3M 7000120740 Scotch-brite Exl Unitized Wheel 2 in 1/4 in Arbor

Product Description

The 3M 7000120740 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and finishing metal alloys, plastics, and composites. The wheel measures 2 inches in diameter and mounts on a 1/4 inch arbor. Its soft, conformable construction keeps abrasive media in consistent contact with the workpiece surface, minimizing heat buildup and reducing the risk of smearing or discoloration on heat-sensitive materials. The aluminum oxide abrasive grain delivers reliable cut and finish across a range of substrate types. This wheel is well suited for bench grinder, die grinder, and robotic finishing operations in fabrication and manufacturing environments.

This wheel is used in applications that require controlled deburring, edge finishing, and surface preparation on metal alloys, many plastics, and composite materials. The unitized construction allows operation in both clockwise and counterclockwise directions, making it adaptable to a range of spindle configurations. It is a practical choice for machinists, metal fabricators, and finishing technicians working on precision parts where edge quality and surface consistency matter. The conformable structure also suits robotic and automated processing setups where the abrasive must follow complex contours.

Key Features

• Soft, conformable unitized construction maintains abrasive contact on complex and irregular part geometries
• Operates in both clockwise and counterclockwise directions for flexible spindle compatibility
• Minimizes heat buildup to protect heat-sensitive metals, plastics, and composites during finishing
• Resists smearing for cleaner surface results and reduced prep time between operations
• Wheel edge can be dressed to maintain consistent deburring and polishing performance
• Tough layered construction supports use in robotic and automated finishing applications

Compatibility

Designed as a unitized abrasive wheel for use with bench grinders, die grinders, and automated finishing equipment accepting a 1/4 inch arbor and accommodating a 2 inch diameter wheel.

Installation Notes

Installation and operation should be performed by qualified machinists or finishing technicians familiar with abrasive wheel safety requirements. Power down and de-energize all equipment before mounting or changing the wheel. Verify that the spindle speed rating of the grinder or tool does not exceed the maximum RPM rating of the wheel before operation. Always use appropriate eye protection and follow applicable ANSI B7.1 safety standards for abrasive wheel use.
