Products Features:
1, Under the most-advanced drilling theory using in inside measurement design,hammers have more expected energy transmission,and let hammers have more power every single time,more speeder in drilling,less wind exhaust
2, Choosing the most high-quality raw material and most advanced technique,hammers have a more stable ability and longer servicing life.
3,choosing domestic most advanced hot-treatment technology to promise high mechanical properties.
4, Much easilier in disassembly and assembly,lower trouble,more convinient in repairment.

Products Scope:
diving all kinds of mid-hardness,high-hardness and somehow worse drillability
rocks(which depends on the type of hammers. )it is widely used in :boosting
holes in mine,roads projects,drilling holes in protacting landslides and dams
and so on.
