Norton 61463643630 Rectangle Polishing Stone 900 Grit

Product Description

The NORTON 61463643630 is a rectangle-shaped aluminum oxide polishing stone used for fine surface finishing and deburring work. At 900 grit, it falls in the super fine category, making it suited for the final stages of hand honing, edge refinement, and surface preparation on metal, tooling, and precision components. Weighing just 0.003 pounds, this is a compact, lightweight stone intended for close-tolerance hand work. Machinists, tool and die technicians, and maintenance tradespeople typically keep stones like this on hand for touch-up work on cutting edges, mating surfaces, and burr removal after machining or grinding operations.

This polishing stone is designed for bench and hand use in machine shops, maintenance facilities, and fabrication environments. At 6 inches in overall length, it provides enough working surface for most hand-honing tasks. The aluminum oxide abrasive is a general-purpose material well suited for ferrous metals, tool steels, and hardened surfaces. It is commonly used in applications where a smooth, consistent surface finish is required before assembly or final inspection.

Key Features

• 900 grit super fine grade for final-stage honing and polishing
• Aluminum oxide abrasive material suitable for ferrous metals and tool steels
• Rectangle shape for flat surface contact and controlled hand strokes
• 6-inch overall length provides adequate working area for most hand-honing tasks
• Lightweight at 0.003 pounds for easy handling and precise control

Compatibility

Designed as a general-purpose hand polishing stone for use on metal surfaces, cutting tools, and precision components where super fine surface finishing is required.

Installation Notes

This stone is a hand-applied abrasive tool and does not require mechanical installation. Use with a compatible honing oil or light cutting fluid to extend stone life and prevent loading of the abrasive surface. Apply consistent, even pressure during use to avoid uneven wear. Inspect the stone surface periodically for glazing or loading and dress as needed to maintain cutting performance.
