A cutting insert adaptor for an insert pocket can include one or more pairs of opposing insert abutment surfaces and pocket abutment surfaces which converge at an acute angle. The one or more insert abutment surfaces are all rotated in the same direction, relative to their paired pocket abutment surface which in turn rotates a cutting insert abutting the cutting insert adaptor relative to an orientation the cutting insert would have if it only abutted the insert pocket instead of the cutting insert adaptor.

A purpose is to provide a cartridge that can adjust position even if a body does not have an adjusting mechanism. A cartridge 10 is provided on a body B of a milling tool. The cartridge 10 is connected to an upper surface 10a, a lower surface 10b, and a first side surface 10c, and a slit 10h that divides the cartridge 10 into a main body part 10j, a thin material portion 10k, and a connecting part 10m that connects the main body part and the thin material portion is formed in the cartridge. Furthermore, a screw hole 10n with second female threads is formed in order for a second male screw that passes through the slit 10h to screw into. Furthermore, wherein the second male screw travels forward, the relative position of the main body part 10j changes with regard to the thin material portion 10k.

The invention relates to a cutting tool having a main body (4) extending along a longitudinal central axis (9) and a cutting insert (1), which is held on the main body (4) in an axially and/or radially positionally-adjustable manner and can be tensioned by means of a clamping claw (3). According to the invention, the cutting insert (1) is held by a clamping holder (2), which is held in a positionally-adjustable manner on the main body (4), and which can be tensioned on the main body (4) by means of the clamping claw (3) pressing against the cutting insert (1).

An insert may include a base member and a resin layer located on the base member. The base member may include a first surface, a second surface, and a cutting edge. The first surface includes a rake surface region. The second surface may be adjacent to the first surface and includes a flank surface region. The cutting edge may be located in at least a part of a ridge line at which the first surface intersects with the second surface. The resin layer may not be located on the second surface but may be located on the first surface.

A rotary cutting tool is provided which, although it has a simple configuration, allows the arrangement of each cutting edge to be easily adjusted. A first cartridge mounting seat has an upper wall surface opposing an outer side surface of a cartridge and further has a first recessed part into which a protrusion is inserted and which comes into contact, at a bottom thereof, with a leading end of the protrusion. A second cartridge mounting seat has an upper wall surface opposing an outer side surface of a cartridge and further has a second recessed part into which a protrusion is inserted and which comes into contact, at a bottom thereof, with a leading end of the protrusion. A depth of the second recessed part is greater than a depth of the first recessed part. An amount of protrusion P of the protrusion is equal to or greater than the depth of the second recessed part.

A milling tool having multiple cutting disks is disclosed. Each cutting disk is anchored into a flute on the milling tool with clamping screws. During use, the cutting disks naturally become dull. In a preferred embodiment, a single clamping screw is used to hold the cutting disk in place. The clamping screw is loosened and the cutting disk is rotated such that a new and sharp portion of the cutting disk is exposed for use. In an alternative embodiment, multiple clamping screws are used to secure the cutting disk into the flute. In the event a cutting disk becomes stuck in a flute, a clamping screw in a threaded bore coaxially aligned with the locating bore is used to push the cutting disk and eject it out of the flute. This design allows for many positions on the cutting disk to be used before the disk needs to be replaced, sharpened, or refurbished.
