3M 7100001140 Unitized Abrasive Wheel 1 in Silicon Carbide

Product Description

The 3M 7100001140 is a Scotch-Brite EXL unitized abrasive wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. At 1 inch in diameter, this silicon carbide wheel uses a soft, conformable construction that keeps the abrasive material in consistent contact with the workpiece surface. The unitized layered build maintains its shape and cutting action throughout use, resisting smearing and minimizing heat buildup. Fabricators, machinists, and finishing technicians use this wheel on bench grinders and automated or robotic finishing equipment.

This wheel is suited for edge deburring, light surface conditioning, and finish work on metal alloys and many plastics and composites. Its small 1-inch diameter makes it appropriate for detail work, tight geometries, and component-level finishing tasks. The wheel can be dressed to maintain a consistent edge profile, which is useful for controlled deburring and polishing passes. It is sold individually and fits applications where conformability to complex part shapes is a priority, including both manual and robotic processing setups.

Key Features

• Silicon carbide abrasive construction for effective cutting on metals, plastics, and composites
• Conformable, layered unitized build maintains contact with complex and irregular part geometries
• Wheel edge can be dressed for controlled deburring, finishing, and polishing passes
• Operates in clockwise or counterclockwise rotation, compatible with standard bench and automated equipment
• Resists smearing for cleaner finished surfaces with less secondary preparation
• Minimizes heat buildup, reducing risk of thermal damage on heat-sensitive materials

Compatibility

Designed as a small-diameter unitized wheel for use on bench grinders, die grinders, and robotic finishing equipment that accept 1-inch diameter abrasive wheels with the appropriate arbor size.

Installation Notes

Installation and mounting should be performed by a qualified machinist or finishing technician following the equipment manufacturer's arbor and speed specifications. Confirm the spindle speed rating of the equipment does not exceed the maximum RPM rating of the wheel before operation. Power down and lock out the equipment fully before mounting or removing the wheel. Eye protection and appropriate PPE should be worn during all grinding and finishing operations.
