Abstract: 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.

Abstract: 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.

Abstract: 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).

Abstract: A coupler for use in connecting together in a driving relationship a first member and a second member in a rotatable cutter assembly includes an elongate body having an axial forward end and an axial rearward end, and the elongate body containing a longitudinal bore. The elongate body further includes a collar mediate of the axial forward end and the axial rearward end, a forward body portion axially forward of the collar wherein the forward body portion is configured to drivingly engage the first member and a rearward body portion rearward of the collar wherein the rearward body portion is configured to drivingly engage the second member. The rearward body portion of the elongate body includes an elastomeric layer formed thereon.

Abstract: A rotatable cutting tool includes a cutting tool body with a head portion. A bolster is at least partially received in the head portion and includes a socket, a collar portion and a shank portion. The socket is formed with a conical side wall and a radius blend. A hard tip or cutting insert is at least partially received in the socket and includes a conical head portion, a collar portion and an axially rearward frustoconical portion that generally conforms to the geometry of the socket of the bolster. The shank portion of the bolster provides a narrow bottom style geometry and the axially rearward frustoconical portion of the cutting insert provides a tapered geometry that together increases the strength of a braze joint between the bolster and the base portion, thereby reducing forces and stresses transmitted to the cutting tool during a machining operation.
