H25 35mm Cross Bit Wear-Resistant Thread Drill Bit for Mining and Hole Drilling

Product Description:

Carbides shapes are cross type on drill bits, the same as taper chisel bits, they have different taper degree and diameters. Meanwhile cross bits are Usually all carbide tips, including chisel, cross or button types, before carbides run out, carbides can be grind to be sharper when carbides are wear out.Drill bit body is made of high quality steel imports; the head is made of special alloy through special welding processing. Drill bit is widely used in all kinds of mining engineering and rock engineering.

The cross rock bit can be used under any rock drilling condition, it's hardly impacted by the model of drill rig and the rock performance. Generally, chisel bit is mainly used for hard rock, cross bit and button bit are mainly used for fissural rock.

It is mainly used for diging into mine laneway and blasting holes in all drilling works matched with the taper drill rod. For different rock, we choose the different alloy to extend the working life of the drill bits.

1. Made from high alloy steel and YK05 tungsten carbide as same grade as internationally well-known brand

2. Apply "hot (thermal) -insertion" processing procedure to insert the buttons as same as internationally well-known brand

3. Entire CNC processing procedure ensure the quality consistency

4. Military grade requirements of heat-treatment guarantee durability

5. Fast penetration rates, and straight and clean hole quality. Long life of drilling holes.

Products Parameters:

We can design and manufature according to your requirment of diameter, number air holes and carbide button shape

Product Advantage:

Made in China R25/R28/R32 thread Cross Carbide Bit

Our cross bits diameters are from38mmto127mm, and different type are available, like R22,R25, R32, R38, T38,T45,T51,ST58, ST68,etc

Feature:

1. Excellent drilling penetration

2. Used in very hard or hardest rock formation

3. Adequate for various construction conditions

4. Strong corrosion resistance

Application:

1. The cross bit is suitable for digging of very hard rock formation, hard formation and crack-grown formation.

2. All cross bits have to be reground at regular intervals to crush rock efficiently.

3. We choose different material and size for the cross bits in order to adapt the different rock formations and working conditions.
