Product Description

The 152mm DHD340A-152 DTH drill bit is engineered for water well drilling and demanding rock drilling operations. Reinforced with embedded premium PDC cutters, it features a hybrid carbide button structure with dome and semi-ballistic inserts plus a dual-size face button configuration to provide stable penetration, enhanced gauge protection, and long service life.

Embedded Premium PDC Cutters for Maximum Wear Resistance

The DHD340A-152 DTH drill bit combines premium tungsten carbide buttons with strategically embedded PDC cutters to create a durable hybrid drilling structure. The embedded PDC cutters strengthen the gauge area, reducing wear while helping maintain accurate hole diameter during extended drilling operations.

Unlike conventional button bits, this model features a dual-size face button arrangement consisting of 4 × 17 mm and 4 × 14 mm carbide buttons. This optimized configuration distributes impact energy more evenly across the drilling face, improving rock fragmentation while maintaining stable penetration.

The combination of dome and semi-ballistic carbide buttons delivers an excellent balance between impact resistance and drilling efficiency, making the DHD340A-152 an ideal choice for water well drilling in medium-hard to hard and abrasive rock formations.
