A collet for a tool, the collet comprising:
- an outer nut including a grip and defining a collet bore configured to receive a chuck and having a collet engagement surface engageable with the chuck to selectively secure a tool accessory;
- and
- a spring including an extension portion engageable with an external part of an output shaft of the tool or an internal part of the outer nut to provide feedback to a user regarding securement of the collet.
A tool comprising:
- an output shaft coupled to the tool and including a threaded portion and a groove disposed in the output shaft;
- an inner chuck;
- and
- a collet selectively engageable with the output shaft, the collet including:
- an outer nut defining a collet bore configured to receive the inner chuck and having a collet engagement surface engageable with an end of the inner chuck to selectively secure a tool accessory to the output shaft;
- and
- a spring coupled to the outer nut and including an extension portion configured to engage the groove to provide feedback to a user regarding securement of the tool accessory on the output shaft.
A collet configured to couple to an output shaft of a tool, the collet comprising:
- an outer nut configured to engage the output shaft and defining apertures arranged annularly on the outer nut, the outer nut configured to selectively secure a tool accessory to the output shaft;
- and
- a spring coupled to the outer nut and including extension portions, a first extension portion of the extension portions extending through a first aperture of the apertures and a second extension portion of the extension portions extending through a second aperture of the apertures to secure the spring to the outer nut for co-rotation, wherein each of the extension portions is configured to engage an external part of the output shaft.
