The milling cutter according to the present invention consists of insert holders where these insert holders project from a carrier disc which is adapted for clamping onto the spindle of a machine tool, and the individual holders are connected with one another by braces. Arms are provided between the holders and the carrier disc.

A rotary cutting tool is provided having a body and a fluid passage. The body has a shank portion and a cutting portion. The body extends lengthwise along a central axis between a shank end and a cutting end. The cutting portion includes a fluted section and a plurality of teeth extending axially outwardly from the fluted section at the cutting end. The fluted section includes a plurality of flutes disposed within an exterior surface of the fluted section. The cutting portion includes an internal cavity disposed within the fluted section and open to the cutting end. The internal cavity is defined by an interior wall surface. The cutting portion includes a plurality of channels disposed within the interior wall surface and open to the internal cavity. The fluid passage extends through the shank portion to the internal cavity.

A rotary cutting tool having a lengthwise extending central axis is provided. The tool includes a shank portion and a cutting portion. The cutting portion is connected to the shank portion, and includes a fluted section and a plurality of teeth. The fluted section includes a plurality of flutes disposed within an exterior surface of the fluted section. The cutting portion includes an internal cavity disposed within the fluted section and open to a cutting end. Each tooth includes a front side surface, an exterior side surface, an interior side surface, and an axial end surface. The front side surface intersects with the axial end surface to form an axial end cutting edge that extends radially between an outer radial tip and an inner radial tip, and the outer radial tip is disposed axially outside of the inner radial tip.

A rotary cutting tool cutting insert is provided that includes front, aft, exterior, and interior side surfaces, an axial end surface, and a base surface. The exterior side surface intersects with the front side surface. The interior side surface intersects with the front side surface. The axial end side surface intersects with the front side surface at an axial end cutting edge, with the exterior side surface at a first outer axial edge, and with the interior side surface at a second outer axial edge. The base surface intersects the front, exterior, and interior side surfaces and the aft surface. The base surface intersects the front side surface at an inner edge. An outer radial tip is disposed at a first heightwise distance from an inner edge, and an inner radial tip is disposed at a second heightwise distance from the inner edge.

Arms are provided between the holders and the carrier disc,

The milling cutter according to the present invention consists of insert holders (2) where these insert holders (2) project from a carrier disc (1) which is adapted for clamping onto the spindle of a machine tool, and the individual holders (2) are connected with one another by braces (3). Arms (5) are provided between the holders (2) and the carrier disc (1).

A rotary cutting tool has an insert receiving pocket with a cutting insert removably secured therein and an adjustment recess rearward thereof having a radially outward facing recess side surface and an adjustment tongue spaced apart therefrom by a first inner passage. The adjustment tongue extends rearwardly from a tongue root to a tongue tip and includes a tongue through bore. The tongue root has a shoulder surface facing in the forward direction and the cutting insert is in contact with the shoulder surface. An adjustment screw extends through the tongue through bore and engages the recess side surface, and rotation of the adjustment screw causes axial displacement of the cutting insert in a forward direction. An imaginary straight line in the first inner passage intersects a recess rear end surface formed on a first body sub-portion of the cutting body which is integrally formed with the adjustment tongue.

A diamond tool comprising a tool shank and a tool head, which is fixed on the tool shank and which is formed by a layer of material interspersed with diamonds at least in sections, the layer of material interspersed with diamonds at least in sections being directly integrally bonded to the tool shank by an electroplating deposition process and the tool head having a recess on the front side, so that in cross-section the tool head has the form of a circular ring in the area of the free end, the tool head forming a hollow milling cutter and a wall forming the hollow milling cutter and having the form of a circular ring consisting only of a nickel-diamond material that is grown by electroplating.

In one embodiment, a cutting tool includes an insert that includes a cutting edge at at least one part of a portion where two surfaces intersect. The cutting tool further includes a holder capable of rotating about a rotational axis. The holder includes a pocket including: a placement portion where the insert is positioned; and a cutout portion is adjacent to the placement portion and positioned further forward in a rotational direction than the placement portion. The holder further includes an inflow port that opens at at least one part of the holder, a first flow path positioned in the interior of the holder, and an outflow port positioned at the pocket. The cutout portion includes a recessed portion.
