Product description
In Top Hammer Drilling the hammer produces a percussive force on
the drill rods or tubes, which is transmitted to the drill bit. The
feed device is usually attached with a hinged boom to a mobile
unit. The percussive system strikes the drill rod, for example
2,000-5,000 strikes per minute, and the rotation speed can be, for
example, 60-200 rounds per minute. Together these elements make it
possible to drill holes in the hard rock. The excess material
(cuttings) is flushed up from the bottom of the hole by means of
pressurized air or water. Top hammer drills are primarily used in
mining, construction and quarrying of rock material. Top hammer
drilling, combined with the “drill and blast” method, makes the
whole excavation process extremely efficient.

Advantage
*Material are developed by cooperated with National & Local
Joint Engineering Laboratory for High-performance Metal Structure
Materials and Advanced Manufacturing Technology to improve the
fatigue resistance of drilling steel.
*Material is from Baosteel with strict process of steel smelting
and rolling: Refining - Vacuum - Continuous casting - drilling hole
method - surface peeling to control the content of non metallic
inclusion and harmful element.
*Strictly control precision thread process to avoid thread too hot
and broken effected by the high vibration and shaking of thread
part when it works.
*Heat treatment: Fully Carburization - Air cool quenching -
tempering. It make the rod keep high toughness and improve surface
harness and whole strength as well.
*Thread strengthen: enhance the thread parts to improve the
wear-resistance and longevity of the rod.
Application
