Abstract
A cutting tool includes first and second parts interconnected by respective connecting surfaces. Each connecting surface includes a serrated connecting surface having alternating ridges and grooves. Each groove is formed by two flanks of respective adjacent ridges and has a cross-sectional shape which becomes narrower toward a bottom of the groove. At least one of the groove flanks of the first part includes a plurality of contact surfaces spaced apart by a clearance surface, wherein a ridge of the second part is in contact with the contact surfaces and is out of contact with the clearance surface. The contact surfaces could be spaced apart along a length of the groove flank and/or along a height of the groove flank.
