  1. What is the 3M™ Cloth Belt 341D used for?

    The 3M™ Cloth Belt 341D can be used for metalworking applications such as grinding, sanding and deburring.

  2. What does X-weight mean?

    X-weight refers to the weight of the cloth backing on a coated abrasive product. In this case, it means that it has a heavier and thicker backing which makes it more durable.

  3. What is Film-lok technology?

    Film-lok technology is where there are small spiral bands in the belt at regular intervals that help keep debris from clogging up the surface of the belt. This allows for longer-lasting performance and less maintenance compared to traditional belts without this feature.

  4. Is there only one grit available with this particular belt type?

    No, while its default stock configuration comes in 80-grit size (a medium level of abrasiveness), you can order other grit sizes depending on your application needs.

  5. How many belts come in one case?

    : Ten (10) belts come bundled per case so you'll have plenty on hand for large projects or ongoing production runs.

3M™ Cloth Belt 341D is a high-performance abrasive belt designed for aggressive dry sanding applications. The belt features fast-cutting aluminum oxide abrasive grains resin-bonded to a durable X-weight cotton cloth backing, providing continuous cut and long-life performance. Aluminum oxide mineral is a popular choice among industrial professionals due to its cut-rate, durability, and long life. It is commonly used in both woodworking and metalworking, including ferrous alloys. The abrasive particles are adhered to the cloth backing with resin, creating a strong bond that withstands high heat and pressure. The closed coat construction of the belt offers a consistent, fine finish, making it suitable for finishing on metal and producing a grain pattern. However, it should not be run wet. 3M offers a broad selection of abrasive belts to fit most any industrial belt sander. Belts come in many different widths and lengths and are used on a variety of different belt sanding tools for many different applications on both wood and metal. 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. Narrow belts are used with portable belt sanders for sanding or blending wood pieces such as cabinet doors. Belts come with various splices that join the belt ends. A film media splice achieves a secure bond with a joining film that minimizes chatter marks, ensures a smooth running belt, and produces consistent finishing results. A sine wave splice is constructed of interlocking fingers that enable the splice to travel smoothly over contact wheels, reduce hinging, and provide added strength to the joint area. Sine wave splices are typically used for coarser grades and wide belts.

Overall, 3M™ Cloth Belt 341D is a versatile and durable abrasive belt that can be used for a variety of applications in both woodworking and metalworking.
