KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes.

How to order the products? A: Please send the inquiry with detail item description or with Model number.  2. Can I expect a quality products? A: Yes. mature production technology ensuring the quality satisfy international request.  3. How to control quality? A: We have our own experienced QC team,there will be strict inspection and testing for each order before shipping out.  4. Competitive price: A: KINGDRILLING factory can supply you the lowest price due to direct sale to customers without distributor.  5. What is the Application? Mining, Quarrying, Tunneling, Construction, Geological Exploration, Water-well Drilling, Oilfield & Gas Industries.  6. Product feature Kingdrilling DTH tools are forged by advanced electron-hydraulic forging hammer, and harness process is managed by multipurpose furnace heat treatment.  7. How to choose the suitable head face of the DTH drill bit? a. Concave: Suitable for all kinds of formation, especially for deep well drilling, perpendicularity of the hole is wonderful. b. Convex: Suitable for the formation of moderate hardness stratum, drilling efficiency is good, borehole perpendicularity is moderate. c. Flat: Suitable for special hard formation stratum, especially for fracture, crack spacing and complex formation drilling effect is very good, has the good perpendicularity of the borehole.
