PURPOSE: To provide a cutter with angle cutting function which can feed, cut and out even shorter material automatically without manual help compared with the same type of cutter.

CONSTITUTION: A saddle 7 displaced being slided longitudinally in a material feed direction in relation to a base 1 by the driving of an actuator 6 is provided at the rear in the material feed direction in relation to a turning bed 3. A driving roller 8 displaced in an orthogonal direction to the material feed direction and rotated around a vertical axis is supported on the saddle 7, while the base 1 is provided with plural driven rollers 9...9 respectively rotatable around a vertical axis, along the material feed direction and in the position opposed to the driving roller 8. When material W is long, the driving roller 8 is rotated in the state of being pressed to the material W to feed the material W, and when the material W is short, the material W is held between the driving roller 8 and the driven rollers 9...9 in the retreat position of the saddle 7, and then the saddle 7 is advanced with the driving roller 8 in the stopped state to enable the conveyance of the material W.
