Share to:

Cross Drill Bits are made from grade hard alloy and special steel, generally matched with the light-duty rock drill, to dtill the rock hole within diameter of 50m. The mining drill tools are used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.

  • 22x82mm, 22x108mm, 25x108mm, 25x159mm
  • Tungsten carbide and high strength alloy steel

Cross bit is used under any rock drilling condition and mainly used for hard or very hard rock formation 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.

Feature of Tapered Rock Drill Cross Bit:

1.tapered cross bits connect with tapered drill rod for drilling holes

2.Stale and mature welding technology ensure good quality of bits

3.Accurate dimension of taper degree perfectly matches the rods

4.work reliable and very cost-effective

Application

1.The cross bit is suitable for digging of very hard rock formation, hard formation and crack-grown formation.
2.All cross bits have to be reground at regular intervals to crush rock efficiently.

3.We choose different material and size for the cross bits in order to adapt the different rock formations and working conditions.
