Abstract: A dental hand instrument (10), comprising a handle (11) with parts (12a, 12b) at its ends. The end of each neck part is provided with a coupling element (15) designed for the connection of replaceable tips (20) and oriented in the same direction with the neck part. The coupling element is a socket or pin (19) extending in the same direction with the neck part and allowing a corresponding concentric pin (21) or socket (26) of the tip to be fitted into/onto it. The socket of the coupling element may be provided with slots (17), and the inner surface of the socket has a circular or cornered cross-sectional form. The neck part and coupling element of the hand instrument are preferably made of stainless steel and the tip is made of steel, aluminum, plastic-coated aluminum, steel or titanium.
