Product Introduction

This series of drilling tools are universal rock reaming tools for the trenchless industry. Our company independently designs and produces roller blades and can produce various types of roller reamers suitable for trenchless drilling rigs and various strata.

According to the characteristics of the drilling rig and different formation conditions, choose the appropriate tooth type and bearing structure. The palm tip is widened and thickened with alloy, and the palm back is inlaid with anti-wear alloy to reduce wear. Hydraulic rock breaking. Slag discharge is smooth to reduce rock slag accumulation. Welding process to prevent welding overheating.
The drill body guide belt design has a good guiding effect, which allows the reamer to contact the well wall smoothly. Reasonable design of the drill body guide belt has a good guiding effect, which allows the reamer to contact the well wall smoothly and reduces the tendency of the pipeline trajectory to change line.
