Norton 66261055374 Convolute Deburring Wheel 12 Inch

Product Description

The NORTON 66261055374 is a convolute deburring wheel designed for aggressive material removal and surface conditioning on metal workpieces. Built with silicon carbide abrasive at a density of 9 and a hard density grade, this wheel delivers consistent cut on ferrous and non-ferrous metals. It measures 12 inches in diameter with a 2-inch face width and a 5-inch center hole, spinning safely at a maximum rated speed of 2,500 RPM. Metal fabricators, machinists, and maintenance technicians use this wheel to remove burrs, sharp edges, and light surface scale left after cutting, stamping, or grinding operations.

This deburring wheel is suited for use on bench grinders and pedestal grinders in production shops, job shops, and maintenance facilities. The convolute construction winds abrasive material in layers around the core, providing a consistent abrasive surface throughout the life of the wheel. Silicon carbide abrasive makes it well-matched for harder non-ferrous materials including aluminum, brass, titanium, and carbide, as well as cast iron. It is sold individually and is a direct replacement when a worn convolute wheel of matching dimensions needs to be swapped out.

Installation Notes

Installation should be performed by a qualified machinist or maintenance technician following the grinder manufacturer's mounting instructions. Disconnect and lock out electrical power to the grinder before mounting or removing any wheel. Inspect the wheel for cracks or damage before installation and never exceed the 2,500 RPM maximum rated speed marked on the wheel. Ensure flanges and blotters are correctly seated and the arbor nut is tightened to the manufacturer's specification before operating.
