Norton 61463643218 Rectangle Polishing Stone 150 Grit

Product Description

The NORTON 61463643218 is a rectangle-shaped polishing stone made from aluminum oxide abrasive. It is designed for fine surface finishing, deburring, and honing operations on metal, plastic, and other hard materials. At 8 inches in overall length and rated at 150 grit, this stone falls in the very fine grade category, making it well suited for final-stage smoothing where surface finish quality matters. Machinists, tool-and-die workers, and maintenance technicians reach for this type of stone when removing tool marks or blending surfaces after machining.

This polishing stone is used across a range of precision finishing applications in machine shops, fabrication environments, and maintenance facilities. It is appropriate for hand stoning flat surfaces, edges, and contours on tooling, dies, molds, and machined components. The rectangular profile provides a stable contact surface for consistent finishing strokes. It is sold individually and is suitable for bench use or hand-held finishing work.

Key Features

• Aluminum oxide abrasive construction for consistent cutting action on ferrous and non-ferrous metals
• 150 grit rating delivers very fine surface finishing suitable for final-stage work
• 8-inch overall length provides adequate working surface for flat and edge finishing tasks
• Rectangular shape ensures stable, flat contact during hand-stoning operations
• Lightweight at 0.063 pounds, suitable for extended hand use

Compatibility

Designed as a general-purpose hand polishing and honing stone for use in machine shop, tooling, and maintenance applications where a very fine aluminum oxide abrasive is required.

Installation Notes

This polishing stone is used by hand or in a fixture during bench finishing operations. Secure the workpiece before stoning to prevent movement and ensure a consistent finish. Use an appropriate honing oil or dry as required by the workpiece material. Inspect the stone surface periodically for loading or glazing and dress as needed to maintain cutting efficiency.
