Norton 66261058769 Unitized Deburring Wheel 3 in Density 4

Product Description

The NORTON 66261058769 is an aluminum oxide unitized deburring wheel rated for up to 8,000 RPM. It is designed to remove burrs, smooth sharp edges, and blend surface irregularities on metal workpieces. The wheel measures 3 inches in diameter with a 3/4-inch face width and a 1/4-inch center hole. Built with a Density 4, fine-grade abrasive construction, it delivers consistent, controlled material removal without aggressive stock loss. Machinists, fabricators, and tool room technicians install this wheel when a repeatable, light-finishing abrasive action is required across a range of power tools.

This unitized wheel is suited for deburring and edge-blending applications on metal parts in both production and maintenance environments. The 1/4-inch arbor hole and compact 3-inch diameter make it compatible with a wide range of handheld and bench-mounted grinders. It is appropriate for use on ferrous and non-ferrous metals where edge quality and surface finish are critical to part acceptance or downstream assembly.

Installation Notes

Installation should be performed by a qualified machinist or tool operator following the grinder manufacturer's mounting instructions. Always power down and disconnect or lock out the grinder before mounting or removing the wheel. Verify that the grinder's rated speed meets or does not exceed the wheel's 8,000 RPM maximum before operation. Inspect the wheel for cracks or damage prior to each use and do not operate a damaged wheel.
