3M 7100112002 Sanding Disc 3 Inch P320 Grit Clean Sanding

Product Description

The 3M 7100112002 is a coated abrasive hook-and-loop sanding disc designed for finishing work in light material removal and surface preparation applications. Built on a light A-weight paper backing, this 3-inch disc uses aluminum oxide mineral for fast cutting and durable performance across a range of surfaces. The disc features an engineered multi-hole pattern that promotes active dust extraction, keeping the work surface cleaner and extending disc life. Open-coat construction paired with a load-resistant coating reduces clogging at P320 grit, making it well suited for fine finishing passes where surface quality matters.

This disc is intended for use with hook-and-loop compatible random orbital and orbital finishing sanders in woodworking, metal finishing, auto body prep, and general surface conditioning tasks. The multi-hole dust extraction pattern works with vacuum-assisted sanding systems to evacuate swarf and abrasive debris more efficiently than standard 5- or 6-hole configurations. The hook-and-loop attachment system allows fast disc changes and supports disc reuse, reducing downtime during production or service work. Residential finishing contractors, cabinet shops, auto body technicians, and industrial maintenance professionals are the primary installers of this consumable.

Key Features

• Engineered multi-hole pattern provides improved dust extraction compared to standard 5- or 6-hole disc layouts
• Open-coat construction and load-resistant coating resist clogging at fine grits to maintain cut rate and disc life
• Aluminum oxide mineral cuts fast and performs across wood, metal, and composite surfaces
• Light A-weight paper backing is optimized for finishing and fine material removal
• Hook-and-loop attachment allows quick disc changes and supports reuse over the disc service life

Compatibility

Designed for use with hook-and-loop random orbital and orbital finishing sanders equipped with a 3-inch multi-hole backup pad compatible with the disc hole pattern.

Installation Notes

Alignment of the disc hole pattern with the backup pad holes is required for effective dust extraction. Inspect the backup pad for wear or contamination before attaching a new disc, as a degraded pad face reduces holding strength. Operate the sander at the speed recommended by the tool manufacturer for the grit and material being worked. Disconnect the sander from power before changing discs.
