Value Collection 8906270 Square Polishing Stone 600 Grit

Product Description

The VALUE COLLECTION 8906270 is a square aluminum oxide polishing stone designed for precision deburring, honing, and surface finishing of metal parts and tooling. Measuring 0.125 inches wide by 0.125 inches thick and 4 inches in overall length, this slender profile fits into tight spaces where broader stones cannot reach. At 600 grit, it falls in the super fine range, making it suited for final-stage finishing passes that require a smooth, consistent surface. Machinists, tool-and-die workers, and maintenance technicians use stones like this to refine edges, remove fine burrs, and blend surfaces on precision components.

This polishing stone is commonly used on manual and CNC machine components, dies, molds, punches, and metal fixtures. Its small square cross-section is particularly useful for accessing slots, keyways, and recessed features. The aluminum oxide abrasive is a general-purpose material appropriate for ferrous and non-ferrous metals. This stone is sold without oil fill, so a light application of honing oil is recommended when wet-stone finishing is preferred.

Key Features

• 600 grit super fine aluminum oxide abrasive for final-stage finishing and polishing
• Square profile at 0.125 inches wide and 0.125 inches thick allows access to narrow slots and recesses
• 4 inch overall length provides adequate grip and control during hand finishing
• Non-oil-filled construction allows use dry or with separately applied honing oil
• Sold in packages of 12, suitable for shop stock and regular replacement cycles

Compatibility

Designed as an OEM-style replacement or shop-supply polishing stone for use in precision metalworking, tool-and-die, and general maintenance finishing applications.

Installation Notes

Polishing stones of this type are used by hand or in stone holders; no power tools are required. Secure the workpiece in a vise or fixture before applying the stone to maintain consistent pressure and avoid uneven material removal. When wet finishing, apply honing oil directly to the stone or workpiece surface before use. Inspect the stone periodically for uneven wear and replace when the abrasive surface no longer cuts consistently.
