Frequently Asked Questions

What are 3M 982C fiber discs used for?

3M 982C fiber discs are cool-cutting abrasives for carbon steel and soft metals. They remove material quickly with less heat buildup, reducing discoloration and warping. Ideal for weld blending, deburring, and surface finishing in metal fabrication and maintenance.

What are the specifications of 3M 982C fiber discs 4 x 7/8?

These 3M 982C fiber discs are 4 inches in diameter with a 7/8-inch unthreaded arbor hole. They feature ceramic grain in 36 grit, packaged 25 per box. The MPN is 7100208163. They are designed for aggressive grinding on carbon steel and soft metals.

Where to buy 3M 982C fiber discs worldwide?

3G Electric supplies 3M 982C fiber discs worldwide. We handle full logistics and customs clearance to deliver these 4-inch ceramic discs to your facility. Contact us for pricing and lead time on this 25-pack item.

How to select the right grit for 3M fiber discs?

For heavy stock removal on carbon steel, choose 36 grit like these 3M 982C discs. Finer grits (60-120) are for blending and finishing. Match the disc diameter and arbor hole (4 x 7/8 inch unthreaded) to your backing pad. Always test on scrap material first.
