Taper 12 Degree 34mm 38mm Button Bit Used In Drifting And Tunneling
Tapered equipment affords drillers the ability to change drilling
bits whilst still using the same drilling rod. Drillers choose
tapered cross type bits if the goal is to minimize hole deviation
in small hole range drilling. Different taper sizes have different
characteristics when it comes to the “knock-off” index – the
smaller angle will prevent the bit from spinning. Used in drifting
and tunneling.
Features:
1. Tapered button 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
Applications:
• Underground mining
• Dimensional Stone Industry
• Tunneling,quarrying
