Publication number: 20250262674Abstract: A modular boring head includes a tubular main body having a slot, a movable rod engaging the tubular main body, a leadscrew disposed within the tubular main body and a compact click mechanism mounted to the leadscrew. The click mechanism includes a spur gear and an elastic latch element that acts as a bidirectional ratchet disposed radially outward with respect to the spur gear. During operation, rotation of the leadscrew causes the elastic latch element to move in an axial direction, D, within the slot and also causes the bidirectional ratchet or elastic latch element to cooperatively engage the spur gear in such a manner so as to produce an audible and tactile click, each click being indicative of a distance that the movable rod is displaced in the axial direction, D, with respect to the tubular main body.Type: ApplicationFiled: February 21, 2024Publication date: August 21, 2025Applicant: Kennametal Inc.Inventors: Marcelo Euripedes da Silva, Ruy Frota de Souza Filho, Patrick Kuhlemann, Eduard Ach, Ingo Grillenberger

Publication number: 20240375185Abstract: A cutting tool includes a base body and a cutting head at least partially disposed within a modular pocket of the base body. The modular pocket is formed by at least one wall section removably attached to the base body. In one variation, a non-removable portion of the base body also forms part of the modular pocket. In another variation, the modular pocket is formed by two removable wall sections on opposite sides of the modular pocket. In yet another variation, the removable wall sections include a clamping portion to exert a downward force on the cutting head to enable mounting the cutting head in the modular pocket using an interference fit.Type: ApplicationFiled: July 24, 2024Publication date: November 14, 2024Applicant: Kennametal Inc.Inventors: Patrick Kuhlemann, Michael Schuffenhauer, Marcelo Euripedes da Silva, Ruy Frota de Souza Filho
