Product Description
DTH hammers are used for blast hole drilling and water well drilling project. Working with DTH drilling pipe and DTH drill bit, mainly applied in Mining, Marble quarry or well drilling and other construction projects.
Down-the-hole rock tools (drilling tools) are rock drilling equipment which takes compressed air as power
source to partially transfer impact power into drilling holes. An air distributing device in a top hammer controls a piston to move back and forth.
With professional manufacturing experience in DTH hammer production, our factory can supply you with high pressure and medium to low pressure DTH hammers. It strictly matches with API standard and other Chinese industry standards.It is durable for being produced with advanced craft work and good material.
