Core drilling in locations where space and power are limited

Published on 23 July 2026 Reading time : 3 minutes

When performing maintenance, renovation, and assembly work on steel structures, core drilling isn’t always easy. Space is often limited, there’s no fixed power supply, and the work site can be difficult to access. Think of work under bridges, between steel H-beams, or in existing structures where there’s little room to maneuver.

It is precisely in such situations that a compact, cordless solution proves practical. With the Nitto Kohki CLO-2725, Van Dulst offers an angle core drill that runs on a specialized 36V Multi Volt battery from HiKoki. This combination allows professionals to work flexibly on-site without relying on cables or a fixed power supply.

Practical for bridges and steel structures

A key application for this machine is maintenance and renovation work on bridges, fixed crossings, and other steel structures. At these types of locations, a power source isn’t always nearby. Working with long cables is cumbersome and can make the worksite unnecessarily unsafe or cluttered.

With a battery-powered core drill, a technician can work directly at the right spot. This is useful, for example, when modifying existing steel structures, installing mounting points, or replacing parts during renovation work.

A compact machine also offers advantages when working at heights, on scaffolding, or in hard-to-reach areas. The CLO-2725 is easy to transport to the worksite and does not need to be connected to a fixed power source.

Designed for limited space

While many core drilling machines operate in an upright position, the Nitto Kohki CLO-2725 features an angled design. As a result, the machine has a lower profile and is better suited for use in areas where there is limited space above the material.

Think of work between steel H-beams, under floor structures, inside machine frames, or on existing steel structures where a standard core drill won’t fit. In such situations, an angled core drill can prevent the need to resort to a less practical drilling method.

This makes the machine an attractive option for steel fabricators, maintenance teams, assembly companies, and contractors who regularly work on-site.

Cordless operation without compromising on performance

Cordless tools are increasingly being used in situations where flexibility is key. Not only because cords can be cumbersome, but also because work can begin more quickly when there’s no need to locate or set up a power source.

The CLO-2725 runs on a 36V Nitto Kohki battery and is suitable for core drilling in steel. This makes the machine suitable for a wide range of tasks where mobility and performance must go hand in hand.

The Nitto Kohki battery is specifically designed for this machine, ensuring reliable control and optimal performance during core drilling. For professionals working on-site, this means the machine is always ready to go without compromising drilling capacity.

A practical solution for on-site work

The CLO-2725 demonstrates that core drilling doesn’t always require a large machine or a fixed power source. Especially in areas where space is limited and flexibility is essential, a battery-powered angle core drill offers a practical solution.
