The perfect hammer drill bit for extreme requirements in concrete and natural stone. The ProXtreme from Heller impresses with its long service life, excellent positioning behavior, and strong performance. The optimal tip geometry and the high-volume helix design enable very high speed drilling. Thanks to the ground carbide tip and high-strength brazed joint, the ProXtreme can be used in a wide range of applications. Furthermore, the blasting technique used by Heller ensures extremely good performance characteristics and high break resistance. This drill bit also has a "Tri" shank to prevent the bit slipping in the chuck.
