Norton 66253246861 Surface Grinding Wheel 60 Grit 8in

Product Description

The NORTON 66253246861 is a Type 1 vitrified aluminum oxide surface grinding wheel engineered for ferrous and non-ferrous stock removal across a range of industrial grinding applications. At 8 inches in diameter and 1/2 inch thick with a 1-1/4 inch arbor hole, this wheel carries a 60-grit, medium-grade abrasive with a K hardness code. The vitrified bond provides consistent cut rate and thermal resistance under sustained grinding loads. Maximum operating speed is rated at 3600 RPM. Specification code 60K8V32A identifies the full wheel formulation for documentation and replacement ordering. Weight is 3.73 pounds.

This wheel is suited for surface grinding and cylindrical grinding operations on tool steels, hard and soft carbon steels, 400 series stainless steel, aluminum, cast iron, ductile iron, and gray iron. Compatible machine types include surface grinders and CNC cutting tool machines. The 32A Series Type 1 construction offers a straight, flat profile with no recess and no taper, making it a standard fit for horizontal-spindle surface grinder setups in both production and tool-room environments.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or toolroom technician following ANSI B11.9 and OSHA 29 CFR 1910.215 standards. Before mounting, inspect the wheel for cracks or chips using the ring test. Power down and lock out the grinder before installing or changing wheels. Never exceed the 3600 RPM maximum speed rating stamped or labeled on the wheel.
