3M 7100203719 Ceramic Fibre Disc 60 Grit 2 Inch

Product Description

The 3M 7100203719 is a 2-inch diameter ceramic fibre disc engineered for rapid stock removal on hard-to-grind metals. Built around 3M Precision Shaped Grain, it delivers higher cut rates and a cooler cut compared to conventional fibre discs. The disc runs at 60 grit and incorporates a grinding aid that limits heat buildup, making it well suited for heat-sensitive alloys. A stiff fibre backing and strong resin bond resist tearing under aggressive load. Fabricators, maintenance welders, and metal finishing professionals install this disc on angle grinders and disc grinders for heavy-duty surface work.

This disc is designed for weld removal, blending, beveling, edge chamfering, and finish refinement on stainless steel and high nickel alloys. The Precision Shaped Grain mineral is optimized for heavyweight applications where a conventional aluminium oxide or zirconia disc would wear prematurely. It is sold individually and is compatible with 3M disc pad face plates and hubs, which are sold separately. Typical use cases include fabrication shops, pressure vessel work, and structural steel finishing where surface integrity on corrosion-resistant alloys is critical.

Key Features

• Precision Shaped Ceramic Grain delivers higher cut rates and cooler grinding versus conventional fibre discs
• Grinding aid minimizes heat buildup, protecting heat-sensitive stainless steel and high nickel alloys
• 60 grit rating suited for aggressive weld grinding, beveling, and edge chamfering
• Stiff fibre backing with strong resin bond provides durability and tear resistance under heavy load
• Compatible with 3M disc pad face plates and hubs (sold separately)
• 2-inch diameter fits compact angle grinders used in tight-access weld zones

Compatibility

Compatible with 3M disc pad face plates and hubs sold separately. Designed for use on stainless steel and high nickel alloys in weld grinding, blending, and finish refinement applications.

Installation Notes

Fibre discs are installed by metalworkers and fabricators using angle grinders or disc grinders rated for the disc diameter and RPM. Always verify the grinder speed rating does not exceed the disc maximum RPM before mounting. Power down and disconnect the grinder from its power source before changing discs. Wear appropriate PPE including face shield and gloves when operating abrasive discs on metal.
