Tapered drilling tools

Advantages of JSI tapered drilling tools:
Made from material and advanced processing as same grade as internationally well-known brand, both ensure high quality of the tools
Specific design for different rock formation improves drilling speed and life-span
Entire CNC processing procedure ensure the consistency and reliability of quality
Military grade requirements of heat-treatment guarantee durability.

Tapered button bits It is the part directly working on the rock, the design and selection of specification directly affect the drilling speed and lifespan
Tapered chisel Bits It is the part directly working on the rock, the skirt material, tungsten carbide quality and brazing processing decide its life-span.
Tapered drill rods Transmit the impacting power and torque of rock drill to bit, the material, processing and heat-treatment are keys of life-span
