ENDURO Trijet SDS-max

hammer drill bit

Our best SDS-max hammer drill. Powerful, fast & durable Take the fight to concrete and reinforcements!

The Enduro Trijet SDS-max hammer drill bit (available with a diameter of up to 16 mm) perfectly unites speed and robustness - even in reinforced concrete. The embedded carbide tip makes this drill bit extremely resilient. Users also benefit from very low vibration and especially easy positioning.

With recessed carbide tip for extreme resilience in reinforcement steel and powerful drilling progress

Maximum effectiveness and speed thanks to the stable tips 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 and avoids spalling even after drilling many holes

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.

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.
