3M™ Cubitron™ 3 Fibre Disc 1187C, 36+, 4-1/2 in x 7/8 in, Die 450E, 10 ea/Case, Single Pack

The 3M™ Cubitron™ 3 Fibre Disc 1187C features re-engineered 3M Precision Shaped Grain — taking the legendary speed and life of 3M™ Cubitron™ Performance Abrasives to a whole new level. These product benefits include allowing for increased productivity and lower overall grinding costs vs. other fiber discs and depressed center grinding wheels when grinding a variety of metals, including stainless steel and other heat-sensitive alloys. Delivering up to 56% more total material removed compared to the 3M™ Cubitron™ II Fibre Disc 987C, 36+, this long-lasting fibre disc has a fast cut rate with high stock removal across a wide range of application pressures; it also features a grinding aid that minimizes temperatures for heat-sensitive alloys. Additionally, this disc is designed to help reduce exposure to hand-arm vibration, increase throughput, and complete more parts-per-disc when tackling medium to high-pressure grinding applications.

The 3M™ Cubitron™ 3 Fibre Disc 1187C plays a vital role in creating a robust and versatile abrasive solution, whether paired with 3M Angle Grinders for improved operator ease-of-use or incorporated into automated processes — such as robotic weld grinding. The performance advantages of the 3M™ Cubitron™ 3 Fibre Disc 1187C are tailored to enhancing and elevating automated weld grinding, including uptime, throughput, consistency, and efficiency. These four key elements are critical when optimizing your automated abrasive process, and with the 3M™ Cubitron™ 3 Fibre Disc 1187C, you'll experience increases in product life, cut rate, and wear consistency. These features can either enhance processes that are already automated or increase the appeal of automating currently-manual ones. To learn more, connect with 3M’s expert team of Robotic Abrasive Application Engineers — they are ready to partner with you on your automation journey, from idea to implementation.


  • RE-ENGINEERED 3M PRECISION-SHAPED GRAIN: Uses Re-Engineered Precision Shaped Grain, a proprietary technology designed with sharp, angular structures that continuously fracture to form sharp points to wear evenly, run cool, and optimize mineral breakdown
  • A WHOLE NEW CUT LEVEL: Delivers up to 53% faster initial cut rate and up to 43% faster sustained cut rate compared to the 3M™ Cubitron™ II Fibre Disc 987C, 36+
  • BUILT TOUGH: A stiff fiber backing and strong resin bond provide durability and tear resistance for heavy grinding applications, such as medium to high-pressure grinding, weld removal, and beveling — including robotic operations
  • COOL CUTTING: Features a grinding aid and requires less pressure to use, enabling predictable wear while helping to reduce metal discoloration and the risk of stress cracks on heat-sensitive alloys, such as stainless steel, and non-ferrous metals
  • LONG-LASTING: Maintains super-sharp points that cut exceptionally fast along the entire life of the fibre disc across a range of application pressures
  • STAY PRODUCTIVE: Designed to deliver more parts completed per disc while cutting down on abrasive waste, reducing changeouts or downtime
