Products Description
LEANOMS
Tungsten carbide button bits, often referred to simply as carbide button bits, are specialized cutting tools used primarily in drilling operations. These bits are known for their durability and are used in various industries, including mining, construction, and oil and gas exploration.

Cold pressing and hot setting are two different manufacturing processes used to produce thread drill bits. These processes are employed to create the threaded connection between the drill bit and the drill rod or pipe. Each method has its own advantages and applications:
Cold Pressing:
Process: Cold pressing involves pressing the thread onto the drill bit's body at room temperature. This process typically uses high-pressure machinery to form the threads.
Advantages:
- Cost-Effective: Cold pressing is generally more cost-effective than hot setting.
- No Heat Stress: Since no heat is applied during the process, there is no heat stress on the drill bit's material, which can maintain the bit's original properties.

- Suitable for Certain Materials: Cold pressing is suitable for softer materials that might not withstand the heat of hot setting without deforming.
Limitations:
- Limited Hardness: The threads formed through cold pressing may not achieve the same level of hardness as those created through hot setting, which can affect their durability in abrasive drilling conditions.
- Limited Precision: Achieving precise thread dimensions and tolerances can be more challenging with cold pressing compared to hot setting.
- Applications: Cold pressing is often used for smaller and less demanding drill bits, such as those used in construction and foundation drilling.
Hot Setting:
Process: Hot setting, also known as heat treatment, involves heating the drill bit to a high temperature to make it more malleable. Threads are then cut or formed into the hot metal, which is subsequently cooled and hardened.
Advantages:
- High Hardness: The threads formed through hot setting can achieve higher hardness levels, making them more durable in abrasive rock formations.
- Precise Thread Profiles: Hot setting allows for precise control over thread dimensions and tolerances, ensuring a tight and reliable connection.
- Greater Thread Strength: Hot-set threads tend to have greater tensile strength compared to cold-pressed threads.
Limitations:
- Higher Cost: Hot setting is generally a more expensive process due to the energy required for heating and the precision involved.
- Heat Stress: The application of high heat can introduce stress to the metal, which may require additional tempering or heat treatment to maintain material properties.
- Applications: Hot setting is often used for larger and more heavy-duty drill bits, particularly those designed for demanding applications in mining and oil drilling, where thread strength and durability are crucial.

Thread drill bits usually use different thread specifications to match different models of drill pipes and drilling rigs. These specifications are used to ensure compatibility between the drill bit and other drilling equipment. Here are some common thread specifications:
T38 Thread: T38 is a common thread specification commonly used for underground and surface hard rock drilling. T38 has larger threads and is suitable for most hard rock drill bits and is suitable for highly wear-resistant rocks.
R32 Thread: R32 is another common thread specification commonly used for underground and surface hard rock drilling. It is smaller than the T38 and therefore suitable for smaller drill bits and moderately hard rocks.
T45 Thread: The T45 specification is used for large-scale hard rock drilling work, usually in underground mines and quarries. This specification is suitable for large drill bit sizes capable of handling challenging rock types.
T51 Thread: The T51 specification is a larger thread specification typically used for large underground and surface hard rock drilling jobs. This specification is suitable for large wear-resistant rocks.
ST58 and ST68 Thread: ST58 and ST68 are some thread specifications used for large rock drilling work, usually used in mines and large foundation projects.
