3M 7100101185 Hook Loop Disc 7 in Silicon Carbide Super Fine

Product Description

The 3M 7100101185 is a 7-inch hook and loop abrasive disc designed for surface preparation, blending, and finishing work on metal, wood, and composite materials. Built with a non-woven silicon carbide construction and rated Super Fine grade, this disc delivers consistent scratch patterns and light material removal without loading. The flexible backing conforms to contoured surfaces, making it well suited for detail work and finish blending. It mounts to any compatible hook and loop backup pad and spins safely up to 6000 RPM. Fabricators, metalworkers, and finishing technicians reach for this disc when surface quality matters as much as stock removal.

This disc fits standard finishing and surface conditioning applications in both shop and field environments. The Super Fine silicon carbide abrasive is appropriate for final-stage surface prep before coating, light deburring, and oxide removal on ferrous and non-ferrous metals. The gray non-woven construction also sees use on plastics and composites where aggressive abrasives would cause damage. No vacuum holes are present, so it is best paired with backup pads that do not rely on dust extraction through the disc face.

Key Features

• 7-inch diameter fits standard hook and loop backup pads
• Silicon carbide abrasive material for consistent, fine scratch patterns
• Super Fine grade suited for finish blending and light surface conditioning
• Non-woven construction resists loading and conforms to contours
• Flexible backing for use on curved and irregular surfaces
• Rated to 6000 RPM maximum operating speed

Compatibility

Designed for use with hook and loop backup pads accepting 7-inch abrasive discs. No vacuum holes are present; select a solid-face or non-perforated backup pad for proper fitment.

Installation Notes

This disc is installed and removed by hand on a hook and loop backup pad mounted to a right-angle grinder or random-orbit tool. Verify the tool's rated RPM meets or exceeds the 6000 RPM maximum before use. Inspect the disc for tears or separation before each use and replace if the non-woven web shows signs of delamination. Always wear appropriate eye protection and follow applicable shop safety procedures when operating rotary abrasive tools.
