3M 7100227734 Hookit Microfinishing Film Disc 11 in 60um

Product Description

The 3M 7100227734 is a Hookit microfinishing film disc engineered for precision surface finishing across a range of trade and industrial applications. Built on a polyester film backing with micron-graded, resin-bonded abrasive, this 11-inch disc delivers aggressive cut combined with a uniform finish. The load-resistant coating reduces clogging, extending disc life and maintaining consistent cut rate throughout the service life. At a 60-micron grade, it is suited for controlled material removal where surface quality and finish consistency are critical. Hook-and-loop attachment makes disc changes fast and secure on compatible Hookit backup pads.

This disc is designed for use on plastic, fiberglass, wood, metal, and solid-surface composites. It is a common choice in bodywork, composite fabrication, woodworking, and precision metal finishing operations where a controlled, repeatable finish is required. The 11-inch diameter suits larger-format random orbital and disc sanders used in production and professional finishing environments. The hook-and-loop system is particularly efficient in high-turnover operations where frequent disc changes are routine.

Key Features

• 60-micron precision grading for controlled, uniform material removal
• Polyester film backing provides dimensional stability and tear resistance
• Load-resistant coating extends disc life and maintains cut efficiency
• Hook-and-loop (Hookit) attachment for fast, secure pad mounting
• Compatible with plastic, fiberglass, wood, metal, and solid-surface composites
• 11-inch diameter suits larger-format disc sanders used in professional finishing

Compatibility

Designed for use with Hookit hook-and-loop backup pads accepting an 11-inch disc. Suitable for professional finishing applications on plastic, fiberglass, wood, metal, and solid-surface composites.

Installation Notes

Install onto a compatible Hookit backup pad rated for the disc diameter before powering the tool. Confirm the tool does not exceed the rated maximum speed of 2000 RPM before operation. Power down and disconnect the tool from its power source before mounting or removing the disc. Inspect the hook-and-loop interface for wear before each use to ensure secure disc retention during operation.
