Black Diamond Cutters' range of hardrock and EPB disc cutters has been developed in conjunction with major TBM contractors, manufacturers and designers.

The cutters incorporate the latest bearing and seal technologies, coupled with modern metallurgy and heat treatment processes. Their unique design features a single multi-row tapered bearing that offers significant benefits for the user. This is complemented by a reliable mechanical sealing system that will maintain the integrity of the bearing over a long life. Black Diamond Cutters' end caps are totally enclosed by the body of the cutter, which is specifically hardened to minimize washout wear.

As a result, the Black Diamond Cutters' bearing assembly offers longer life and improved performance, which results in lower cost of consumables.

Black Diamond Cutters are available in a wide range of types and sizes ranging from 14” up to 17”. Also available are customized rings with profiles to suit a variety of housing and cutter head configurations. Technical data sheets may be obtained through our website.
