Hammer drill bit with 4 cutting edges combines speed and long life
The best SDS-plus multi cutter from Heller! The professional 4Power hammer drill bit with the SDS Plus shank is equipped with 4 carbide cutting edges and therefore enables quick and reliable drilling in concrete and reinforcement steel.
The robust cutting edges and the recessed carbide tips make the 4Power very resistant so that powerful drilling progress is even achieved when drilling into reinforcement steel.

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.
