A pneumatic angle grinder having an improved grip structure to solve the problem that the holding posture is not ergonomic when the wrist is lifted. When a press handle is pressed downward to the bottommost, a rear section of the press handle is lower than a front section thereof. The rear section is substantially flush with a tail portion of a cover. A depression is formed above a bent section and the rear section of the press handle and the tail portion of the cover relative to the height of the front section. When an operator grasps a head portion of a main body, the thenar and the hypothenar of the operator lean against the cover. The location of the depression to rest the bottom side of the wrist is significantly lower than the top end of the head portion for the wrist to move downward.
