Down the hole(DTH) tools manufacturer KINGDRILLING supply DTH Drill Bits with QL shank type are available in a wide range of sizes and with a number of custom design features for optimum performance in a rock formation, which are designed to match all conceivable applications for water well industries, mining and construction.
Rock drill bits Shank type:QL30,QL40,QL50,QL60,QL80,QL10,QL12
DTH hammer bits hole diameter: 3'', 4'', 5'', 6'', 8''(85mm-350mm).
Advantages of Down The Hole Drill Bits:
High Penetration Rates: One of the primary advantages of DTH drill bits is their ability to achieve high penetration rates. These bits are engineered to swiftly cut through various types of rock formations, making them ideal for projects where speed is essential.
Enhanced Efficiency: DTH drill bits are known for their efficiency in drilling operations. Their design enables them to maintain consistent performance even in challenging geological conditions, leading to faster completion of drilling tasks.
Versatility: DTH drill bits are versatile tools that can be used in a wide range of applications. Whether it's surface drilling, underground mining, or quarrying, these bits can adapt to different environments and rock types.
Longevity: Durability is a key advantage of DTH drill bits. These bits are built to withstand the rigors of heavy-duty drilling, offering a longer lifespan compared to conventional drill bits.
Precision: DTH drill bits are designed to provide precise drilling results, ensuring that the desired hole size and depth are achieved with accuracy. This precision is vital in applications where exact specifications are required.
Cost-Effectiveness: While the initial investment in DTH drill bits may be higher than standard drill bits, their long-term cost-effectiveness makes them a preferred choice for many drilling operations. The efficiency and durability of these bits often result in lower overall drilling costs.
