Value Collection 4256203 Rectangle Polishing Stone 220 Grit

Product Description

The VALUE COLLECTION 4256203 is a rectangle-shaped aluminum oxide polishing stone designed for fine honing, deburring, and surface finishing of metal and other hard materials. Measuring 6 inches in overall length, 0.5 inches wide, and 0.125 inches thick, this stone offers a slim profile suited for reaching tight tolerances and narrow slots. At 220 grit, it falls in the very fine category, making it appropriate for final-pass finishing work where a smooth, consistent surface is required. Machinists, tool-and-die workers, and precision trade professionals commonly use stones of this type for edge refinement and flatwork. It is not oil-filled.

This polishing stone is used in precision metalworking and fabrication environments where fine surface finishing is required. Its rectangular cross-section and 6-inch length make it well-suited for honing flat surfaces, cleaning up keyways, and finishing small-diameter bores or slots. The very fine 220 grit is appropriate for light material removal and final polishing passes rather than aggressive stock removal. Plumbers and pipefitters may also use comparable stones for valve seat finishing and port cleanup. This stone is sold individually but packaged in quantities of 12.

Key Features

• Aluminum oxide abrasive material for consistent cut and long service life on ferrous and non-ferrous metals
• 220 grit, very fine grade for finish honing and final-pass surface work
• Slim rectangular profile at 0.5 inches wide and 0.125 inches thick for access to tight or narrow features
• 6-inch overall length provides adequate reach and leverage for hand honing
• Not oil-filled, allowing use with a variety of honing fluids or dry depending on application

Compatibility

Designed as a general-purpose replacement or supplemental honing stone for use in hand lapping, deburring, and surface finishing operations on metal components across machining, fabrication, and trade service applications.

Installation Notes

Polishing stones of this type are installed and used by hand or in a bench-mounted holder without power tooling. Always secure the workpiece before applying the stone to avoid injury or marring. Use an appropriate honing fluid if the application requires lubrication to extend stone life and improve surface finish. Inspect the stone for cracks or irregular wear before each use and replace if the stone is no longer flat or shows signs of breakdown.
