3M™ Cloth 777F uses a 3M™ Ceramic Aluminum Oxide Abrasives blend and is designed for light to moderate-pressure stock removal and finishing operations when you need a conformable belt for contoured surfaces. Our cloth is constructed with a blend of 3M™ Ceramic Abrasive Grain and premium aluminum oxide to give you more durability and cutting efficiency over non-ceramic abrasives.
3M™ Cloth 777F is constructed with a blend of 3M™ Ceramic Abrasive Grain and premium aluminum oxide to give you increased durability and cutting efficiency over non-ceramic abrasives. We back it with strong polyester cloth that can be run in a coolant environment or in a dry application.
Blended Ceramic Grain
3M™ Ceramic Abrasive Grain is a ceramic mineral designed using our proprietary process to enhance toughness and hardness of the grain. For increased performance, it features aluminum oxide blended with 3M Ceramic Grain for a harder, longer-lasting abrasive. Perfect for moderate to heavy stock removal, ceramic abrasives are engineered to cut fast and handle intense heat and stress applications. Ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability and makes 3M™ Cloth 777F an excellent choice for moderate stock removal and surface preparation.
Choose this cloth for use on stainless steel, cobalt chrome, titanium, and carbon steel for dimensioning parts, deburring, blending, and scratch refinement. To protect heat sensitive alloys such as stainless steel, nickel alloys and cobalt alloys from heat-related stress cracks and discoloration, we incorporated a grinding aid to help reduce grinding temperatures. Additionally, the abrasive is firmly bonded to the backing with resin to maintain durability under high heat and pressure.
