Tru-maxx 51033330M Square Polishing Stone 220 Grit

Product Description

The TRU-MAXX 51033330M is a square silicon carbide polishing stone designed for fine surface finishing and deburring work. At 220 grit, it falls in the very fine abrasive range, making it well suited for smoothing machined surfaces, removing light burrs, and polishing metal, ceramic, or composite workpieces to a refined finish. The stone measures 4 inches in overall length with a 1-inch by 1-inch cross section. Silicon carbide construction provides sharp, fast-cutting abrasive action and holds up well against hard materials. This stone is not oil-filled, so it can be used dry or with a cutting fluid depending on the application and material being worked.

This polishing stone is used in machine shops, fabrication environments, and maintenance settings where controlled hand-finishing is required. It is appropriate for machinists, tool-and-die technicians, millwrights, and maintenance professionals who need precise surface conditioning on metal parts, molds, dies, or tooling components. The square profile allows flat-face contact on flat surfaces and fits into grooves or slots that round or cylindrical stones cannot reach.

Key Features

• 220 grit very fine abrasive for final-stage finishing and light burr removal
• Silicon carbide construction cuts quickly on hard metals, ceramics, and composites
• Square profile provides flat-face contact and access to slots and grooves
• 4-inch overall length with 1-inch by 1-inch cross section for hand-held control
• Not oil-filled — compatible with dry use or water-based and oil-based cutting fluids

Compatibility

Designed as a general-purpose hand polishing stone for use on metal, ceramic, and composite surfaces in machining, tooling, and maintenance applications.

Installation Notes

This stone is a hand-held abrasive tool, not a mechanically mounted component. Use appropriate eye protection and gloves when performing grinding or polishing operations. Apply light, consistent pressure and use a suitable cutting fluid if working on hardened steel or heat-sensitive materials to extend stone life and improve surface finish. Inspect the stone for cracks or chips before each use and discard if structural integrity is compromised.
