Abstract: A method of clamping a first cutting insert or an adaptor to a holder. Either the holder includes two insert pockets configured for machining in two different orthogonal directions or the holder includes a single adaptor pocket configured for holding the adaptor in two different orthogonal directions. The method includes the steps of choosing one of two orthogonal directions for machining and securing either the first cutting insert to an appropriate one of the two pockets or securing the adaptor to the adaptor pocket for machining in the chosen orthogonal direction.

Abstract: A parting-off tool assembly including a blade holder, a parting-blade mounted to, and clamped by, the blade holder, a cutting insert and a coolant conduit mounted to the parting-blade. The cutting insert defining a cutting-edge width CW and an extended-width cutting plane of the same width. The coolant conduit with an outlet opening out to a first extension portion located within the extended-width cutting plane.

Abstract: A parting-off tool assembly including a blade holder, a parting-blade and a clamp. The clamp is secured to the blade-holder via a clamp attachment portion being fastened to the blade holder's holder attachment portion. The clamp also includes a clamp portion which abuts a peripheral edge of the parting-blade to secure the parting-blade to a blade-pocket of the blade holder.

Abstract: A replaceable face-milling head configured for rotating about a central rotation axis AR. The head includes a cutting portion and an integrally formed threaded shank-connector portion, the latter of which being configured for connecting to a shank. A length-diameter ratio LDR, defined as a cutting portion length LC divided by a cutting portion diameter DE, fulfills the condition: LDR?1.00.
