Product Description
Tapered Tungsten Carbide Button Rock Drill Bit for Rock Drilling
Top quality taper chisel drill bits, taper cross bit, taper button bitclose to Atals Copco drill bit
Xiamen Bestlink quarrying tools can manufacture the following types according to clients need taper: 4, 6, 7, 11, 12 degree taper. The diameter for taper: 15, 19, 22, 25,, and diameter 26 28, 30, 32, 34, 36, 38 to 42(mm)
Furthermore, these products are manufactured in accordance with IS09001 stipulations.
We can design and manufacture drill bits according to customers' requirement of the bit diameter, number of air holes, carbide button shape and the face shape.
Our clients

A. Tapered chisel bits
The tapered chisel bit is widely used in drilling holes with depth less than
5 meters and diameter ranged in 20-45 mm by light-duty rock drill, like Y6
B. Tapered cross bits
The taper cross bits can be used under any rock drilling condition because of it's comprehensive adaptability. Compared with taper chisel bits, taper cross bits have a better drilling performance because carbide tips on cross bits doubled, which means carbides shape are cross type on drill bits. Taper cross bit is mainly used for hard or very hard rock formation.
C. Tapered button bits
Comparing with tapered chisel bits and tapered cross bits, button bits has higher technology, much longer primary drilling time and higher drilling efficiency, so that the button bit is popular among the users.
According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical button, conical button and parabolic button, etc.
Button bits with hemispherical button is for high bearing capacity and abrasive resistance while conical button and parabolic button are for high drilling speed and low abrasive resistance.
