The T-thread specifications such as T38, T45, T51, etc., are commonly used in the industry. The basic dimensions and button profile of T-threads mainly follow the corporate standards of each company, but they are generally similar across the industry. As a result, drill bits with T-threads are highly interchangeable. In particular, Tianyue's rock drilling bit is well suited for non-abrasive drilling conditions.
Features:
The threaded drill bit, equipped with the hydraulic drilling jumbo, is used for crushing rock. It is widely utilized in tunnel construction, large-scale open and underground mines, as well as for large section tunnel advancement in metal mining.Our threaded button bit is manufactured using the highest quality alloy steel bar and tungsten carbide. It undergoes a heat treatment process, ensuring its durability and performance. The threaded button bit comes in various sizes, including R25, R28, R32, R35, R38, T45, T51, ST58, GT60, ST68, and more. Additionally, the head diameter ranges from 35mm to 127mm.Our special technology allows us to develop the sharpest ball tooth, which is ideal for drilling through hard and mid-hard rock formations. These bits are equipped with sharp buttons that provide excellent wear resistance and enable high driving speed. On the other hand, our bits with round buttons are specifically designed for drilling in hard rock formations. They offer the advantage of high abrasion and impact resistance, making them widely used in various challenging drilling operations. With our advanced technology and exceptional bit designs, we are confident in providing our customers with reliable and efficient drilling tools for different rock conditions.

| Face Design | Application |
 | Flat face button drill bits are suitable for all rock conditions, especially for the rock with higher hardness and higher abrasiveness. Such as granite and basalt |
 | Convex Face button bits are designed for fast penetration rates in softer rock. |
 | Drop center button drill bits are mainly suitable for the rock with low hardness, low abrasiveness, and good integrity. The bits can drill straighter holes. |
|
| Normal Skirt For drilling in very hard and abrasive rock formations. |
|
| Retract Skirt For drilling in loose,broken or fissured rock where it is difficult to retract the drill string due to the hole collapse. |
| Button Shape | |
 | R：Round Utility carbide shape. Stong configuration against carbide fracture. |
 | B:Ballistic Higher penetrating carbide shape than Semi ballistic shape. Recommended for soft rock. |
| BB：Semi Ballistic Combined wear resistance and high penetration rate. Recommended for medium-hard rock with moderate abrasitivity. |
 | SA:Spike Highest penetrating carbide shape. Weak configuration against carbide fracture. Recommended for soft to medium-hard work. |
