Mincon HDD70PR Pull Reamer

The Mincon HDD70PR pull-reamer hammer uses our proven technology to define the benchmark for HDD tools. Thanks to its patented, reverse-airflow hammer cycle, it can reliably be used to ream pilot bores between 89mm (3½”) and 108mm (5¼”), to a full hole size of 229mm (9"). Mincon's design means that minimal feed and rotational force are required from the drilling machine, thanks to the high-pressure, high-volume air that powers the hammer.

  • Bit Options: 178mm, 203mm, 229mm (7”, 8”, 9”)
  • Thread type: 2⅜” – 3.5” API Reg Pin
  • Minimum Air Package under 250’ (76m):  25.5 m³/ min @ 24.1 bar (900 cfm @ 350 psi)
  • Minimum Air Package Over 250’ (76m): 35.42 m³ / min @24.1 Bar AC* (1,250 cfm @ 350 psi AC*)
