Advantages of dth hammer spare parts :
1.Valveless air distribution. More reliable.
2.Simple design of the piston, long life.
3.Fewer internal parts, simple structure, longer life, less failure and easier to maintain because all the parts are heat treated.
4.Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
