The carbide hammer drill from Heller, with a diameter of 12 mm, is a highly advanced tool specifically designed for demanding drilling tasks in various materials. With its patented cutting design based on the bionic principle, this hammer drill offers outstanding performance and efficiency. The Twinmax-3G spiral ensures optimal transport of the drill dust, which increases drilling speed and extends the tool's lifespan. The smooth drill operation and optimal impact energy throughput enable precise and effective drilling in concrete, masonry, natural stone, tiles, marble, and clinker. The HST-hardened surface reduces the likelihood of breakage when hitting reinforcements, further enhancing the drill's reliability. With an overall length of 1400 mm and a working length of 1350 mm, this hammer drill is ideal for professional applications.
