3M 7100078152 Hook Loop Sanding Disc 80 Grit 6 in

Product Description

The 3M 7100078152 is a 6-inch hook and loop sanding disc designed for surface preparation, finish sanding, and stock removal on wood, painted surfaces, and composites. The disc uses aluminum oxide abrasive on a C-weight paper backing, placing it in the medium-stiffness range suited for flat and low-contour work. At 80 grit, it cuts aggressively enough to remove material quickly while leaving a surface ready for finer finishing passes. The hook and loop attachment system allows fast disc swaps on compatible random orbital and disc sanders, reducing downtime during production or service work. The gold disc color is part of the 236U series and helps operators track wear visually.

This disc is appropriate for residential and light commercial applications including cabinet finishing, floor prep, drywall feathering, and general woodworking. It is also used in vehicle body shops and maintenance environments for paint scuffing and surface conditioning. The flexible backing conforms modestly to workpiece contours. Vacuum holes are included to support dust extraction when used with a vented backing pad and a connected vacuum or dust collector, keeping the work surface visible and reducing airborne particulate.

Key Features

• 80 grit aluminum oxide abrasive for aggressive material removal and efficient stock reduction
• 6-inch diameter fits standard hook and loop random orbital sanders
• C-weight paper backing provides a balance of flexibility and support for flat and low-contour surfaces
• Vacuum holes included for compatibility with dust-extraction backing pads
• Flexible construction allows moderate conformability to workpiece shape
• 236U series gold disc with visual wear indicator coloring

Compatibility

Designed as a hook and loop replacement disc for 6-inch random orbital sanders and disc sanders equipped with hook and loop backing pads that include dust-extraction port alignment.

Installation Notes

Installation requires no tools — press the disc firmly onto a clean, dry hook and loop backing pad to ensure full engagement across the face. Disconnect the sander from power before changing discs. Inspect the backing pad regularly for worn hooks that reduce disc retention, which can cause disc ejection during operation. Use with an appropriate dust extraction system where required by site safety or local regulations.
