3M 7100188518 Scotch-brite Exl Unitized Wheel 6 in 1/2 in Arbor

Product Description

The 3M 7100188518 is a Scotch-Brite EXL Unitized Abrasive Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. The wheel measures 6 inches in diameter with a 1/2 inch arbor bore and weighs 1.527 pounds. Its soft, conformable construction keeps the abrasive mineral in consistent contact with the workpiece, which reduces heat buildup and minimizes smearing on finished surfaces. This wheel is suited for use by metalworkers, fabricators, and industrial finishing technicians operating bench grinders or pedestal grinders in production or job-shop environments.

This unitized wheel is used in metal fabrication, light manufacturing, and industrial maintenance settings where consistent edge finishing and deburring are required. The conformable structure makes it well suited for complex-shaped parts and robotic processing applications. It handles a wide range of materials including ferrous and non-ferrous metal alloys, many plastics, and composite substrates. The wheel can run in clockwise or counterclockwise rotation, adding flexibility for various machine configurations and production setups.

Key Features

• Soft, conformable unitized construction keeps abrasive in contact with irregular and complex part geometries
• Bidirectional operation — runs clockwise or counterclockwise without performance loss
• Minimizes heat buildup, reducing risk of damage to heat-sensitive materials
• Resists smearing for cleaner finished surfaces and reduced post-process cleanup
• Wheel edge can be dressed for precise deburring, finishing, and polishing work
• Compatible with robotic and automated processing environments due to consistent conformability

Compatibility

Designed for use on bench grinders and pedestal grinders accepting a 1/2 inch arbor and accommodating a 6 inch diameter wheel. Suitable for metal alloys, many plastics, and composite materials.

Installation Notes

Installation should be performed by a qualified operator following the grinder manufacturer's instructions and applicable ANSI B7 safety standards for abrasive wheels. Power down and lock out the grinder before mounting or removing the wheel. Verify that the machine's rated speed does not exceed the maximum RPM marked on the wheel. Inspect the wheel for damage before each use and run the mounted wheel at operating speed in a guarded position for at least one minute before applying it to a workpiece.
