The present invention relates to an indexable cutting insert for an end mill for machining of contours in a workpiece and to a milling tool. The cutting insert is asymmetrical in respect of a line through a hole in the cutting insert. The cutting insert includes two cutting edge portions. Each cutting edge portion comprises of a substantially straight cutting edge and a curved cutting edge along respective intersecting lines between a clearance surface and a chip surface. The curved cutting edges have different lengths. The cutting insert includes recesses in a bottom side of the cutting insert. The recesses are arranged on both sides of and at different distances from the hole of the cutting insert.

The present invention relates to a tool head preferably for milling. The tool head is connectable to a toolholder. The tool head includes a cutting portion and a mounting portion. The mounting portion includes an axial stop surface and a radial stop surface. Dimensions and tolerances of the axial stop surface and the radial stop surface are selected such that the axial stop surface will abut an axial stop on the toolholder to prevent axial movement of the toolholder relative to the tool head beyond the axial stop surface and the radial stop surface will be disposed proximate a radial stop of the toolholder to limit radial movement of the tool head relative to the toolholder when an integral fastening portion of the tool head and an integral fastening portion of the toolholder are fastened directly to one another and the axial stop surface and the axial stop abut.

Cutting tool and tool head

The present invention relates to a replaceable cutting tip and, more particularly, to such cutting tips attachable to the cutting tip holders by a threaded connection. The cutting tip for a cutting tool includes a working end portion disposed along an axis of the cutting tip and including one or more cutting edges for machining a workpiece, and a mounting portion disposed along the axis of the cutting tip. The mounting portion includes a frustoconical supporting surface tip portion and a frustoconical threaded portion. The present invention also relates to a cutting tool per se.

Cutting tool

The present invention relates to a tool and a male part for chip removing machining. The tool includes a male part and a holder for the male part. The male part includes a radial and axial supporting and positioning portion and a threaded portion. A largest diameter of the externally threaded portion is smaller than a smallest diameter of the radially and axially supporting and positioning portion. A transition portion is disposed along the axis of the male part between a radially largest portion of the radially and axially supporting and positioning portion and the externally threaded portion.

Tool for chip removing machining

The present invention relates to an indexable cutting insert for an end mill for machining of contours in a workpiece and to a milling tool. The cutting insert is asymmetrical in respect of a line through a hole in the cutting insert. The cutting insert comprises two cutting edge portions. Each cutting edge portion comprises a substantially straight cutting edge and a curved cutting edge along respective intersecting lines between a clearance surface and a rake face. The curved cutting edges have different lengths. The cutting insert has a bottom side and a first and a second opposite corner. The second corner is defined in plane view by a radius that is greater than, preferably at least twice as great as a radius of the first corner.

Indexable insert with corners with different radii

The present invention relates to a thread milling cutter, which includes a cutting head, having a holder with a number of cutting insert pockets, a number of threading inserts, which are received in the cutting insert pockets and an attachment integrated with the cutting head, which attachment is intended to be received in a tool coupling. The invention also relates to the holder per se and to a method for milling an external thread on a spigot. The holder is provided with an internal cavity, which has an extension both radially and axially with regard to a rotational axis of the thread milling cutter, and the cutting insert pockets are provided in the internal cavity.
