No matter what kinds of rock- Soft rock, loose-medium rock, hard rock and any other special formations, just tell us what you need and leave others at our disposal, We can also do according to customers' drawing or sample. So if you are interested in our products, please feel free to let us know. We also wish can do business with the people from all over the world.Features1. High-strength structure alloy steel and carbide.2. Transmit intensive impact energy into the rock with the least loss of energy.3. Longer service life.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-round application bit face specifically for medium hard and homogenerous 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 the load and wear on the gauge buttons, but poor hole deviation control.4. Double Gauge FaceThis kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.5. 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.SpecificationsThe technical parameter of Normal-type Thread button bits Thread Typediatip size(mm)flushing holesweight (kg)mmgaugefrontsidefrontR25 R28323*81*8110.3335*82*7210.3355*82*7210.4385*82*8210.5385*92*7210.5415*92*8210.6425*92*8210.6435*92*9210.6435*92*8210.6455*92*9210.7485*102*9210.78515*112*10211.1575*122*10211.3R32414*92*8110.54434*92*9110.55454*102*9110.6Thread Typediatip size(mm)flushing holesweight (kg)mmgaugefrontsidefrontT38575*113*10111.6645*123*11111.6765*143*12122.4T45706*114*10022.4766*134*10022.6898*125*12224.51028*136*122251158*146*13226.8T51898*125*12224.91028*136*12225.81158*146*13226.81278*146*14227.5
