Norton 66253431487 16 in Zirconia Alumina Cut-off Wheel

Product Description

The NORTON 66253431487 is a reinforced zirconia alumina cut-off wheel engineered for high-demand metal cutting applications on stationary grinders. Measuring 16 inches in diameter and 5/32 inches thick with a 1 inch arbor hole, this Type 1 (01/41) wheel is bonded with a resinoid bond and rated to a maximum of 3820 RPM. The zirconia alumina abrasive delivers a fast, free-cutting action suited to ferrous metals, making it a dependable choice for fabricators and maintenance techs who need consistent performance on production-level stationary grinding equipment. Both sides are reinforced for added structural integrity during cutting operations.

This cut-off wheel is designed for use with stationary grinders in industrial and fabrication environments. The NZ Foundry Free Cut specification indicates it is suited for cutting steel and stainless steel without contaminating the workpiece surface — a critical requirement when working with stainless. Typical applications include structural steel fabrication, pipe cutting, and foundry work where a large-diameter, high-capacity wheel is required. Licensed fabricators, ironworkers, and maintenance mechanics are the primary installers and operators of this wheel.

Compatibility

Designed for use with stationary grinders. Rated for cutting steel and stainless steel. Verify that the grinder spindle speed does not exceed 3820 RPM before mounting this wheel.

Installation Notes

Installation and wheel changes must be performed by qualified personnel following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before mounting or removing a wheel. Inspect the wheel for cracks or damage before each use and perform a ring test as required. Never exceed the maximum rated RPM of 3820; confirm the machine nameplate RPM before operation.
