4Power Pro SDS-plus
Hammer drill bit with 4 cutting edges combines speed and robustness.
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.

Heller is the first manufacturer specialising exclusively in drill bits to test its products in an independent institute for the adverse effects of drilling vibration. If a rotary hammer is integral to the application, it can be expected that so-called “hand-arm vibration” could have some form of long term effect on the users health. The “EU Vibration Directive 2002/44/EC” aims to help, in that it stipulates the maximum vibration to which users may be exposed. Lowvibration power tools are called for in addition to low-vibration techniques – but low-quality drill bits can also have an adverse effect. Low cost, poorly designed drill bits can reserve the effect of low vibration power tools. Heller drill bits demonstrated optimal effectiveness and extremely low vibration in the practical tests. In fact, they even distinctly reduced vibration.
The special technique of hardening by blasting makes for the perfect surface finish: the probability that a Heller hammer bit will break under very high loads is extremely low – even on impact with reinforcements. Ideal, especially with long dimensions: HST hardening guarantees high bending flexibility without breaking.
