Thread Button 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.

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.
Bit Face Shape Selection
1.Drop Center Bit:For high penetration rates in soft to medium hard and fissured rock formatios 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 fIushing capacity
3.Convex Face:For hiigh penetration ratas m soft to medium-hard wlth low to medium air pressures It is the most rasistance to steel wash. and many reduce the load and wear on the gauge buttons. but poor hole deviation control.
4.Double Gauge Face:This kind face shape is suitable for fast penetration rates in medium to hard rock formations. Designed for high aii 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 appllications with high air pressure. Good penetration rates an resistance to steel wash.
