Abstract
A cutter-tooling assembly has a tool holder, a positioning chunk, a cutter and a collet. The tool holder has a through hole axially formed through the tool holder. The positioning chunk is screwed in the through hole and has a cavity. The cavity has multiple corners formed around an inner surface of the cavity. The cutter is inserted into the through hole and has multiple edges abutting the corners. Because the cross sectional shape of the cavity is multilateral and has multiple corners which the edges abut, the combination of the corners and the edges can prevent a relative rotation between the tool holder and the cutter and make the cutter securely connected with the tool holder.

A cutter-tooling assembly comprising:
- a cylindrical tool holder having
- a connecting section;
- a collet section opposite to the connecting section;
- a flange section located between the connecting section and the collet section;
- and
- a through hole formed axially through the connecting section, the flange section and the collet section;
- a positioning chunk mounted securely in the through hole of the tool holder and having
- a first end;
- a second end opposite to the first end of the positioning chunk;
- an external threaded part formed around the first end of the positioning chunk and screwed in the through hole of the tool holder;
- and
- a cavity axially formed in the second end of the positioning chunk and having
- a non-circular cross section;
- an inner surface;
- and
- multiple corners formed around the inner surface of the cavity at intervals;
- a cutter inserted into the through hole of the tool holder and having
- a cutting area located outside the collet section;
- a fixing area being opposite to the cutting area and having an outer surface and multiple edges which are formed on the outer surface of the fixing area and abut the corners;
- and
- a shank formed between the cutting area and the fixing area;
- and
