Claims

[Scope of utility model registration request]

A handpiece that injects water and air from one or more injection ports provided at the bottom of a head case of the handpiece to the tip of a cutting tool attached to the head case to cool the cutting tool and the treatment area. In the turbine housing, when mounted on the lower part of the head case, at least the outer peripheral surface and bottom surface of the lower bearing are covered, and a gap for a wind passage is formed between the turbine housing and the head case, and a water supply on the outer peripheral wall surface. A groove is recessed therein, and one or more injection holes penetrating from the bottom surface through the water supply groove to the upper surface are bored, and when installed in the lower part of the turbine housing, the upper surface and the turbine housing are connected. A handpiece characterized in that it is equipped with a jetting body having a gap for an air passage formed therebetween.
