11 Degree Taper Tungsten Carbide Bits For Small Hole Rock Drill Button Bits
Describtion
Miroc 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.
Why you choose Miroc button bit?
1. Tapered button bits connect with tapered drill rod perfectly for drilling holes
2. Stable and mature welding technology ensure high quality of bits
3. Accurate dimension of taper degree perfectly matches the rods
4. work reliable and very cost-effective
5. High grade tungsten carbide inserts
6. Bit bodies manufactured from high grade steel and processed using state-of-the-art CNC machinery and heat treatment
