System Features

Dual steering point design incorporating slanted drill bit and 2° bent sub provides more responsive steering capabilities while transitioning in and out of rock formations.
High frequency hammer cycle transmits less vibration that can be detrimental to sensitive electronics. Rock formations fracture into smaller pieces which are easier to flush out of the bore hole. Less stress transmited to drill pipe and tool joints. Provides the most effective steering in any pneumatically powered HDD system.
High pressure/high volume compressed air powers drilling operations and requires minimal torque and feed pressure loads on drill machine increasing overall life of drill.
Shorter body design compared to competitive models allows for easier steering in the bore hole and less rotational stresses on hammer body.
Existing locating electronics (DCI, Sub SITE, or WIRELINE) can be used.
Support Station delivers compressed air mixed with a water/polymer (3-5 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 biodegradable rock drill oils.

The Mincon HDD Story

In 2002 Mincon, in collaboration with leading industry professionals, started design and manufacturing of a range of pneumatically powered horizontal directional drilling systems to service the trenchless utility industry. Since then the tools have become the benchmark for steerable drilling systems in medium to hard rock where conventional directional drilling systems struggle.

The Mincon Hardrock range offers the most complete line of steerable hammer systems on the market, covering pilot holes from 3 ½” (89mm) to 6 ¼” (159mm). With the Mincon Hardrock Support Station and hosing any conventional HDD machine can be converted for rock drilling. The sonde carriage can be easily adapted to your existing locating equipment.

Utilizing “high Frequency Cycle” technology Mincon hammer systems provide many benefits to the contractor. Small chip production and faster material removal from the bit face keeps the bore hole cleaner and reduces the possibility of getting stuck. With less vibration to the drill string you ensure less wear and tear to the rig and locating sonde. Steering capabilities are greatly improved and in head to head tests against other competitor manufacturers the Mincon Hardrock systems out steered in dirt, cobble and solid rock.

Mincon offers the revolutionary Pull Reamer system. Once the pilot hole has been drilled, the pilot hammer and sonde is removed and the pull reamer is attached to the drill string. The pull reamer is then drawn back towards the drill machine and the pilot hole is hammer reamed out to a current maximum of 14” (356mm). This innovative reaming method is the fastest way to ream a rock bore and is vastly superior to conventional methods in all rock conditions.

The philosophy at Mincon is to provide “World Class” products, training, service and support. We like to think that we are with you from beginning to end. The Mincon Hardrock systems are the only systems available that can offer the contractor the peace of mind that comes with superior performance, reliability, innovation and complete support. Be wary of imitators that promise the world but just can’t deliver.
