Drill Bit Drilling Rig Tools Casing Bit Three Wing Bit Hammer Bit
Hard Material
1. Our series anchor drilling tools include all kinds of drill
rods,casing,eccentric drill tool,concentric drilling tools and
hammers.
2. These products are reliable,they have stable performance and can
fulfill various drilling construction,such as DTH hammer,drilling
with casing and RC drilling,the products can suit the drilling in
crushed and complex formations.
3. The operations are very simple,remote operation can be
realized,these products can effectively reduce labor intensity and
auxiliary time.
4. These products can meet various construction requirements of
clients.Anchor drill rod is mainly suitable for DTH hammer.It
features large rigidity,good tightness,low torque and small
resistance.The drill rods have many specifications,such as 73mm and
89mm.
5. Among these tools,eccentric drill tools and casing are usually
matched with DTH hammer.The hammer has features of simple
structure,reliable operation,good performance and convenient
maintenance,it can match all kinds f anchor drill rods and casing.
Anchor drilling bit is an important of drilling,it is fixed at the
bottom of a casing or drill rod.This type of products includes
casing bit and three wing bit,hard alloy,clad sheet or diamond is
inlaid on the top.
This product makes the drilling easier,it has impressive efficiency
in digging operation,the drill bit rotates along with vertical
shaft and makes axial movement at the same time.
The soil is cut by the bits torque and axial force,the soil is
crushed by the extrusion force and centrifugal force of the blade
and forms earth flow pressing the wall of the pit,the earth flows
rises to the ground.
The screw on the anchor drill bit controls the rate of removal.low
spiral bits are used in the application where high cutting speeds.
Hard materials requires a larger point angle and softer materials
require a sharper angle.
The lenght of the anhor drill bit determines how deep a hole an be
drilled,it also determines the hardness of the bit and accuracy of
the finished hole.
The drilling bit is applicable to many fields,such as geological
disaster prevention and control,urban high building foundation
treatment and tunnel collapse.
