A metal-cutting tool comprises a holder, a clamp, and a metal-cutting insert. The holder includes a blade part which forms an upwardly facing seating surface extending in a front-to-rear direction. The holder includes a recess including 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. The insert is mounted on the seating surface and the clamp has a rear portion which is slidable within the recess, whereby a front portion of the clamp pushes downwardly and rearwardly against a top surface of the insert. That top surface is shaped so that the front portion of the clamp is flexed upwardly relative to the rear portion when the rear portion is pushed rearwardly to the clamping position.
