Thread Button 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.
We can also do according to customers' drawing or sample, no matter what kinds of rock- Soft rock, loose-medium rock, hard rock and any other special formations, just tell us what you need and leave others at our disposal.

| Bit Face Shape | Introduction |
| Drop Center Face | For high penetration rates in soft to medium hard and fissured rock formations, Low to medium air pressures. Maximum hole deviation control. |
| Concave Face | The all-round application bit face specifically for medium hard and homogeneous rock formations. Good hole deviation control and good fishing capacity. |
| Convex Face | For high penetration rates m soft to medium-hard with low to medium air pressures. It is the most resistance to steel wash. And many reduce the load and wear on the gauge buttons. But poor hole deviation control. |
| Double Gauge Face | This kind 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. |
| Flat Face Bit | This kind of face shape is suitable for hard to very hard and abrasive rock formations in applications with high air pressure. Good penetration rates are resistance to steel wash. |
Sollroc button bit is made by high quality tungsten carbides and steel,through heat treatment so that it can be used for hard rock drilling,and transmit intensive impact energy into the rock with the least possible loss of energy.Sollroc provides leading strength and penetration rates for more productivity,excellent straightness and hole clean quality,get max drilling performance to save up fuel cost rate.
We can also design and manufacture according to customers'samples or drawings of the diameter,buttons and flushing holes quantity,button shape and face shape.
