Blue Tungsten Carbide Buttons , Tipped Tapered Drill Bits For Rock
Drilling
Product Characteristic:
1 .Button bit taper angle: 7°,11°,12°
2. Length: 50/55/71/80 mm
3. Diameter: 20-45 mm
4. Button bit shape: spherical/ballistic/conical
5. Socket inside diameter: 15/19/22/25(mm)
6. Material and process: high quality alloy steel bar and tungsten
carbides, through heat treatment
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.
Comparing with tapered chisel bits and tapered cross bits, button
bits has 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 andparabolic
button, etc.
