The SDS-plus cordless rotary hammer drill is a versatile tool for assembly and construction work, combining efficient drilling with impact, non-impact drilling, and chiseling. It is useful for installing dowels, making holes for installations, and precise chiseling in hard-to-reach areas. Four operating modes allow you to adjust the work to the material - from classic drilling in wood and metal, through impact drilling in concrete and brick, to chiseling with the ability to set the chisel in the most convenient position.
The brushless motor provides constant power even during prolonged work, which is important when drilling a series of large diameter holes. The efficient impact mechanism with an energy of 2.5 J ensures fast progress in harder substrates, including concrete with large slabs, lintels, and cobblestones.
The design based on an 18 V Li-Ion battery power offers total mobility, long operating time, and stability and continuity of work thanks to fast charging. The SDS-plus handle allows for quick accessory changes, and the built-in LED lighting makes work easier, especially in installation shafts and poorly lit rooms. The set includes an additional handle and a depth limiter, increasing control and accuracy during drilling. The low weight makes working overhead or in forced positions less tiring.
The tool is available in three battery equipment variants, making it easy to adapt to the user's needs.
