KINGDRILLING DTH taper drill bit description:
The tapered
cross drill bit has strong comprehensive adaptability and can be used under any
rock drilling conditions. Compared with the tapered chisel drill
bit, the tapered cross drill bit has better drilling performance
because the carbide tip on the cross drill is doubled, that is, the
carbide is in the shape of a cross on the drill bit. Taper cross
drill bits are mainly used in hard or very hard rock formations
The tapered
cross drill bit is connected to the conical drill steel of the rock drill and is
used to drill holes. The tapered cross drill bit has strong
comprehensive adaptability and can be used under any rock drilling
conditions. Compared to tapered chisel drill bits, tapered cross
drill bits have better drilling performance because the carbide tip
on the cross drill bit is doubled, which means the carbide shape on
the drill bit is cross-shaped.

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:
A: Since KINGDRILLING factory sells directly to consumers without
the need of a distributor, it can provide you the best price.
3. How do I select the DTH drill bit's appropriate head face?
Concave: Excellent for perpendicularity of the hole and appropriate
for drilling deep wells in a variety of formations.
Convex: Good drilling efficiency, moderate borehole
perpendicularity, and appropriate for the development of strata
with a moderate degree of hardness.
Flat: This type of drilling is well suited for tough strata,
particularly those with fractures, adequate fracture spacing, and a
well-perpendicular borehole.
4. A feature of the product
Innovative electron-hydraulic forging hammers are used to forge
kingdrilling DTH tools, and multipurpose furnace heat treatment
controls the harness process.
