3M 7000045985 Convolute Deburring Wheel 8 Inch Aluminum Oxide

Product Description

The 3M 7000045985 is a convolute deburring wheel designed for aggressive material removal, edge finishing, and surface preparation on metal workpieces. Built with aluminum oxide abrasive bonded in a hard-density convolute construction, this wheel delivers consistent cut and open structure that resists loading. At a density rating of 7 with a hard grade, it is suited for deburring tasks that require firm abrasive contact and predictable wear. The wheel is rated to 4,500 RPM and fits a 3-inch center hole for secure mounting on compatible arbors and mandrels. Machinists and metalworking professionals install this wheel on production grinding and finishing equipment.

This wheel is used in industrial and production shop environments for deburring, blending, and light stock removal on ferrous and non-ferrous metals. Its 8-inch diameter and 2-inch face width make it suitable for both flat and contoured surface work. Compatible tooling includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It is a single-wheel package intended for professional metalworking applications where consistent finishing results are required across high-volume workloads.
