Patent number: 11565356Abstract: A method for producing a replaceable cutting head is described. The replaceable cutting head is manufactured by extruding a blank. During extrusion of the blank, a number of helical coolant channels and a number of helical flutes are simultaneously formed. After extrusion, the flutes have a first angle of twist (D1), and the coolant channels have a second angle of twist (D2). After extrusion, the blank is sintered and then reworked to selectively adjust the first angle of twist (D1) and the pitch of the flutes. The method produces an endless blank that is capable of being parted off to a desired length without any sacrificial allowance, which provides significant material and cost savings as compared to conventional methods.Type: GrantFiled: July 13, 2018Date of Patent: January 31, 2023Assignee: KENNAMETAL INC.Inventor: Tim Guter

Patent number: 10213845Abstract: A rotary tool designed as a modular drill, extending in an axial direction along an axis of rotation. It comprises two coupling parts: a carrier; and a cutting head that is attached to the carrier so as to be exchangeable. The carrier includes pin receiving means, into which a coupling pin of the cutting head is introduced in a clamping manner and so as to be reversibly exchangeable. The pin receiving means and the coupling pin have torque sections and clamping sections that correspond to one another and are oriented parallel to the axis of rotation. In addition, to prevent axial pull-out, stop surfaces are provided on the pin receiving means and on the coupling pin, the stop surfaces being effective in an axial direction and corresponding to one another. These stop surfaces preferably extend horizontally and therefore perpendicular to the axis of rotation.Type: GrantFiled: March 24, 2015Date of Patent: February 26, 2019Assignee: KENNAMETAL INC.Inventors: Jürgen Schwägerl, Berthold Heinrich Zeug, Horst Manfred Jäger, Herbert Rudolf Kauper, Julia Tempelmeier, Tim Guter
