3M 7100138372 Unitized Convolute Deburring Wheel

Product Description

The 3M 7100138372 is a Scotch-Brite EXL unitized convolute abrasive wheel designed for deburring, smoothing, and surface finishing on metal alloys, plastics, and composites. Its soft, conformable construction keeps the abrasive in consistent contact with the workpiece, making it effective on complex and irregular part geometries. The wheel measures 12.5 inches in diameter and 1.69 inches wide, weighing 1.3 pounds. The aluminum oxide abrasive construction minimizes heat build-up, which reduces the risk of surface damage on heat-sensitive materials. This wheel is sold individually and is suited for bench-mounted or automated machine applications in fabrication, metalworking, and finishing operations.

This wheel is used in industrial and fabrication environments where consistent edge finishing and deburring of metal parts, plastics, and composite components is required. It is well suited for robotic or automated processing setups because its conformable construction allows the abrasive to follow complex part profiles without losing contact. Manual bench grinder applications are also common, particularly in shops handling a high volume of parts requiring burr removal or pre-finishing surface prep.

Key Features

• Soft, conformable unitized construction conforms to complex part shapes including robotic processing applications
• Wheel edge can be dressed to restore cutting action for deburring, finishing, and polishing
• Operates in both clockwise and counterclockwise rotation directions
• Minimizes heat build-up to protect heat-sensitive base materials
• Resists smearing for cleaner finished surfaces and reduced prep time
• Available in multiple density grades from soft and conformable to hard and aggressive

Compatibility

Designed for use on metal alloys, plastics, and composite materials. Suitable for bench grinders, pedestal grinders, and automated or robotic finishing equipment that accept convolute unitized wheel configurations.

Installation Notes

Mount this wheel on a compatible arbor-equipped bench or pedestal grinder following the equipment manufacturer's specifications for arbor size and flange configuration. Ensure the machine spindle speed does not exceed the maximum RPM rating marked on the wheel. Power down and lock out the grinder before mounting or removing the wheel. Wear appropriate eye and face protection during operation.
