Norton 66252839430 Type 27 Grinding Wheel 7in 24 Grit

Product Description

The NORTON 66252839430 is a Type 27 depressed center grinding wheel designed for aggressive material removal on metal and fabricated components. Built with a ceramic alumina abrasive and a resinoid bond, this wheel delivers consistent cutting action across a wide range of ferrous and non-ferrous applications. At 24 grit coarse grade, it removes stock quickly and is suited for grinding welds, beveling edges, and smoothing rough cuts. The 7/8 inch arbor hole mounts to standard 7-inch angle grinders, and the wheel is rated to a maximum of 8,600 RPM. At 0.348 pounds, it is lightweight enough for extended overhead or vertical grinding work.

This wheel is a common choice for metal fabrication shops, structural steel work, and field welding operations. The Type 27 depressed center profile keeps the grinding face at the correct angle to the workpiece, reducing fatigue and improving control during flat and surface grinding passes. It is installed and used by ironworkers, welders, pipefitters, and general metal fabricators in both shop and field environments. The coarse 24-grit ceramic alumina abrasive is well suited for initial weld grinding and heavy stock removal before finishing operations.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety per ANSI B7.1 standards. Always inspect the wheel for cracks or damage before mounting and never exceed the rated maximum RPM of the grinder or the wheel. Power down and disconnect the grinder from its power source before changing wheels, and confirm the arbor flange and backing flange are clean and correctly seated before tightening. Eye protection and appropriate PPE are required during use.
