Forging High Manganese Steel Dth Hammers, for Ore Mining, Machine Type : Drilling Tool

Listing ID #2101929

We offer dth hammers . Product name:hh series dth hammer
products features:
hhseries dth hammers are widely used in ground project for diving all kinds of mid-hardness,high-hardness and somehow worse drillability rocks,characteristics are as follows:
1hh low pressure dth hammers belong to air exhaust centre-valve hammers,which have a good effect in exhaust rock power,reduce re-breaks of rocks’power,and lessen the damage of drill to advance drilling efficiency.
2under 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.
3choosing the most high-quality raw material and most advanced technique,hammers have a more stable ability and longer servicing life.
4,more easilier in disassembly and assembly,lower trouble,more convinient in repairment.
Products scope:
boosting holes in mine,roads projects,drilling holes in protacting landslides and dams and so on.
