KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. In conjunction with DTH hammers, drill hammer bits are designed with a spline drive for rotating the bit in the ground. Drill bits are available in different sizes and different styles so they can drill a wide range of hole sizes. Our variety of Down the Hole (DTH) bits is manufactured using high quality materials to provide you with a fine balance between penetration capability and bit life.
Rock drill bits Shank type:M3,M4,M5,M6,M8,M1,M12
DTH hammer bits hole diameter: 3'', 4'', 5'', 6'', 8''(85mm-350mm).
You must consider several necessary factors when choosing a drill bit for your application. First, pay attention to the material of the drill bit. For example, different formation requires a different type of drill bit. Second, take into account the size of the hole you need to make. Match the bit diameter to the desired hole size to choose the proper size drill bit. Proper maintenance of your hammer drill is crucial to ensure its optimal performance and longevity. It is important to remember that investing in a high-quality step drill bit can save you money in the long run by lasting longer and providing more precise and efficient drilling.
All drill bits are manufactured in the most advanced facilities around the world, ensuring their availability and shorter delivery times regardless of where our customers are located. Our cutting-edge manufacturing processes and proprietary heat treatment ensure consistent quality, which translates into reliable and reliable drilling consumables. Precision engineering, world-class heat treatment technology, and high-quality tungsten carbide alloy steel make DTH drill bits stand out.
