Black Diamond Cutters’ range of hard rock and EPB Disc Cutters have been developed in conjunction with major TBM contractors, manufacturers and designers, resulting in the consummate choice in Disc Cutters for contractors and TBM suppliers alike.

Black Diamond Cutters are made in Australia, and incorporate the latest bearing and sealing technology, coupled with state-of-the-art metallurgy and treatment processes. Black Diamond's unique design, which incorporates a single multi-rowed tapered bearing, coupled with a mechanical sealing system, offers significant benefits over current cutter designs available on the market today.

The "state-of-the-art" bearing assembly offers increased life and improved performance over current Disc Cutters, which results in substantial cost reductions in consumables per cubic metre.

Black Diamond Cutters' appreciate the importance of reliable sealing to maintain integrity of the bearing, therefore all Black Diamond cutters offer the best mechanical sealing system in the market today.

Our end caps are totally enclosed by the body of the cutter, which is specifically hardened to minimize the wear of the end caps due to wash out - effectively increasing the life of the cutter.

Black Diamond Cutters offer a full range of cutter types, complete with customized ring types and profiles to maximise efficiency and reduce costs in your project.

Black Diamond Cutters' appreciate that each project will have specific demands, and therefore we offer customised cutters to suit various housing and/or cutterhead configurations to meet your project's requirements.
