Product Details
  • Heavy weight fibre backing is tough and durable
  • Versatile disc can tackle many applications, from grinding to blending
  • Used with portable tools for easier access of workpiece
  • Closed-coat construction provides good grain density and durability
  • Resin bond withstands heat and stabilizes the disc under pressure and heat to increase productivity

Our 3M™ Fibre Disc 381C is a versatile and general purpose metalworking disc, designed to help with a variety of applications from grinding, weld removal & finishing to blending on common metals like carbon steel.

 

 

Altogether, fiber discs are durable abrasive discs that deliver a fast cut for grinding and weld removal, and they come in a range of sizes to correspond to large or small welds.
General purpose disc for weld removal, grinding and blending
Durable and Dependable
We engineer 3M™ Fibre Disc 381C by adhering aluminum oxide mineral to a fibre backing. The closed coat construction on 3M™ Fibre Disc 381C means mineral grains cover nearly 100% of the backing, so the abrasive is durable under pressure. The stiff fibre backing is extremely durable, withstanding wear, while standing up to tough applications like beveling.

Tips for Optimal Use
Altogether, fiber discs are durable abrasive discs that deliver a fast cut for grinding and weld removal, and they come in a range of sizes to correspond to large or small welds. Fiber discs also work well for blending (creating a smooth surface after weld removal) and provide a consistent finish over the workpiece. These discs may be used with portable tools, facilitating easier access with the workpiece. For optimal performance, the disc should be used with a face plate of the appropriate density for the application—a lighter density face plate for finer grade applications and a harder density face plate for more coarse grinding applications. Using the correct face plate for the application ensures that the abrasive mineral will re-sharpen, maximizing the life of the abrasive.
