3M 7100117384 Trizact 464LA Abrasive Disc Roll 1.375 in

Product Description

The 3M 7100117384 is a Trizact 464LA finesse film abrasive disc roll designed for precision surface finishing in automotive paint defect repair applications. Built on a film backing with silicon carbide abrasive mineral, this disc features a microreplicated surface topography that actively channels sanding debris away from the cutting face. That debris-shedding geometry reduces loading, extends disc life, and maintains consistent cut throughout the life of the abrasive. Each disc measures 1.375 inches in diameter and is supplied in roll form for efficient dispensing during high-volume finishing work.

This disc roll is suited for use in automotive refinishing environments where controlled, repeatable surface preparation is required before polishing. It is designed for use with mini random orbital or orbital sanders and is well matched to the 3M two-step paint defect repair process. The microreplicated abrasive structure starts sharp and maintains its cutting geometry longer than conventional coated abrasives, delivering more predictable finish results on automotive clearcoat and paint surfaces. Most common surface defects are addressed quickly, supporting improved productivity in a shop environment.

Key Features

• Microreplicated silicon carbide abrasive maintains sharpness throughout disc life for consistent cut performance
• Surface topography channels debris away from the disc face, reducing loading and extending usable life
• 1.375-inch diameter designed for use with mini random orbital and orbital sanders
• Supplied in roll form for convenient, high-efficiency dispensing
• Designed for the 3M two-step paint defect repair process for automotive finishes
• Film backing supports precise finesse finishing and polish-ready surface results

Compatibility

Designed for use with mini random orbital and orbital sanders in automotive paint finishing and defect repair applications. Suited for clearcoat and painted surface preparation prior to polishing.

Installation Notes

Installation and use of abrasive disc rolls should be performed by experienced finishing technicians familiar with orbital sanding equipment and automotive refinishing procedures. Ensure the sander is powered off and the backing pad is clean and undamaged before attaching the disc. Use appropriate eye protection and respiratory protection when sanding painted surfaces. Follow equipment manufacturer guidelines for pad speed ratings to avoid disc failure or surface damage.
