Description
Product descriptionCompatible with the bits of cop/DHD series.Simple piston structure increases it's life time Adopt valveless air distribution.simple structure makes it easy for dis-assembly.with faster drilling speed and less power consumption.when required to increase deslagging,holes can be added on reverse valve.Adopt fine alloy steel and apply hardening treatment on the spare parts.which prolongs DTH hammer lifetime and lifts reliability.DTH Hammer has a wide range of use in all kinds of hard and abrasive rocks.
follwing features:
1,DTH hammers are used for blast hole drilling and blasting, mainly applied in Mining,
2,Marble quarry or well drilling and other construction projects.
3,New products designed based on mining condition in china, improving by advanced technology from global market.
4,Superior materials, advanced process,guaranteed quality.
5,Faster drillinq rate.
6,Hardness can be enhaced to expand the lifespan of hammer, and lower the cost.
7,Huge impulse with low consumption of electricity.
8,The modern theory is adopted in the structural design, which makes the stress.
9,wave duration longer, the stress amplitudeis lower, and the piston life is long.
