Abstract
A rotary tool including a tool body defining an axis extending between a rear end and an opposite working end, a motor configured to receive power from a power source, a drive shaft coupled to the motor with the motor, a chuck coupled to the drive shaft, and an axial adjustment mechanism. The axial adjustment mechanism includes an adjustment shaft having an axial end defining a floor of the chuck, where the floor limits an insertion depth within the chuck, and where the adjustment shaft is movable in a direction parallel to the axis between a first position defining a first insertion depth and a second position defining a second insertion depth.
Claims17
A rotary tool comprising:
- a tool body defining an axis extending between a rear end and an opposite working end;
- a motor configured to receive power from a power source;
- a drive shaft coupled to the motor for co-rotation therewith upon operation of the motor;
- a chuck coupled to the drive shaft for co-rotation therewith, the chuck being positioned adjacent the working end and being configured to engage a tool accessory;
- and
- an axial adjustment mechanism including
- an adjustment shaft having a plurality of detent recesses along its length, and an axial end defining a floor of the chuck, the floor limiting an insertion depth of the tool accessory when the tool accessory is received within the chuck, and
- a ball detent configured to selectively engage each of the plurality of detent recesses,
- wherein the adjustment shaft is movable in a direction parallel to the axis between a first position defining a first insertion depth and a second position defining a second insertion depth.
A rotary tool assembly comprising:
- a base including a power receptacle operable to receive a power source;
- a power cord electrically coupled to the power receptacle and configured to transfer power from the power source;
- and
- a rotary tool electrically coupled to the power cord, the rotary tool including
- a body defining an axis extending between a rear end and an opposite working end,
- a motor configured to receive power from the power source via the power cord,
- a drive shaft coupled to the motor for co-rotation therewith upon operation of the motor,
- a chuck coupled to the drive shaft for co-rotation therewith, the chuck being positioned adjacent the working end and being configured to engage a tool accessory,
- an axial adjustment mechanism including an adjustment shaft having a plurality of detent recesses along its length and an axial end defining a floor of the chuck, the floor limiting an insertion depth of the tool accessory when the tool accessory is received within the chuck, and
- and a ball detent is configured to selectively engage each of the plurality of detent recesses,
- wherein the adjustment shaft is movable between a first position defining a first insertion depth and a second position defining a second insertion depth.
