Patent number: 12103096Abstract: A machining tool (1) includes a tooth (3) having a tooth tip (4) being covered with cutting particles (5) to form a plurality of geometrically undefined cutting portions. The tooth tip (4) is designed to be asymmetrical. The machining tool (1) thus is a 2-in-1 machining tool including differently designed sides of the tooth tips (4) which are suitable for efficiently machining different materials.Type: GrantFiled: December 10, 2021Date of Patent: October 1, 2024Assignee: WIKUS-Sägenfabrik Wilhelm H. Kullmann GmbH & Co. KGInventor: Jörg H. Kullmann

Patent number: 10363620Abstract: A saw band (1) includes a chamfered tooth (10) including two effective cutting edge portions (7) being arranged in the region of the chamfer (15) between which an ineffective cutting edge portion (8) of the first tooth (10, 11) is formed. In this way, five cutting channel portions (18) are formed by only two geometrically differently designed teeth (10).Type: GrantFiled: March 27, 2018Date of Patent: July 30, 2019Assignee: WIKUS-SAEGENFABRIK WILHELM H. KULLMANN GMBH & CO. KGInventors: Joerg H. Kullmann, Dirk Heimel

Patent number: 9597742Abstract: A saw blade (1) includes a tooth supporting body (2) and a plurality of teeth (3) being arranged at the tooth supporting body (2). Each of the plurality of teeth (3) includes a tooth tip (8) including a cutting portion (9). The cutting portion (9) and at least another part of the tooth tip (8) of the teeth (3) are made of a steel alloy that has been produced by powder metallurgy and full annealing.Type: GrantFiled: May 7, 2013Date of Patent: March 21, 2017Assignee: WIKUS-SAEGENFABRIK WILHELM H. KULLMANN GMBH & CO. KGInventors: Joerg H. Kullmann, Gert Kellezi, Devrim Caliskanoglu

Patent number: 9162299Abstract: A saw blade (1) serves for sawing hollow profiles and form profiles. The saw blade (1) is especially designed as saw band, and it includes a base body (2) and a plurality of teeth (10). The teeth (10) are formed by protrusions (3) and inserts (4). The teeth (10) are arranged in a group being repeated along the saw blade (1). The group includes at least three unset chamfered teeth (10). The group includes a first tooth (C1) having two chamfers (FC11, FC12) being symmetric to the longitudinal center plane (9) of the saw blade (1), a second tooth (C2) having two chamfers (FC21, FC22) being non-symmetric to the longitudinal center plane (9) and a third tooth (C3) having two chamfers (FC31, FC32) being non-symmetric to the longitudinal center plane (9).Type: GrantFiled: May 4, 2012Date of Patent: October 20, 2015Assignee: WIKUS-SAEGENFABRIK WILHELM H. KULLMANN GMBH & CO. KGInventors: Jörg H. Kullmann, Patrick Gleim, Martin Hentschel

Patent number: 8695470Abstract: A saw blade (1) includes a base body (2) and a plurality of teeth (10) being connected to the base body (2), the teeth (10) including a cutting portion (6) and a chip producing surface (7). At least a part of the teeth (10) are arranged in a group of teeth being repeatedly arranged along the base body (2). The group of teeth (10) includes at least three unset teeth (10) having different widths. The broadest tooth (10) in the group of teeth (10) does not include a chip deforming element being located next to the chip forming surface (7) in a direction facing away from the cutting portion (6). At least one other tooth (10) in the group of teeth (10) includes a chip deforming element (8) being located next to the chip forming surface (7) in a direction facing away from the cutting portion (6).Type: GrantFiled: July 21, 2010Date of Patent: April 15, 2014Assignee: Wikus-Saegenfabrik Wilhelm H. Kullmann GmbH & Co. KGInventors: Joerg H Kullmann, Frank Carrier
