An improved toolholder for clamping an apertured cutting insert into an insert-receiving site in a forepart of a holder shank. A pin, received in the aperture of the insert, is fitted into a bore provided in the toolholder. A clamping plate and co-operating actuating means urge the insert against the pin. The clamp plate has a V-shaped pocket complementary to two converging edge surfaces of the insert, and on its lower surface is provided with serrations adapted to engage cooperating serrations on a fore portion of the holder shank.
