Abstract
Collet chucks are described herein having design and architecture for minimizing and/or mitigating collet misalignment during rotary tool coupling operations. For example, a collet chuck comprises a housing for connection and rotation with a spindle about an axis of rotation, wherein the housing defines a socket for receiving a collet. The collet comprises a nose end engaging the socket and a second tapered end engaging a locknut assembly.
