摘要 |
A boring tool comprises a tool holder fixed axially and with an oscillating rotation motion, arranged in an angle coupling head. This holder comprises a conic clamp maintained in a closed position by a pressure spring for the rotation-prevented reception of the handle of a dental boring tool for pulp canals. The driving of the tool holder is effected by the meshing of an excentric pin of a tail shaft in a radial opening of the outer envelope of the holder. The traversing clamp (10) is connected to the tool holder (2) at its rear end by a removable closure cap (16) which, in an operating position with the tool fitted in, goes beyond the end of the angle coupling head structure (1, 27). A pressure with the finger on the upper surface of said cap moves axially the tool holder and brings the clamp (10) in an opening position. |
