3M 7100188540 Scotch-brite Exl Unitized Wheel 6 in

Product Description

The 3M 7100188540 is a Scotch-Brite EXL Unitized Wheel designed for smoothing, deburring, and surface finishing on metal alloys, plastics, and composites. Built with a layered, unitized construction, the wheel delivers consistent abrasive action across the full working face. The 6-inch diameter and 1-inch arbor sizing fit standard bench grinders and pedestal units commonly used in fabrication and metalworking shops. It weighs 0.851 pounds and measures approximately 6.63 inches in both length and width, with a 2.63-inch height. Available in multiple densities, from soft and conformable to hard and aggressive, allowing the tech to match the wheel to the application requirement.

This wheel is well suited for deburring, edge finishing, blending, and light polishing operations in fabrication, welding, and general metalworking environments. It performs on ferrous and non-ferrous metal alloys as well as many plastics and composites. The conformable construction makes it particularly effective for complex-shaped parts and robotic or automated processing setups where consistent abrasive contact is critical. It can be dressed to maintain a sharp working edge throughout its service life.

Key Features

• Layered, unitized construction operates in both clockwise and counterclockwise directions
• Conformable consistency maintains abrasive contact on complex and contoured part geometries
• Wheel edge can be dressed for effective deburring, finishing, and polishing
• Minimizes heat build-up, reducing thermal impact on heat-sensitive materials
• Resists smearing for cleaner surface results and reduced prep time
• Multiple density and grade options available for a wide range of material and finish requirements

Compatibility

Designed for use on standard bench grinders and pedestal grinders equipped with a 1-inch arbor. Suitable for use on metal alloys, plastics, and composites as stated by the manufacturer.

Installation Notes

Mount this wheel on a properly guarded bench or pedestal grinder rated for the wheel diameter before operation. Power down and lock out the grinder before mounting or changing the wheel. Confirm arbor size and spindle speed rating are compatible before running. Follow applicable ANSI B11 and OSHA grinding safety guidelines during setup and use.
