Our taper drilling tools include taper drill bits and taper drill
rod,and taper drill bits come into two types,taper button drill
bits,taper chisel drill bits.These drill tools are mainly equipped
on rock drilling equipment,well drilling equipment and oil field
equipment.They are widely used for rock drilling,blasting holes and
other drill works in quarries,coal mines,rod and dam constructions
and other similar projects.
Description:
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.
Made with high quality of raw material through special heat
treatment ,especially, tungsten carbide of tapered button bits are
from Boart long year,widely applied in Hand Hold ( short-hole)
drilling system for dimensional stone quarrying. At now, we are
exporting the huge qty of Q7- 33- 7 22-80 , Q9 -45 -12 22- 71 for
Indian quarry and Norway, Finland quarry.
Diameter of bits from 30mm to 50mm with 4 ,6,7,11,12 degree,
premium alloy tapered drill steel with Hexagonal.22mm and
Hexagonal.25mm,The deliver capacity are very strong and can
completely meet customer's requirements on delivery design,number
of buttons is 4,5,6,7,8,9,7 buttons is very popular for hold held
(short holes ) and blast drilling system.
