摘要： A cutter tooth assembly includes a cutter tooth having a shank portion and a cutting portion, and a cutter tooth holder having a pocket for receiving at least a portion of the shank portion of the cutter tooth. The shank portion of the cutter tooth has a plurality of tapered surfaces formed at a first angle with respect to a vertical axis of the cutter tooth, and the pocket of the cutter tooth holder has a plurality of tapered surfaces formed at a second angle with respect to a vertical axis of the cutter tooth holder that cooperate with the plurality of tapered surfaces of the shank portion of the cutter tooth to minimize tolerances between the shank portion of the cutter tooth and the pocket of the cutter tooth holder during wear of the cutter tooth assembly.

摘要： 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.

摘要： The invention relates to a tool for installing a bit on and/or deinstalling a bit from a bit holder system of a milling machine, in particular a road milling machine, having at least one initiator with which installation and/or deinstallation of a bit is initiated. Provision is made that the tool comprises a detection device having at least one counting device; and that the detection device is designed to detect a number of bits deinstalled using the tool and/or a number of bits installed using the tool. The invention also relates to a corresponding bit holder system and to a method for monitoring wear. With the tool and the bit holder system, additional information regarding bit changes that have been carried out is made available to a user.

摘要： A round-shank pick having a pick head and a pick shank that includes a supporting element pierced along its longitudinal center axis by a mounting hole with an inside diameter for receiving the pick shank. A collar height, measured in the direction of the longitudinal center axis between an end, facing away from the seat surface, of the centering extension and the seat surface or between the end of the centering extension and an inner termination of a recess that is integrally formed in the supporting element in an indented manner with respect to the seat surface, is configured such that the ratio between the inside diameter of the mounting hole in the supporting element and the collar height is less than 8, and/or that the collar height is greater than an axial clearance of the pick mounted in a pick holder.
