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.
