Manufactured from high-strength alloy steel, the bit body provides excellent structural strength and resistance to impact and wear. High-quality tungsten carbide buttons are designed to withstand repeated impact loads and abrasive rock conditions, helping extend service life and reduce drilling tool replacement frequency.
The optimized button layout promotes effective rock penetration and uniform load distribution during drilling. Carefully designed cutting surfaces help improve rock fragmentation, maintain drilling stability, and support consistent performance in medium-hard to hard rock formations. The appropriate button configuration can be selected according to rock hardness, abrasiveness, and site conditions.
The flushing passages help direct compressed air toward the drilling face to remove rock cuttings and maintain an efficient drilling process. Effective debris removal helps reduce recutting, supports stable hole cleaning, and contributes to reliable drilling performance when operating conditions and air supply are properly matched.
With a nominal diameter of 110mm, this DTH hammer bit is suitable for various rock drilling operations, including mining blast holes, quarry drilling, foundation construction, water well drilling, and other industrial drilling applications. Its robust construction is designed to support demanding field operations and help improve overall drilling productivity.
Designed for use with a compatible DHD3.5 DTH hammer, this bit is available for professional drilling applications requiring dependable performance and durability. Different carbide button shapes, face designs, and customized specifications may be available according to project requirements. Please confirm the shank specification, bit diameter, button configuration, and drilling conditions before ordering to ensure proper compatibility.
Please confirm shank specification, bit diameter, button configuration, and drilling conditions before ordering to ensure proper compatibility with your DHD3.5 hammer.
