In modern geotechnical engineering, water well drilling and blast hole construction, DTH Drilling is more and more favored by the market with its advantages of high efficiency, low energy consumption and strong adaptability. This article will focus on several small DTH drilling machines, covering technical parameters, product advantages, typical application scenarios and FAQ, to help you better understand and purchase the suitable Portable DTH drilling machine.
The SKD70 is a compact and efficient hybrid DTH drilling rig that combines electric motor power with compressed air technology. The motor provides strong rotational torque, driving the reducer and rotating the drill pipe, while the compressed air powers the impactor to deliver continuous rock-breaking force. As the alloy drill bit penetrates the rock, the crushed debris is blown out through the drill bit’s air vents and discharged to the surface.
Designed for versatility and high efficiency, the SKD70 drilling rig is lightweight and highly maneuverable—ideal for narrow construction sites and rugged hillside projects. It is widely used in slope stabilization, highway excavation, and railway construction. With its energy-saving design and reliable performance, the SKD70 is a cost-effective solution for small DTH drilling operations. Whether you’re working in tight urban spaces or challenging terrains, this small DTH drilling machine delivers powerful results with minimal site impact.
The SKQ100 DTH drilling rig is a pneumatic-powered machine that uses compressed air to generate mechanical force for efficient rock breaking. Driven by a reliable air motor, the SKQ100 can operate without electricity, making it safe and suitable for remote or underground environments.
Designed specifically for tunnel and underground engineering, the SKQ100 column-type drilling rig features an adjustable vertical column and a 360-degree rotatable rig base for flexible drilling angles. Depending on the site requirements, it can be equipped with either a long carriage (for 1-meter drill pipes) or a short carriage (for 0.5-meter drill pipes), both utilizing upper and lower telescopic cylinders for smooth operation.
Ideal for water conservancy, road and railway construction, and mining projects, the SKQ100 is a versatile and efficient solution for demanding drilling conditions.
