Norton 61463643629 Square Polishing Stone 900 Grit 6 in

Product Description

The NORTON 61463643629 is a square aluminum oxide polishing stone designed for fine surface finishing work. At 900 grit, it falls in the super fine grade range, making it well suited for the final stages of honing, deburring, and surface preparation on metal, plastic, or composite workpieces. Measuring 6 inches in overall length, the square profile provides consistent edge contact across flat surfaces and slots. Machinists, toolmakers, die finishers, and precision fabricators use this type of stone to remove light tooling marks and achieve smooth, refined surface finishes without aggressive material removal.

This polishing stone is used in precision metalworking environments, toolrooms, and maintenance shops where surface finish quality is critical. It is appropriate for hand lapping, edge honing, and cleanup work on molds, dies, and machined components. The square geometry allows access to inside corners and flat faces that rounded or tapered stones cannot reach as cleanly. Both production shops and job shops keep super fine stones like this on hand for finishing operations that follow coarser abrasive stages.

Key Features

• 900 grit super fine grade for final-stage polishing and light material removal
• Square profile reaches inside corners, slots, and flat surfaces cleanly
• Aluminum oxide abrasive provides consistent cutting action on ferrous and non-ferrous metals
• 6 inches overall length offers sufficient working surface for hand finishing operations
• Lightweight at 0.002 pounds for easy single-hand control during fine work

Compatibility

Designed as an OEM-style replacement or direct-use abrasive stone for hand finishing applications in precision metalworking, toolroom, and die maintenance operations.

Installation Notes

Polishing stones of this type are used by machinists and tool and die technicians as a hand tool — no power equipment is required. Always ensure the workpiece is secure before applying the stone to prevent movement that can cause surface scratching or personal injury. Light honing oil or water-based cutting fluid is commonly used with aluminum oxide stones to flush swarf and extend stone life. Inspect the stone for chips or uneven wear before use to maintain consistent surface contact.
