3M 7000046071 Deburring Wheel 8 in Silicon Carbide Density 9

Product Description

The 3M 7000046071 is a convolute deburring wheel designed for aggressive edge finishing, burr removal, and surface blending on metal workpieces. Built with silicon carbide abrasive at a density rating of 9 and a hard grade, fine grit construction, this wheel delivers consistent stock removal on ferrous and non-ferrous metals. At 8 inches in diameter with a 1/2 inch face width and a 3 inch center hole, it mounts directly to bench top motors and compatible backstand or inline equipment. Maximum rated speed is 4,500 RPM. Machinists, fabricators, and finishing technicians use this wheel for production deburring and edge conditioning tasks.

This convolute wheel is suited for shop environments where controlled, repeatable deburring is required across multiple workpieces. It fits bench top motor spindles and is also compatible with inline sanders and manual backstand setups, making it adaptable to fixed and portable finishing stations. The silicon carbide abrasive cuts cleanly on aluminum, brass, titanium, and hardened steel. It is a practical choice for metalworking shops, aerospace fabrication, and general manufacturing finishing lines where burr-free edges are a production requirement.

Key Features

• Silicon carbide abrasive for sharp, consistent cut on hard and non-ferrous metals
• Density 9 hard grade construction resists compression and maintains wheel shape under load
• Fine grit specification (9SFIN) delivers smooth edge finish while still removing burrs efficiently
• Convolute wheel design provides even abrasive distribution throughout the wheel body
• 4,500 RPM maximum speed rating suitable for standard bench motor operation
• 3 inch center hole compatible with mandrel and adapter number 356

Compatibility

Compatible with bench top motors, inline sanders, and manual backstand tooling. Mandrel and adapter compatibility: number 356. Designed for use where a 3 inch arbor hole and convolute wheel format are specified.

Installation Notes

Installation should be performed by a qualified machinist or finishing technician familiar with abrasive wheel safety. Always power down and lockout the machine before mounting or removing the wheel. Verify the spindle speed does not exceed the 4,500 RPM maximum rating of this wheel before operation. Inspect the wheel for cracks or damage before each use, and ensure the mounting flanges and arbor are clean and undamaged prior to installation.
