Norton 61463643321 Rectangle Polishing Stone 120 Grit 8in

Product Description

The NORTON 61463643321 is a rectangle polishing stone made from aluminum oxide abrasive. It is used to deburr, smooth, and refine metal surfaces, edges, and bores to a fine finish. At 8 inches in overall length and rated at 120 grit Fine grade, this stone removes light tool marks and produces a consistent, polished surface on ferrous and non-ferrous metals. Machinists, tool-and-die workers, and maintenance technicians keep this style of stone on hand for bench work and in-place component finishing. The aluminum oxide construction delivers reliable cutting action and consistent wear across the stone face.

This polishing stone is suited to precision metal finishing in machine shops, fabrication facilities, and maintenance environments. Common applications include smoothing mold surfaces, cleaning up machined bores, and refining sharp edges on tooling and fixtures. It is also used by HVAC and plumbing tradespeople for deburring copper tubing ends and metal fittings prior to assembly. The compact rectangle form allows controlled hand pressure across flat and slightly curved work surfaces.

Key Features

• Aluminum oxide abrasive for reliable stock removal on ferrous and non-ferrous metals
• 120 grit Fine grade for light material removal and surface refinement
• 8 inch overall length provides adequate contact area for bench and field use
• Rectangle profile allows flat, controlled contact on machined surfaces and edges
• Lightweight at 0.065 pounds for easy single-hand operation

Compatibility

Designed as a general-purpose hand polishing stone for use on machined metal components, tooling, and fixtures where a Fine 120 grit finish is required.

Installation Notes

No power tools or mounting hardware are required for hand-stoning applications. Keep the work surface and stone clean and free of debris to maintain consistent grit contact. Apply light, even pressure and use a honing oil or lubricant appropriate for the base material to extend stone life and improve surface finish. Inspect the stone for cracking or uneven wear before each use and replace if the surface is no longer flat.
