A power driver may include a housing, a tool chuck and a power take off mechanism. The tool chuck may have an input shaft mounted for rotation on the housing. The input shaft may support chuck jaws. A chuck actuating shaft may be mounted for rotation on the input shaft. The power take off mechanism may be connected to the tool chuck. The power take off mechanism may be adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft. The transmission shaft may be a gear shaft axially aligned with the input shaft, or a tertiary shaft axially offset from the input shaft.

What is claimed is: 1. A power driver comprising: a housing; a transmission shaft mounted for rotation on the housing; a tool chuck having an input shaft mounted on the housing so that the input shaft is rotatable relative to the housing, the input shaft supporting chuck jaws, and a chuck actuating
What is claimed is: 1. A power driver comprising: a housing; a transmission shaft mounted for rotation on the housing; a tool chuck having an input shaft mounted on the housing so that the input shaft is rotatable relative to the housing, the input shaft supporting chuck jaws, and a chuck actuating shaft mounted for rotation on the input shaft; and a power take off mechanism connected to the tool chuck, the power take off mechanism being adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft. 2. The power driver as set forth in claim 1, wherein the transmission shaft is a gear shaft that is rotationally locked to the input shaft when the power take off mechanism is in the DRILL DRIVE MODE. 3. The power driver as set forth in claim 2, wherein the gear shaft is rotationally coupled to the chuck actuating shaft via a clutch. 4. The power driver as set forth in claim 1, wherein the transmission shaft is a tertiary shaft; and wherein the power take off mechanism includes a ring gear mounted for pivot action about the tertiary shaft. 5. The power driver as set forth in claim 4, wherein, when the power take off mechanism is in the CHUCK MODE, the tertiary shaft is rotationally coupled to the ring gear via a clutch. 6. The power driver as set forth in claim 4, comprising a mode ring mounted on the housing for rotation to pivot the ring gear about the tertiary shaft. 7. The power driver as set forth in claim 1, wherein the transmission shaft is a tertiary shaft; and wherein the power take off mechanism includes an idler gear mounted for pivot action about a power take off actuator shaft rotationally locked to the chuck actuating shaft. 8. The power driver as set forth in claim 7, wherein, when the power take off mechanism is in the CHUCK MODE, the tertiary shaft is rotationally coupled to the idler gear via a clutch. 9. The power driver as set forth in claim 7, comprising a mode ring mounted on the housing for rotation to pivot the idler gear about the power take off actuator shaft. 10. The power driver as set forth in claim 1, wherein the transmission shaft is a tertiary shaft; and wherein the power take off mechanism includes an idler gear mounted for pivot action about the tertiary shaft. 11. The power driver as set forth in claim 10, wherein, when the power take off mechanism is in the CHUCK MODE, the tertiary shaft is rotationally coupled to the idler gear via a clutch. 12. The power driver as set forth in claim 10, comprising a shift collar mounted on the housing for rotation to pivot the idler gear about the tertiary shaft. 13. The power driver as set forth in claim 1, wherein the power take off mechanism in the CHUCK MODE rotationally fixes the input shaft to the housing. 14. The power driver as set forth in claim 1, wherein the power take off mechanism is adjustable into a MANUAL OVERRIDE MODE to manually rotate the input shaft relative to the chuck actuating shaft. 15. The power driver as set forth in claim 1, wherein the chuck jaws are threadless chuck jaws. 16. A power driver comprising: a transmission shaft; a tool chuck having an input shaft mounted on a housing so that the input shaft is rotatable relative to the housing, the input shaft supporting chuck jaws, and a chuck actuating shaft mounted for rotation on the input shaft; and power take off means for adjusting into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft. 17. The power driver as set forth in claim 16, wherein the housing rotatably supports the tool chuck; and wherein the power take off means in the CHUCK MODE rotationally fixes the input shaft to the housing. 18. The power driver as set forth in claim 16, wherein the power take off means is for adjusting into a MANUAL OVERRIDE MODE to manually rotate the input shaft relative to the chuck actuating shaft. 19. The power driver as set forth in claim 16, wherein the chuck jaws are threadless chuck jaws. 20. A power driver comprising: a tool chuck having an input shaft with a rotation axis, and a chuck actuating shaft mounted for rotation on the input shaft; a transmission shaft with a rotation axis that is parallel to and spaced apart from the rotation axis of the input shaft; and a power take off mechanism connected to the tool chuck and being adjustable into a DRILL DRIVE MODE to rotationally drive the input shaft and the chuck actuating shaft together as a unit, and a CHUCK MODE to use the transmission shaft to rotationally drive the chuck actuating shaft relative to the input shaft.
