3M 7000139225 Trizact 466LA Abrasive Disc Roll 6 Inch

Product Description

The 3M 7000139225 is a coated abrasive disc roll from the Trizact 466LA line, designed for precision surface finishing on automotive paint and similar applications. It uses 3M microreplication technology to form micron-graded silicon carbide particles into uniform pyramids on a non-compressible 3-mil polyester film backing. This construction delivers consistent, controlled material removal that starts sharp and stays sharp throughout the disc life, making it a reliable choice for technicians who need repeatable results in paint defect correction and finishing work.

This disc roll is suited for two-step automotive paint defect repair processes where a polish-ready finish is required. It performs well on mini random orbital sanders and similar low-profile finishing tools. The silicon carbide mineral is available in three very fine micron grades, allowing technicians to match the abrasive to the specific stage of their finishing sequence. Typical users include automotive body technicians and surface finishing specialists working on clear coat correction and paint preparation.

Key Features

• Microreplication technology forms silicon carbide into uniform abrasive pyramids for consistent cut rate
• Non-compressible 3-mil polyester film backing maintains flatness and prevents undercutting
• Micron-graded silicon carbide mineral in three very fine grades for controlled finishing
• Optimized for mini random orbital sanders to produce polish-ready surfaces
• Designed for the 3M two-step paint defect repair process on automotive finishes
• Roll format provides multiple discs per unit, reducing changeover interruptions

Compatibility

Designed as an OEM-style replacement and finishing solution for use with mini random orbital sanders and similar tools in automotive paint correction applications.

Installation Notes

Installation and disc changes should be performed with the tool powered off and disconnected from any air or electrical supply. Confirm the sander backing pad diameter matches the 6-inch disc size before attaching. Follow the tool and abrasive manufacturer guidelines for pad speed and pressure to avoid heat buildup on clear coat surfaces. Dispose of spent discs per local shop waste guidelines.
