Featuring a heavyweight polyester backing, the sanding belt supports high-pressure applications and can also be used in wet or dry applications. With a grinding aid to reduce heat, the belt works well on heat-sensitive metals.

• 3M™ ceramic aluminium oxide grain blend surpasses aluminium oxide abrasives in cut-rate
• Durable ceramic/aluminium oxide blend extends belt life, producing more parts per belt and requiring fewer belt changes
• Heavyweight polyester backing supports high-pressure, tough applications and can be run wet or dry
• Contains a grinding aid to reduce heat and increase performance when used stainless steel and other exotic metals
• Durable resin bond protects from heat damage and extends the life of the belt

Commonly called sanding belts, abrasive belts are used with belt sanders for heavy-duty sanding applications. Belt sanders are used for smoothing certain surfaces or removing paint or varnish. They are suited to heavy-duty applications, or applications where a level of uniformity is required that can't be guaranteed by hand sanding techniques using conventional sandpaper.

This belt is particularly suited for use on stainless steel and metal allows for processes such as deburring and blending. They are commonly used for;
• Dimensioning parts
• Finishing casting
• Forgings

Belt sanders, or strip sanders, are typically portable handheld machines used for running across surfaces that need to be sanded. Wherever a large surface needs to be covered or a large amount of material needs to be removed, belt sanders can save a huge amount of time and physical effort compared to hand sanding. However, they are by design a powerful and aggressive machine, and the portable versions are not so suited to delicate work as other means of sanding.

Belt sanders can also be static backstand belt sander machines designed to have objects maneuvered against the sanding belt for finer sanding applications, This allows a greater degree of manipulative control, and is ideal for finishing and detail work.

3M is a leading innovator of abrasive technologies, constantly evolving to provide ideal solutions to industrial and commercial applications. With 3M you can be assured of a wide selection of quality products.

3M abrasive sanding belts come in a variety of widths and sizes to fit almost any industrial belt sander. Narrow belts are used with portable belt sanders for grinding or blending. Medium belts are used on backstands to remove wields, material removal and to set the grain in stainless steel while wider belts are used with wide belt sanders to dimension metal sheets and coils.
