Norton 61463643628 Rectangle Polishing Stone 900 Grit

Product Description

The NORTON 61463643628 is a rectangle-shaped polishing stone made from aluminum oxide abrasive, designed for fine surface finishing and honing work. At 900 grit, it falls into the super fine grade category, making it suitable for the final stages of sharpening or polishing metal, ceramic, or composite surfaces. The aluminum oxide bond delivers consistent cutting action and long service life under repeated use. Machinists, tool-and-die technicians, HVAC fabricators, and precision tradespeople use stones in this grit range to refine valve seats, tool edges, and mating surfaces before final assembly or inspection.

This stone is used in applications where a clean, smooth surface finish is required before parts go into service. Common install scenarios include deburring machined components, lapping valve seats, polishing burrs from cut pipe ends, or preparing mating flanges for gasket seating. Its rectangular form factor fits standard stone holders and can be used freehand on flat or contoured work surfaces. It is suited for both bench use and field service work.

Compatibility

Designed as an OEM-style replacement or direct-use polishing stone for applications requiring a super fine aluminum oxide abrasive in a standard rectangular form factor.

Installation Notes

Polishing stones in this grit range are typically used by machinists, pipefitters, and HVAC technicians during surface prep and finishing steps. Always secure the workpiece before applying the stone to avoid slippage and uneven wear. Use a honing oil or light lubricant where the application requires to prevent glazing of the stone surface. Dispose of worn or fractured stones per shop safety procedures.
