A rotatable tool for producing a circular groove through metal cutting in a metal work piece and a method of forming the circular groove with the rotatable tool is disclosed. The rotatable tool includes a front end and a second end. The front end includes a first radially outer cutting edge and a second radially inner cutting edge, where the first radially outer cutting edge is located at a larger radial distance from the tool center axis than any other cutting edge of the rotatable tool, and where the second radially inner cutting edge is located at a smaller radial distance from the tool center axis than any other cutting edge of the rotatable tool.

The invention relates to a method for producing a roughing tool (1), particularly a circular milling tool, comprising the following steps: fitting a lateral surface of a tool base body (10) that can be rotatably driven about an axis of rotation (2) with a number of cutting element blanks (20) that are staggered in the axial and/or peripheral direction, such that a free edge of each cutting element blank (20) protrudes out of the lateral surface in the mounted state; inserting a microtoothing comprising a plurality of axially spaced cutting teeth (21) into the respective free edges of the cutting element blanks (20) by a material removal method, preferably by thermal machining, particularly preferably by eroding, in the premounted state on the tool base body (10). The invention further relates to a roughing tool produced by means of such a method.

Provided is a milling cutter including: a tool body to rotate about an axis; and cutting edges at an outer peripheral part of a front end of the tool body, wherein the cutting edges include a flat face machining cutting edge extending along a virtual plane perpendicular to the axis, and a recessed groove machining cutting edge projecting further toward a front end side in the axial direction than the flat face machining cutting edge, and the recessed groove machining cutting edge has a first inclined portion extending toward the front end side in the axial direction toward an outside in a radial direction, a second inclined portion arranged outside the first inclined portion in the radial direction and extending toward a base end side in the axial direction toward the outside in the radial direction, and a tip portion connecting the first and second inclined portions.

The present invention provides an apparatus and a method for manufacturing a wheel hub to reduce lateral run-out. Specifically, the present invention provides an apparatus and a method for machining the inner and outer surfaces of the wheel hub after the wheel bolts and bearing have been attached to the wheel hub. A grind wheel is used to finish an inner flange portion and outer flange portion of the wheel hub.
