Tornado LK is an air-driven, high-speed handpiece with an built-in LED light. The turbine contains ceramic bearings, extending the life of the turbine and reducing the noise level during use. The small head results in improved access and is sealed to help prevent contamination and increase bearing durability. Tornado LK has a four-port symmetrical water spray, a non-slip scratch-resistant coating, and weighs just 58
grams. It operates at 30 Watts and 55 dB and is attached to the lines using a multi-flex, Kavo-style coupler, and is available to fit Bien-Air
style couplers. Tornado LK comes with up to a 3-year warranty.

Unique Features

Tornado LK is designed with SteadyTorque technology, delivering a power output of 30 watts, due to the engineering of the rotor’s micron-precise shape and configuration, coupled with optimal air pressure distribution and exhaust flow. It also features Accu-Chuck PreciPlus, a vibration-canceling bur-retention mechanism, allowing for easy bur-release and removal, and ultra-quiet operation. Lastly, it features Cool Touch, a patented anti-heating feature designed to maintain the instrument’s head at a safe temperature, thus significantly decreasing patient burn injuries.
