A milling machine, in particular a hand-held milling machine, for milling bevels and fillets, having a housing in which a drive device and a spindle are mounted, wherein the spindle is configured to receive at least one cutting device and is connected to the drive device via at least one transmission. Additionally, a rebound damper for protecting the transmission is provided on the spindle.

The present invention relates to a method for faceting at least one workpiece edge (6) on at least one workpiece side (3, 4, 5) of at least one workpiece (2) by means of a device (1), comprising at least one workpiece holder (10), at least one measuring apparatus (30) and at least one faceting tool (40), which is movable relative to the workpiece holder (10), having the following method steps: —providing the at least one workpiece (2), —positioning and securing the at least one workpiece (2) on the workpiece holder (10), —determining the position of the at least one workpiece edge (6) of the at least one workpiece (2) relative to the workpiece holder (10), and—moving along the at least one workpiece edge (6) with the at least one faceting tool (40) and processing the facet.

A router bit (100), including: a shank (104) that defines a longitudinal axis (106); a cutter (110); a body (112) that secures the cutter to the shank; and a recess (120) in the body that is disposed between axial ends (122, 124) of the cutter, and that includes an indexing feature (126).

A tool for performing work on a workpiece, such as a pipe, includes a mandrel assembly configured to secure to an interior portion of the pipe. The mandrel assembly includes an arm assembly configured to retain a cutting apparatus so as to be positioned at an outside portion of the pipe and to allow the cutting apparatus to revolve around the circumference of the pipe to perform work on the pipe. The mandrel assembly includes a hub and a plurality of jaws that allow it to secure to the interior of the pipe while the arm assembly props the cutting apparatus in a position to facilitate performing work on the pipe around the entire circumference of a section of the pipe. The engagement between the mandrel assembly and the pipe supports the weight of the tool, providing ease of use and improved control for pipe cutting operations.

A bearingless groove router bit includes at least one cutting element affixed to a head of the router bit and has a first end spaced from an end of connected shank connected to the head and a second end adjacent to the second end of the head. The cutting element includes a cutting edge extending along the cutting element between the first end to the second end of the cutting element. The cutting edge may include a radial side edge that projects radially inwardly relative to a central axis of the router bit and a straight side edge that extends from an end of the radial side edge outwardly relative to the central axis to minimize tear out during cutting of a groove in a work piece.

A portable rail weld milling machine apparatus comprises a support structure comprising a milling tool, wherein the milling tool comprises a milling head for milling a railroad rail by moving the milling tool in a first direction longitudinal to parallel railroad rails, in a second direction lateral to the parallel railroad rails, and a third direction vertically.

According to an aspect of the present disclosure, a low profile travelling pipe cutter is provided which is adapted to perform at least one of cutting and beveling a hollow vessel while traveling around the vessel using a cutting tool mounted thereon. The pipe cutter includes inner and outer carriages, a capstan assembly attached to the outer carriage to which a feed cable is attached, and rollers attached to the outer carriage to which a tension cable is attached. The force adjustment assembly changes the vertical position of the outer carriage relative to the inner carriage to compensate for the pipe cutter going inwardly and outwardly as it travels around a hollow vessel in order to maintain constant pressure caused by the lever tension interface. A guard assembly is provided for covering and uncovering the cutting tool during cutting.
