3M 7100084760 Sanding Disc 3 Inch P400 Grit Clean Sanding

Product Description

The 3M 7100084760 is a 3-inch hook-and-loop abrasive sanding disc designed for clean sanding applications with aggressive dust evacuation. Built on a durable, tear-resistant film backing, this disc uses aluminum oxide grains and an open-coat, load-resistant surface to maintain cut rate and extend disc life. The multi-hole pattern evacuates dust more effectively than standard 5- or 6-hole designs. Licensed contractors, finish carpenters, auto body technicians, and surface prep professionals use this disc where consistent finish tolerance and low clogging are required.

This disc is suited for fine finish sanding on wood, painted surfaces, and composites where P400 grit is appropriate. The multi-hole pattern does not require alignment with the pad holes, allowing fast disc swaps without downtime. It is sized at 3 inches in diameter and attaches via a hook-and-loop interface, making it compatible with standard random-orbit and orbital sanders that accept hook-and-loop backed discs of that diameter.

Key Features

• Precise multi-hole pattern provides excellent dust extraction without requiring hole alignment
• Open-coat, load-resistant coating resists clogging to sustain cut performance and extend disc life
• Aluminum oxide abrasive grain cuts faster and lasts longer than traditional garnet
• Tear-resistant film backing delivers close-tolerance, consistent surface finish
• Hook-and-loop attachment allows quick disc changes and reuse across the disc life

Compatibility

Designed for use with hook-and-loop random-orbit and orbital sanders accepting 3-inch discs. The multi-hole pattern is compatible with a range of pad hole configurations and does not require hole alignment for proper dust extraction.

Installation Notes

Attach the disc to a clean, dry hook-and-loop sanding pad before operation. Inspect the pad surface before each disc change to ensure the hook material is free of debris that could prevent secure attachment. Operate the sander at the speed recommended for the grit level and substrate to avoid heat buildup. Wear appropriate respiratory protection and use dust collection equipment in accordance with applicable safety guidelines.
