Abstract
A dental handpiece assembly comprising a handgrip and a detachable headpiece. The front end of the handgrip includes an arm that extends forward and below the headpiece. The headpiece carries a dental tool and the handgrip supplies cooling water and air through the extended arm to outlets close to the tool. This arrangement has the advantage that the detachable headpiece does nto need to include passageways for the cooling water and cooling air.
