FIELD: medicine.
SUBSTANCE: invention concerns medical equipment. A dental engine tip is provided with a clamp in its front than tightened a shank end and mounted in a rotatable hollow shaft. Rotation is performed by means of an electric motor with its shaft being an extension of the hollow shaft. The joint adjacent ends of these two shafts are rotatable by a form-closure coupling. The adjacent ends of two shafts are both supported with the same inner race of a centre bearing. The coupling is provided in the specified inner race wherein the sliding shaft end of the electric motor is mounted, while being axially spring-loaded.
EFFECT: decreased length of the tip is reduced and manipulation accuracy by an operator, particularly by reducing loadings that a cable takes on back part of the tip.
