Product Description

115mm HM4 Shank High Air Pressure DTH Hammer Bits for Oil Drilling

Product Description

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 Down The Hole (DTH) Drill Bits:

1. Unique Design: DTH drill bits are engineered with a distinctive design that sets them apart from traditional drilling tools. These bits feature a pneumatic hammer at the bottom of the drill string, which delivers powerful percussive energy directly to the drill bit.

2. High-Quality Materials: DTH drill bits are crafted from premium-grade materials such as tungsten carbide and high-strength steel, ensuring exceptional durability and resistance to wear and tear in harsh drilling environments.

3. Variety of Designs: DTH drill bits come in a wide range of designs, including button bits, ballistic bits, and specialized bits for specific applications. This variety allows operators to choose the most suitable bit for their drilling requirements.

4. Optimized Performance: DTH drill bits are designed for optimal performance, delivering high penetration rates, precise hole alignment, and consistent rock fragmentation, resulting in enhanced productivity and reduced operational costs.

5. Compatibility: DTH drill bits are compatible with various drilling equipment, including down-the-hole hammers, drill rigs, and compressor systems, making them versatile and adaptable to different drilling setups.

6. Easy Maintenance: These drill bits are engineered for easy maintenance and replacement of worn components, minimizing downtime and ensuring continuous operation on the drilling site.
