ABSTRACT:
A right angle drill (1) includes a motor housing (6) which defines therein a hole (18) for accommodating a motor field system (3), a cut-out (15) formed in the underside of the motor housing (6) from the front end toward the rear of the tool (1), and a light unit (16) slidably fitted in the cut-out (15). The light unit (16) is a plate member having an arcuate cross section so as to define an inwardly curved rear (i.e., inner) surface (16a) along its entire length. The unit's inner surface (16a) conforms to the inner surface of the accommodating hole (18) of the motor housing (6). The light unit (16) additionally includes a protrusion (17) at the front outer surface thereof. Furthermore, the protrusion (17) contains a pair of LEDs (21) for illuminating objects below an output spindle (12) to which a bit can be attached.
