Norton 66252841940 Type 27 Grinding Wheel 4.5in 36 Grit

Product Description

The NORTON 66252841940 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal surfaces. Built with aluminum oxide abrasive and a resinoid bond, this wheel delivers consistent stock removal across a range of ferrous metals. At 4.5 inches in diameter with a 3/32 inch thickness, it mounts on a standard 7/8 inch arbor and fits common 4.5 inch angle grinders. The 36-grit, medium-grade construction makes it well suited for weld blending, surface grinding, and edge work where fast cutting action is the priority.

This wheel is used in fabrication shops, construction sites, and maintenance environments where angle grinders are the primary tool. The Type 27 raised-hub profile positions the wheel at a low working angle, reducing user fatigue during extended surface grinding. It is commonly installed by metal fabricators, pipefitters, ironworkers, and general tradespeople performing weld cleanup, deburring, and surface prep on structural steel, plate, and pipe.

Installation Notes

Installation should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels. Always inspect the wheel for cracks or damage before mounting and ensure the grinder guard is in place before operation. Confirm the grinder spindle speed rating meets or exceeds the wheel maximum RPM before use. Never exceed the rated operating speed marked on the wheel.
