3M™ CUBITRON™ 3 Fibre Disc 1187C

3M™ Cubitron™ 3 Fibre Disc 1187C offers superior performance in medium to heavy-duty grinding applications, thanks to its innovative Precision-Shaped Grain technology and stiff fibre backing. This disc delivers a higher cut rate, increased durability, and longer life compared to other fibre discs, all while requiring less grinding pressure. It is specifically designed to improve productivity and reduce overall grinding costs when working with various metals, including stainless steel and heat-sensitive alloys.

With up to 56% more total material removal than the 3M™ Cubitron™ II Fibre Disc 987C, 36+, this disc ensures high stock removal and a fast cut rate across a broad range of applications. Its grinding aid minimizes heat build-up, making it ideal for heat-sensitive materials. Additionally, the 1187C helps lower hand-arm vibration exposure, increases throughput, and allows for more parts-per-disc, making it the optimal choice for demanding grinding operations.

Features

Re-engineered 3M Precision-Shaped Grain
The 1187C features re-engineered 3M Precision-Shaped Grain, which continuously fractures to maintain sharp cutting points. This ensures optimal performance and a longer lifespan, delivering 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+.

Durability and Tear Resistance
With a stiff fibre backing and strong resin bond, the 1187C is built to withstand heavy grinding applications. It offers durability and tear resistance, even under demanding conditions such as weld removal, bevelling, and medium to high-pressure grinding, including robotic operations.

Cool Cutting with Grinding Aid
The inclusion of a grinding aid helps maintain a cool cutting action, minimizing the risk of metal discoloration and stress cracks on heat-sensitive alloys. This feature ensures that the disc performs consistently while protecting the workpiece, particularly on stainless steel and non-ferrous metals.

Long-Lasting Sharp Performance
The 1187C’s sharp points remain effective throughout its lifespan, ensuring consistent cutting performance even under varying application pressures. This results in a longer-lasting disc, delivering sustained high performance without frequent changes.

Maximized Productivity
Designed to complete more parts per disc, the 1187C reduces abrasive waste and minimizes downtime from frequent disc changes. It enhances productivity in high-demand applications, improving overall efficiency.
