3M 7010309845 Scotch-brite Exl Unitized Wheel 4 in Ao

Product Description

The 3M 7010309845 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and finishing operations on metal alloys, plastics, and composites. The wheel measures 4 inches in diameter and mounts via a 1/4-inch arbor, making it compatible with standard bench grinders and right-angle tools. Its soft, conformable construction keeps the abrasive mineral in continuous contact with the workpiece surface, which is especially useful on complex profiles and contoured edges. The aluminum oxide (AO) abrasive mineral provides consistent cutting action while minimizing heat buildup, reducing the risk of thermal damage to heat-sensitive materials.

This unitized wheel is suited for metalworking, fabrication, and finishing applications in industrial and production environments. It is commonly used by machinists, fabricators, and maintenance technicians for edge deburring, surface blending, and pre-polish finishing on ferrous and non-ferrous metals. The wheel also performs on many plastics and composites, making it a versatile tool for mixed-material shops. Its layered, unitized construction allows operation in both clockwise and counterclockwise directions, providing flexibility in tool setup and orientation.

Key Features

• Soft, conformable consistency maintains abrasive contact on complex and contoured part geometries
• Layered unitized construction supports clockwise and counterclockwise operation
• Aluminum oxide abrasive mineral for consistent cut on metal alloys, plastics, and composites
• Minimizes heat buildup to protect heat-sensitive workpiece materials
• Resists smearing for cleaner surface finishes and reduced prep time
• Wheel edge can be dressed to restore cutting performance for deburring, finishing, and polishing

Compatibility

Designed for use on metal alloys including ferrous and non-ferrous materials, as well as many plastics and composites. Fits tools and bench grinders equipped with a 1/4-inch arbor.

Installation Notes

Installation should be performed by a qualified technician familiar with abrasive wheel mounting procedures. Ensure all power tools are fully de-energized and unplugged before mounting or removing the wheel. Verify that the arbor size and tool RPM rating are compatible with this wheel before operation. Follow ANSI B7.1 guidelines and the tool manufacturer's instructions for safe abrasive wheel use.
