DE700 series

heavy duty core drills

Powerful drill rigs
with efficient footprints
E X P E R I E N C E D A N D P R OV E N

Sandvik has brought together some of the industry’s most
outstanding expertise, products and experience to provide
a unique offering in the area of exploration drilling. The
Sandvik heavy duty DE700 series consists of two dedicated
and powerful diamond core drills for surface exploration
applications - the DE710 and DE740. They are designed
for deep hole drilling and can be found in a wide range of
drilling operations such as mineral exploration, directional
drilling and geotechnical drilling all over the world - from
easy-access open pit mines to the remotest of areas. Thanks
to close cooperation with customers, these heavy duty drill
rigs for deep hole drilling can meet requirements in an impressive range of applications.
C O N F I G U R E D T O Y O U R A P P L I C AT I O N

The smaller in the series, the DE710, still has a remarkable
depth capacity up to 1126 m (3693 ft) with N size rods.
The DE740 is bigger and stronger with a depth capacity up
to 1837 m (6025 ft) with N size rods. The DE700 series is
available in a range of configurations which make the drills
uniquely suitable for operational and environmental
demands globally. The drills can be truck-mounted for
greater maneuverability and ease of relocating the drills between sites or can be fitted on crawler tracks, powered from
the rig hydraulic system, making the drills self-propelled
units for areas with difficult site access. The space efficient
design has proven a great benefit on sites where a small foot
print is required.

DE710
The DE710 is a space efficient and powerful diamond core
drill with a heavy duty base frame. The versatile DE710 is
available in a range of different configurations to suit global
operational and environmental demands.
■■ P-size rotation head chuck drive
■■ 6 m (20 ft) rod pull capacity
■■ Pull down 53,2 kN (12 000 lbf )

DE740
The powerful DE740 has a design that allows pulling and
running of rods and casings in 9 m (30 ft) lengths. With its
efficient design and possibility to telescope the mast making it 1,8 m (6 ft) shorter, it can be configured to suit your
transportation needs.

Select the right model and configuration to meet your applications needs in core drilling. With strategically located
Sandvik regional offices around the world to support you
with spare parts and service, drilling can be carried out with
minimal downtime.

Robust and reliable
for high productivity
The design of the head traverse system includes a hydraulic cylinder that is directly coupled to the rotation head carriage. This
design significantly reduces the amount of moving components
and reduces the overall maintenance costs for the drill.

The operator has excellent accessibility for both
minor and major maintenance work thanks to the
drill’s open design. The robust drill mast is designed
so the parts at the top can be easily accessed and
maintained.
ROBUST AND RELIABLE MAST
■■ Capacity to angle drill between vertical and 45°
- Flexible drilling
■■ Mast dump stroke is 1067 mm (3'5'')
- Ensures the mast is always able to make contact with the ground
- Flexible drilling even at acute angles or uneven drill pad
- Allows the mast to be as low as possible to ground
level, for ease of operation by driller and helpers
■■ The design allows for pulling of core tubes and casings
up to 6 m (20 ft) for DE710 and up to 9 m (30 ft) for DE740
- Improves productivity
- Longer continuous core runs without drilling stoppage
■■ Telescoping upper mast for DE740
- Lowers to near horizontal position and telescopes 1,8 m
(6 ft) shorter for transportation

Rotation unit for the job
■■ A variable displacement hydraulic motor drives the
rotation head gearbox
- Pilot-adjustable torque-speed control
- Controlled by operator from control panel
■■ High/low manual gear change
■■ Stepless speed control
- Speed control can be very precise
- Improves life time on bit
- Easier to spin
■■ Air to oil lubrication, oil cooler fitted
■■ Efficient hydraulics for maximum output torque
- Higher productivity

The powerful rotation unit features more torque for
higher productivity and has a simple design for easy
maintenance.
The long feed stroke combined with the ability to side
rack the rotation head provide the driller with more flexibility and supports higher productivity.

To help the operators and to provide a safer working
environment, the DE710 and DE740 are equipped
with rod spin guards.

Operator’s platform allows the driller to have an
ergonomic work place.
Hydraulic leveling jacks make set-up fast and easy
and provide an ideal drilling position.

Highly efficient hydraulics
■■ Highest quality axial and radial piston pumps and motors
used in three independent open loop circuits
■■ Full flow 10 micron Beta rated return oil filtration
■■ Larger than typical hoses and control valve sizes used
- Highest possible circuit efficiency
- Greater flexibility
- Precise control of critical drilling functions
- Proven reliability over thousands of hours

diesel engines for top performance
■■ Peak power rating of 134 kW (180 hp) at 2200 rpm for
DE710 and 194 kW (260 hp) at 2200 rpm for DE740
- Complies with Tier 3 emissions standards
- Provides low emission output combined with fuel
efficiency and performance
- Low weight and high performance engine
■■ The cooling system has been design for operations in
ambient temperatures up to 50°C (122°F)
■■ Hydraulically powered waterpump with a capacity of
140 l/min (37 GPM) at pressures up to 7000 kPa (1000 PSI)
- Flow rate is controlled and is infinitely variable
- All controls are located in the operator’s control panel

These calculations are based on feedback from field operatives and can be reasonably expected with vertical, water filled holes, by a well-trained drilling crew
using high quality drilling tools. Sandvik cannot guarantee that these results will be achieved in all drilling conditions.
All dimensions and weights are approximate. Please see technical specification for more details and options.
