Tru-maxx 01556174M Silicon Carbide Polishing Stone 220 Grit

Product Description

The TRU-MAXX 01556174M is a rectangle-shaped polishing stone made from silicon carbide abrasive material. It measures 6 inches in overall length and carries a 220 grit rating, placing it in the very fine grade category. This type of bench stone is used to hone, deburr, and refine edges on metal components, valve seats, fittings, and precision parts. It is not oil-filled, making it suitable for dry use or use with a compatible honing fluid. Machinists, pipefitters, plumbers, and HVAC technicians reach for stones like this when conditioning tools or smoothing sealing surfaces prior to assembly.

This polishing stone fits into general metalworking and trade service applications where surface finish quality matters. It is sized for benchtop or handheld use, making it practical for field service kits as well as shop settings. Common applications include smoothing burrs on copper or steel pipe fittings, refining valve components, and touch-up work on cutting tool edges. The compact 6-inch length makes it easy to handle in tight workspaces.

Key Features

• Silicon carbide construction for consistent cut rate on ferrous and non-ferrous metals
• 220 grit very fine grade for finish honing and light deburring
• 6-inch overall length suits both benchtop and handheld use
• Rectangle profile provides flat, stable contact surface
• Not oil-filled — compatible with dry use or applied honing fluid

Compatibility

Designed as a general-purpose rectangle polishing stone suitable for use on metal surfaces, valve seats, fittings, and tool edges across HVAC, plumbing, and general mechanical service applications.

Installation Notes

No power tools or fasteners are required for use. Apply light, consistent pressure when working across a surface to maintain an even finish and avoid uneven wear on the stone. Keep the work surface and stone clean of metal filings between passes. If using a honing fluid, select one compatible with silicon carbide abrasives.
