3M 7100331745 Fiber Disc 60 Plus Grit 2 in Roloc 1187C

Product Description

The 3M 7100331745 is a 2-inch Roloc quick-change fiber disc engineered for aggressive material removal on metal and weld surfaces. Designated as the Cubitron 3 1187C, it uses precision-shaped ceramic grain technology to cut faster and last longer than conventional aluminum oxide discs. Rated at 60 Plus grit, it delivers a controlled cut on steel, stainless steel, and other hard metals without loading. The purple Roloc TR hub design allows for one-handed disc changes on compatible right-angle grinders and disc pads. Sold in quantities of 50 discs per carton, with 200 discs per case. This disc is intended for use by metalworkers, fabricators, welders, and maintenance trades.

The 1187C fiber disc is suited for weld blending, deburring, edge chamfering, and surface prep on ferrous and non-ferrous metals in fabrication shops, MRO environments, and industrial maintenance settings. The 2-inch diameter fits compact tooling configurations, making it practical for tight spaces and detail work on assemblies and structural components. The Die R200P designation corresponds to the disc's die-cut dimension and Roloc attachment format. Packaged for shop and field use, this product is commonly stocked for high-volume grinding operations.
