Hole Diameter: 90-219 mm
Hole depth: 0-70 m
Drilling Method: Air Drilling
>> Application
The SP619 is a compact yet powerful down-the-hole drilling rig designed for flexible deployment across diverse drilling environments, tailored for shallow large-diameter hole applications. Its capable structure and high adaptability make it ideal for manifold construction, geothermal drilling, small-scale quarries, and pipeline foundation projects. Supporting a wide hole diameter range from φ90 to φ400 mm, it is highly versatile across unconsolidated layers and mixed formations.

PRODUCT DESCRIPTION
>> Characteristics
Robust Power & Fuel Efficiency:
Equipped with an optional Yuchai or Cummins engine, delivering stable output. The large 250-liter enclosed fuel tank extends working hours and reduces refueling frequency.
High-Performance Rotary & Feed System:
The high-torque rotary head delivers up to 13,000 N·m with a variable speed of 0-80 rpm. The motor-driven feed system offers a 5000 mm stroke and 18 kN thrust, providing reliable penetration.
Excellent Mobility & Terrain Capability:
The whole machine weighs only 6.0 tons with a compact structure. The crawler-type drive allows a tramming speed of 0-2 km/h and a 30° climbing capacity, coupled with 700 mm ground clearance, ensuring strong off-road capability on rugged job sites.
Wide Compatibility:
Suitable for both DTH Hammer and Auger drilling. Air compressor demand ranges from 15 to 50 m³/min and 1.0-2.4 MPa, ensuring compatibility with a wide range of pneumatic setups.
Centralized Control:
Rear-mounted centralized control system enables streamlined operation. The optimized layout improves operator visibility and access, ensuring a smooth workflow in confined environments.
