3M™ Fibre Disc, 381C, grade 24, 7 in x 7/8 in (177.8 mm x 22.2 mm) by 3M

The 3M™ Fibre Disc 381C is a versatile and general purpose metalworking disc, designed to help with a variety of applications from grinding, weld removal, and finishing to blending on common metals like carbon steel.The 3M Fibre Disc 381C was engineered 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. Altogether, fibre 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. Fibre 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 applicationa 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. When it comes to the 3M Fibre Disc Product offerings, choose the performance level suited to your unique project needs. The 3M Fibre Disc 381C offers an economical solution for a general-purpose metalworking disc, because it can perform well on a variety of projects without sacrificing performance. Given its versatility, you'll find the 3M Fibre Disc is applicable in many markets, as evidenced by its use in the marine and metalworking industries as well as in maintenance and repair operations.
