The 4Power Pro is Heller's best premium 4-cutter. The 4 cutting edges and 4 helixes ensure powerful and fast drilling progress in concrete and reinforcement. At the same time, the innovative 4-helix technology effectively removes the drill dust with minimal dust deflagration. Heller's SDS-plus 4-cutter 4Power Pro is particularly characterised by its resistance and proves to have an increased product life in both concrete and reinforcement. Thanks to the optimised head or carbide geometry, the 4Power Pro drills 10% faster in concrete, is 3x more robust in reinforcement and has a 2x longer service life compared to its predecessor. The new, patented double-centre tip made of carbide also ensures more stable and precise drilling, making drilling as user-friendly as possible.
