Value Collection 4121154 Rectangle Polishing Stone 150 Grit

Product Description

The VALUE COLLECTION 4121154 is a rectangle polishing stone made from silicon carbide, designed for fine material finishing and edge work across a range of trade and shop applications. At 150 grit, this stone falls in the very fine range, making it well suited for the final stages of sharpening, deburring, and surface preparation on metal, ceramic, and composite materials. The stone measures 6 inches in overall length, 0.5 inches wide, and 0.25 inches thick, giving it a slim profile that fits into tight areas and along narrow edges. It is not oil filled and works dry or with a compatible honing fluid.

This polishing stone is used in maintenance, repair, and fabrication environments where controlled material removal and a fine surface finish are required. Typical applications include sharpening cutting tools, smoothing burrs from machined parts, dressing valve seats, and refining edges on blades or precision components. The slim rectangular form makes it practical for detail work in HVAC, plumbing, and general mechanical trade settings where larger stones cannot reach. It is sold individually but packaged in quantities of 12, making it a practical stock item for shop supply.

Compatibility

Designed as a general-purpose replacement or stock polishing stone for use in trade shop, maintenance, and light fabrication environments requiring a very fine silicon carbide abrasive in a slim rectangle form factor.

Installation Notes

Polishing stones are used by machinists, pipefitters, HVAC technicians, and general mechanical trades for hand sharpening and surface finishing. Always secure the workpiece before applying the stone, and use consistent, even pressure to avoid uneven wear. When used with a honing fluid, select a fluid compatible with the workpiece material. Inspect the stone for cracks or chips before each use and replace if the abrasive surface is unevenly worn.
