3M 7100138303 Radial Bristle Brush Disc T-c 80 Refill

Product Description

The 3M 7100138303 is a radial bristle brush replacement disc designed to extend the working life of 3M Brite Radial Bristle Brush assemblies. These discs mount to a benchmotor or compatible rotary tool and deliver consistent, controlled surface finishing with minimal applied pressure. Each refill disc is engineered for cleaning, light deburring, and coating removal across metal, composite, and other hard surfaces. The T-C 80 designation indicates the disc type and abrasive grade. A universal benchmotor adapter is included in the package, making the refill ready for immediate use without additional hardware.

These replacement discs are suited for maintenance shops, fabrication environments, and trade professionals who routinely clean welds, remove oxidation, strip light coatings, or prep surfaces before finishing. The radial bristle design conforms to irregular contours and reaches into grooves and tight areas where flat abrasives cannot. They serve as a safer alternative to wire wheel brushes, reducing the risk of wire fragment ejection during operation. Typical users include metal fabricators, HVAC sheet metal techs, pipefitters, and general maintenance professionals.

Key Features

• Replaces wire brushes for surface cleaning and coating removal with reduced hazard of wire fragment ejection
• Cleans and preps surfaces with minimal applied pressure, reducing operator fatigue
• T-C 80 grade provides a medium abrasive cut suitable for general-purpose cleaning and light material removal
• Radial bristle construction conforms to contoured and irregular work surfaces
• Includes universal benchmotor adapter for out-of-package readiness
• Compatible with a variety of coatings and surface materials

Compatibility

Designed as an OEM-style refill replacement for 3M Brite Radial Bristle Brush assemblies used with standard benchtop motors and compatible rotary finishing tools.

Installation Notes

Installation is performed by maintenance and fabrication professionals familiar with benchmotor and rotary tool operation. Power down and disconnect the tool from its power source before mounting or removing any disc. Ensure the spindle adapter is properly seated and secured before resuming operation. Always confirm the tool RPM rating does not exceed the maximum rated speed of the disc, and use appropriate eye and face protection during use.
