Tool for grooving and parting and method of manufacturing same

A method of manufacturing a holder and a clamp of a metal-cutting tool, comprising the steps of:

• A) machining an upwardly facing seating surface in a blade part of a holder by a profile milling cutter, whereby the seating surface extends in a front-to-rear direction, and is adapted to support a metal-cutting insert;
• B) machining a recess in the holder by the same profile milling cutter as used in step A, whereby the recess has a longitudinal axis extending in the front-to-rear direction at an angle relative to the seating surface, whereby an imaginary rearward extension of the seating surface converges toward the axis, a front end of the recess being milled at a higher location than a rear end of the seating surface, to form a generally upright contact surface extending from the rear end of the seating surface to the front end of the recess and against which a rear end of a cutting insert is adapted to engage;
• and
• C) providing a clamp including front and rear portions, the rear portion being shorter than the recess and slidable within the recess along the axis thereof between a rear clamping position and a front releasing position, the front portion including a downwardly facing clamping surface forming an angle with the longitudinal axis of the recess, the clamping surface overlying the seating surface and adapted to clamp a cutting insert to the blade by pulling the cutting insert against the contact surface.
