Product Introduction
Sollroc's thread button drill bits are made by high quality alloy steel bar and tungsten carbide inserts. Through heat treatment, our drilling tools are tough enough to meet rock drilling demands and have the least loss of energy while drilling the rocks.
The thread button bits are widely used in metallurgy mine, geological exploration, water conservancy construction, electricity, traffic, tunnel, quarry, national defence stone project etc.

| 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. |
Product advantage
1. Deliver maximum energy to drilling bit, fast drilling speed and low air consumption
2. Smooth performance and long service life
3. Low problem rate and easy to maintenance
4. Easy to depart bit from hammer
5. Interchangeable with DTH bit and drill pipe

About us
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.
