Patent number: 11821313Abstract: A washerless cutting tool assembly includes a cutting tool holder and a rotatable cutting tool at least partially disposed within the cutting tool holder. The cutting tool holder includes an alignment feature in the form of a protrusion at an axial forward end and a groove at an axial rearward end of the head portion of the rotatable cutting tool. The groove is capable of receiving the protrusion of the cutting tool holder to align the central, longitudinal axis of rotatable cutting tool with the central, longitudinal axis of the cutting tool holder. The cutting tool assembly further includes a limited rotated feature in the form of a braking ring disposed within an annular groove and a retainer ring disposed over the braking ring.Type: GrantFiled: January 18, 2023Date of Patent: November 21, 2023Assignee: KENNAMETAL INC.Inventors: Brandon J.

Publication number: 20220288704Abstract: Cutting tools (14) and cutting tool assemblies (10) include a friction ring (79). The friction ring (79) is provided in (disposed/secured within) a retaining groove (32) of a shank (30) of the cutting tool (14). The friction ring (79) can be formed from a resilient material or materials (150). The friction ring (79) can be secured in the retaining groove (32) by a retainer ring (80). The cutting tools (14) can also include a shank (30) having an increased diameter to provide increased strength and allow for a heavier cutting portion (28) of the cutting tool (14). The cutting tools (14) and cutting tool assemblies (10) can also include a washer (100) fitted about the shank (30) and positioned adjacent to a back side (26) of the cutting portion (28) of the cutting tool (14) for stabilizing the cutting tool body (22) in relation to a cutting tool holder (12).Type: ApplicationFiled: March 11, 2021Publication date: September 15, 2022Applicant: Kennametal Inc.Inventor: Brandon J.

Patent number: 10465512Abstract: A cutting tool rotatable about a central longitudinal axis of the cutting tool and configured for impingement upon a substrate includes an elongate cutting tool body having a head and a shank axially rearward of the head. The head includes a cutting member at an axial forward end thereof, a bolster portion axially rearward of the cutting member and a base portion at an axial rearward end of the head. In addition, the bolster portion includes a convex shape section and a generally cylindrical section contiguous with and axially rearward of the convex shape section.Type: GrantFiled: February 28, 2017Date of Patent: November 5, 2019Assignee: KENNAMETAL INC.Inventors: Brandon J. Kenno, Nicholas J. Paros, Chad Swope

Patent number: 10294786Abstract: A rotatable cutting tool (10) includes a cutting tool body (12) having an axial forward end (14) and an axial rearward end (16). A bolster (46) at least partially received in a head portion (22) and includes a convex-shaped head portion (56) with a socket (20), a collar portion (58) and a tapered shank portion (60). The socket (20) is formed with a substantially planar side wall (20a), a bottom wall (20b), and a radius blend (20c). A hard tip or cutting insert (18) is at least partially received in the socket (20) of the bolster (46) and includes a convex-shaped conical head portion (72), a collar portion (74) and an axially-rearward portion (76) that generally conforms to the geometry of the socket (20) of the bolster (46). Between about sixty percent (60%) and about ninety percent (90%) of the cutting insert (18) is received in the socket (20) of the bolster (46), thereby reducing forces and stresses transmitted to the cutting tool (10) during a machining operation.Type: GrantFiled: May 24, 2016Date of Patent: May 21, 2019Assignee: KENNAMETAL INC.Inventors: Luke A. Weber, Brandon J. Kenno, Nicholas J. Paros
