ABSTRACT:
A high-speed end-milling router for ramping entry into a workpiece has plate-like hard metal cutting inserts fitted in pockets milled in chip gullet surfaces to present the insert at a desired axial rake angle and with radially inwardly and outwardly facing cutting edges. Each insert is secured in its pocket by two countersink headed machine screws whose holding power against centrifugal dislodgement of the insert is reinforced by a projection from the seating surface of the pocket extending into a blind recess molded in the undersurface of the insert.
