thread drilling bits
Product details
1.These threaded button bits can meet different drilling requirements in all rock formations.
We can also offer special designs according to the customer's requirements for specific work situation.
2.The button bits can transmit intensive impact energy into the rock with the least loss of energy.
3.We select high-strength structure alloy steel and carbide with best quality to ensure the drill body and alloy body can achieve uniform wear, thus the service life of bits will be increased.
features:
1. made with best quality alloy steel bar and tungsten carbide buttons, through special heat treatment
2. suitable for all kinds of rock—Soft rock, loose-medium rock, hard rock and any other special formations.
3. equipped with rock drilling machines such as Atlas Copco, Boart long year, Sandvick, Ingersoll-Rand, Furukawa.
4. exporting to Middle East, South Africa, Europe, South Asia, Southeast Asia, etc.
Bit face shape selection:
1. Drop Center Bit
For high penetration rates in soft to medium hard and fissured rock formations. Low to medium air pressures. Maximum hole deviation control.
2. Concave Face
The all-round application bit face specifically for medium hard and homogenerous rock formations. Good hole deviation control and good flushing capacity.
3. Convex Face
For high penetration rates in soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash, and may reduce the load and wear on the gauge buttons, but poor hole deviation control.
4. Double Gauge Face
This kind of face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high air pressures and good resistance to steel wash step gauge bit.
5. Flat Face Bit
This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressures. Good penetration rates an resistance to steel wash.
