A DTH Hammer is a percussive rock drilling tool. Unlike other drilling tools, it remains at the bottom of the hole throughout the operation, breaking rock by directly striking the drill bit. Compressed air travels down the drill pipe into the hammer and is then exhausted through the bit. This exhaust air is utilized to flush cuttings from the hole. The rotary motion is supplied by the drill head, while the feed force (or thrust) is provided by the feed system and transmitted to the hammer via the drill pipe.


DTH hammers are used for blast hole drilling and blasting, mainly applied in Mining, Marble quarry or well drilling and other construction projects.


Main Feature:

New products designed based on mining condition in china, improving by advanced technology from global market.

Superior materials, advanced process,guaranteed quality.

Faster drillinq rate.

Hardness can be enhaced to expand the lifespan of hammer, and lower the cost. Huge impulse with low consumption of electricity.

The modern theory is adopted in the structural design, which makes the stress.

wave duration longer, the stress amplitudeis lower, and the piston life is long.
