Raise Boring Cutters

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 focuses on developing and manufacturing raise boring roller cutter suitable for all kinds of raise boring rigs and rock formations and can provide users with comprehensive technical support and consultation, as well as various forms of services and solutions.

Different Types Of Litian Raise Boring Roller Cutters
Litian raise boring cutters are designed and manufactured for all sizes of reaming heads. These rock roller bit cutters are used for different types of drilling from horizontal drilling, blind drilling to vertical drilling, etc. Different types of raise boring drilling tools have different advantages. Our kerf roller cutters are designed to achieve the best performance in all rock formations by varying spacing between rows of tungsten carbide inserts. Our random cutters, also known as RCD cutters, can be randomly arranged with optimal inserts to achieve better penetration and higher toughness, based on specific rock formation information. Litian raise boring cutters are designed and manufactured using the latest technology to provide optimum performance. Click below to get more！

High-quality Raise boring Roller Cutter Parts

Buttons
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.

Hub
The raise boring cutter hub uses high-quality raw materials and reasonable design, and it can meet long-distance use under different geological conditions.

Sealing
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.

Bearing
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 Raiseboring Drilling Tools Features

Litian raiseboring tools 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 to have strong wear resistance, stable performance, and 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.

Litian Rock Tools, as an excellent drilling tools factory, offers a wide range of rock drilling tools for you to choose from.
