PCT No. PCT/SE92/00286 Sec. 371 Date Oct. 29, 1993 Sec. 102(e) Date Oct. 29, 1993 PCT Filed May 4, 1992 PCT Pub. No. WO92/19403 PCT Pub. Date Nov. 12, 1992.In a tool arrangement, an end part of a holder shaft is provided with a seat which provides a stable support for a cutter insert in at least two of the principal directions utilized in a machining operation. Stresses imposed on the cutter insert during the machining operation are transferred in an effective fashion to the shaft. The arrangement includes at least one tightenable fastening device which, after tightening, engages with the cutter insert and forces it against at least one surface of the seat. The cutter insert has stop parts with which the fastening device is intended to engage only after the cutter insert, through displacement relative to the seat on the shaft and whilst the cutter insert still in contact with the seat, has reached its operating position.
