CTIA GROUP’s tungsten carbide button bits, serve as key components of drilling tools in mining operations. By being embedded into the working surface of drill bits, they bear the task of impacting and crushing rock. Their spherical or near-spherical design helps distribute stress during drilling and maintain penetration performance under varying rock conditions.
CTIA GROUP and its parent company, CHINATUNGSTEN ONLINE, have been dedicated to the tungsten-molybdenum products industry for nearly 30 years. They specialize in providing flexible, customized global services for tungsten-molybdenum products, designing, manufacturing, and precisely processing various standard specifications, grades, and dimensional precision according to customer requirements, suitable for a wide range of applications.

Wide application of tungsten carbide button bits can be found in mining operations, which are mainly mounted on roller cone bits, down-the-hole (DTH) bits and hydraulic rock drill bits for drilling blast holes, exploration holes and production holes. These drilling tools operate in both open-pit and underground mining, adapting to extraction requirements of different scales and geological conditions.
In open-pit mining, CTIA GROUP’s tungsten carbide button bits are commonly used in medium to large roller cone bits and DTH bits. They cover a wide range of drilling diameters, suitable for blasting hole drilling in coal mines, metal mines, and non-metallic mines. Underground mines tend to use button bit drill heads on hydraulic rock drills or small to medium-sized DTH drilling tools to accommodate limited working space and complex geological structures.

On the drill bit face, tungsten carbide button bits are arranged in specific patterns. Through rotation combined with impact or pure impact action, they induce fatigue cracks in the rock and achieve crushing. This configuration is effective in medium-hard to hard rock formations, supporting continuous drilling operations. On-site in quarries, metal mines, and non-metallic mines, button bits are also used for rock crushing during tunnel excavation, roadway development, and related infrastructure construction.
Additionally, in some coal and non-ferrous metal mining operations, tungsten carbide button bits are paired with high-pressure DTH hammers to support deep-hole drilling. The shape of the button bits (e.g., spherical, semi-ballistic) and their layout are adjusted according to rock hardness, abrasiveness, and drilling method to match specific working conditions.
The performance of tungsten carbide button bits in mining depends on rock type, drilling parameters (such as impact energy, rotation speed, axial pressure), and flushing media. In highly abrasive formations such as granite and quartzite, their hardness helps control wear rate; in medium-hard formations, properly arranged button bits support penetration efficiency. On-site, different sizes of button bits, when matched correctly, can achieve long service life, reducing equipment downtime.
