The 190mm DHD370 DTH Drill Bit is a high-performance drilling tool designed for demanding rock drilling applications. Built for durability, precision, and efficient energy transfer, it is widely used in mining, quarrying, construction, geothermal drilling, water well drilling, and foundation work. Its robust structure and reliable cutting ability make it suitable for medium to hard rock formations, where consistent penetration and long service life are essential.

This drill bit is engineered to work with DHD370 down-the-hole hammers, ensuring excellent compatibility and stable operation. The DTH system delivers impact energy directly to the bit face, which helps achieve faster drilling speeds and better hole straightness compared with many conventional drilling methods. With a diameter of 190mm, this bit is ideal for projects that require moderate-sized boreholes with high drilling efficiency and accuracy.

The bit body is typically manufactured from premium alloy steel, which provides superior strength and resistance to fatigue under repeated impact loads. To further improve durability, the working surface and button areas are often heat-treated and optimized for wear resistance. The design is focused on maintaining structural integrity even in harsh drilling environments, where high pressure, abrasion, and vibration are common.

One of the key features of the 190mm DHD370 DTH Drill Bit is its button arrangement. The carbide buttons are carefully positioned to provide balanced impact distribution and effective rock fragmentation. Depending on the rock conditions, the bit may be designed with different button shapes, such as spherical, ballistic, or semi-ballistic buttons. Spherical buttons are generally preferred for harder and more abrasive formations because they offer excellent wear resistance, while ballistic buttons can improve penetration rates in softer to medium-hard rock.

The air holes and flushing channels are also designed to remove cuttings efficiently from the borehole. Proper flushing prevents regrinding of cuttings, reduces heat buildup, and helps maintain drilling speed. This contributes to better tool life and lower operational costs. The face design may vary, including flat face, concave face, or convex face configurations, allowing users to choose the most suitable option for specific geological conditions.

In practical use, the 190mm DHD370 DTH Drill Bit offers a strong combination of penetration rate, hole quality, and service life. It is well suited for operators who need dependable performance in challenging environments. Its compatibility with pneumatic DTH systems makes it a popular choice for projects where compressed air is used to power the hammer and clear debris efficiently.

Overall, this drill bit provides a reliable and cost-effective solution for professional drilling operations. With its sturdy construction, advanced carbide design, and efficient rock-breaking performance, the 190mm DHD370 DTH Drill Bit helps improve productivity while reducing downtime and maintenance needs. It is an excellent choice for users seeking a durable and efficient tool for medium-diameter rock drilling tasks.
