Description

Cloth Belt 777F protects against heat-sensitive alloys such as stainless steel, nickel alloys, and cobalt alloys with a grinding aid that lowers running temperatures, and the abrasive is resin-bonded to the backing for durability under high heat and pressure. This belt is recommended for dimensioning parts, deburring, blending, and finishing castings and forgings made of stainless steel or other exotic metal alloys. Ceramic abrasives are designed to cut quickly and withstand high heat and stress, making them ideal for moderate to heavy stock removal. The Cloth Belt 777F's ceramic/aluminum oxide blend outperforms aluminum oxide abrasives in cut-rate and durability, making it an excellent choice for moderate stock removal and surface preparation.

Key Features:

It comes in a variety of widths and lengths and can be used to sand both wood and metal.
It has a film splice for added strength when grinding under high pressure.

Contains grinding aid which enhances performance on stainless steel and other exotic alloys 3M™ Cloth Belt 777F protects against heat sensitive alloys like stainless steel, nickel alloys and cobalt alloys with a grinding aid that reduces running temperatures, and the abrasive is bonded to the backing with resin to maintain durability under high heat and pressure. This belt is recommended for use on stainless steel or other exotic metal alloys for dimensioning parts, deburring, blending, and finishing castings and forgings. Proprietary 3M™ Ceramic Abrasive Grain is a ceramic mineral designed to enhance toughness and hardness of the grain. For increased performance, 777F products feature aluminum oxide blended with 3M ceramic abrasive 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 the Cloth Belt 777F an excellent choice for moderate stock removal and surface preparation. These abrasive belts are available in various widths and lengths for sanding both wood and metal. 3M offers a broad selection of belts to fit most any industrial belt sander. Wider belts are used with wide belt sanders to dimension or finish wood panels, smooth rough cut edges of metal sheets, or add a grain pattern to stainless steel sheets. Medium-width belts fit onto edge sanders for sanding flat, narrow surfaces such as panel edges; and narrow belts are used with portable belt sanders for sanding or blending wood pieces such as cabinet doors. Belts come with various flexibilities and splices that join the belt ends. 3M™ Cloth Belt 777F has a film splice for added strength when grinding in high pressure applications. When greater flexibility may be needed to increase conformity or for a softer touch for finishing and blending, an L-flex provides more flexibility than the standard flex, and a fullflex belt is the most flexible.
