Abstract: A turning tool includes a tool body having an insert seat that accommodates a cutting insert and a mounting means for mounting the cutting insert at the tool body. A guiding block is movably mounted between a first position and a second position at the tool body. A fluid passage is arranged to eject a jet of cooling fluid from an inlet end to at least one outlet onto a clearance surface associated with a cutting edge of the cutting insert. When the guiding block is in the first position the jet of cooling fluid is ejected along a first line and when the guiding block is in the second position the jet of cooling fluid is ejected along a second line, wherein the first line and the second line have different orientations and intersect each other at a position in a downstream direction from the outlet.

Abstract: A method for producing a coated cutting tool includes depositing a 0.5-10 μm nitride layer, which is a nitride of one or more of Ti, Zr, Hf, V, Ta, Nb, Si, Cr and Al, onto a substrate followed by depositing Al or Al+Me, further followed by depositing a 0.1-5 μm oxide layer being an (AlaMe1-a)2O3 layer, 0.05≤a≤1, wherein Me is one or more of Ti, Mg, Ag, Zr, Si, V, Fe, Hf, B and Cr, said layers being deposited by magnetron sputtering. Also, a coated cutting tool including a substrate with a coating having the nitride layer and oxide layer. The coating has inclusions of (Al,Me,O) in the oxide layer at the interface between the nitride layer and the oxide layer, and/or a layer of (Al,Me,O) situated in between the nitride layer and the oxide layer.

Abstract: A coated cutting tool having at least one rake face and at least one flank face and a cutting edge therebetween includes a substrate and a coating. The coating has a (Ti,Al)N layer, the (Ti,Al)N layer having an overall atomic ratio Al/(Ti+Al) of >0.67 and ≤0.85, wherein the (Ti,Al)N layer shows a distribution of 111 misorientation angles, the 111 misorientation angle being the angle between a normal vector to the surface of the (Ti,Al)N layer and the direction that is closest to the normal vector to the surface of the (Ti,Al)N layer. A cumulative frequency distribution of the 111 misorientation angles is such that—≥60% of the 111 misorientation angles is less than 10 degrees.

Abstract: A coated cutting tool includes a substrate and a coating. The coating has a (Ti,Al,Si)N layer, which has a periodical change in contents of the elements Ti, Al, and Si, over the thickness of the (Ti,Al,Si)N layer, between a minimum content and a maximum content of each element. The average minimum content of Ti is from 14 to 18 at. % and the average maximum content of Ti is from 18 to 22 at. %. The average minimum content of Al is from 18 to 22 at. % and the average maximum content of Al is from 24 to 28 at. %. The average minimum content of Si is from 0 to 2 at. % and the average maximum content of Si is from 1 to 5 at. %. The remaining content in the (Ti,Al,Si)N layer is a noble gas in an average content of from 0.1 to 5 at. % and the element N.

Abstract: A press tool and a method for forming a cutting insert green body. The press tool includes a first and a second core rod. Both core rods are movably arranged along an axis. When both core rods are in a press position, their respective contact surfaces contact each other and when both the first and second core rods are in a release position, their respective contact surfaces are separated. The first core rod includes a base body having a forwardly facing abutment surface and a piston having a shaft and a head. The piston is movable to a plurality of extended positions and to a retracted position, in which the abutment surface of the head abuts against the abutment surface of the base body. When both the first core rod and the second core rod are in their respective press positions, the piston is in the retracted position.

Abstract: An indexable cutting insert, arranged for being mounted in an insert seat of a tool body of a shoulder milling tool, includes a triangular top surface, a triangular bottom surface, and three circumferential surfaces extending between the top and bottom surface. On each side of the cutting insert an individual one of the three circumferential surfaces extends along an edge of the triangular top surface and along an edge of the triangular bottom surface. The cutting insert includes at each of the top and bottom surfaces three cutting corners, three main cutting edges and three minor cutting edges. Each cutting corner connects a main cutting edge and a minor cutting edge. Each of the cutting corners, each of the main cutting edges and each of the minor cutting edges are provided at an intersection between the top surface or the bottom surface and one of the circumferential surface.

Abstract: A coated cutting tool including a substrate and a single layer or multi-layer hard material coating is provided. The substrate is selected from cemented carbide, cermet, ceramics, cubic boron nitride (cBN), polycrystalline diamond, steel or high-speed steel. The hard material coating includes at least one layer of gamma-Al2O3, exhibiting particularly high hardness and reduced Young's modulus. The gamma-Al2O3 layer of the coated cutting tool is obtainable by means of a reactive magnetron sputtering process using at least one Al target, wherein the deposition is carried out using a reaction gas composition of argon (Ar) and oxygen (O2) at a total reaction gas pressure within the range from at least 1 Pa to at most 5 Pa, at an O2 partial pressure within the range from 0.001 Pa to 0.1 Pa, and at a temperature within the range from 400° C. to 600° C.

Abstract: A compression tool, a cutting plate and a method of producing a cutting plate by multiaxial pressing a powder mixture of a hard metal component and a binder to form a green body is provided. After pressing, the body has two parallel main surfaces and a peripheral edge surface extending between and connecting the main surfaces. The main surfaces include depressions, such that cutting edges are formed at the intersection of the bottom of the depressions and at least a part of the edge surface. A heading tool includes a main punch and an independently moveable form punch. In a first pressing step, the form punch is moved towards the powder mixture to form a preliminarily compressed portion. In a second step, the main punch and the form punch are both moved towards a final position to provide the green body with its final dimensions including the depressions.

Abstract: A drilling tool includes a tool body having a center axis defining a longitudinal direction of the drilling tool. The tool body has an axially forward end and an axially rearward end, the distance in the longitudinal direction between the forward end and the rearward end defining a length of the drilling tool. At least two indexable cutting inserts are arranged at the axially forward end, a first indexable cutting insert being arranged at a radially inner position and a second indexable cutting insert being arranged at a radially outer position. The tool body includes a first flute portion extending axially rearward from the first indexable cutting insert and a second flute portion extending axially rearward from the second indexable cutting insert. The first flute portion transitions into the second flute portion at an axially forward transition area of the tool body, thereby forming only one flute of the tool.
