DTH Drill Bits Manufacturer
Introduction
What is DTH Drill Bit?
DTH (Down-The-Hole) Drill Bit is a specialized tool used in drilling applications, particularly for drilling into hard rock and tough materials.
DTH drill bits come in various sizes and designs, depending on the specific drilling requirements, and are often chosen for their durability and ability to withstand harsh drilling conditions.
How it works
- Position: The DTH drill bit is attached to the end of a drill string and connected to a DTH hammer.
- Pneumatic Action: Compressed air is sent down the drill string to the hammer, causing it to strike the bit in a rapid percussion motion.
- Rotational Drilling: While the hammer delivers impact energy, the drill string rotates the bit, allowing it to break through the rock or material.
- Efficiency: The DTH drill bit is designed to penetrate hard materials quickly and efficiently, making it ideal for applications like mining, quarrying, geothermal drilling, and construction.

Our top DTH Drill Bits
The SP series DTH drill bits are developed for diverse drilling needs, offering a range of sizes from 3 inches to 8 inches. These bits provide exceptional adaptability, making them suitable for water well drilling, quarrying, mining, and construction applications.
Made with high-strength alloy steel and precision heat treatment, SP bits deliver outstanding impact resistance and longevity. They are designed for use with SP high-pressure DTH hammers for the best performance.
The Speed Master Series DTH Drill Bits are engineered for high-speed drilling performance, making them ideal for projects that demand rapid progress. They are optimized for fast penetration in medium-hard to hard rock formations, significantly reducing drilling time without sacrificing accuracy or tool life.
Each bit is built with a high-strength alloy steel body and outfitted with premium tungsten carbide buttons, ensuring exceptional durability and aggressive rock-cutting capability.
The NDA Series DTH Drill Bits are designed for enhanced energy transfer efficiency, meaning they deliver more of the drilling hammer’s power directly to the rock.
This efficient energy use provides excellent performance in deep-hole drilling applications, where maintaining impact force at the bottom of the borehole is essential. Built with special alloy materials, NDA bits offer long-lasting durability and can withstand the demanding conditions of extended drilling campaigns.
The ND series DTH drill bits are engineered for efficiency in hard rock formations, making them ideal for mining, water well drilling, and geological exploration.
Manufactured from high-strength alloy steel with an optimized internal structure, ND bits maximize energy transfer in high-pressure drilling. They are best used with ND series DTH hammers to achieve superior drilling performance.
The QLA Series DTH Drill Bits are an advanced variation of the QL series, incorporating a sophisticated impact mechanism for superior drilling outcomes.
They offer improved stability and precision, particularly in deep and large-diameter drilling scenarios where keeping a straight, accurate borehole is paramount. These bits are specifically designed to be compatible with QLA high-pressure DTH hammers, ensuring efficient power transmission and maximizing impact energy at the cutting face.
The QL series DTH drill bits feature a tubeless design that enhances drilling speed and reliability. These bits work seamlessly with QL high-pressure DTH hammers, delivering high-impact energy for faster rock penetration.
They include various face and button configurations to accommodate soft, medium, and hard rock formations. QL bits are widely used in mining, open-pit blasting, and water well drilling.
The SD series DTH drill bits are a popular high-pressure design that is compatible with many major brands such as Atlas Copco. These bits are widely used for mining, quarrying, and construction drilling.
Constructed from premium alloy steel and reinforced with high-grade carbide buttons, SD bits maintain durability in demanding rock conditions. With multiple face and button designs available, SD bits can be optimized for different geological formations.
The Mission series DTH drill bits are designed for high-pressure drilling in medium to hard rock formations, widely used in mining, quarrying, water well drilling, and various infrastructure blasting projects.
They are fully compatible with Mission high-pressure DTH hammers, ensuring efficient and reliable energy transmission.
The Medium & Low Wind Pressure Series DTH Drill Bits are optimized for drilling operations using moderate to low air pressure. They are designed to perform efficiently in small to mid-scale projects, particularly in soft to medium-hard rock formations where ultra-high pressure equipment might not be available or necessary.
By operating effectively with lower air pressure, these bits help reduce compressor fuel consumption and overall drilling costs, offering an economically efficient solution.
