Norton 66252938887 Surface Grinding Wheel 46 Grit 7in

Product Description

The NORTON 66252938887 is a Type 5 surface grinding wheel engineered for aggressive stock removal on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent coarse-grade cutting action at up to 3600 RPM. It measures 7 inches in diameter and 1 inch thick, with a 1-1/4 inch arbor hole and a one-sided recess 2-3/4 inches in diameter and 1/2 inch deep. The 32AA46-IVTR specification indicates a medium-hardness, porous structure suited for wet grinding operations. Machinists and tool grinders rely on this wheel for flat surface and peripheral work on a surface or cylindrical grinder.

This wheel is rated for wet operation and is appropriate for production and maintenance grinding across a wide range of materials. Listed material applications include 400 Series Stainless, Hard Carbon Steels, Soft Carbon Steels, Tool Steels, Aluminum, Cast Iron, Ductile Iron, and Gray Iron. The Type 5 recessed profile is specifically designed for use with surface grinders and cylindrical grinders where clearance and balance are critical to finish quality and wheel longevity.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or tool grinder familiar with ANSI B11.9 and OSHA 29 CFR 1910.215 wheel safety standards. Always inspect the wheel for cracks or chips before mounting and perform a ring test when applicable. Power down and lock out the grinder before changing wheels. Never exceed the maximum RPM marked on the wheel blotter.
