7°/11°/12° High Speed Rock Drilling Tungsten Carbide Tapered Drill Bits
7°/11°/12° Tapered Cross Bit , Mining/Qaurring Cross Bit
Product Specification
MirocTapered 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.
Our Advantages:
1.Tapered button bits connect with tapered drill rod perfectly for drilling holes
2.Stale 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
Application:
• Suitable for small hole range
• Widely used in Dimensional Stone Quarrying Industry
• Widely used in Underground Mining Industry
