Audited Supplier Sollroc's thread button drill bits are made with high quality alloy steel bar and tungsten carbides, through heat treatment so that it can withstand the toughest rock drilling demands, and transmit intensive impact energy into the rock with the least possible loss of energy.
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.
| Product Name: | Thread button bits |
| Description: | For different rock hardness mining,tunneling,quarrying projects. |
| Material: | Alloy steel bar and tungsten carbide bit |
| MOQ: | trial order 1-5pcs |
| Body Type | Normal type and retract type |

| 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. |
1. High-strength structure alloy steel and carbide.
