KINGDRILLING DTH taper drill bit description:
Tapered cross bits are fully adaptable and can be used in any drilling conditions. Taper cross bits have better drilling performance than taper chisel bits because the carbide tip on the cross bit is doubled, which means that the carbide shape on the bit is cruciform.
Taper cross drill bits can be used in any rock conditions and are mainly used in hard or very hard rock formations due to their comprehensive adaptability. Compared to tapered chisel drill bits, the carbide tip on the tapered cross bit is doubled for better drilling performance. Taper cross bit is mainly used for hard or very hard rock formation.

How to order
Tapered Drill Bits: Bit Diameter + Taper Degree + Socket Diameter.
Every drill bit is unique in size and design to maximize its use, accommodate a greater variety of drilling circumstances, and satisfy various project specifications.
  
  The taper bit and the taper drill pipe must fit perfectly and have the same taper in order to guarantee a regular service life.

FAQ:
1.What is the general delivery time?
15 working days for DTH bits.
20-25 working days for DTH hammer
3-5 working days for ex stock items.
2. Competitive pricing:
Because KINGDRILLING factory sells directly to clients without the need for a distributor, it can provide you the best price.
  
  3. How do I select the DTH drill bit's appropriate head face?
  a. Concave: Excellent hole perpendicularity, ideal for drilling deep wells in a variety of formations.
  b. Convex: Good for the development of strata with a moderate hardness; good drilling efficiency; moderate borehole perpendicularity.
  c. Flat: Excellent for unique hard formation strata, particularly for fracture, crack spacing, and complex formation drilling, with good borehole perpendicularity.
  
  4. A feature of the product
  Advanced electron-hydraulic forging hammers are used to forge kingdrilling DTH tools, and multipurpose furnace heat treatment controls the harness process.
