Button Cemented Carbide for Rock Drilling Tools


Button cemented carbide is widely used as an excavating tool in quarrying, mining, and tunnel excavation. In addition, it is also used as a drill bit accessory for hydraulic rock drills or deep hole drill tool accessories. Among them, it is button carbide drill bit which most widely used for rock drilling matched for hydraulic rock drills.

Tooth profile of used in the button cemented carbide drill bit are divided into four shapes: hemispherical teeth, conical teeth, parabolic teeth, and wedge teeth.

1. Under the condition of sufficient impact power of hydraulic rock drill, the hemispherical teeth have high energy utilization rate, good rock breaking effect, and the alloy teeth are strong and wear-resistant, which is more suitable for oil well drilling. Hemispherical teeth are used to inlay rock drilling percussion bits, down-the-hole drill bits and oil drilling bits, suitable for very hard rock formations.

2. The alloy ball tooth of conical tooth shape is easy to drill into the rock, the drilling speed is higher. Conical teeth work more effectively when the impact energy is insufficient (the wind pressure of the wind power rock drill is insufficient, the performance of the hydraulic rock drill changes, etc.), but the abrasion resistance is poor. The teeth used to inlay rock drilling percussion bits, down-the-hole drill bits and oil drilling bits, suitable for hard rock formations.

3. Parabolic button is a crown shape between conical and hemispherical teeth. It is mainly used to inlay down-the-hole drill bits and roller cone bits, and is suitable for medium-hard rock formations.

4. Wedge-shaped button is mainly used to inlay special-shaped DTH drill bits and roller cone bits, and is suitable for soft rock formations with high speed and low tooth breakage.
