A cutter unit for mounting to a slide on a spring coiling machine, comprising a holder having an arm portion, extending along a first direction, for mounting to the coiling machine and a head portion extending along a second direction perpendicular to the first direction and defining an adjustable bore having an axis which extends in a third direction perpendicular to the first and second directions. A plug is insertable coaxially within the adjustable bore and sized to provide axial and rotational degrees of freedom within the bore. The plug includes a front face having a slot oriented transversely to the axis of the bore and sized to receive a cutting tool, and screws or the like for fixing the tool in the slot. A bolt or the like is carried by the head portion, for adjusting the bore to selectively permit axial and rotational movement of the insert therein, and to prevent said movement.
