Patent number: 7147414Abstract: A cutting tool insert having a specialized spur point geometry at the center of the insert. The insert comprises a spur point cutting portion and a blade cutting portion wherein the spur point provides stability by providing a spot and allowing a flexible workpiece to partially spring back when the spur breaks through. The spur point insert facilitates the cutting of relatively thinner workpieces and workpieces requiring the tool to have a longer reach to the hole, while minimizing the burr resulting from the drilling operation.Type: GrantFiled: June 19, 2003Date of Patent: December 12, 2006Assignee: Allied Machine & Engineering Corp.Inventors: Wendell E.
