Abstract: The tool includes a mandrel on which is seated and axially held an exchangeable milling cutter, coupled to the mandrel by a clutch drive ring for shell end mill arbors, for transmitting the torque during the milling procedure. In addition, a stop element is mounted on the mandrel, held against an axial displacement, but permitting relative rotation of the mandrel for operating the cutter, whereby particularly a thrust bearing is used between the mandrel and the stop element. The stop element is adjustable and limits the longitudinal movement of the cutter. To prevent any damage to the chamfer-area around the housing-bore hole by the cutter, the stop has to be adjusted accurate to the gauge, in reference to the cutting edge geometry of the cutter teeth, so that just a thin blade of material of the outer ring lip remains. The whole device is centered with the mandrel in the bore of the bearing or bushing which is to be removed after cutting one ring lip.

Abstract: A portable tool is disclosed in which hydraulically a two-arm lever is operated to move a staking head towards the grooved outer race of a bearing, which is supported by a staking foot towards each other. Staking head and staking foot are mounted in the legs of a U-shaped tool attachment, being keyed into and releasably bolted to the holder for the hydraulic drive.
