Value Collection 890-6311 Polishing Stone Kit 20 Piece

Product Description

The VALUE COLLECTION 890-6311 is a 20-piece polishing stone kit that combines aluminum oxide and silicon carbide abrasives in a range of grits — Very Fine, Extra Fine, and Super Fine. These rectangular-profile stones are used to refine, deburr, and polish metal surfaces to close tolerances. The kit provides multiple abrasive grades in a single package, allowing technicians and machinists to progress through finishing stages without sourcing separate stones. At 1 pound for the full set, the stones are lightweight and easy to handle during bench or field work.

This kit suits applications in metalworking, machining, and general fabrication where surface finish quality is critical. The range of grits makes it appropriate for work on tool steel, dies, molds, and precision components. Machinists, tool-and-die workers, and maintenance technicians commonly reach for this type of stone kit when hand-finishing machined surfaces, cleaning up burrs on metal parts, or preparing mating surfaces for assembly. The rectangular abrasive shape allows access to flat surfaces and edges.

Key Features

• 20 individual stones in a single kit covering Very Fine, Extra Fine, and Super Fine grit grades
• Dual abrasive material — aluminum oxide and silicon carbide — suited to a range of metals and surface conditions
• Rectangular abrasive shape for flat surface contact and edge work
• Lightweight kit at 1 pound total, suitable for bench use or portable toolbox storage
• Multiple grit stages in one package reduce the need for separate abrasive purchases

Compatibility

Designed for hand-polishing and finishing applications on metal surfaces across general machining and fabrication environments. No specific machine or equipment compatibility is required for use.

Installation Notes

Polishing stones are hand-applied tools and do not require power or mechanical installation. When working on precision components, secure the workpiece firmly before applying the stone to avoid slippage and unintended material removal. Use appropriate eye protection when working with abrasive stones, as fine grit particles and metal debris can become airborne. Progress through grit grades in sequence — coarser to finer — to achieve the desired surface finish without introducing new scratches.
