Norton 61463643220 Rectangle Polishing Stone 150 Grit 8in

Product Description

The NORTON 61463643220 is a rectangle-shaped polishing stone made from aluminum oxide abrasive. It measures 8 inches in overall length and is rated at 150 grit, placing it in the very fine grade category. Aluminum oxide stones are a standard choice for finishing and deburring metal, plastic, and composite surfaces. This stone is suited for hand lapping, edge honing, and surface polishing tasks where consistent material removal and a smooth finish are required. Trade machinists, toolmakers, and maintenance technicians reach for this type of stone during final finishing stages on precision components.

This polishing stone is used in light industrial, manufacturing, and maintenance environments where hand stoning of flat or slightly contoured surfaces is part of the workflow. Its rectangular shape allows controlled strokes on flat faces, edges, and mating surfaces. At 150 grit very fine, it is appropriate for removing fine tool marks, blending surfaces, or preparing a workpiece for inspection or assembly.

Key Features

• Aluminum oxide abrasive construction for consistent cutting action on metal and hard materials
• 150 grit very fine grade for finish polishing and light stock removal
• Rectangle shape allows precise control on flat surfaces and edges
• 8 inches overall length provides adequate working surface for hand stoning tasks
• Suitable for deburring, lapping, and surface finishing applications

Compatibility

Designed as a general-purpose hand polishing stone for use on ferrous and non-ferrous metals, plastics, and composites in machining and maintenance applications.

Installation Notes

This stone is a hand-held abrasive tool and does not require mechanical installation. Secure the workpiece before stoning to prevent movement during use. Apply a light honing oil or cutting fluid to extend stone life and improve surface finish quality. Inspect the stone for cracks or uneven wear before each use.
