摘要： A tangential reversible cutting blade, comprising: a prismatic body which is bordered by two opposed, identically shaped first surfaces and four identically shaped, interposed lateral surfaces, four equal-length main cutting edges on each of the first surface which are defined with one lateral face each, a raised web on each lateral surface with the four webs being symmetrical with a central plane through the lateral surfaces, a through mounting bore coaxial with the axis through the centres of the first surfaces, metal-cutting faces on the lateral surfaces which are defined by fillets adjacent to the main cutting edges on either side of the associated web, and cutting-tool flanks on the first surfaces which are defined by a spherical surface shape of the first surfaces adjacent to the main cutting edges.

摘要： A disc-shaped mill cutting tool, with a disc-shaped main body which has a central axial through bore for the accommodation of a drive shaft as well as a plurality of pockets for the accommodation of cutting inserts on its perimeter, wherein chip spaces are associated to the pockets and a channel system is arranged between the central through bore and the chip spaces for the passage of cooling fluid which emerges in the chip spaces, characterised in that the disc-shaped main body is formed by at least two sub-discs coaxially sitting close together, which form a concentrically arranged ring channel between themselves, which is connected to the through bore via at least one connection channel, and the ring channel is connected to the chip spaces via relatively short bore portions.
