A slotting cutter including a support disc rotatable in a predetermined direction on a central axis. The support disc is of a generally cylindrical shape having a first side and a second side, and an outer periphery. A plurality of pockets including a cartridge assembly are staggered about the outer periphery of the support disc and include a cutting insert secured to each cartridge assembly. Each cutting insert includes at least one cutting edge. The cutting insert extends laterally outwardly beyond the first side of the support disc and is spaced from the second side of the support disc such that the cutting edge of adjacent inserts are positioned to laterally overlap thereby providing an increased effective cutting path width.

Slotting cutter

A three dimensional mill capable of plunging, ramping, circle interpolating and other milling processes while providing a finished surface not in need of finish grinding. The milling cutter includes cutting inserts of a modified design including flats separating rounded corners of a two radius design. Each insert also includes a rail that is secured to the milling cutter along a longitudinal surface that is radial to the axis of the milling cutter at any cross sectional plane.
