Our best SDS-plus multi-cutter with the longest service life in concrete and reinforcement.
The Trijet SDS-plus is the most powerful hammer drill bit from Heller and has the longest service life for concrete and reinforcement steel rebar applications. On the one hand, the patented Trijet drill head is characterized by its extremely robust and powerful drilling progress. On the other hand, it ensures maximum effectiveness and speed as well as minimum vibration when drilling due to its optimized helix design. In comparison to the other hammer drill bits, the Trijet SDS-plus has the lowest cost per hole. Tips and tricks for professional use: Click here for the Heller video tutorial
Premium multi-cutter for concrete and reinforcement
Highest service life and extremely resilient to wear
Particularly powerful and rugged multi-cutter with patented Trijet tip
With recessed carbide tip for extreme resilience in reinforcement steel and powerful drilling progress
Lowest costs per hole
Highest effectiveness and speed thanks to Trijet tip plus optimised helix design
Best possible drill dust transport without risk of inflagration thanks to large-volume, low-vibration Twinmax 3D helix, also in deep holes
Lowest vibration thanks to computer-simulated helix reduces the load on the user
Particularly easy positioning; avoids spalling even after drilling many holes thanks to double centring tip

Hammer drilling in concrete, sand-lime brick, natural stone, brickwork, clinker.
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.
