The invention discloses an electric drill facilitating drilling of an inclined hole. The electric drill comprises a machine body assembly and an angle adjusting assembly. The angle adjusting assemblyis mounted on a machine body of the machine body assembly through a sleeve with rods in a sleeving mode; the sleeve with the rods is arranged on the rear side of the angle adjusting assembly; and themachine body assembly further comprises a rear cover, a motor gland, a middle moving block, sliding covers A, springs B, a cushion block, a drill bit, sliding covers B, springs C, springs A, a front cover, a cutting liquid storing cavity and bent holes. The electric drill is provided with the angle adjusting assembly, so that drilling of the inclined hole is facilitated; cutting liquid storing holes are formed inside the machine body, when the drilling action is conducted, the air pressure between the front cover and the machine body is increased, a gap between the drill bit and the front cover is small relative to holes in grooves of the middle moving block, and therefore, cutting liquid flows out from the front end of the drill bit under the effect of the air pressure and takes the cooling and lubricating effects; when the motor stops rotating, the middle moving block stops moving, the drill bit stops rotating, the sliding covers A and the sliding covers B reset under the effects ofthe springs B and the springs C, and the cutting liquid does not flow out any more; and thus convenience is achieved.
