PRODUCT FAQ

What is the main use of 3M™ Cloth Belt 777F, and why should I choose it?

The primary purpose of this cloth belt is to grind, blend, and finish ferrous metals. It can also be used on stainless steel or other high-nickel alloys. You should opt for this product if you are looking for a cloth belt that offers long abrasive durability while providing efficient grinding action.
What type of grain does this product use in its construction?

This cloth belt uses a Cubitron™ II Ceramic YF-Weight Grain that provides fast cut rates while maintaining consistency throughout its lifecycle.
Can I use it for wet applications?

Yes! 3M™ Cloth Belt 777F features an advanced resin system that increases heat resistance during low pressure wet conditions and keeps the abrasive sharp at all times during both dry and wet operations.
Is there any safety advice we should adhere to when using this belt?

As with any power tool products or accessories, always wear appropriate personal protective equipment (PPE) such as gloves and eye goggles before starting your work. Make sure to inspect the product frequently to check for signs of damage like burn marks or fraying which could lead to malfunctioning during operation
. What makes the ‘Film-lok’ feature so special?

. Film-lok functionality helps keep each disc secure because they lock together via friction instead of adhesives; thus reducing residues buildup between grits which tends to load up abrasives forces reduced performance over time

Deburr, Blend and Finish Stainless Steel

3M™ Cloth Belt 777F is a high-performance abrasive belt that is perfect for grinding, deburring, blending, and finishing stainless steel, nickel alloys, and cobalt alloys. This belt contains a grinding aid that reduces running temperatures when used on heat-sensitive alloys. The abrasive grain is bonded to the backing with resin to maintain durability under high heat and pressure.

Ceramic Abrasive Grain Boosts Performance

For increased performance, 777F products feature aluminum oxide blended with 3M ceramic abrasive grain for a harder, longer-lasting abrasive. The ceramic/aluminum oxide blend surpasses aluminum oxide abrasives in cut-rate and durability, making the Cloth Belt 777F an excellent choice for moderate stock removal and surface preparation.

Sized to Suit Your Needs

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.

Find Your Flex

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 full flex belt is the most flexible.
