The cutting tool of claim 13, wherein the central longitudinal axes of the plurality of light emitting diodes intersect an axis of rotation of the motor shaft at a point spaced away from the housing.17. The cutting tool of claim 13, wherein the plurality of light emitting diodes are turned on when the motor is activated.18. The cutting tool of claim 13, wherein each of the plurality of light emitting diodes emits a beam of light, and wherein the beams of light intersect at a point spaced away from the housing.19. The cutting tool of claim 18, further comprising a cutting accessory coupled to the motor shaft, wherein the beams of light illuminate at least a portion of the cutting accessory.20. The cutting tool of claim 19, wherein the beams of light illuminate at least a portion of the cutting accessory at a point of cut.21. The cutting tool of claim 13, further comprising an adjustable depth guide for setting a depth of cut of the rotary cutting tool.22. The cutting tool of claim 13, further comprising a rotary tool bit coupled to the motor shaft, the rotary tool bit having a helically-wrapped cutting edge.23. The cutting tool of claim 13, further comprising at least one air vent formed in the housing for directing a flow of air toward the point of cut.24. A hand-held rotary power cutting tool comprising:a housing having a motor provided therein, a shaft extending from a first end of the housing, the shaft being coupled to the motor and configured for coupling to a cutting accessory; at least two light emitting diodes mounted at the first end of the housing to direct light away from the first end of the housing and to illuminate a point of cut; wherein the at least two light emitting diodes each have a central longitudinal axis and are mounted such that the central longitudinal axes of the light emitting diodes are not parallel to a rotation axis of the cutting accessory. 25. The hand-held power tool of claim 24, wherein the central longitudinal axes of the at least two light emitting diodes are at an acute angle relative to a central longitudinal axis of the housing.26. The hand-held power tool of claim 24, further comprising means for attaching a cutting accessory to the shaft.27.
