Our 3-inch high-pressure DTH bits combine a compact, lightweight design with superior impact resistance, making them the perfect solution for confined and challenging environments. Engineered to work with high-pressure air systems, these bits deliver exceptional penetration rates and maximum drilling efficiency.
Built with premium-grade tungsten carbide buttons, our bits ensure long service life and stable performance in hard rock formations. Whether for mining, water well drilling, or civil engineering, choose our 3-inch bits to achieve faster cycles and lower your total operational costs.
Advantages
The 3-inch high air pressure DTH bits feature a durable alloy steel body designed to withstand repeated impact loads during high-pressure drilling operations. The robust construction helps maintain structural integrity under demanding rock drilling conditions, supporting reliable performance in mining and quarrying applications.
Equipped with high-quality tungsten carbide buttons, these high air pressure DTH bits provide effective rock penetration and wear resistance. The button arrangement is designed to distribute impact forces across the drilling face, helping maintain consistent rock-breaking performance in hard and abrasive formations.
The flushing hole design supports compressed-air circulation during drilling, helping remove rock cuttings from the borehole. Effective cuttings removal reduces the accumulation of drilling debris around the bit face and helps maintain stable drilling conditions.
Available bit face configurations include flat face, convex face and drop center designs. Different face profiles provide options for varying geological conditions and drilling requirements. Buyers can select the appropriate configuration according to rock hardness, formation characteristics and drilling objectives.
