3M™ CUBITRON™ 3 Fibre Disc 1182C


The 3M™ Cubitron™ 3 Fibre Disc 1182C 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 fibre discs and depressed centre grinding wheels when grinding mild or carbon steels. Delivering up to 60% more total material removed compared to the 3M™ Cubitron™ II Fibre Disc 982C, 36+, this long-lasting fibre disc has a fast cut rate with high stock removal across a wide range of application pressures. 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.


This product 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 this product 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 this fibre disc, 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.




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 51% faster initial cut rate and up to 61% faster sustained cut rate compared to the 3M™ Cubitron™ II Fibre Disc 982C, 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

  • Requires less pressure to use, enabling predictable wear while helping to reduce metal discoloration and the risk of stress cracks on mild or carbon steels



  • 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


Ideal for heavy grinding applications:

  • Bevelling
  • Surface grinding
  • Flame cut smoothing
  • Weld grinding



  • Metal fabrication
  • Machinery manufacturing
  • Shipyards
