Overview of Carbide Tungsten R28 38mm Thread Button Bit Rock Tools for Drifting and Tunneling

Tungsten is a metallic element with the element symbol W and atomic number 74. It is located in the VIB group of the sixth period of the periodic table of elements. In nature, tungsten mainly exists in the form of hexavalent cations. Its ionic radius is small, it has strong polarization ability, and it is easy to form complex anions.

When preparing pure tungsten or tungsten alloy, the main methods include powder metallurgy, smelting (including electron beam melting, vacuum melting, plasma beam melting) and chemical vapor deposition.

Feature of Carbide Tungsten R28 38mm Thread Button Bit Rock Tools for Drifting and Tunneling

The thermal expansion coefficient of tungsten is very low, only 4.5×10^-6 m/mK, so it has good thermal stability. These properties make tungsten widely used in manufacturing high-temperature components and reliable heat detectors.

Parameters of Carbide Tungsten R28 38mm Thread Button Bit Rock Tools for Drifting and Tunneling

The Carbide Tungsten R28 38mm Thread Button Bit is a specialized rock drilling tool used in tunneling and drift mining operations. Here’s a breakdown of the key parameters:

1. Diameter (D): 38mm – The bit’s outer diameter, which determines the size of the hole it will create.

2. Size (R28): This refers to the flute size or the internal diameter of the bit. R28 means the flute has an outer diameter of 28mm and an inner diameter of about 26.5mm, allowing for efficient chip evacuation during drilling.

3. Type: Button Bit – A button bit has a conical shape with a flat face at the cutting edge, designed to provide better stability and reduce wear compared to other types like twist bits or core bits.

4. Material: Carbide Tungsten – The bit is made from a combination of tungsten carbide, a hard and wear-resistant material, and tungsten, which adds strength and toughness to the drill bit. This combination ensures long service life and high efficiency.

5. Application: Drifting and Tunneling – These bits are specifically designed for drilling in hard rock formations, such as those encountered during tunnel construction or mining operations. They are ideal for creating straight, accurate holes for bolting, ventilation shafts, or support structures.

6. Function: The drilling process involves applying pressure while rotating the bit to cut through the rock, creating a cylindrical hole with the specified thread (usually for securing bolts or pipes).

7. Thread: Although not explicitly mentioned, it is common for thread button bits to have a specific thread pitch and pattern suitable for anchoring or connecting components in the drilled hole.

Please note that additional specifications, such as the length, shank type, and overall length (OAL), may be required to fully describe the bit. These details would depend on the manufacturer and intended use.
