3M 7000046078 Convolute Deburring Wheel 8 in Silicon Carbide

Product Description

The 3M 7000046078 is a convolute deburring wheel engineered for aggressive surface conditioning and edge deburring on metal workpieces. Built with silicon carbide abrasive at a hard density grade of 9, this wheel delivers consistent stock removal and a fine finish in a single pass. It measures 8 inches in diameter with a 1-inch face width and a 3-inch center hole, making it compatible with standard arbor-style mounting. Rated to 4,500 RPM, it is suited for sustained use on automated and manual grinding equipment. Metalworking shops and industrial maintenance technicians are the primary installers and operators.

This deburring wheel is used in metalworking applications where consistent edge breaking, burr removal, and surface blending are required. Tooling compatibility includes centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. It is appropriate for both production-line and bench-level deburring tasks in fabrication, machining, and maintenance environments. The fine grade silicon carbide construction suits finishing passes on ferrous and non-ferrous metals where tight tolerances and clean edges are required.

Key Features

• Silicon carbide abrasive provides sharp, consistent cutting action on metal surfaces
• Density grade 9 hard construction maintains wheel integrity under sustained load
• Fine grade abrasive delivers smooth edge finishing and burr removal in one step
• 4,500 RPM maximum speed rating suits a wide range of power grinding equipment
• Convolute wheel construction allows the abrasive to conform to irregular edge profiles
• Compatible with centerless grinders, die grinders, inline sanders, and manual or pressure assist backstands

Compatibility

Designed for use with centerless grinders, die grinders, inline sanders, manual backstands, and pressure assist backstands. The 3-inch center hole fits standard arbor configurations on compatible equipment. Verify arbor size and maximum spindle speed before mounting.

Installation Notes

Installation should be performed by a qualified metalworking technician or machine operator. Power down and lock out the host machine before mounting or removing the wheel. Confirm the host machine spindle speed does not exceed the 4,500 RPM maximum rating marked on the wheel. Inspect the wheel for visible damage before each use and do not operate a cracked or damaged wheel.
