3M 7100331754 Cubitron 3 Roloc Fibre Disc 36+ 2 Inch

Product Description

The 3M 7100331754 is a Cubitron 3 Roloc Fibre Disc rated at 36-plus grit and sized at 2 inches in diameter. It is built around re-engineered 3M Precision-Shaped Grain, a triangular abrasive mineral geometry that maintains sharp cutting points across the full life of the disc. The disc delivers fast stock removal at a range of application pressures, making it suited for heavy grinding, beveling, weld removal, and blending on metals including stainless steel and other heat-sensitive alloys. An incorporated grinding aid reduces heat buildup at the workpiece surface, helping to minimize discoloration and the risk of stress cracks. Licensed trade professionals and fabrication shops install and use this disc with compatible right-angle grinders.

This fibre disc is intended for medium- to high-pressure grinding applications on ferrous and non-ferrous metals. Its stiff fiber backing and strong resin bond provide tear resistance under sustained grinding loads. The Roloc quick-change attachment system allows fast disc swaps between grit grades or applications without additional tooling. Typical use cases include surface grinding, weld blending, and deburring operations in fabrication, maintenance, and repair environments where minimizing heat input to heat-sensitive alloys such as stainless steel is a priority.

Key Features

• Re-engineered Precision-Shaped Grain maintains sharp cutting points and self-sharpens as the abrasive wears, sustaining cut rate across disc life
• Incorporated grinding aid minimizes grinding temperatures on stainless steel and other heat-sensitive alloys, reducing discoloration and stress crack risk
• Stiff fiber backing and strong resin bond provide durability and tear resistance for medium- to high-pressure grinding, beveling, and weld removal
• Requires less operator pressure than conventional abrasives, reducing fatigue during extended grinding operations
• Roloc quick-change attachment system enables fast disc changes between grades or applications without additional tools
• Designed for longer disc life and more parts completed per disc, reducing changeout frequency and abrasive waste

Compatibility

Designed as a quick-change fibre disc compatible with standard Roloc-style right-angle grinder attachments accepting 2-inch TR-type discs.

Installation Notes

Installation and use of grinding discs should be performed by qualified operators following applicable workplace safety standards. Before mounting or changing a disc, power down and disconnect the grinder from its power source. Inspect the disc for damage before each use and do not use a disc that shows tears, cracks, or delamination. Always use appropriate personal protective equipment including eye protection, gloves, and hearing protection when operating grinding equipment.
