T45 76mm button drill bit hard rock tools for Hydraulic Rock Drill
Equipment
Button Drill bits
The button drill bit is mainly used for blasting hole excavation of
open pit rock drilling, underground mining, tunnelling and other
infrastructure projects. The connection mode is mainly T-threaded
connection and R-threaded connection. The top hammer hydraulic rock
drilling rods equipped with drilling rigs and open-air drilling
rigs are used to receive the energy transmitted by the rock drill
to achieve the effect of breaking the rock.
At present, the most used in engineering is the spherical bit and
the ballistic bit. Due to the special working environment of the
thread bit, we require that the thread drill bit should have high
wear resistance and impact resistance, and have sufficient
toughness to cope with the complicated and harsh working
environment. Our rock drilling bit is made of high-quality special
steel, the alloy head is made of high-strength and toughness wear-resistant alloy, and the whole
processing adopts special surface treatment, thus ensuring that our
bit is more durable and has higher fatigue resistance.
This type of bit is well known for its high wear resistance on
medium-hard to hard abrasive rock formations (between 200 Mpa to
260 Mpa compressive strength). Featuring spherical tungsten carbide
inserts that is known to have strong configuration against carbide
fracture
• Widely used in bench and long hole drilling

Button carbide shape
| Button shape | Application |
 | Hemispherical Buttons Universal button for all rock formations,best suited to hardest and
very abrasive rock formations |
 | Parabolic button Excellent penetration rate,but only suited to medium hard and not
so very abrasive rock formations |
 |
Conical button
For soft to medium rock hardness,more aggressive with faster
penetration rates.
|
 |
Ballistic button
Similar to Parabolic buttons,used for soft to medium hard and not
so abrasive rock formations,excellent in penetration rate |
