High and low air pressure down-the-hole drill bits 2. Low air pressure holeDia.: 65-220mm 3. High air pressure hole Dia.: 85-305mm 4. Face type: Drop center/concave/convex/double gauge/flat 5. Our DTH Bit can be suitable for many types of DTH Hammer, such as XL, Mission, COP, IR, Mach, Demag, SD, Bulroc, Halco Mach, Digger etc. 6. Inch available: 3", 4", 5", 6", 8", 12", etc... 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.FAQThe information you may like to know before order:1. Methods of Payment:  T/T (Telegraphic Transfer) or Western Union or L/C at sight2.
