AeroPerformance Blade TechnologyThe HE21KL is powered by MK-Dent’s AeroPerformance blade system, designed to provide strong torque, reliable precision and long service life.Proprietary laser balancing technology during manufacturing helps create smooth turbine rotation, while the stainless steel insert inside the bur guide supports stability and durability during high-speed operation.With up to 24W of power, the turbine delivers the cutting performance needed for everyday restorative and preparation work.Ceramic Bearing PerformanceThe turbine uses ceramic bearings designed to withstand the demanding conditions of clinical use, including high rotational speeds, cleaning fluids and repeated sterilisation.Paired with a corrosion-resistant cage and refined lubricant formulation, the bearing system supports quiet, smooth and durable performance over time.Integrated Glass Rod Fibre OpticsThe HE21KL includes glass rod fibre optics for enhanced visibility at the treatment site.When used with compatible MK-Dent LED or Xenon couplings, the fibre optic system delivers up to 40,000 lux of glare-free illumination.With a 5500K colour temperature, the light is designed to provide colour-accurate visibility of the preparation area.Smooth Eco Body DesignThe Eco Line body features a smooth chrome-coated surface designed for durability and easy handling.Its scratch-resistant finish helps maintain a professional appearance during daily use, while the re-profiled air inlet ports improve airflow into the head chamber to help power the AeroPerformance blade system.Quiet and Efficient Clinical OperationWith a sound level of 62 dB and a lightweight 63g body, the HE21KL supports comfortable use throughout busy clinical sessions.The push-button back cap allows quick bur changes, while the standard head size provides a practical combination of access, stability and visibility.Effective Cooling with Mixed SprayFour asymmetrical mixed spray ports provide effective cooling across the treatment area.This spray design helps protect the bur and tooth structure during preparation while maintaining clear visibility.Broad Coupling CompatibilityThe HE21KL is available for several major coupling systems, allowing it to integrate into a wide range of dental units and existing handpiece setups.Compatible coupling options include:KaVoSironaNSKW&H
