3M Cubitron II Fibre Disc 987C offers significant gains in productivity on on medium to heavy-duty operation with our exceptionally high-performing 3M Precision-Shaped Grain combined with a stiff fibre backing. The disc achieves a highter cut-rate, geatrer durability and longer life than other fibre discs - all with less grinding pressure. This allows for less operator fatigue, faster throughput, and more parts per disc when tackling high pressure grinding applications such as medium to heavy-duty stock removal. Features and Benefits 3M Precision-Shaped Grain maintains super-sharp points to help cut exceptionally fast and with less pressure Runs cooler and disc life is significantly longer allowing for more parts per disc and fewer disc changes Stiff fibre backing and strong resin bond provides durability and tear resistance Grinding Aid incorporated on the disc to minimise grinding temperatures for heat-sensitive alloys
