Abstract
A turret hand drill (10) features a turret (22) mounted on the drill for swivel motion about a pivot axis (5) angularly spaced from the tool drive axis (3) of the drill between a pair of opposite index positions. The turret (22) includes a pair of chuck assemblies (26A,26B) arranged symmetrically about and coplanar with the pivot axis (5) of the turret (22) for selective positioning in alignment with the drill tool drive axis (3), with the idle chuck assembly extending downward out of the way. A spring biased clutch mechanism (70) allows for disengagement of a chuck shaft (30) from a drive shaft (20) of the drill by pulling on the chuck (28) to switch between chuck assemblies (26A,26B). A frusto-conical ramp (90 or 94) is engaged by a chuck half (72) of the clutch mechanism as the turret is swiveled to gradually retract the chuck half (72) against the spring bias so that the chuck half is automatically urged into operative engagement with a drive half (74) of the clutch mechanism upon alignment therewith.
