KINGDRILLING DTH taper drill bit description:
To accomplish drilling operations through the taper connection on
the drill bit and drill pipe, the tapered button drill bit is
mostly utilized in conjunction with a pneumatic rock drill and a
tapered drill pipe. Cone drill bits are mostly utilized in
secondary crushing, drifting, anchoring, and other fields in mines.
They are excellent for drilling hard rock. The cross and chisel
drill bits were updated to create the taper drill bit. The drill
bit has a long service life and good performance since it uses a
hot-dip skirt and tungsten carbide bit. Twelve, eleven, and seven
degrees are the standard taper angles for tapered drill bits.
Our company offers small hole rock drill bits:
Tapered Drill Bit is different with thread button bit as long hole bit to use taper
match with bit rod to be used for air leg or hand held jack hammerdriller in stone quarrying, and mineral.

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 price:
A:KINGDRILLING factory can supply you the lowest price due to
direct sale to customers without distributor.
3. 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.
4. Product feature
Kingdrilling DTH tools are forged by advanced electron-hydraulic
forging hammer, and harness process is managed by multipurpose
furnace heat treatment.
