The Features about 152mm drill bit
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption due to the special inner structure of HD series DTH hammer designed according to newest rock drilling theory.
2. Smooth performance and long service life of DTH hammer due to high quality alloy steel materials and advanced processing technology adapted.
3. Low problem rate and easy to maintenance due to simple, reliable and easy assemble and disassemble inner structure of hammer.
4. Easy to depart bit from hammer due to multi-head thread connecting chuck and cylinder of hammer.
5. The dth hammer button bits can interchangeable with DTH bit and drill pipe.
Drill Bit Characteristics
01/
Flat Face: This flat face is suitable for drilling very hard rock formations and corrosive wall formations at high air pressures, when the bits are drilling. The faster the drilling speed, the less wear of the drill body.
02/
Concave Face: This Concave face is suitable for all rock formations, especially in medium-hard and homogeneous rock formations, the effect is good. The blast hole deviation is small, and the slag discharge effect is good.
03/
Double Gauge Face: This double-sided button face is suitable for drilling very hard rock formations at high air pressures. When the bits is drilling, drilling speed is fast, the bit body wear will also be less.
04/
Drop Center: Dth drill bits for rock drilling when using low-medium pressure to drill soft-medium hard and fractured rack formations, in order to obtain fast rock drilling speed and less blast hole slope, this face shape is usually used.
05/
Convex Face: This Convex face is suitable for low-to medium-pressure drilling of soft-medium hard rock formations, and the drill block is not easy to corrode. The characteristics of this design are the low load of the side button, the wear is not badly and the drilling speed is fast.
Application
dth hammer button bits are mainly used in geological exploration, coal mine, water conservancy and hydropower, highway, railway, bridge, construction and construction, etc.
