The invention relates to a tool head having a shrink-fit chuck (10) that has an axial receiving hole (22), and having a tool (12) that is insertable by way of its cylindrical tool shank (24) into the receiving hole (22), which is open at the front end of the shrink-fit chuck (10), and is fixable therein by thermal shrinking of the shrink-fit chuck (10). According to the invention, it is proposed that the shrink-fit chuck (10) has, in its front end portion, an annular recess (30) that radially widens the receiving hole (22) and is open at the end side, and that a function ring (14) is positioned on the tool shank (24), wherein, in the shrink-fitted state, the tool shank (24) is frictionally fixed in the receiving hole (22) and the function ring (14) sits at least partially in the annular recess (30). |
