3M 7100010256 Sanding Disc 3 Inch P320 Grit

Product Description

The 3M 7100010256 is a 3-inch coated abrasive hook-and-loop sanding disc designed for clean, efficient material removal on painted surfaces, wood, and composites. Built on a durable, tear-resistant film backing, it uses aluminum oxide grains and features a precision multi-hole pattern that evacuates dust more effectively than standard 5- or 6-hole disc designs. The open-coat, load-resistant construction resists clogging, helping maintain cut rate and extending disc life. This disc is rated at P320 grit and is sold individually.

The 7100010256 is suited for finish sanding applications in automotive, woodworking, and general fabrication environments. The multi-hole dust evacuation pattern works with random orbital sanders equipped with hook-and-loop disc pads. Because the hole pattern does not need to align with the pad, disc changes are fast and require no repositioning. This makes the disc practical for high-turnover production settings where speed and consistency matter.

Key Features

• Precision multi-hole pattern provides superior dust extraction compared to 5- or 6-hole designs
• Open coat and load-resistant coating resists clogging to maintain cut rate and disc life
• Hook-and-loop attachment allows quick disc changes without hole alignment
• Tear-resistant film backing delivers a close-tolerance, consistent finish
• Aluminum oxide abrasive cuts faster and outlasts traditional garnet abrasives

Compatibility

Designed for use with hook-and-loop random orbital sanders accepting 3-inch discs. The multi-hole pattern does not require alignment with the sanding pad, making it compatible with a wide range of pad hole configurations.

Installation Notes

Attach the disc to a clean, dry hook-and-loop sanding pad before use. Inspect the pad surface for worn hooks that may reduce holding power and cause disc slippage. Ensure the sander is powered off before attaching or removing the disc. Dispose of worn discs promptly, as a loaded or glazed disc reduces cut efficiency and surface finish quality.
