Product Introduction
3M™ Cloth Cone 777F is a specialty abrasive designed for finishing hard-to-reach areas. Combining 3M Ceramic Abrasive Grain with aluminum oxide, it delivers fast, efficient cutting and long life. The cone shape allows precision work in corners and tight spaces, while its heat-resistant resin bond and grinding aid reduce heat buildup for cool operation on stainless steel, nickel alloys, and other heat-sensitive metals.
3M™ Cloth Cone 777F Features:
- Ceramic/aluminum oxide blend self-sharpens for sustained cutting performance
- Water-resistant polyester backing supports wet or dry use
- Heat-resistant resin bond ensures durability under high heat
- Grinding aid promotes cooler running on heat-sensitive metals
- Specialized cone shape provides access to confined spaces
3M™ Cloth Cone 777F Applications:
- Weld refinement in hard-to-reach areas
- Flash removal and machine mark cleanup
- Edge breaking and light polishing
- Finishing stainless steel and nickel alloys
- Die grinder operations in aerospace and metal fabrication
