While providing the most complete range of pilot hammers, Mincon also provides their world class design and technology including:

  • Patented reverse air flow hammer cycle allows for pull reaming of a pilot bore of 3-1/2” (89mm) out to 7-8” (178-203mm) and 4-1/4” (108mm) out to 9” (229mm) with the HDD70PR and pull reaming of a pilot bore of 5 1/4” (133mm) out to 10-12” (254-305mm) and 6 1/4” (159mm) out to 14” (356mm) on the HDD80PR.
  • A range of bits are offerred with different grades of standard carbide and diamond enhanced carbide to maximize bit life in every drilling condition.
  • High pressure/high volume compressed air powers reaming operations and requires minimal torque and feed pressure loads on drill machine increasing overall life of drill.
  • Attachments can be used to pull utilities as the hole is reamed.
  • Mincon Support Station delivers compressed air mixed with a water/polymer (5-9 gal/min) and rock drill oil (2-4 pints/hr) to operate the drilling cycle resulting in minimal environmentally friendly clean up. Can be used on environmentally sensitive locations using Mincon Envirosafe RDO biodegradable rock drill oil.
