  • taper button bit
  • Kingkong Drills
  • taper button bit
  • tapered bit
  • 6°, 7°, 11°, 12°
  • secondary crushing, anchor rod support, tunneling
  • Hex22, Hex25, Hex19
  • High quality carbide and steel

Taper Button Bits with higher strength of tungsten carbide as the body, the bit has good anti-erosive and the increased the toughness. the taper drill bit has enhanced reliability and drilling efficiency. Suitable formation:Medium hard to hard, solid hard rock formations.
