Norton 66252842177 Type 27 Grinding Wheel 3in 24 Grit

Product Description

The NORTON 66252842177 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal and other hard surfaces. Built with a ceramic alumina abrasive and a coarse 24 grit rating, this wheel cuts fast and holds up under sustained pressure. The resinoid bond holds abrasive grains securely during high-speed operation, and the wheel is rated to 18,000 RPM. At 3 inches in diameter and 1/8 inch thick with a 3/8-inch arbor hole, it fits compact angle grinders used in tight work areas. Metalworkers, fabricators, and maintenance trades rely on this wheel for weld removal, surface prep, and edge grinding tasks.

This wheel is suited for use in metal fabrication shops, maintenance and repair operations, and field service environments. The 3-inch format is a common fit for smaller angle grinders used in confined spaces such as pipe joints, corners, and structural steel connections. The coarse 24 grit rating makes it best applied to stock removal and rough grinding rather than finishing work. It is a single-piece packaged unit appropriate for individual task use or restocking a tool kit.

Installation Notes

Installation and wheel changes should be performed by qualified personnel following ANSI B7.1 safe use standards for abrasive wheels. Always power down and disconnect the grinder from its power source before mounting or removing the wheel. Inspect the wheel for cracks or chips before each use and never exceed the rated maximum RPM. Ensure the arbor nut is tightened securely using the proper spanner wrench before operating.
