Abstract: A power tool includes a head interface coupled to a forward end of an output shaft and a tool head element for engagement on the head interface. The tool head element has a housing including an input shaft configured to removably couple with the output shaft and a collar comprising locking elements. In embodiments, locking elements are biased inwardly towards the input shaft by biasing elements (springs). In others, magnet(s) and/or ball locking elements may be utilized. Upon attachment of the tool head element to the head interface, the tool head element may held by the provided elements (e.g., locking elements, biasing springs, magnets, balls) onto the head interface and a drive connection between the output shaft and input shaft is established. Thus, when a motor and transmission assembly of the tool is operated, the input shaft rotates with the output shaft about the axis and thus drives the tool head element.

Abstract: A power tool includes a head interface coupled to a forward end of an output shaft and a tool head element for engagement on the head interface. The tool head element has a housing including an input shaft configured to removably couple with the output shaft and a collar comprising locking elements. Each locking element is biased inwardly towards the input shaft by biasing elements. Upon attachment of the tool head element to the head interface, the locking elements are aligned into a circumferential groove of the head interface and held by the biasing elements therein to engage the tool head element onto the head interface and establish a drive connection between the output shaft and input shaft. Thus, when a motor and transmission assembly of the tool is operated, the input shaft rotates with the output shaft about the axis and thus drives the tool head element.

Abstract: A power tool accessory includes a housing having a rear end portion and front end portion; an input shaft at least partially received in the rear end portion, extending along an axis, and configured to be coupled to a tool holder of a rotary power tool; a threaded shaft received in the housing and rotationally driven by the input shaft; a blade holder configured to move along the axis upon rotation of the threaded shaft; and a cutting blade configured to be retained by the blade holder. A workpiece holder is coupled to the front end portion of the housing and is configured to hold an elongated member. Upon rotation of the input shaft, the threaded shaft rotates, causing the blade holder to move axially toward the front end portion of the housing, causing the blade to move at least partially into the workpiece holder to cut the elongated workpiece.
