Value Collection 4256204 Rectangle Polishing Stone 220 Grit

Product Description

The VALUE COLLECTION 4256204 is a rectangular aluminum oxide polishing stone designed for precision deburring, honing, and surface finishing on metal, plastic, and composite workpieces. At 220 grit, this stone falls in the very fine category, making it well suited for final-pass finishing work where smooth surface contact and tight tolerances matter. Measuring 6 inches in overall length, 0.5 inches wide, and 0.25 inches thick, the narrow profile allows access to slots, keyways, and other confined geometry that wider stones cannot reach. Machinists, tool-and-die workers, and maintenance technicians commonly keep stones like this on hand for bench and field finishing tasks.

This polishing stone is intended for hand-lapping and bench stone applications across general metalworking, toolroom, and light manufacturing environments. The aluminum oxide abrasive cuts consistently on hardened and unhardened ferrous metals as well as many non-ferrous materials. The rectangular form factor suits flat surfaces, inside corners, and edge work. No oil fill is present in this stone, so it can be used dry or with a light honing oil depending on the application and desired surface finish result.

Key Features

• 220 grit very fine aluminum oxide abrasive for final-pass finishing and light deburring
• Narrow 0.5-inch by 0.25-inch cross section for access to slots, keyways, and tight geometry
• 6-inch overall length provides sufficient contact area for controlled hand strokes
• Non-oil-filled construction allows dry use or use with honing oil
• Rectangular profile suits flat surfaces, inside corners, and edge cleanup

Compatibility

Designed as a general-purpose hand polishing and honing stone suitable for metalworking, toolroom, and maintenance applications requiring very fine grit surface finishing.

Installation Notes

This stone is a hand-held abrasive tool and does not require mechanical installation. Secure the workpiece firmly before applying the stone to avoid inconsistent contact or surface damage. When using with a honing oil, apply a light coat to the stone face and keep strokes consistent in pressure and direction. Inspect the stone face periodically for glazing and dress or replace as needed to maintain cutting performance.
