Our hard-rock cutting tools are designed for extreme geological conditions, suitable for rock formations with a uniaxial compressive strength exceeding 40 MPa.
The product range includes hobs, steel tool rings, and insert rings, developed in collaboration with Central South University and the University of Science and Technology Beijing.
Through advanced vacuum heat-treatment technology, these tools deliver superior hardness, strength, and cutting precision, making them ideal for underground mining and tunneling in ultra-hard rock formations.
