3M 7000120981 Scotch-brite EX3 Convolute Deburring Wheel 14 Inch

Product Description

The 3M 7000120981 is a convolute-constructed non-woven deburring wheel from the Scotch-Brite EX3 line, engineered for aggressive edge deburring and burr removal on metal workpieces. The convolute build layers non-woven abrasive web around a core, producing a hard, dense wheel that holds its edge geometry throughout its service life. A proprietary resin system limits heat buildup and resists smearing, which reduces secondary cleaning and prep time. This wheel measures 14.5 inches in diameter and 2.7 inches in face width, and weighs 7 pounds. It is used by machinists, fabricators, and tool-and-die professionals in finishing and deburring operations on metal parts.

The Scotch-Brite EX3 wheel is suited for production deburring of ferrous and non-ferrous metal edges where consistent, repeatable material removal is required. Its non-woven construction runs cooler than bonded abrasive wheels, making it appropriate for heat-sensitive alloys and precision-ground workpieces where thermal distortion is a concern. The wheel performs at its best when presented continuously with sharp edges or metal burrs, making it a strong fit for high-volume deburring stations and bench-mounted finishing equipment.

Key Features

• Convolute construction delivers a balanced, smooth-running wheel from first use through full product life
• Highest edge retention and durability in the Scotch-Brite Deburring Wheel line for aggressive burr removal
• Non-woven web runs cool, reducing heat impact on sensitive materials and precision workpieces
• Proprietary resin system resists smearing, cutting down on clean-up and prep between operations
• Hard, dense wheel structure maintains consistent performance when presented with sharp edges or burrs

Compatibility

Designed as an OEM-style replacement or direct-fit deburring wheel for bench-mounted and floor-standing deburring machines and finishing lathes that accept a 14-inch diameter convolute wheel.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician following the equipment manufacturer's arbor and flange specifications. Power down and lock out the deburring machine before mounting or removing the wheel. Confirm that the machine spindle speed rating is compatible with the maximum RPM rating of the wheel before operation. Always dress the wheel face and verify balance before returning the machine to production use.
