Value Collection 4256183 Rectangle Polishing Stone 180 Grit

Product Description

The VALUE COLLECTION 4256183 is a rectangular aluminum oxide polishing stone designed for fine-finishing and deburring work on metal, ceramic, and hard plastic surfaces. Measuring 6 inches in overall length, 0.5 inches wide, and 0.125 inches thick, this stone delivers controlled material removal at a 180 grit very fine grade. Its slim profile makes it well-suited for working in slots, keyways, and tight recesses where larger stones cannot reach. Machinists, tool-and-die workers, and maintenance technicians typically reach for this stone when a part needs a refined surface finish before final inspection or assembly.

This polishing stone is used in precision metalworking environments including machine shops, toolrooms, and general maintenance settings. The rectangular cross-section provides flat, consistent contact across the work surface, making it effective for lapping flat faces, smoothing burrs on stamped parts, and refining edges on hardened tooling. It is not oil-filled, so users apply honing oil or a light lubricant separately during use to float swarf and extend stone life. Sold in packages of 12, it suits bench stock for shops that go through stones regularly.

Key Features

• 180 grit very fine aluminum oxide abrasive for refined surface finishing and light deburring

• Packaged in quantities of 12, suitable for bench stock replenishment in production or maintenance shops

Compatibility

Designed as a general-purpose rectangular polishing stone suitable for hand-finishing operations on metal, ceramic, and hard plastic workpieces in toolroom and maintenance applications.

Installation Notes

Used by hand or with a simple holder in toolroom, machining, and maintenance applications — no power tools required for standard polishing and deburring use. Apply a light coat of honing oil or equivalent lubricant to the stone surface before use to prevent loading and extend abrasive life. Keep the stone flat against the work surface to avoid rounding edges unintentionally. Store stones dry and protected from impact to prevent chipping.
