3M 7100104897 Ceramic Fibre Disc 4 Inch 36 Grit

Product Description

The 3M 7100104897 is a coated abrasive fibre disc engineered for ultra-rapid stock removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, a ceramic abrasive mineral formed into consistent geometric shapes, this 4-inch disc cuts faster and runs cooler than conventional fibre discs. At 36 grit, it is suited for aggressive material removal. A grinding aid is integrated into the bond system to reduce heat buildup at the workpiece surface, making it a reliable choice for heat-sensitive alloys. Stiff fibre backing and a strong resin bond contribute to tear resistance and extended disc life.

This disc is designed for weld removal, weld blending, beveling, edge chamfering, and finish refinement on stainless steel and high-nickel alloys. It fits standard angle grinders equipped with compatible disc pad face plates and hubs. Typical users include fabricators, pipefitters, welders, and maintenance technicians working with stainless steel components and nickel-alloy materials in industrial and commercial environments.

Key Features

• 3M Precision Shaped Grain delivers higher cut rates and cooler grinding compared to conventional abrasive minerals
• 36-grit ceramic abrasive handles aggressive applications including weld grinding, beveling, and edge chamfering
• Integrated grinding aid minimizes heat generation on heat-sensitive alloys such as stainless steel and high-nickel materials
• Stiff fibre backing and strong resin bond provide durability and tear resistance under heavy load
• 4-inch diameter fits standard angle grinder pad systems
• Compatible with 3M disc pad face plates and hubs sold separately

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on stainless steel and high-nickel alloys. Fits standard angle grinders accepting 4-inch fibre discs.

Installation Notes

Fibre discs of this type are installed and replaced by fabricators, welders, or maintenance technicians using compatible angle grinder back-up pads. Inspect the back-up pad and disc for damage before mounting. Ensure the grinder is powered off and unplugged before changing discs. Follow the grinder and disc manufacturer guidelines for maximum operating RPM and safe guard requirements per ANSI B11 and applicable shop safety standards.
