Key Features and Benefits

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 Transmits to pipe joints and gearbox assembly reducing maintenance requirements to drill. 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, Subsite, or WIRELINE) can be used with no additional cost to the contractor.
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.

Lubrication

DTH hammers must receive a constant supply of proper rock drill oil to protect the internal components and to provide a good air seal between the hammer\'s running surfaces for efficient drilling. Mincon recommends the use of Mincon Envirosafe® Rock Drill Oil (RDO) to maintain optimal performance and extend the life of the internal components. The correct consumption of oil is dependent upon the air volume and conditions. Please refer to the lubrication graph below for recommendations. When drilling in wet conditions the normal amount should be doubled. There should be visual evidence of oil around the drill bit shank and within the tube joints when changing tubes.

If using petroleum based rock drill oils, the recommended grade of oil is dependent on the ambient temperature and the operating pressure. As a rule of thumb, ISO320 grade rock drill oil should be used whenever possible as the hammer is a high frequency tool, however, where the pump cannot pump the oil in colder conditions, a lower grade of oil can be used as per the graph below.
