DTH drilling hammer suitable for water well drilling rig, rock drilling machine , it is provide power for drilling work, necessarydrilling tools Bit Face Shape Selection: 1. Drop Center BitFor high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.2. Concave FaceThe all-around application bit face specifically for medium hard and homogeneous rock formations.Good hole deviation control and good flushing capacity.3. Convex FaceFor high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce theload and wear on the gauge buttons, but poor hole deviation control.4. Flat Face BitThis kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.Carbide Button Shape Selection:1. Semi-Ballistic Buttons2. Ballistic Button3. Spherical Button4. Two-step ButtonOur Advantages:We have advanced production equipment & talented researchers & technicians & rich experiences in R & D and production.We using the best quality raw materials.We adopting advanced production technology & strict testing procedure.We passed ISO9001 quality management system certification.
