Norton 61463643217 Square Polishing Stone 150 Grit 8in

Product Description

The NORTON 61463643217 is a square aluminum oxide polishing stone designed for fine surface finishing and deburring work. At 8 inches in overall length and rated at 150 grit (Very Fine), it removes light surface material and refines finishes on metal, tooling, and precision machined parts. Aluminum oxide is a durable abrasive that holds up through repeated use on ferrous and non-ferrous materials. This stone is a standard hand tool for machinists, tool and die workers, and maintenance technicians who need controlled, consistent stock removal at a fine grit level.

This polishing stone is suited for bench work and hand lapping applications in machine shops, fabrication facilities, and maintenance environments. It handles edge cleanup, burr removal, and surface preparation on flat or slightly contoured workpiece faces. The square profile provides consistent contact across flat surfaces and allows edge work along corners. At 8 inches, it gives adequate stroke length for most hand finishing tasks without excessive bulk.

Key Features

• Aluminum oxide abrasive for durable, consistent cutting action on metal surfaces
• 150 grit Very Fine grade for light stock removal and smooth surface refinement
• Square profile maintains flat contact for uniform finishing on flat workpieces
• 8-inch overall length provides full-stroke reach for bench and hand lapping work
• Lightweight at 0.25 pounds for extended hand use without fatigue

Compatibility

Designed as a general-purpose hand polishing stone for fine finishing and deburring applications on metal, tooling, and precision components in machine shop and maintenance settings.

Installation Notes

Polishing stones are used by machinists and maintenance technicians as hand tools requiring no power or mounting. Apply light honing oil or water to the stone surface during use to float away swarf and prevent glazing. Inspect the stone face periodically for uneven wear and dress as needed to maintain a flat working surface. Store flat to prevent chipping or cracking of the abrasive body.
