摘要： A rotary cutting tool that is composed of a tool shank with at least one chucking groove or chip flute and one exchangeable cutting insert. At the tip of the shank a recess for accommodating the cutting insert is provided. The tool shank, on its circumference, has a limb with a bearing surface that is inclined relative to the tool axis and that corresponds to a likewise inclined bearing surface on a wing of the cutting insert. The inclination of the bearing surfaces produces an axial force that retains the cutting insert on the tool shank.

摘要： An collet and lock nut assembly includes a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the shank. The collet has a nose portion and a body portion separated by an annular groove. The lock nut has a plurality of retention tabs and a corresponding number of clear portions. The collet and lock nut assembly can be easily assembled by inserting at least one retention tab within the groove of the collet, and then applying pressure to the collet such that the remaining retention tabs of the lock nut are received within the groove of the collet to place the assembly in a locked position. The collet and cutting tool shank can be drawn from the tool holder by applying rotational torque to the lock nut. The collet is easily removed from the lock nut by applying pressure in any circumferential, lateral direction against the collet.

摘要： An assembly generally comprises a collet for receiving a cutting tool shank and a lock nut for creating a gripping force between the collet and the cutting tool shank. The collet has a nose and the lock nut has a front face that is substantially flush with the nose. The lock nut further has a fastening element that mates with a fastening element of a coolant sealing ring for attaching the coolant sealing ring to the lock nut so that the coolant sealing ring may be detached from the lock nut.
