3M 7100010259 3 Inch P400 Sanding Disc Clean Sanding

Product Description

The 3M 7100010259 is a coated abrasive sanding disc designed for clean sanding applications in surface preparation and finishing work. Built on a durable film backing, this 3-inch disc uses aluminum oxide abrasive grain at P400 grit for smooth, consistent material removal. A multi-hole pattern across the disc face evacuates dust more effectively than standard 5- or 6-hole designs, extending disc life and maintaining cut rate throughout use. The hook-and-loop attachment system makes disc changes fast without requiring hole alignment to the backing pad. Finishing tradespeople, automotive body technicians, and woodworking professionals will find this disc well-suited to fine sanding stages.

This disc is intended for light to fine surface finishing on wood, painted surfaces, and similar substrates. The P400 grit designation makes it appropriate for final sanding passes before finishing or between coats. The open coat construction and load-resistant mineral bond resist clogging on resinous or softer materials. The multi-hole dust extraction pattern works with random orbital sanders equipped with dust collection ports, reducing airborne particulate at the work surface.

Key Features

• Multi-hole pattern provides superior dust evacuation compared to 5- or 6-hole disc designs
• No hole alignment required with backing pad, allowing fast disc changes
• Aluminum oxide abrasive grain cuts faster and lasts longer than garnet abrasives
• Open coat, load-resistant construction resists clogging on resinous materials
• Durable film backing is tear-resistant for consistent, close-tolerance finishing
• Hook-and-loop attachment allows disc removal and reuse during service life

Compatibility

Designed for use with 3-inch hook-and-loop random orbital sanding pads equipped with dust extraction ports. No hole alignment to the pad is required due to the multi-hole disc pattern.

Installation Notes

Installation of this disc is performed by pressing the hook-and-loop face firmly onto a compatible 3-inch backing pad. Ensure the sander is powered off and disconnected from air or electrical supply before changing discs. Inspect the backing pad for wear or contamination that could affect disc adhesion before attaching a new disc. Connect the sander to a dust collection system to take full advantage of the multi-hole evacuation pattern.
