Patent number: 11577323Abstract: A tool head has a longitudinal axis, forward and rearward ends, and top, bottom and peripheral surfaces. The peripheral surface has first and second side walls provided with respective first and second serrated portions, each of the first and second side walls being divided into spaced apart top and bottom side wall portions. The peripheral surface also has a stopper wall which faces in the rearward direction, extends transversely to the second side wall and is provided with a stopper serrated portion. A rear wall formed at the rearward end and connects the first and second side walls. The tool head also includes an insert retaining portion proximate the forward end, and a coupling portion which extends in the direction of the rearward end and includes vertically spaced apart top and bottom coupling arms separated by a coupling recess opening out to the rear wall.Type: GrantFiled: June 8, 2021Date of Patent: February 14, 2023Assignee: Iscar, Ltd.Inventors: Rafi Rabouh, Roman Fortfel, Grigori Neiman, Daniel Hen

Patent number: 10730115Abstract: A cutting tool fastener having a rotation axis and configured to secure together, and establish a fluid path between, two cutting tool members, while also accommodating angular and pivotal displacement between the two. The fastener comprising a head with at least one head opening for emitting fluid, and a body which extends from the head and has a body opening for receiving fluid to be emitted via the head opening. The head has a spherical head abutment surface with a bottom spherical seal surface zone. At least a portion of the spherical head abutment surface faces the body, and the head opening opens out to the spherical head abutment surface. The bottom spherical seal surface zone is axially located between the body and the head opening.Type: GrantFiled: November 19, 2018Date of Patent: August 4, 2020Assignee: Iscar, Ltd.Inventors: Leonid Amstibovitsky, Grigori Neiman

Patent number: 8696253Abstract: A cutting tool (10, 36, 43) includes a coolant channel (22) having a coolant outlet (24) formed with an elongated shape, wherein a medial line (A) extending longitudinally along the coolant outlet (24) comprises a bend (60). The coolant outlet may be formed on a housing which is mounted on a tool body, or may be formed directly on the tool body itself.Type: GrantFiled: May 31, 2011Date of Patent: April 15, 2014Assignee: Iscar, Ltd.Inventors: Leonid Amstibovitsky, Grigori Neiman

Patent number: 8568065Abstract: A cutting tool has an insert holder for retaining a tangential cutting insert in an insert pocket. The insert pocket has a bottom surface, a rear surface and a base surface. The base surface has three abutment protuberances that extend from the base surface. Each base abutment protuberance has a respective base abutment surface. The three base abutment surfaces abut the cutting insert at three points to provide stable seating of the cutting insert in the insert pocket.Type: GrantFiled: September 22, 2011Date of Patent: October 29, 2013Assignee: Iscar, Ltd.Inventors: Grigori Neiman, Yuri Davidov

Patent number: 8465232Abstract: A cutting tool includes a coolant conveying member, to provide coolant fluid to a cutting area during a cutting operation. The coolant conveying member includes a member body having a fluid passage formed therein, and a nozzle to convey and to jet out the coolant fluid therethrough. The nozzle is shiftable relative to the member body, between a first, extended position and a second, retracted position. In the extended position, for example, assumed during the cutting operation—the nozzle extends out and forwardly from the member body, stabilized by the continuous flow of coolant fluid therethrough, forcing the nozzle forwardly. In the retracted position, for example, assumed when the when the coolant fluid does not flow through the coolant conveying member, or flows at a very low rate, the nozzle may be at least partially accommodated in the fluid passage, to allow, for example, indexing or replacing of the cutting insert.Type: GrantFiled: January 15, 2010Date of Patent: June 18, 2013Assignee: Iscar, Ltd.Inventors: Leonid Amstibovitsky, Grigori Neiman
