Abstract
A dental hand instrument comprises an elongated handle formed of a thermosetting plastic and a metal working tip inserted into an end of the handle. The handle may be a multi-part assembly with replaceable working tip end sections. The handle has a bore provided in the end to accommodate a shank end of the tip. The handle and the tip are subjected to heat treatment to partially melt a portion of the thermosetting plastic adjacent to the shank end to bind the shank in solid plastic-to-metal contact along the shank end. The shank end of the tip is provided with a non slip surface that is encompassed and embedded in the thermosetting plastic so that the tip will not turn during use.
