DTH Hammer Advatages
1.Valveless air distribution.More reliable.
2.Simple design of the piston.long life span.
3.More effcient energy transfer,faster drilling speed,lower air consumption and lower oil consumption.
4.Fewer intemal parts,simple structure,long life span,less failure and easier to maintain because all the parts are heat trated.
5.Easy to disassemble because the top sub,the drive chuck and the extemal cyinder are connected by muitiple steps thread.
