11degree Tungsten Carbide Mining Drill Tapered Cross Bit
Feature of taper button bit
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
Tapered equipment affords drillers the ability to change drilling
bits whilst still using the same drilling rod. Drillers choose
tapered button bits for faster drilling penetration rate. Different
taper sizes have different characteristics when it comes to the
“knock-off” index – the smaller angle will prevent the bit from
spinning.
