Value Collection 890-6315 Polishing Stone Kit 20 Piece

Product Description

The VALUE COLLECTION 890-6315 is a 20-piece polishing stone kit combining aluminum oxide and silicon carbide abrasives in a range of grit grades including Very Fine, Extra Fine, and Super Fine. These rectangular polishing stones are used to refine and finish metal, plastic, and composite surfaces by removing tooling marks, burrs, and surface imperfections. Machinists, tool-and-die workers, and precision fabricators rely on this type of kit for hand-stoning operations on molds, dies, and machined components. The graduated grit selection allows the user to progress from coarser finishing work down to a polished, smooth surface using a single kit.

This kit is suited for bench and hand-stoning applications in machine shops, maintenance facilities, and fabrication environments. The rectangular stone shape provides flat contact on machined surfaces, making it practical for deburring edges, blending parting lines on molds, and finishing bearing surfaces. The inclusion of multiple grit grades in one package reduces the need to source individual stones separately, which is useful for shops that perform a wide range of surface finishing tasks.

Installation Notes

Polishing stones are installed by hand or in a stone holder and require no power tools for basic hand-stoning operations. Work on a stable surface and secure the workpiece before applying the stone. Use appropriate cutting fluid or honing oil to extend stone life and improve surface finish quality. Inspect stones for cracks or uneven wear before each use and replace any damaged stones to avoid inconsistent results.
