Tungsten carbide rock drill bits

Product Description

Rock drilling tools are tools used in rock drilling machinery, widely used in mining, railway and highway transportation, hydropower, and urban infrastructure construction.

Scope of use: Suitable for drilling soft and medium soft rock layers in industries such as geological exploration, coal mining, and civil engineering. Various mining and rock engineering projects.

Cemented carbide rock Drill Bits mainly including the following types:

K10 ,K20,K21 ,K30 ,K0, K1 types

The composition of carbide mining tool is mainly tungsten carbide and Cobalt, and its properties mainly include Cobalt content and larger and smaller tungsten carbide grain size to adjust. High Cobalt and coarse-grained carbide are selected for those that require good toughness and impact resistance require.

If the wear resistance is good, medium Cobalt and medium coarse WC grain alloys are selected.

Mining tools can be divided into: impact rock drilling tools, coal mining tools, geological drilling tools, there are five types of tools, including oil drill bits and stone processing tools. The main rock drilling methods for mining tools are: flushing Strike rock drilling, rotary rock drilling, and impact rotary rock drilling Mitsubishi.

Impact rock drilling mainly relies on the impact drilling of the drill bit, and the rock fractures under the impact effect Crushing and shearing, the drill bit mainly bears periodic impact loads.

Rotary rock drilling mainly relies on the cutting and drilling of the working edge. The rock is sheared under the action of axial thrust and rotational torque, and the drill bit is subjected to high compressive stress.

The impact rotary rock drilling is a combination of these two methods.

Due to the different properties of rock drilling (including soft and hard, cracks, gravel, density, and uneven hardness), different rock drilling methods, different rock drilling machine pressures, and different types of drill bits such as sheet and ball teeth, various types of mining are used

Tools have various requirements for the performance of hard alloys.

We need to select suitable alloy grades based on different rock drilling methods and working conditions. Impact rock drilling requires alloys with good toughness due to the impact load. If the rock hardness is high and the impact load is large, high Co and coarse should be selected grain based alloys. On the contrary, if the rock hardness is low and the impact load is small, medium cobalt and coarse-grained alloys should be selected.
