Product Specifications
Specification Details
Thread Standard ST58 industry standard thread for tight compatibility with matched drilling rigs and drill rods
Applicable Diameter Range 137mm to 204mm, covering most conventional roadway and mining borehole reaming requirements
Carbide Material ZCC YK05 high hardness tungsten carbide with 9*16mm specification, featuring exceptional rock breaking ability and abrasion resistance
Steel Body Material 50R61 high strength steel grade, consistent with Epiroc's mainstream material standards, with excellent impact resistance and structural toughness
Core Advantages
Exceptional Durability Extended Service Life
The whole bit body is forged from high quality 50R61 steel and paired with ZCC YK05 premium carbide buttons. The integrated structure avoids loose parts and structural damage caused by long term high intensity rock impact, significantly upgrading wear resistance and anti impact performance.
Integrated Structure Low Maintenance
Designed as an all in one structure, this ST58 reaming bit requires no pre assembly before use. It can be directly installed and put into operation, simplifying on site procedures and reducing daily maintenance difficulty.
Ultra Stable Operation High Reaming Precision
The optimized integrated structural design effectively suppresses vibration and jitter during high speed hole expansion, maintaining stable operation in complex rock formations and ensuring uniform borehole diameter.

Application Scenarios Working Principle
This ST58 rock reaming bit is widely applicable to roadway excavation, mining rock drilling, tunnel construction and other engineering scenarios. The standard working process involves :
  • First, use a guide drill bit to drill accurate and straight pilot holes to fix the drilling trajectory
  • Then, install the ST58 thread reaming rock bit for secondary hole expansion treatment
  • This two step process quickly enlarges the pilot hole to the target construction diameter
This drilling and reaming process ensures straightness and regularity of the borehole while greatly improving drilling efficiency for batch and large scale rock drilling projects.
