Product Description

K0 Type Tungsten Carbide Drill Bits For Geological Prospecting And Coal Mining

 

 

K0 type tungsten carbide drill bits K40 customized for geological prospecting and coal mining

 

 

 

Advantages of Tungsten carbide drill bits:

 

1.High efficient in crushing

2.Low energy consumption

3.Long service life

4.Easy to replace

5.100% virgin raw material

6.Advance production equipment

7.With production experientce over 10 years

 

Application of drill bits:

 

1.Rock drilling

When drilling is started , it should be done with a little force with the air door slightly open and air door will be left wide open when the drill bit gets in 2-3 centimeters to increase the pressure for normal operations.The drill bits and the rods are to be replaced when they get in 1.5 meters of th shot holes .Normally 3 drilling rods are used with 3 drill bits replaced whe drilling highly friction rock formations.The diameter of the drill bits reduced  1-2mm successively. Deviations in the diameters of each group of drill bits should be minimized as much as possible,Drill bits with diameters differing much are to be used when the wear is signified . Each group of drill bits should get into the shot hole freely , since otherwise it will damage the inserts.

2.Repeated  regrinding

What wear fastest is the edges of the outer peripheries of the drill bits during rock drilling operations,When the working edges are 5-6mm from the outer peripheriess with a blunted width up to 3-3.5mm, or when inverted cones occur in the working portions , the drill bits have to be repeatedly reground. The repeated regrinding of the drill bits should keep the original geometries and the are to be checked with templates.

The reground drill bits should also be kept in a compatible package and the diameter of the drill bits should be checked making bright colored marks on the bits, making it easy for choosing the bits when they are to be used .In drilling soft rock formations , one drill bit can be used repeatedly until it reaches a status of bluntness that requires regrinding,The blunted drill bits should be repaired in time in order to avoid the reduction of drilling and unreasonable wear of the carbide.
