Products Description
LEANOMS
QL60 Rock Drilling Hammer utilize double heat treatment for the hardening and tempering of all tool joints and adapters. Double heat treatment ensures optimum surface hardness and case depth. This allows us to achieve preferred hardness levels in the threaded areas. Toughness has been increased without compromising the exceedingly high wear resistance.
DTH Rock Drilling Tools Features:
1.The cylinders, pistons, and other spares is made of quality alloy steel with heat treatment.
2.More reliable,Valveless air distribution
3.Long life,Simple design of the piston
4.More efficient energy transfer, fact drilling speed, lower air consumption and lower oil consumption.
5.Fewer internal parts, simple structure, long life, less failure and easier to maintain because all the parts are heat treated.
6.Easy to disassemble because the top sub, the drive chuck and the external cylinder are connected by multi-step thread.
Rock Drilling Hammer without foot valve or with foot valve can be available.
Different out diameters of cylinder can be available.
DTH bits 60mm-1200mm for above hammers and bit can be available.
Along with being a trusted supplier to numerous prestigious mining companies and contractors around the world, LEANOMS is a top supplier in the tunnel construction sector.
Our mission:
Focus on drilling clients requirement and challenges, and continue to help them reduce drilling
costs and create greater productivity. Make the drilling works more successful.
