PRODUCT OVERVIEW
DRILLING DEPTH GUIDELINES
Drilling capacities have been calculated from theoretical values
of the pull back system with 40% deduction for efficiency losses
to arrive at the above capacities. Therefore these values are
indicative only and depend on drilling conditions.
The KWL700 RC (Reverse Circulation) drill
is the largest of all Boart Longyear drills. Its
robust design features 40 000 kg (88,183 lb)
of pull back, a 38 m3/min at 34.5 bar (1,350
cfm at 500 psi) compressor, along with the
highest quality hydraulic pumps and motors
available in order to create a powerful and
reliable drill that can cope with the toughest
conditions. This rig delivers operational oil
flows at only 1500 rpm decreasing wear and
fuel consumption, while improving reliability.
The KWL700 also features the markets most
versatile RC Rod Handler.
