There is described a new bending and squeezing blade for sheet metal bending machine. The blade comprises a bending tooth provided with a head surface that is suitable to engage the edge of a sheet metal to carry out its bending at 90° and with a foot surface that is suitable to engage the 90° folded edge of the sheet metal to carry out its additional bending at an angle greater than 90° and its possible squeezing on the remaining part of the sheet metal up to art angle substantially equal to 180°. In order to assure the locking of the sheet metal during the operation of squeezing the machine preferably comprises a blank holder provided with a pressing member, that can be controlled so as to project from the support foot of the blank holder in order to lock the sheet metal on a fixed counter blade.
