PK6500 Rotary Head

The PK6500 rotary head is a heavy-duty rotation unit designed for demanding DTH drilling and casing work up to 813 mm. Manufactured in Finland, it delivers high torque, stable rotation, and reliable drill string drive in hard rock, large-diameter casing operations, and extreme ground conditions.

  • STABLE ROTATION UNDER LOAD
  • BALANCED TORQUE AND SPEED
  • RELIABLE PERFORMANCE IN ROCK

Benefits of the Tri-Mach PK6500 Rotary Head

  • Stable rotation under load: Maintains steady drill string rotation during DTH hammer drilling, reducing the risk of binding and improving control in the hole.
  • Balanced torque and speed: Torque and rpm are matched for medium-diameter casing work, enabling efficient drilling without excessive wear or loss of control.
  • Designed for DTH drilling: Built specifically for DTH hammer use, ensuring proper load handling, rotation stability, and compatibility with drilling systems.
  • Integrated air flow system: Internal air swivel allows continuous air supply through the drill string, supporting hammer operation and effective flushing.
  • Simple and robust structure: Mechanical simplicity reduces failure points and ensures reliable operation in demanding site conditions.
  • Proven Finnish engineering: Designed and manufactured in Finland, based on decades of rotary head development since the 1990s.
