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.
Diameter: φ28 φ32 φ34 φ36 φ38 φ40 φ42
Process: Forging,Heat treatment ,Inlay carbide
Material: 42CrMo,23Crni3mo etc.
Connection method:Tapered or Thread
Body type: long skirt and short skirt.
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
