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.
- 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
