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.
