IR380 DTH HAMMER

IR380 - 4 1/2" Pin RH - 8" DTH Hammer Epiroc DTH Hammer for Blast hole drilling

Down-the-hole hammers
Roschen DTH hammers combine intensive impact power with low energy loss and reduced fuel consumption. They offer good rock breakage, high penetration rates, long service life and optimized productivity.

Reduced operating costs
Roschen DTH hammer designs offer high power and air efficiency, reducing operating costs and carbon dioxide emissions from drill rigs.

Tailored and versatile products
These hammers work with various industry-standard shanks and a wide range of standard-size hammers. Roschen's DTH hammer product offering covers all applications and mining conditions.

Easy service
Straightforward maintenance helps reduce machine downtime, further enhancing your productivity.

18bar - 26m3/min
24bar - 35m3/min

Structure Feature:

1. Standard API Thread
2. Top sub with cement carbide button (Alternative)
3. Internal parts are highly assembled to avoid interactive wear and hammer's reliablity is increased.
4. Piston case: Using superior alloy steel, even better reliability and longer life after heat treatment.
5. Hammer front structure design: when pulling out the hammer, the last impact of the piston would fall on the step of piston case, ensuring the safety of the driver sub splines and the retainer ring.

In order to increase the working life of the piston case when drilling every abrasive rock, the driver sub is designed to be made up of three pieces and only the wear-proof casing needs to be replaced timely.

Heat treated piston and internal cylinder guiding system are reasonably structured to achieve the highest efficiency and the largest impacting power. The penetration speed is 10%-30% faster than other products of the same type.

ROSCHEN optimized structure design: Fewer air holes on the internal cylinder, highest stiffness of air slot.

The multiple threads are CNC machined to achieve high accuracy, making the bit easy and smooth to get assembled. Driver sub is heat treated to achieve better abrasiveness and longer life.
