The DHD3.5 drill bit is a common DTH hammer drill bit model, widely used in mining, geological exploration, water well drilling, and construction projects. It connects with the drill pipe through API standard threads to ensure stability and reliability.

Manufactured with high-quality materials and advanced technology, the DHD3.5 drill bit offers extended service life and reduced replacement frequency.

This high air pressure DTH drill bit features our newest design and represents one of the most advanced DTH drill bits available worldwide.

Ideal for use in mining, energy, metallurgy, geology, coal, water conservancy, chemical industry, and road construction applications.
