Product Description
The DHD350-140 DTH hammer bit features a flat face design with a hybrid dome and semi-ballistic carbide button configuration and DHD350 shank. Engineered for water well drilling and quarrying, it delivers high penetration rates, good steel wash resistance, and reliable performance in medium hard to hard rock formations.
Embedded PDC Cutters for Efficient Bench Drilling
The DHD350-140 DTH drill bit is equipped with strategically embedded premium PDC cutters to strengthen the gauge area and improve drilling efficiency in high-production quarrying operations. By integrating wear-resistant PDC cutters with durable dome and semi-ballistic carbide buttons, the bit delivers reliable penetration while maintaining consistent hole diameter throughout extended drilling cycles.
The flat face design provides excellent energy transfer to the rock surface, making this model particularly effective in hard and abrasive formations. Whether used for bench drilling, blast hole preparation, or quarry production, the reinforced cutting structure helps reduce gauge wear, extend bit service life, and improve overall drilling productivity.
Features
