An apparatus (100) for machining a tubular or round-bar type piece, wherein the apparatus comprises a frame element (102), a machining unit (104), as well as a threaded shaft (110), which is fitted to the frame element in a rotatable and axially immobile fashion and has a first section 110a) provided with a right-handed thread and a second section (110b) with a left-handed thread. The first section is provided with at least one first support element (106a) and the second section is provided with at least one second support element (106b), the mutual distance between the support elements being adjustable in response to rotating the threaded shaft, such that the support elements, for example wheels, are adapted to touch a workpiece and to support and guide the apparatus (100) in the process of machining the piece. At least one of the support elements, such as wheels (106a, 106b), is adapted to be capable of rotating relative to its axis in response to moving the apparatus along the surface of a workpiece.

A router includes a housing and a motor assembly disposed within the housing. The motor assembly includes a driven shaft having a cavity on a first end of the driven shaft. The router includes a collet that is configured to mate into the cavity of the driven shaft with the collet being configured to grip a shank of a router bit. The router includes a gear mechanism that is configured to couple and decouple from a second end of the driven shaft such that a rotation of the gear mechanism when the gear mechanism is coupled to the second end of the driven shaft causes at least one of tightening and loosening of the collet.

A dust and debris collection system for use with woodworking routers, including a baffle, a dust collection hood, and a brush. The baffle includes a top surface, where the top surface is configured to deflect cooling air generated by a woodworking router out and away from the woodworking router in order to allow the woodworking router adequate cooling and efficient dust collection. The dust collection hood is located adjacent to the baffle and includes a sloped wall that is aerodynamically shaped to remove dust and debris and includes a central bit hole configured to accept a bit. The brush has a series of bristles extending from the dust collection hood. The brush and its bristles contain dust and debris.

Embodiments of the present disclosure include portable milling tools and methods for milling components. In an embodiment, a portable milling tool can be provided for a component including a plurality of dovetail slots therein, each of the plurality of dovetail slots being oriented substantially axially relative to a rotation axis of the component. The portable milling tool can include: a mounting plate configured to engage the component; a tool-aligning member slidably coupled to the mounting plate and extending along a chordal axis relative to the rotation axis of the component; and a milling head extending axially from the tool-aligning member to a selected one of the plurality of dovetail slots, such that sliding movement of the tool-aligning member relative to the mounting plate moves the milling head along the chordal axis to contact a selected one of the plurality of dovetail slots.
