CDM 20 S

Powerful and compact. The hand-held power tool for breakthroughs in masonry and concrete inspires with particularly ergonomic handling and consistently strong performance.

The hand-held core drilling machine for wet drilling with a spade handle impresses with its particularly compact, light and ergonomic design, which promotes effortless working. The adjustable clamping handle enables easy and controlled operation during hand-guided core drilling. The high-torque 230 V motor achieves a nominal power of 2,000 W and enables core drilling in masonry up to 200 mm diameter and in concrete up to 150 mm diameter.

The powerful and durable core drilling system works with a diamond drill bit and is suitable for a variety of tasks such as wall breakthroughs, wall drilling and floor drilling. The hand-held Core drill is an extremely efficient tool for a wide range of applications in installation and fastening technology applications. Three gear ranges allow optimal speed selection, matched to the core drilling diameter. Precise horizontal and vertical core drilling is guaranteed by the three integrated water levels. The hand-operated core drilling machine is equipped as standard with the extremely effective MULTI-TRONIC. The sophisticated, tried and tested overload protection system ensures maximum ease of use and a long life for core drilling motor. One electronic and one mechanical overload clutch and additional thermal overload protection guarantee the maximum safety in demanding long-term use.

Ergonomics and power impress with this robust, hand-held core drilling system. Explore the features of the CDM 20 S:
