Norton 66261058550 Convolute Deburring Wheel 6 in Aluminum Oxide

Product Description

The NORTON 66261058550 is a convolute deburring wheel designed for edge finishing, burr removal, and surface blending on metal workpieces. Built with aluminum oxide abrasive at a medium grade and Density 4, this wheel delivers controlled, consistent stock removal without excessive aggression. It measures 6 inches in diameter with a 1-inch face width and a 1-inch center hole, making it a straightforward fit on standard bench and pedestal grinders. Rated to a maximum of 4,500 RPM, it is suited for shop use by machinists, fabricators, and maintenance technicians working on ferrous and non-ferrous metal parts.

This convolute wheel is used in metal fabrication shops, machine shops, and industrial maintenance settings where clean, repeatable edge and surface finishing is required. The convolute construction layers abrasive-impregnated material around a core, providing a firmer, more consistent cut than an airform or unitized wheel of the same grade. Typical applications include deburring drilled holes, cleaning up stamped edges, and light surface conditioning on flat or contoured workpieces. Compatible tooling includes bench grinders and pedestal grinders.

Key Features

• Aluminum oxide abrasive for reliable cutting action on steel, cast iron, and most common metals
• Medium grade, Density 4 construction balances cut rate with workpiece surface finish
• Convolute wheel design provides firm, consistent contact and longer wheel life compared to non-woven airform styles
• 6-inch diameter and 1-inch face width fit standard bench and pedestal grinder arbors
• 1-inch center hole for direct mounting on common grinder spindles
• 4,500 RPM maximum rating suitable for typical bench grinder operating speeds

Compatibility

Designed for use on bench grinders and pedestal grinders with a 1-inch arbor. Verify that the grinder spindle speed does not exceed the 4,500 RPM maximum rating before mounting.

Installation Notes

A licensed or qualified technician should mount abrasive wheels following ANSI B7.1 safety guidelines for the use, care, and protection of abrasive wheels. Always power down and lock out the grinder before changing wheels. Inspect the wheel for cracks or damage before installation and perform a ring test to confirm integrity. Do not exceed the 4,500 RPM maximum rated speed marked on the wheel.
