12 Degress 38mm Short Skirt Tapered Button Bit For Small Hole Drilling
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
