Work with daylight quality
As the undisputed leader in LED technology, W&H has developed surgical contra-angle handpieces with mini LED+, which offers outstanding illumination with high-contrast, natural light.
Your advantages at a glance
- Natural reproduction of red tones
- Independent power supply with integrated generator
- Fatigue-free working thanks to optimal ergonomics
- Durable and robust due to high-quality stainless steel and scratch-resistant coating
- Can be dismantled for thorough cleaning
- Thermo washer disinfectable and sterilizable
Fatigue-free working thanks to optimal ergonomicsFatigue-free working
The ergonomic design is perfectly coordinated to all the application possibilities and prevents fatigue.
Perfect light due to mini LED+Optimal illumination
Thanks to its being half the size of a normal LED, the mini LED+ can be integrated very close to the contra-angle head and offers optimal illumination. With its neutral white light our LED provide a superior light source. This allows you to have daylight quality light in the treatment area regardless of whether you have an optic or non-optic drive system.
Independent power supplyIndependent power supply
As soon as you activate your contra-angle handpiece, the generator turns.It autonomously generates the electricity needed for the mini LED+ regardless of the type of drive system you work with.
Scratch-resistant surfaceScratch-resistant surface
The unique coating protects the contra-angle handpieces from scratches. This facilitates cleaning and preserves the value.
Can be dismantled without toolsPerfect cleaning – Can be dismantled without tools
To enable thorough cleaning to be carried out, the contra-angle handpieces can be easily and quickly dismantled and re-assembled – without the use of tools.
Cleaning parts individually provides the most effective result.

Indications
e.g.: hemisection, extraction of wisdom teeth
Surgical contra-angle handpieces with 45° head
For tight squeezes
The contra-angle handpieces with 45° head unite the advantages of straight and contra-angle handpieces for the first time.
This is particularly helpful in the surgical extraction of wisdom teeth, precise tooth separations and apical resections.
Depending on the drive speed, the ratio of 1:2.7 makes it possible to achieve speeds of up to 135,000 revolutions per minute on the rotary instrument.Your advantages at a glance
- Considerably better visibility of the treatment site thanks to the 45° head
- Unite the advantages of a straight and contra-angle handpiece
- Makes the access to the maxillary and mandibular molars much simpler
- A 3x spray guarantees sufficient cooling of the rotary instrument and the treatment site
