Milling cutter with a cord of a special tooth profile

A milling cutter with at least one peripheral cutting edge 4 disposed on its periphery, the peripheral cutting edge 4 being configured as a profile of spaced-apart teeth 7 that forms a so-called cord; wherein each of the teeth 7looking from the flute in a direction opposite to the cutting direction onto the cutting edge portionforms a cutting edge portion SK composed of several different radii, i.e. of at least one larger radius R1 forming the predominant part of the cutting edge portion of the respective tooth 7 and a smaller radius R2, which is preferably immediately adjacent thereto on both sides.

Multi-flute endmill

A multi-flute endmill including a cutting edge part having multiple cutting edges and flutes formed between adjacent cutting edges in a rotation direction around the tool axis O. A rake face of each cutting edge is formed from a rake face of an end cutting edge from the tool axis O side to the outer peripheral side of a shank, an adjacent rake face of a corner R edge that forms a surface different from the rake face of the end cutting edge, and an adjacent rake face of a peripheral cutting edge that forms a surface different from the rake face of the corner R edge. A gash is formed between the rake face of the end cutting edge and a flank of an end cutting edge that is adjacent on a forward side thereof in the rotation direction R.
