12°Tapered Connection Button Bit
Usage： Taperbutton bit is use for Tunneling, Mining, Quarrying, Well drilling, Mining drilling, Ore drilling
Taper Angle (Degree): 7degree, 11degree, 12degree
Size: 28mm, 30mm, 32mm, 34mm, 36mm, 38mm, 40mm, 42mm, 46mm, 48mm, 50mm, 55mm, 60mm, 70mm, 80mm
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.
Why Choose Us:
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
USES:
Jayalakshmi's high quality top hammer rock drilling tools, which are widely use in mines, quarries, earthworks and other
engineering drilling blasting hole, guardrail hole, mountain reinforcement, anchorage and other engineering holes, geothermal
exploration hole, well bore and other fields.
