Value Collection 4256212 Rectangle Polishing Stone 220 Grit

Product Description

The VALUE COLLECTION 4256212 is a rectangle polishing stone made from aluminum oxide abrasive, designed for fine surface finishing and deburring work on metal, ceramic, and composite materials. Measuring 6 inches in overall length, 1 inch wide, and 0.25 inch thick, this stone delivers a 220-grit, very fine cutting action suited for final smoothing passes, edge refinement, and precision surface prep. It is not oil-filled, making it compatible with a range of honing fluids or dry use depending on the application. Machinists, toolmakers, and maintenance technicians reach for this type of stone when a controlled, consistent finish is required on close-tolerance work.

This polishing stone is appropriate for bench work, hand lapping, mold and die finishing, and general shop maintenance tasks. Its compact rectangular profile fits easily into tight areas, keyways, slots, and flat surfaces where larger abrasive tools cannot reach. The very fine 220-grit rating makes it best suited for finish work rather than aggressive stock removal. It is commonly used in machine shops, fabrication facilities, and maintenance environments where surface quality and edge condition are critical to part function.

Key Features

• Aluminum oxide abrasive construction for consistent cutting on ferrous and non-ferrous metals
• 220 grit, very fine grade for finish polishing and light deburring
• Compact 6 inch x 1 inch x 0.25 inch profile fits confined areas and tight tolerances
• Not oil-filled, allowing use with preferred honing oil or dry as needed
• Rectangle shape provides flat, stable contact for bench and hand-held use

Compatibility

Designed as a general-purpose hand polishing stone suitable for use on metal, ceramic, and composite surfaces requiring fine abrasive finishing.

Installation Notes

This stone is a hand-applied abrasive tool and does not require power-tool mounting or mechanical installation. Apply light, consistent pressure during use and keep the stone flat against the workpiece surface to avoid uneven wear. When using a honing fluid, apply it to the stone surface before starting to extend stone life and improve cutting action. Inspect the stone for cracks or uneven wear before each use and replace if the surface is no longer flat.
