A variable output type metal bead device for hammering is provided to control the metal bead batting intensity of solenoid by controlling pulse length of the excitation voltage. A metal bead device for hammering comprises: a solenoid part for striking the metal bead; a drive voltage generation unit for supplying the applied voltage of solenoid; and a switching controller for controlling solenoid. The solenoid part(100) comprises a bobbin(101), an excitation coil(102), a plunger(103), and an extension spring(104). The plunger arm(105) of the base metal and the high elastic impact spring head(106) are mounted in the plunger in order to strike the metal bead.
