Trijet Ultimate SDS-max
Our premium multi-cutter for reinforced concrete with best performance.
The Trijet Ultimate SDS-max SDS-max hammer drill bit is Heller's premium multi-cutter for reinforced concrete with best performance. The hammer drill with SDS-max connection guarantees maximum effectiveness, robustness and speed in concrete and reinforcement. With its distinctive, patented double-centre point, it ensures easy, precise spot drilling. The embedded, solid carbide head is up to 4 times more robust compared to competitor products. At the same time, the innovative, backward-curved cutting edges of the Trijet Ultimate SDS-max cut through reinforcement easily and without snagging. The powerful hammer drill not only demonstrates powerful performance and robustness, but also impresses with its speed: The Trijet Ultimate SDS-max drills up to 10% faster than its already market-leading predecessor. Thanks to the new helical design with optimised drill dust grooves, the drill dust transport has also been improved to ensure fast and easy drilling progress.

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.
All drill bits by Heller have the independent PGM certificate, assuring safe connection systems.

Patented spiral forms guarantee – for example, by means of an alternatively narrow and wide back edge – optimum removal of dust without any blow-outs. Extremely high speed with ideal transmission of impact energy thanks to computer-aided design. In addition, Heller hammer drill bits are outstanding for quiet, low-vibration operation.
