Features Hardening treatment of the part's surface with longer operating life and excellent anti-wear properties. Structural Optimization, improving the structural strength and ease of operation Superior Performance, high drilling speed with stable and reliable performance Application Range It is suitable for drilling water wells, geothermal wells, short micro piles,medium mini-type grouting hole of building, demand harbor project. Operation Procedure 1.when the drilling starts, the wings swing out, and reams to drive the casing shoes and tubes into the hole. 2.When finished the drilling in overburden rock formations, reverse the drilling tools and the wings will get closed, and the drilling tools can be raised from the hole. 3.Next construction can be followed.

Hot selling Factory Sale DHD350-135mm Button Mining Drill Bits DTH drilling is a percussion system driving a piston inside hammer body with up and down motion by compressed air and transmitting an intensive percussion energy to the bit to enable the drilling by crushing the rock. Drilling method by DTH hammer exerts high drilling performance especially for drilling hard rock and contributes for shortening work schedule. Hence, this method is widely utilized for foundation work, landslide prevention work, quarrying services, marine civil work, etc.
