Taper button bit as small hole bit is different with thread button bit as long hole bit to use taper match with bit with rod to be used for air leg or hand held jack hammer driller in quarrying,and mining.
Made with high quality of raw material through special heat treatment, especially, tungsten carbide of tapered button bits T6 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.
