100 cc Motor
The DOA AK50-100cc - Hand-guided hydraulic core drilling machine D=125-250 mm (underwater version) is a powerful specialised tool for precise underwater core drilling. Equipped with a 100 cc hydraulic motor, the machine is ideal for large drilling diameters up to 250 mm - for example for foundation work, pipe construction or maritime construction projects.
Thanks to the compatible standard mount for drill rigs, the AK50-100cc can be guided precisely. A special highlight: The hydraulic motor is interchangeable, which enables a high degree of adaptability with low operating costs. Depending on the drilling diameter and the hydraulic power, the device achieves 300 min-¹ at Ø 130-250 mm (30 l/min) or 380 min-¹ at Ø 125-180 mm (38 l/min).
The machine operates in the hydraulic range of 30-40 l/min at 200 bar, with a permissible back pressure of 90 bar. An integrated water connection, a robust mandrel (1-1/4" external / 1/2" internal) and the well thought-out, modular design make the AK50-100cc a reliable tool for professional immersion applications.
With compact dimensions of 54 × 22 cm and a weight of 13 kg, it is robust but handy - ideal for mobile use under water. The DOA AK50-100cc is available from KW Hydraulik - your specialist for hydraulic drilling technology and underwater applications with technology from DOA.

Our hydraulically operated underwater tools have been developed for the most demanding applications at depths of up to 30 metres. Thanks to specially coated, corrosion-resistant materials, they are ideal for use in salty environments, such as those found in offshore wind farms, harbour maintenance or maritime construction projects. The sophisticated design allows safe and precise handling - even with thick neoprene gloves, as is common in professional diving applications.
A decisive advantage of our systems lies in their high modularity and system compatibility: the tools can be operated flexibly with different hydraulic power packs - ideally with the hydraulic power packs from our range, which are specially designed for mobile or stationary use in underwater applications. We also offer high-pressure hydraulic hoses in various lengths and specifications - with salt water-resistant sheathing and matching quick-release couplings on request.
What requirements must underwater tools fulfil?
Tools for underwater use are subject to extreme loads: Pressure, temperature, corrosion and difficult visibility conditions require robust designs and absolutely reliable function. Our products consistently fulfil these requirements - thanks to tightly encapsulated hydraulic components, maintenance-friendly design and high mechanical resilience. Especially in critical applications - such as cutting reinforcements or drilling in underwater concrete - trouble-free operation is vital.
All underwater tools are tested by us before delivery. Our internal standards go beyond the usual requirements. Find out more about our certified quality management in accordance with ISO 9001:2015.
You can rely on our many years of experience, tested technology and personalised advice - for safe underwater work.
