3M 7100331753 Fibre Disc 80 Plus Grit 2 Inch

Product Description

The 3M 7100331753 is a 2-inch fibre disc designed for aggressive material removal on metal surfaces. Built around 3M Precision-Shaped Grain geometry, the disc maintains sharp cutting points throughout its full service life, delivering fast stock removal with less applied pressure than conventional abrasive discs. A built-in grinding aid helps control heat buildup, making this disc well-suited for stainless steel, non-ferrous metals, and other heat-sensitive alloys where discoloration or stress cracking is a concern. A stiff fibre backing and strong resin bond give the disc durability against tearing under sustained load.

This disc is used in grinding, beveling, weld removal, blending, and surface finishing operations. It performs across a range of application pressures, making it appropriate for heavy grinding as well as medium-pressure surface work. The design supports robotic grinding operations in addition to hand-held angle grinder applications. The 3M Roloc-style attachment system allows fast disc swaps between grit grades or applications without tools, reducing changeover time on the floor or in the field. It is sold and priced per disc, with a minimum order quantity of 200 units per the supplier unit of measure.

Key Features

• Precision-Shaped Grain maintains sharp cutting points across the full disc life for consistent fast cut rate
• Integrated grinding aid minimizes heat generation on stainless steel and other heat-sensitive alloys
• Stiff fibre backing with strong resin bond resists tearing in heavy grinding and beveling applications
• Effective for weld removal, blending, surface grinding, and robotic operations
• Roloc-compatible quick-change attachment system for fast disc swaps between grades
• Longer disc life reduces abrasive waste and changeover downtime

Compatibility

Designed for use with Roloc-compatible angle grinder backup pads accepting 2-inch quick-change fibre discs.

Installation Notes

Installation is performed by grinding and abrasives technicians or fabricators using a compatible angle grinder fitted with an appropriate backup pad. Ensure the grinder is powered off and disconnected before mounting or removing the disc. Verify the grinder RPM rating meets or exceeds the disc RPM rating before operation. Eye protection, hearing protection, and appropriate respiratory PPE should be worn per applicable safety standards during use.
