Value Collection 8906204 Square Polishing Stone 150 Grit

Product Description

The VALUE COLLECTION 8906204 is a square aluminum oxide polishing stone designed for fine surface finishing and deburring work on metal, tooling, and precision components. Measuring 0.25 inches wide by 0.25 inches thick and 4 inches in overall length, this stone delivers controlled material removal at 150 grit, rated Very Fine. It is not oil-filled, making it suitable for dry use or with a light honing fluid. Machinists, tool-and-die technicians, and maintenance tradespeople reach for stones in this class when flat lapping, edge conditioning, or removing burrs from close-tolerance parts.

This polishing stone fits common hand-honing and benchwork applications across machine shops, fabrication environments, and maintenance departments. Its square profile allows access to slots, keyways, and flat surfaces where rounded or tapered stones cannot seat properly. The compact 4-inch length suits both bench vise work and handheld use in the field. Sold in a package quantity of 12, making it practical to stock in a tool crib or service kit.

Installation Notes

Polishing stones require no permanent installation but should be used with appropriate personal protective equipment including eye protection. Secure the workpiece firmly in a vise or fixture before applying the stone to prevent slipping. When using with a honing fluid or light oil, keep the work area clear of ignition sources if flammable fluids are involved. Inspect the stone for cracks or chips before each use and discard damaged stones immediately.
