3M 7100100962 Roloca 787C 2 Inch 80 Grit Fibre Disc

Product Description

The 3M 7100100962 is a coated abrasive fibre disc in the Roloca 787C series, engineered for rapid stock removal on hard-to-grind metals. At 2 inches in diameter and 80 grit, it uses 3M Precision Shaped Grain to deliver higher cut rates and a cooler cutting action compared to conventional fibre discs. A built-in grinding aid manages heat at the contact surface, making this disc well suited for heat-sensitive alloys. The Roloca attachment system locks the disc securely to the backing pad without tools. Licensed tradespeople and fabricators working in metal finishing, weld prep, and surface blending are the primary installers of this disc.

This disc is designed for aggressive material removal and finish refinement on stainless steel and high nickel alloys. Typical applications include weld removal, weld blending, beveling, edge chamfering, and surface conditioning. The stiff fibre backing and strong resin bond resist tearing under load, supporting sustained use in heavy fabrication and maintenance environments. The 80 grit cut rate makes it appropriate for initial stock removal and weld grinding before transitioning to finer finishing steps.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and cooler grinding versus conventional fibre discs
• Built-in grinding aid reduces heat buildup on heat-sensitive alloys such as stainless steel and high nickel alloys
• Roloca attachment system locks disc to backing pad securely with no tools required
• Stiff fibre backing and strong resin bond provide durability and tear resistance under heavy loads
• Suited for weld removal, beveling, edge chamfering, and finish blending
• 2 inch diameter at 80 grit supports aggressive stock removal in confined or detail work areas

Compatibility

Designed for use with compatible Roloca-style angle grinder backing pads rated for 2 inch coated abrasive fibre discs at speeds up to 30000 RPM.

Installation Notes

Metal fabricators and grinding technicians install this disc type. Confirm the backing pad and grinder are rated for the disc diameter and maximum operating speed before mounting. Always inspect the disc for damage before use and never exceed the rated 30000 RPM. Follow applicable ANSI B7 safety standards for the use of abrasive products and wear appropriate PPE including face shield and gloves.
