3M 7100331749 Cubitron 3 Roloc Fibre Disc 36 Grit 3 in

Product Description

The 3M 7100331749 is a Cubitron 3 Roloc Fibre Disc engineered for medium to high-pressure grinding applications on metal. Built around re-engineered 3M Precision-Shaped Grain, the disc features curved mineral sides that maintain sharp cutting points throughout the life of the disc, delivering fast stock removal across a wide range of application pressures. At 3 inches in diameter and a 36-plus grit rating, this disc is designed for aggressive material removal. An incorporated grinding aid minimizes heat buildup, making it suitable for stainless steel and other heat-sensitive alloys where discoloration and stress cracking are concerns. A stiff fiber backing and strong resin bond provide tear resistance under sustained load.

This disc is intended for use in metal fabrication, weld removal, beveling, blending, and surface grinding on ferrous and non-ferrous metals including stainless steel. The Roloc quick-change attachment system allows fast disc swaps between grades or applications, reducing downtime in production and field environments. It is suited for use with compatible Roloc-style angle grinders and die grinders in both shop and on-site settings. Licensed trades and metal fabricators working on structural, pipe, and sheet metal applications will find the consistent cut rate and extended disc life beneficial for volume grinding work.

Key Features

• Re-engineered Precision-Shaped Grain maintains sharp cutting points for fast stock removal with less applied pressure
• Incorporated grinding aid reduces grinding temperatures on stainless steel and other heat-sensitive alloys, minimizing discoloration and stress cracks
• Stiff fiber backing and strong resin bond deliver durability and tear resistance under medium to high-pressure grinding loads
• 36-plus grit rating supports aggressive material removal, weld grinding, and beveling operations
• Roloc quick-change attachment system allows rapid disc changes without tools, reducing changeover time
• Extended disc life design increases parts completed per disc and reduces abrasive waste and downtime

Compatibility

Designed for use with Roloc-style quick-change disc grinders and die grinders that accept TR-style threaded attachments. Suitable for grinding ferrous metals, stainless steel, and non-ferrous heat-sensitive alloys.

Installation Notes

Installation and disc changes should be performed by operators familiar with angle grinder and die grinder safety practices. Power down and disconnect the tool from its power source before mounting or removing the disc. Verify the tool spindle speed does not exceed the rated maximum speed of the disc before operation. Follow applicable ANSI and OSHA abrasive wheel safety standards when operating grinding equipment.
