3M 7100110344 Ceramic Fiber Disc 80 Grit 5 Inches

Product Description

The 3M 7100110344 is a 5-inch ceramic fiber disc rated at 80 grit for medium-grade material removal on metal, weld seams, and hard surfaces. Built on a resinoid bond with a fiber backing, it delivers consistent cut rate and durability under high-load grinding conditions. The disc spins up to 12,000 RPM and attaches via a threaded arbor hole sized at 5/8-11, making it compatible with 3M TN Quick Change backup pads. Licensed tradespeople in fabrication, metal finishing, and general industrial maintenance rely on this disc for aggressive stock removal without rapid breakdown.

This disc is suited for grinding and blending applications on ferrous and non-ferrous metals in both shop and field environments. The ceramic abrasive grain self-sharpens during use, maintaining cut rate over the life of the disc. The maroon color identifies the 982C series. Sold individually, with a minimum order quantity of 25 units per order.
