Description: Turbine handpiece TGL 637AM belongs to the group of turbines with light TGL 637. It is high performance turbine handpiece with celular or flexible light-guide, push button system of drill-bit fixation and three-jets cooling system. Turbine handpiece has built-in high quality ceramic bearings. Body of handpiece is fully produced from stainless-steel to minimize the weight of this dental instrument. The hygiene of turbine is secured by sterilisation at 135°C. The turbine is connected to dental unit via universal quick coupling KaVo MULTIflex 465LRN with light or its equivalent. Application: Turbine handpiece TGL 637AM belongs to the group of air-driven dental handpieces designed for dental treatment, especially for redrilling of enamel, opening of cavity, abrasion of teeth under crown and using a special tool accordance with special operating procedure for cutting up crowns and bridges as well. Optimal operating speed is recommended from 150.000 to 250.000 rpm. Advantages: The advantage of turbines TG /giga/ is their high performance, easy handling in the patient´s mouth and blowing of cavity directly by turbine handpiece /chip blower/. It is necessary to underline the high-alloy stainless steel body of turbine what is reflecting in high hygiene standard, durability and low weight of instrument. Three-jet’s spray is providing effective cooling of whole preparation space. Index „M“ means that connection of turbine handpiece with hose is realised via KaVo quick-coupling MULTIflex what allows to expand the range of connectable instrumets up to 50.
