Hammer drill set PROJAHN SDS-plus ECO, 5 pcs., for concrete/masonry/natural stone, Ø 6-12 mm

Don't let it get to you when working on concrete, masonry and natural stone and rely on the latest drill bit technology. The five-piece SDS-plus ECO set from PROJAHN contains hammer drill bits made of special tempered steel that is suitable for the hardest materials.

The attachments allow the use with maximum drilling speed as well as precise and powerful working. The two-spiral geometry with its large conveying spirals reduces friction and supports rapid removal of the drill dust.

The protruding tip enables precise spot drilling. The spiral is core-reinforced so that it remains maximally fracture-resistant even under extreme conditions. At the same time, the special design reduces vibrations, which is pleasant for the user and at the same time protects the machine.

The drills also have capping marks that indicate whether the tool can still be used to drill holes suitable for dowels. With the aid of the PGM test mark, you can ensure that the drills produce accurately fitting dowel holes and that there is precise concentricity. The 5-piece set includes drill bits ranging in size from Ø 6 to 12 mm.
