The hammer drill from Heller, with a diameter of 28 mm and a total length of 250 mm, is a powerful tool specifically designed for demanding drilling tasks in hard materials such as concrete, stone, masonry, marble, and clinker. Equipped with an innovative Y-Cutter cutting profile, this drill offers improved cutting performance and smooth operation, resulting in high drilling speeds. The ergonomic design of the drill protects joints and muscles, making it particularly user-friendly. The Twinmax spiral ensures optimized impact energy transfer, while the HST-hardened surface increases break resistance during hammer drilling and enhances strength when hitting reinforcements. This hammer drill is therefore an ideal choice for professional craftsmen and DIY enthusiasts who value quality and efficiency.
