Product Number 947A

The 3M™ Cubitron II Abrasive Belt 947A built with 3M™ Precision-Shaped Grain cuts metal dramatically faster and cooler, and stays sharp longer than conventional ceramic belts. Its X-weight poly-cotton backing is flexible. This belt is optimized for low and medium pressure applications on stainless steel, mild steels, and aluminum.

  • 3M Precision-Shaped Grain slices through metals like a knife rather than gouging or plowing
  • Removes material faster, with less pressure
  • Includes a grinding aid for less grinding friction and cooler cutting
  • Cool cutting action lessens the risk of heat-related damage to workpiece
  • An X-weight poly-cotton backing is optimized for flexibility
  • Lasts up to 4 times longer than conventional ceramic belts

  1. What is the 3M™ Cubitron™ ll Cloth Belt 947A?

    The 3M™ Cubitron™ ll Cloth Belt 947A is a high-performance sanding belt designed for use on various metals, including stainless steel and nickel alloys. Its unique abrasive grain technology allows it to cut faster and last longer than traditional sanding belts.

  2. What are the specifications of this belt?

    This particular variant of the Cubitron II Cloth Belt (947A) has a grit size of 60+, meaning it is suitable for medium to coarse sanding applications. It also features X-weight cloth backing, which makes it highly durable and resistant to tearing. The dimensions of this specific product are 3/4 inches wide by 20-1/2 inches long with a Fabri-Lok attachment system. Additionally, each case includes fifty single-flex belts per inner with a total of two hundred belts per case.

  3. Is this product easy to use?

    Yes! One significant advantage of using the Cubitron II Cloth Belt (947A) is that it can be easily installed onto compatible power tools such as grinders or belt sanders thanks to its typical Fabri-Lok attachment style. This ensures quick setup times without any cumbersome adjustments needed once you get started.

  4. How does this product benefit me as a customer?

    The exceptional quality and performance that comes along with choosing an abrasive tool from 3M will help increase overall productivity while reducing costs through extended longevity on your equipment life expectancy.Cubiton II is known for increased operator comfort during handling over other conventional abrasives due to fewer change overs being required ultimately enhancing worker health & safety.The revolutionary ceramic aluminium oxide mineral provides improved efficiency over traditional coated abrasives with reduced heat buildup resulting in cooler cutting temperatures allowing more work done within less time.Nothing beats having low downtime when working under strict deadlines, and that is what the 3M Cubitron II Cloth Belt can offer aside from being cost-effective overtime when properly maintained.

Fast and Flexible

A closed coat and a grinding aid make our 3M™ Cubitron II Abrasive Belt 947A an outstanding option for low to medium pressure applications on heat sensitive metals. The nature of the abrasive structure diverts heat to the swarf, keeping both belt and workpiece cooler. It is now available in grades 40+ (make to order), 60+, 80+ and now 120+ adding an improved solution for finer finishing applications.

Cutting Edge Performance for Low and Medium Pressure Sanding

A semi flexible Cubitron II belt the 3M™ 947A sports an X-weight poly-cotton backing. Among backing weights, an X-weight cloth is flexible and provides tensile strength as well. A great number of small belt sizes which are nimble and maneuverable so operators can get in, over and around intricate parts. These belts are good options for low-and-medium-pressure offhand operations for use on the following equipment:

  • Backstands
  • File Belt Sanders
  • Inline Sanders
  • Stroke Sanders
How 3M Precision-Shaped Grain Works

3M Precision-Shaped Grain is designed to continuously fracture to form sharp points and edges that easily "slice" through metal. It cuts faster, lasts longer and stays cooler. Conventional ceramic abrasive grain tends to "plow" through the metal, causing heat to build up in the workpiece and the abrasive – resulting in a slower cut, shorter belt life and undesirable effects, such as burnishing.

3M Science. The Beginning of Cubitron II.

In 2009, 3M scientists had long believed abrasives would work better if each grain of the ceramic abrasive material was exactly the same size and shape. It would act more like a knife shaving off material and less like a plow bouncing along the surface, creating heat damage. The breakthrough came when they realized they could use microreplication technology 3M was already using to create reflective material for signs, and other purposes. Within a short time, they had created 3M's Precision Shaped Grain — identical triangular-shaped abrasive grains electrostatically oriented and distributed uniformly on an abrasive backing. The end result is faster, cooler cutting action, improved productivity, less operator fatigue and longer belt life.
