Description
The Heller Trijet Ultimate SDS-plus is a multi-cutter hammer drill bit for concrete and reinforced concrete. Its patented Trijet tip carries cutting edges of equal height with reverse curvature, and the head includes reinforcement protection chamfers. A recessed carbide tip helps the head cope with reinforcement steel.
Behind the head sits a large-volume, low-vibration triple helix, designed to transport drilling dust out of the hole, including in deep holes. A double centring tip makes the bit easy to position and helps avoid spalling at the hole entry.
The Trijet Ultimate SDS-plus has an SDS-plus shank for hammer drilling. It is offered from 5 mm to 30 mm. Diameters from 22 mm up are built with multi-piece carbide.
Within the Heller range this is the premium SDS-plus multi-cutter. The Bionic Pro SDS-plus is the dual-cutter alternative. The Trijet Ultimate is also made in an SDS-max version, which is a separate product for SDS-max machines.
Key Features and Benefits
Trijet multi-cutter head
The patented Trijet tip is designed for powerful progress in concrete and resilience in reinforcement. Equal-height cutting edges with reverse curvature, plus reinforcement protection chamfers and reduced frontal surfaces, are aimed at keeping the head cutting through concrete and steel alike.
Triple helix for dust transport
The large-volume triple helix is designed to move drilling dust out of the hole, and the helix geometry is computer-simulated to lower vibration and reduce the load on the user.
Accurate starts
The double centring tip supports precise positioning and helps avoid spalling at the hole entry, even after drilling many holes.
Wide size range
Diameters from 5 to 30 mm cover small fixing holes through larger anchor and penetration holes, with working lengths up to 950 mm for deep holes. Multipacks and sets are also offered.
Applications and Use Cases
The Trijet Ultimate SDS-plus is suited to drilling in:
- concrete and reinforced concrete
- brickwork, brick and sand lime brick
- granite, marble and natural stone
Typical uses include anchor holes and fixings, services penetrations and drilling in heavily reinforced sections with an SDS-plus rotary hammer.

When a project means drilling again and again into reinforced concrete, the head design and the helix matter as much as the diameter. The Trijet Ultimate SDS-plus is Heller’s top-of-range SDS-plus bit for that work, and its size range runs from small fixings to 30 mm holes.
Global Source Middle East supplies the Trijet Ultimate SDS-plus to contractors and anchor installers in the UAE. Send the diameters and quantities for a quotation. For SDS-max machines, see the Trijet Ultimate SDS-max.
Frequently Asked Questions
Is the Trijet Ultimate SDS-plus the same product as the SDS-max version?
No. They share the Trijet design approach but are separate products with different shanks, size ranges and lengths. The SDS-plus version is made from 5 to 30 mm. The SDS-max version is made from 12 to 50 mm. Choose by the shank of your machine.
How does it differ from the Bionic Pro SDS-plus?
The Bionic Pro is Heller’s dual-cutter. The Trijet Ultimate is its multi-cutter with the patented Trijet tip, positioned as the premium bit for reinforced concrete.
Can it drill through reinforcement?
It is designed for concrete and reinforced concrete, with a recessed carbide tip and reinforcement protection chamfers. For work that is mainly about cutting through reinforcement steel, Heller also offers the Rebar Breaker SDS-plus.
Does it extract dust at the drill head?
No. Dust is carried out of the hole along the helix. For extraction at the drill head, see the Duster Expert SDS-plus.
