3M 7000045948 Deburring Wheel 1-1/2 in Aluminum Oxide

Product Description

The 3M 7000045948 is an aluminum oxide unitized deburring wheel designed for edge finishing, light deburring, and surface blending on metal workpieces. It measures 1-1/2 inches in diameter with a 1/8-inch face width and a 3/16-inch center hole. The wheel carries a Density 8 Hard grade rating and a coarse abrasive classification, making it suited for aggressive material removal while maintaining workpiece integrity. Rated to 30,100 RPM, it is compatible with a range of high-speed rotary tools. Installation and use are typically handled by machinists, fabricators, toolroom technicians, and maintenance trades working with precision metal components.

This deburring wheel is intended for use on centerless grinders, die grinders, inline sanders, manual backstands, and pressure-assist backstands. It is well suited for deburring drilled holes, ground edges, and machined surfaces in both production and maintenance environments. The unitized wheel construction provides consistent cut rate and finish throughout the wheel's service life, making it a reliable choice for repetitive finishing tasks on ferrous and non-ferrous metals.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician familiar with abrasive wheel safety requirements. Before mounting, verify that the tool spindle speed does not exceed the 30,100 RPM maximum rating of this wheel. Inspect the wheel for cracks or damage before use and ensure the center hole seats properly on the mandrel or spindle. Follow ANSI B7.1 safety standards for the mounting and use of abrasive wheels.
