Norton 61463643225 Polishing Stone 8 in 180 Grit

Product Description

The NORTON 61463643225 is a rectangular aluminum oxide polishing stone designed for precision surface finishing and deburring work. Aluminum oxide is a hard, durable abrasive that cuts consistently across a wide range of metals, ceramics, and hard plastics. At 180 grit, this stone falls in the very fine range, making it suited for final-stage honing, light stock removal, and smoothing machined or ground surfaces. At 8 inches in overall length, it provides sufficient working surface for hand-applied finishing passes on flat or slightly contoured workpieces. Machinists, tool-and-die workers, and maintenance technicians commonly reach for this type of stone during bench work and tooling prep.

This polishing stone is used in metalworking shops, maintenance and repair environments, and light manufacturing settings where controlled hand finishing is required. It is appropriate for deburring edges on ferrous and non-ferrous metals, cleaning up mating surfaces, and preparing tooling for assembly. The rectangular profile provides flat, consistent contact against flat workpiece surfaces, making it a standard choice for bench stone applications where predictable abrasive geometry matters.

Key Features

• 180 grit aluminum oxide abrasive for very fine, controlled material removal
• Rectangular profile delivers consistent flat contact on machined surfaces
• 8-inch overall length provides ample working area for bench stone use
• Suited for final-stage honing, deburring, and surface prep on metals and hard materials
• Single-piece packaging ready for individual bench or field use

Compatibility

Designed as an OEM-style replacement or direct-use polishing stone for standard bench stone applications in metalworking, maintenance, and toolroom environments where a rectangular aluminum oxide stone is specified.

Installation Notes

This stone is applied by hand or in a fixture during bench finishing operations. Secure the workpiece firmly before applying the stone to avoid inconsistent surface contact. A light honing oil or water-based lubricant is commonly used to float swarf away from the abrasive surface and extend stone life. Inspect the stone face periodically for glazing and dress or replace as needed to maintain cutting efficiency.
