ELECTRIC TOOL

An electric tool capable of improving sharpness of tip blade without replacing tip blade is provided. The electric tool (1) includes a tip blade (3), an oscillating rotation mechanism (6) configured to rotate the tip blade (3) back and forth around a rotation axis part (61), a motor (7) configured to drive the oscillating rotation mechanism (6), a battery mounting part (26) and a control circuit (8). The battery mounting part (26) allows any one of battery packs (4), each of which is configured to supply electric power to the motor (7) and has different battery performances, to be detachably attached to. The control circuit (8) is configured to receive electric power supplied from the battery pack (4) attached to the battery mounting part (26) to the control motor (7), and, as the battery pack (4) attached to battery mounting part (26) has a higher battery performance, so as to rotate the motor (7) at a higher speed, thereby rotating the tip blade (3) back and forth at a higher speed. 能够在不替换顶端刀片的情况下改善顶端刀片锋利度的
