The Einhell HM hollow drill crown with SDS-Plus shank and a diameter of 82 mm is ideal for powerful drilling work in concrete, masonry, and stone. Thanks to its robust construction with eight carbide teeth, as well as two 10-mm discharge holes and a grooved outer surface, drill dust is reliably channeled away, allowing for continuous work progress. The integrated 8-mm centering drill with a four-cutter carbide plate ensures a clean drilling start and precise results. The stable M22 threaded connection provides a durable link between the drill crown and the SDS-Plus shank. The latter allows for tool-free compatibility with all common SDS-Plus rotary hammers. The HM drill crown is therefore the optimal solution for precise drilling in renovation and installation work – suitable for both DIY enthusiasts and professional use.
