Norton 66253043417 Surface Grinding Wheel 8in 60 Grit

Product Description

The NORTON 66253043417 is a Type 1 straight surface grinding wheel designed for precision stock removal on ferrous and non-ferrous metals. It measures 8 inches in diameter, 1/4 inch thick, with a 1-1/4 inch arbor hole. The wheel is constructed with aluminum oxide abrasive bonded in a vitrified matrix, rated at J hardness (medium grade) with a 60 grit cut. The specification code is 32A60-JVBE. Rated to 3600 RPM maximum, it is suited for wet or dry operation. Machinists, tool grinders, and maintenance professionals install and dress this wheel during routine surface and cylindrical grinding operations.

This wheel is built for use on surface grinders, cylindrical grinders, and CNC cutting tool machines. It is rated for use on 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. The porous, vitrified bond structure promotes coolant flow and chip clearance, making it a practical choice for high-volume surface grinding work in shop and industrial environments. It ships individually and has a minimum order quantity of one.

• Type 1 straight wheel profile, no recess, no taper

Compatibility

Rated for use with surface grinders, cylindrical grinders, and CNC cutting tool machines. Compatible material applications include 400 series stainless steel, hard carbon steels, soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron.

Installation Notes

Grinding wheel mounting and dressing should be performed by a qualified machinist or toolroom technician following ANSI B7.1 safety standards. Always inspect the wheel for cracks or chips using the ring test before mounting, and never exceed the rated maximum RPM of 3600. Power down and lock out the grinder before changing wheels, and confirm arbor hole fit before securing the flanges. Use appropriate guards and eye protection during all grinding operations.
