3M 7000046040 Scotch-brite EX2 Convolute Deburring Wheel

Product Description

The 3M 7000046040 is a convolute-constructed deburring wheel from the Scotch-Brite EX2 line, designed for mid-range aggressiveness and hardness across a broad range of surface finishing operations. It handles deburring, edge radiusing, blending, polishing, and finishing on metal alloys, many plastics, and composites. The wheel measures 12.5 inches in diameter and 1.69 inches wide, weighing 1.5 pounds. It is suited for use on stationary finishing machines in fabrication shops, machine shops, and light manufacturing environments where controlled material removal and consistent surface quality are required.

This wheel is applied in metalworking and fabrication settings where burrs, sharp edges, and surface irregularities need to be addressed without excessive heat buildup or smearing. It is particularly effective when consistently presented with sharp edges or fresh metal burrs. The convolute construction delivers repeatable contact geometry, making it a practical choice for production deburring runs on a variety of metal parts and some plastic or composite components.

Key Features

• Mid-range aggressiveness and hardness suitable for deburring, edge radiusing, blending, polishing, and finishing
• Convolute construction supports operation in both clockwise and counterclockwise directions
• Wheel edge can be dressed to maintain effective cutting action on metals, plastics, and composites
• Resists smearing for cleaner finished surfaces with less secondary preparation
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive materials
• Layered, unitized construction provides durability across extended production use

Compatibility

Designed for use on stationary bench or pedestal finishing machines that accept convolute deburring wheels; suitable for deburring and finishing applications on metal alloys and many plastics and composites.

Installation Notes

Installation should be performed by a qualified operator familiar with abrasive wheel safety and the machine manufacturer's mounting specifications. Power down and lock out the finishing machine before mounting or removing the wheel. Confirm that the machine's rated speed is compatible with the wheel's rated RPM before operation. Inspect the wheel for damage before each use and never operate a cracked or compromised wheel.
