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 cutters 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!

Litian Raiseboring Drilling Tools Features

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.

Litian Raise Boring Cutters FAQs

Litian Raise Boring Cutters FAQs

What is the working principle of raise boring cutters ?

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.

What kind of machines can raise boring cutters be used to?

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.
