KINGDRILLING hammer bits are used with Down-the-hole hammers for drilling holes through a wide range of rocks types. 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.
Features of High Air Pressure Drill Bits:
Tungsten Carbide Inserts: Many high air pressure drill bits feature tungsten carbide inserts on the cutting edges. Tungsten carbide is a durable material that can withstand high temperatures and abrasion, ensuring longevity and performance.
Optimized Flute Design: The flute design of these drill bits is optimized to facilitate efficient chip removal and cooling during the drilling process. This feature helps prevent overheating and prolongs the life of the drill bit.
High-Quality Steel Body: The body of high air pressure drill bits is typically made of high-quality steel to provide strength and durability. This robust construction allows the drill bit to endure the rigors of demanding drilling applications.
Multiple Cutter Configurations: Depending on the specific drilling requirements, high air pressure drill bits may come in various cutter configurations, such as PDC (polycrystalline diamond compact) cutters or roller cone cutters, to optimize performance for different materials.
Pressure Compensation System: Some advanced high air pressure drill bits are equipped with pressure compensation systems that help maintain consistent performance and stability under varying drilling conditions.
