Small Hole Drilling Tools Tapered Drill Bit Long Skirt Cross Bits For Mining Quarrying
Tapered Drill Bit Long Skirt Corss Bit For Mining Quarrying
The taper cross bits can be used under any rock drilling condition 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, which means carbides shape are cross type on drill bits. Taper cross bit is mainly used for hard or very hard rock formation.
Applications
• Underground mining
• Tunneling
• Quarry
Competitive Advantage
• High grade tungsten carbide inserts
• Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
Tapered Cross Bits:
1) Tapered connection: 7,11,12
2) Chisel bit diameter: 30-60mm
3) Technology:hot-pressing or welding
4) Bit Body: Short skirt and Long skirt
5) Tapered drill rod: H22/H25*108mm

NOTES:
To ensure the normal service life, the taper drill bits need to be matched well with taper drill rods, the taper degree must be the same between taper drill bits and taper dill rods; the penetration depth of taper drill rods which into the taper hole of taper dill bits should be over 25mm, and the head of the taper drill rods should not touch the bottom of the taper of taper drill bits, otherwise the taper drill bits would be lost easily during operation.
