Tru-maxx 01556158M Rectangle Polishing Stone 220 Grit

Product Description

The TRU-MAXX 01556158M is a silicon carbide rectangle polishing stone designed for precision surface finishing and deburring work. At 220 grit, this stone falls in the very fine range, making it well suited for final-stage finishing passes where a smooth, refined surface is required. The stone measures 6 inches in overall length and weighs 1 pound. It is not oil-filled, so no pre-soaking or lubrication setup is required out of the package. Machinists, tool-and-die workers, maintenance technicians, and skilled tradespeople use stones like this to dress workpieces, remove light burrs, and refine mating surfaces on metal, ceramic, and composite materials.

This polishing stone fits into general-purpose hand finishing and bench work applications. It is commonly used in machine shops, maintenance facilities, and fabrication environments where close-tolerance surface prep is needed. The rectangular profile provides flat, consistent contact across a workpiece, which is important when finishing flat surfaces, slots, or edges. It is appropriate for both production and repair workflows where surface quality affects part fit or seal integrity.

Key Features

• Silicon carbide abrasive material for effective cutting action on hard metals and ceramics
• 220 grit very fine grade for final-stage finishing and light material removal
• Rectangular profile provides consistent flat contact for flat surfaces and edges
• 6-inch overall length allows good hand control and reach across workpieces
• Not oil-filled — ready to use dry or with a separately applied honing fluid

Compatibility

Designed as a general-purpose hand finishing stone suitable for use on metal, ceramic, and composite workpiece surfaces in bench and machine shop environments.

Installation Notes

This stone is a hand-held abrasive tool used by machinists and maintenance technicians — no power tools or trade licensing are required for typical use. Secure the workpiece before applying the stone to prevent movement during finishing passes. When using with honing oil or cutting fluid, apply the fluid directly to the stone or workpiece surface and keep the work area clear of excess fluid to avoid slip hazards. Inspect the stone before use for cracks or chips that could affect surface contact.
