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.

Customization Service Support

We support personalized customized ST58 reaming bits according to customers' special engineering needs. Whether adjusting diameter specifications, optimizing carbide configuration, or upgrading structural parameters for special rock formations, we provide one stop customized solutions to meet diverse construction requirements.
