Norton 66253363761 Surface Grinding Wheel 60 Grit 14 in

Product Description

The NORTON 66253363761 is a Type 1 surface grinding wheel designed for high-stock-removal operations on ferrous and non-ferrous metals. Built with aluminum oxide abrasive and a vitrified bond, this wheel delivers consistent cut rate and form retention across extended run cycles. At 14 inches in diameter and 1/2 inch thick with a 5-inch arbor hole, it is sized for industrial surface grinders and cylindrical grinders running at up to 1800 RPM. The 60 grit, K hardness (medium grade) specification suits general-purpose stock removal where a balance of cut rate and surface finish is required. Weight is 6.3 pounds.

This wheel is rated for use on 400 series stainless steel, hard and soft carbon steels, tool steels, aluminum, cast iron, ductile iron, and gray iron. It is intended for production and maintenance grinding on CNC cutting tool machines, cylindrical grinders, and surface grinders in commercial shops and industrial facilities. Licensed grinding wheel technicians and tool-and-die professionals are the primary installers and operators. The porous, vitrified structure promotes coolant penetration and chip clearance during wet or dry grinding cycles.

Key Features

• Aluminum oxide abrasive for reliable stock removal on ferrous and non-ferrous materials
• Vitrified bond construction provides form stability and consistent wheel breakdown
• Porous structure improves coolant flow and reduces heat buildup at the workpiece
• 60 grit, K hardness (medium grade) balances aggressive cut rate with controlled surface finish
• No recess, no taper — straight Type 1 profile fits standard surface grinder spindle flanges
• Series designation 32A60-KVBE for direct cross-reference and replacement ordering

Compatibility

Rated for use with CNC cutting tool machines, cylindrical grinders, and surface grinders. 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 must be performed by a qualified operator following ANSI B11.9 and OSHA 29 CFR 1910.215 standards for abrasive wheel machinery. Always ring-test the wheel before mounting and inspect for cracks or chips. Power down and lock out the machine before removing or installing any grinding wheel. Never exceed the maximum rated speed of 1800 RPM under any operating condition.
