The DTH Drill Bit

A Down-The-Hole (DTH) hammer bit is a critical component in modern drilling operations, used primarily in mining, construction, and water well drilling. Unlike conventional drilling, the DTH hammer is located directly behind the bit in the drill string. Compressed air powers the hammer, which delivers rapid, high-energy impacts directly to the bit, crushing hard rock formations efficiently. The DTH bit itself is the frontline tool, featuring a robust steel body with strategically placed buttons that act as the cutting structure.

The PDC Spherical Button 1624

The PDC (Polycrystalline Diamond Compact) Spherical Button is a premium cutting element designed for these demanding applications. Its name derives from its specific geometry and size. The "Spherical" shape refers to its hemispherical, ball-like profile, which offers superior impact resistance and wear characteristics compared to cylindrical or conical buttons. The "1624" typically denotes a diameter of 16mm, a common and robust size for heavy-duty DTH bits.

This button is composed of a layer of synthetic polycrystalline diamond, the hardest known material, fused under high pressure and temperature to a tungsten carbide substrate. This combination creates a cutting element that is both incredibly hard on the surface (for abrasion resistance) and exceptionally tough in its core (to withstand heavy impact loads).

Advantages of PDC spherical button

The primary advantage of the PDC Spherical Button is its exceptional durability and performance in abrasive and hard rock formations. The spherical design allows for efficient rock crushing and provides a self-sharpening effect as it wears. This translates to faster penetration rates, longer bit life, and reduced downtime for bit changes, leading to significantly lower drilling costs per meter.

ZZbetter excels in manufacturing these high-performance components. We utilize state-of-the-art HPHT (High-Pressure High-Temperature) technology and advanced quality control systems to ensure every button has a flawless diamond table and a perfect interface with the substrate. Our proprietary manufacturing process guarantees superior impact and thermal stability, making our PDC Spherical Button the most reliable choice for maximizing the efficiency of your DTH drilling operations.
