Norton 66252843192 Type 27 Grinding Wheel 4.5in 24 Grit

Product Description

The NORTON 66252843192 is a Type 27 depressed center grinding wheel designed for aggressive material removal on angle grinders. Built with a zirconia alumina abrasive bond, this coarse 24-grit wheel cuts fast and handles demanding applications on steel, stainless steel, and other ferrous metals. The resinoid bond holds the abrasive grain firmly during high-speed operation, with a maximum rated speed of 13,580 RPM. At 4.5 inches in diameter and 0.25 inches thick with a 7/8 inch arbor hole, it mounts directly to standard angle grinders. Fabricators, pipefitters, ironworkers, and metal finishing contractors use this wheel for weld blending, deburring, and surface conditioning tasks.

This wheel is suited for both shop and field use wherever an angle grinder is the tool of choice. The Type 27 depressed center profile keeps the grinding face at a low angle relative to the workpiece, which improves operator control and reduces gouging on flat and contoured surfaces. It is a single-unit packaged item, making it a practical stocking choice for service trucks, fabrication shops, and maintenance departments that go through grinding wheels regularly.
