An indexable cutting tool in which cutting ability can be ensured while suppressing the occurrence of chatter vibration. In outer circumferential blades provided on a tool main body, the axial rake angles are all set to the same angle, and so are the radial rake angles. With this configuration, the cutting ability of an indexable cutting tool can be ensured. Furthermore, the disposing intervals, in the circumferential direction of the tool main body, of the plurality of outer circumferential blades that are provided in, at least, a first groove of a plurality of groove are set to unequal values. With this configuration, it is possible to make the intervals at which the outer circumferential blades adjoining in the axis direction contact a workpiece unequal, suppressing resonance of periodic vibration occurring in cutting and, thus, suppressing the occurrence of chatter vibration.

A metal slitter body including a cylindrical body portion and cutting body portions extending outwardly from and integrally formed with the cylindrical body portion. The cutting body portions each include an insert pocket having an insert receiving slot, first and second clamping jaws and a slot end. The slitter body further including a reinforcement portion extending from the cylindrical body in an outward radial direction further than each slot end.

A method for the production of a reamer, such as a burr for milling a patient's acetabular cavity, including a substantially hemispherical, hollow cutting body with a perforated wall. The method includes a step of forming at least one tooth by stamping the wall, during which an area of the thinned portion of the wall, adjacent to a hole, is pressed between a punch and an anvil.

A cutting assembly for milling includes at least two milling cutting tools with shanks that are arranged in a rotatable tool holder at a distance from the central axis of the tool holder, such that an operational region of a cutting portion of each cutting tool is primarily facing outwards, in a radial direction, from the tool holder central axis.

A slotting tool body includes a disc-like cutter portion and a shank portion projecting rearwardly therefrom. The cutter portion includes a resilient clamping portion having a peripherally disposed insert receiving slot. The shank portion includes a peripherally disposed forward shank recess that is axially adjacent the cutter portion. A radially inward portion of the insert receiving slot merges in the rearward direction with the forward shank recess. A cutting insert is releasably and resiliently clamped in the insert receiving slot to form a rotary slot cutting tool. The cutting insert includes two cutting portions that each include a long and short insert lateral extension, the long insert lateral extension being longer than the short insert lateral extension. The longest insert lateral extensions are orated on opposite sides of the cutting insert.

The invention relates to a rotary tool (1; 101; 201) for cutting large inside diameters at the outer circumference (2) of which at least one cutting edge (4) is arranged, comprising a support structure (10; 110; 210) which indirectly or directly supports the at least one cutting edge (4), and comprising a chucking portion (24) for coupling to a tool holder, wherein the support structure (10; 110; 210) widens in an umbrella-type manner starting from a coupling portion (11) adjacent to the chucking portion (24) and is radially stiffened by a stiffening structure (12).

The invention relates to a rotary tool (1; 101; 201; 301; 401) for cutting large inside diameters at the outer circumference (2) of which at least one cutting edge (4; 104; 204) is arranged, comprising a support structure (10; 110; 210; 310; 410) which includes a supporting area (14; 114; 214) which indirectly or directly supports the cutting edge (4; 104; 204), and comprising a chucking portion (24; 124; 224; 324; 424) for coupling to a tool holder, wherein the support structure (10; 110; 210; 310; 410) is designed in light-weight construction and the area (14; 114; 214) of the support structure (10; 110; 210; 310; 410) indirectly or directly supporting the cutting edge (4; 104; 204) is limited regarding thermal expansion by a corset structure (12; 112; 212; 312; 412).

A lightweight cutting tool, such as a reamer, includes a front cutting body, a front cutting ring, a center tube, a rear cutting ring and a rear machine connection member. An arm assembly of the front and rear cutting heads includes one or more leading arms, one or more trailing arms and a cutting head supported by the leading and trailing arms. The leading arms and the trailing arms curve in opposite directions. To reduce weight and moment of inertia of the reamer, a cross-sectional area of the leading arms and the trailing arms is largest proximate the sleeve member and is smallest proximate the cutting head. In addition, the front cutting body, the front and rear cutting rings and the center tube may be made by additive manufacturing. Fluid can be transported entirely through the reamer to the cutting insert/workpiece interface and the guide pad/workpiece interface.

A cutting tool body includes a first member and a second member, both having a substantially cylindrical shape, and arranged such that a tool body central axis coincides with a central axis of each of the first and the second members. The first member has a tool characteristic of a first magnitude and the second member has the tool characteristic of a second magnitude, different from the first magnitude. The cutting tool body includes a transition member arranged between the first and second members and connected at a first end to the first member and at a second end to the second member. The tool characteristic in the transition member is of the first magnitude at the first end and of the second magnitude at the second end. The transition member has a transition region between the first and the second ends in which the tool characteristic transforms from the first magnitude to the second magnitude.
