PIN-PIN (Male-Male) Adaptors For DTH Drill Rods

PIN-PIN (Male-Male)  Adaptors For DTH Drill Rods

In DTH drilling, the rock drilling bit is a continuation of the shank, which the rock drill piston strikes directly. Since the piston is in direct contact with the drill bit, little energy is lost. This gives DTH drilling a nearly constant penetration rate regardless of hole length.

We offer three types of adapters to meet your needs:

• 1.BOX-BOX (Female-Female) Adapters
• 2.PIN-BOX (Male-Female) Adapters
• 3.PIN-PIN (Male-Male) Adapters.

Our products can be customized in terms of length, outside diameter (O.D.), inside diameter (I.D.), and thread combinations to fit your specific requirements. Contact us today to learn more about our high-quality adapters for DTH drilling.
