ABSTRACT:
A holder for turbine-driven dental tools such as drills. The holder is made of two-parts comprising an elongated shank and an anglepiece having a head in which is mounted an air-driven turbine for driving the dental tools. Provision is made by a coupling structure for attachably coupling the anglepiece to the shank. A finger-grip sleeve is provided on the coupling structure that allows the holder to be held in position while angularly positioning the holder angularly at set angular positions relative to the sleeve. The operator can thus hold the holder at a desired position and still rotate the anglepiece angularly by rotating the shank about its axis.
