Top hammer drilling tools presents that the high-frequency piston strikes on the shank adapter generate significant impact energy, which is transmitted as stress waves through the rods to the drill bits, effectively breaking rock. This system achieves high energy densities of 200-400 J per impact while simultaneously completing rotary cutting. It has the advantages of strong penetration and large single rock-breaking volumes in hard rock, making them adaptable to complex working conditions in underground mining, open-pit operations, construction, and more.

JSI offers the whole top hammer drilling string encompassing drilling bits, rods, shanks and couplings, which stably achieves high working efficiency and sustainable productivity in various drilling applications from soft to extremely rock conditions.

DTH (Down the Hole) drilling tools represent a high-efficiency solution for medium and large diameter rock breaking. It places the power unit deep within the hole, allowing the axial vibrations of the piston in the hammer to convert compressed air directly into impact energy at the drill bit. This "percussion-rotation" method minimizes energy loss and achieves high straightness and smoothness in the drilled holes, resulting in exceptional rock-breaking efficiency.

DTH tools do not rely on high axial thrust and have no limitation on the drilling depth. Featuring convenient maintenance, DTH has now become the mainstream rock drilling solution in open-pit mining, metal vein exploration, highway and railway construction, water conservancy and hydro-power projects, and geothermal wells construction, etc. It is especially suitable for the high-precision and deep-hole operation of complex geological formations.

JSI offers a complete range of DTH drilling tools including hammers, bits, pipes, adapters, providing competitive solutions for customer’s needs in various drilling and blasting applications in mining, construction and water well industries.

Blast furnace tapping tools are crafted from premium steel and alloys, ensuring superior quality. Engineered with fluid mechanics-designed bits, these tools offer faster feed speeds and enhanced hole-forming quality. They utilize a combination of mechanical, hydraulic, or electric drive systems, where the bit is driven by high-speed pneumatic, hydraulic, or electric motors to complete the drilling process efficiently.

Tricone bit is one of the main tools for blast hole drilling in mining and water well drilling. It connects with drill pipe and rotate along with it, drive cones to press on the rock. The tungsten carbide inserts or steel teeth on cone shell cause the formation to spall under the drill weight and the impact load from cone rotation, the cuttings will be discharged out of hole by compression air or with agent such as foam. A suitable design has great influence on the drilling speed, lifespan and working efficiency of the site.

Steel tubes can be used as raw materials for the further processing of various products, such as blast furnace drill rods, self-drilling anchors, and others.
