Raise boring cutter (RBM cutter) is a tungsten carbide insert roller cutter mounted on the reaming head of raise boring machine (RBR, raise borer), which is an excavation tool for breaking rocks. As the most important raiseboring drilling tools, the raise boring cutters are mainly used in the construction of vertical shafts, inclined shafts, surge shafts, ventilation shafts, and escape shafts, and can be widely applied in underground engineering construction fields such as mine, hydropower, transportation and so on.
Litian Heavy Industry is a leading manufacturer of high-performance raiseboring drilling tools. Our premium raise-boring roll cutters (also known as roller cutters) are engineered to withstand the most challenging geological conditions in mining and civil engineering. By integrating advanced metallurgy with precision engineering, our tools ensure higher penetration rates and longer service life for your reaming operations.
We offer a comprehensive range of raiseboring tools tailored for different rock formations.
Kerf Type Raise Boring Roller Cutter: Ideal for hard rock excavation, providing excellent chipping efficiency and reduced torque requirements.
Random Type Raise Boring Roller Cutter: Best suited for soft to medium-hard strata, ensuring full-face coverage and consistent rock-breaking performance.
Whether you need a standard or customized raise boring roller cutter, Litian provides the durability required for deep shaft drilling.

The insert buttons of raise boring cutters adopt high-quality tungsten carbide with good wear resistance and long service life, and the commonly tungsten carbide insert design includes chisel inserts, conical inserts, spherical inserts, which can be used with raise boring cutters to improve drilling efficiency under different geological conditions.
The raise boring cutter hub uses high-quality raw materials and reasonable design, and it can meet long-distance use under different geological conditions.
The metal seal of our raise boring roller cutters has excellent high-temperature resistance, reliable sealing performance, and can meet long-distance use in harsh working environments.
The raise boring cutter bearing has good wear resistance and deformation resistance, and good overall performance. Our optional bearings include tapered roller bearings, ball bearings, and thrust roller bearings.
Litian raise boring roller cutters have been practically applied under a variety of different rock conditions, and the rock roller cutter body structures and the button spacing are optimized according to the different rock performance characteristics. Our raise boring cutter drilling tools can be applied to the excavation of different hardness strata (30Mpa~300Mpa), such as sandstone, limestone, granite, basalt, etc., and can meet different engineering needs.
We use scientific calculation and analysis methods to accurately calculate the maximum cutting efficiency and movement direction of each cutter row so that each alloy button can produce the maximum breaking area and volume when it contacts the hole wall. Litian raises boring cutters have strong wear resistance, stable performance, durability, and can cooperate with raise boring rigs for efficient rock-breaking operations, thereby helping users shorten construction time, improve drilling efficiency, and reduce engineering costs.
The working principle of the raise drilling cutters is that the raise drilling rig applies drilling pressure and torque to all the roller cutters on the cutter head to make the cutters penetrate the rock. Every raise boring cutter rotates around its own axis and rotates around the central axis of the cutter head, so as to continuously squeeze and roll the rock mass surface, break the rock mass and form a drilling borehole.
Litian raise boring cutters can be used on Raise Boring Rig (RBR), Boxhole Boring Machine (BBM), Boxhole Backreaming Machine (BBR), Reef Boring Machine (RBM), Shaft Boring Machine, Reverse Circulation Rig...， with a cutter head diameter ranging from 0.3m-8m.
Our raise boring cutters feature premium tungsten carbide inserts and a high-load bearing system to maximize penetration rates in hard rock. We focus on reducing downtime through advanced metallurgy and superior seal reliability.
