Value Collection 8906219 Square Polishing Stone 400 Grit

Product Description

The VALUE COLLECTION 8906219 is a square aluminum oxide polishing stone designed for fine surface finishing, deburring, and honing work on metal, ceramic, and other hard materials. Measuring 0.25 inches wide by 0.25 inches thick and 4 inches in overall length, this stone delivers a 400-grit super-fine abrasive action suited for achieving smooth, refined surface finishes. It is not oil-filled, making it a dry-use stone appropriate for bench work or hand-held finishing operations. Machinists, tool-and-die makers, and maintenance technicians reach for this type of stone when precision surface prep or edge cleanup is the priority.

This polishing stone is well suited for precision finishing applications in machine shops, maintenance facilities, and fabrication environments. Its compact square profile fits into tight areas and narrow slots where larger stones cannot reach. The 400-grit super-fine grade makes it appropriate for final-pass work where surface quality matters, such as removing light burrs, smoothing tool edges, or preparing mating surfaces before assembly. It is sold in a package of 12 units, supporting shop-floor stock or multi-technician use.

Installation Notes

This stone is a hand-held abrasive tool and does not require mechanical installation. Keep the work surface and stone clean of debris during use to maintain consistent abrasive action. Apply only moderate hand pressure to avoid uneven wear or chipping the stone. Inspect the stone before each use and replace if cracked or unevenly worn.
