Application:
The taper drill bit is widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.
Product Feature:
We can design and manufacture according to customers' samples or drawings of the Bit Dia., No. of air/water holes, carbide button shape, and the face shape.
Our button bit is made with high-quality of best quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy.
Compared with tapered chisel bits and tapered cross bits, button bits have higher technology, much longer primary drilling time, and higher drilling efficiency.
According to the tungsten carbide insert, tapered button bits can be divided into the types of hemispherical, conical, and parabolic buttons, etc.
