  • Tool with changeable working tip
    Patent number: 5597275
    Abstract: A tool with changeable working tips has a tool shaft with an attachment end adapted to receive the attachment end of a working tip in freely removable engagement therewith. A sleeve is moved over the engagement of the shaft and working tip to securely hold the shaft and working tip together in engaged position so that any rotation or other movement of the shaft is transferred to the working tip. The sleeve is removable from around the engagement ends of the shaft and working tip, such as by removal from the tool or retraction into the tool, to allow the working tip to be removed from engagement with the shaft and a different working tip to be engaged with the shaft. The sleeve is replaced over the engagement of the engagement ends to hold the different working tip in place.
