3M Cloth Roll 777F combines 3M ceramic/aluminum oxide abrasive grain, a resilient resin bond and a grinding aid with a durable polyester cloth backing to stand up to different grinding pressures on heat-sensitive metals. The polyester backing can run either in a wet or dry grinding application.

Rugged, Dependable, Exceptional
One of 3M's best cloth-backed abrasives for stainless steels, aluminum, steel and fiberglass, 3M Cloth Roll 777F is constructed with 3M Ceramic Abrasive Grain, a high-performance grain we've blended with aluminum oxide to form one of the hardest, longest-lasting abrasives available. It cuts fast and delivers exceptional results.

The Coolest Way to Handle Metal
We back it up with a strong but durable YF-weight polyester cloth backing. It's water resistant for use with coolant; that keeps surfaces cooler during use and helps to washe away grinding debris. To further protect heat sensitive alloys like stainless steel, nickel alloys and cobalt alloys from heat-related stress cracks and discoloration, we incorporated a grinding aid to help reduce grinding temperatures.

In economical, convenient roll form, this abrasive is easily cut to size for any grinding or finishing application.

Recommended Applications
3M 777F is commonly used on stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings.
