Abstract
A center cutting indexable insert end mill which can be used for axial plunging in solid material or side cutting. The center cutting insert having corner radii is positioned with the axial center line of the tool shank intersecting the inner corner radius. A single square insert with side clearance angle having the cutting face located in a radial plane provides alternate active cutting edges for axial and/or radial feed; alternatively a second diametrically oppositely located identical insert located radially outward of the center cutting insert performs side and outermost axial cutting functions.
