Publication number: 20200360997Abstract: A method for manufacturing a tool head includes forming a first and a second part from a powder composition. The first and the second parts include corresponding joining surfaces, and the parts have outer surface portions configured to form portions of a peripheral envelope surface of the tool head. The method further includes forming corresponding grooves in the corresponding joining surfaces, assembling the parts into a shape of a tool head by bringing the joining surfaces into contact to form an interface, so that each pair of corresponding grooves forms a channel extending in the interface, the channel having an inlet opening in a rear end of the tool head and an outlet opening in a front end or in the peripheral envelope surface of the tool head, and joining the assembled parts in a sintering operation to form the tool head.Type: ApplicationFiled: November 22, 2018Publication date: November 19, 2020Inventor: Stefan FREJD

Patent number: 8430609Abstract: A tool for rotary cutting machining includes a tool body and a replaceable cutting head detachably attachable to the tool body. The cutting head has a coupling portion which is receivable in a space between two axially projecting coupling legs of the tool body. Cylindrical internal gripping surfaces are arranged in said space and designed for engagement with corresponding cylindrical external gripping surfaces of the cutting head. The gripping surfaces of the cutting head and the gripping surfaces of the tool body are dimensioned so as to prevent, by engagement with each other, the cutting head from being displaced in axial direction away from the tool body when the cutting head is attached to the tool body. A tool body and a cutting head included in such a tool are also disclosed.Type: GrantFiled: April 14, 2009Date of Patent: April 30, 2013Assignee: Seco Tools ABInventor: Stefan Frejd

Patent number: 6821061Abstract: A drill for chip forming metalworking includes three cutting edge structures spaced circumferentially apart. Each cutting edge structure includes a radially outer cutting edge and a radially inner cutting edge. Each radially inner cutting edge is inclined in a radially inner and axially rearward direction from a radially inner end of its associated radially outer cutting edge. That radially inner end constitutes a breakpoint between each radially outer cutting edge and its respective radially inner cutting edge. The breakpoints lie in a common circle whose center coincides with the center axis of the drill.Type: GrantFiled: October 23, 2002Date of Patent: November 23, 2004Assignee: Seco Tools ABInventor: Stefan Frejd
