Abstract

A power tool with a chuck and a tool body having a housing, a motor received in the housing, a light array mounted to the housing, and an output spindle extending through the light array and which is rotationally driven by the motor. The chuck has a chuck body, a plurality of jaws, and an outer sleeve. A rear end of the chuck body is rotatably mounted on the output spindle. The chuck body has a plurality of jaw apertures and a plurality of light holes. The jaw apertures and the light holes extend through a front surface of the chuck body. Each of the jaws is received in a corresponding one of the jaw apertures. The outer sleeve is disposed about the jaws and the chuck body. Light emanating from the light array is transmitted through the light holes to illuminate a zone in front of the chuck body.

Claims

1. A power tool comprising:

a tool body having a housing, a motor received in the housing, a light array mounted to the housing, and an output spindle extending through the light array and rotationally driven by the motor; and

a chuck having a chuck body, a plurality of jaws, and an outer sleeve, a rear end of the chuck body being fixedly mounted on the output spindle for common rotation with the output spindle about a rotational axis, the chuck body having a plurality of jaw apertures and a plurality of light holes, the jaw apertures and the light holes extending through a front surface of the chuck body, each of the jaws being received in a corresponding one of the jaw apertures, the outer sleeve being disposed about the jaws and the chuck body, wherein light emanating from the light array is transmitted through the light holes to illuminate a zone located in front of the chuck body.

2. The power tool of claim 1, wherein the light holes are inclined relative to the rotational axis.

3. The power tool of claim 1, wherein the light array comprises a plurality of light sources.

4. The power tool of claim 3, wherein the light array has a first quantity (N) of the light sources, wherein the chuck body has a second quantity (n) of light holes, and wherein the first quantity (N) is greater than the second quantity (n).

5. The power tool of claim 4, wherein the first quantity (N) is greater than or equal to twice the second quantity (n).

6. The power tool of claim 1, wherein the chuck is a keyless chuck.

7. The power tool of claim 1, wherein the light array is selectively operable through actuation of a dedicated switch mounted to the tool body.

8. The power tool of claim 1, wherein the chuck further comprises at least one optical element received in each of the light holes.

9. The power tool of claim 8, wherein the at least one optical element comprises a lens.
