carbide tooling. It is appropriate for use in machine shops, maintenance facilities, and toolrooms where hand-finishing and edge preparation are routine tasks.

Key Features

• Silicon carbide abrasive construction for fast cutting on non-ferrous metals and carbide
• 150 grit, Very Fine grade for controlled material removal and smooth surface finishing
• Rectangle shape provides flat, consistent contact surface for honing and deburring
• 6-inch overall length offers a full working surface for hand-held or bench use
• Not oil-filled — compatible with dry use or a user-applied honing oil

Compatibility

Designed as a general-purpose hand polishing and honing stone suitable for use on hardened steel, non-ferrous metals, cast iron, and carbide tooling in metalworking and maintenance applications.

Installation Notes

This polishing stone is a hand-held or bench-mounted tool and does not require mechanical installation. Secure the workpiece or clamp it in a vise before working the stone across the surface to maintain consistent angle and pressure. When using with honing oil, apply a light, even coat to the stone face before use to float away swarf and extend stone life. Keep the stone clean and free of metal buildup between uses to maintain consistent cutting performance.
