Norton 66254414832 Deburring Wheel 3 Inch Aluminum Oxide

Product Description

The NORTON 66254414832 is an aluminum oxide unitized deburring wheel rated at Density 5 with a medium abrasive grade. It measures 3 inches in diameter with a 0.25-inch face width and a 0.25-inch center hole, making it compact and well-suited for precision deburring, blending, and light surface finishing on metal workpieces. The unitized construction bonds abrasive fibers throughout the wheel body, allowing it to cut consistently as the wheel wears. At 0.0495 pounds, it is lightweight and easy to handle during extended use. Machinists, fabricators, and metal finishing technicians typically install and use this wheel in production and maintenance settings.

This wheel is designed for deburring, edge blending, and surface conditioning on ferrous and non-ferrous metals. The medium grade and Density 5 rating make it suitable for moderate material removal without aggressive surface damage. Its 0.25-inch center hole fits standard mandrels used across a wide range of handheld and stationary grinding equipment. It is appropriate for use in industrial, shop, and field repair applications where controlled, consistent finishing is required.

Installation Notes

Mounting should be performed by a qualified machinist or tool operator following the grinder manufacturer's instructions and applicable ANSI B7.1 safety standards for abrasive wheels. Disconnect and lock out power to the grinder before mounting or removing the wheel. Verify that the grinder's maximum RPM rating meets or exceeds the wheel's rated speed before operation. Inspect the wheel for visible damage or cracks prior to each use and do not operate a damaged wheel.
