Abstract: Apparatus for manually sharpening the bottom, radially divergent, flute ends or cutting edges of an end milling cutter (hereinafter referred to as an "end mill") which apparatus includes: a stationary, beveled disc-type or plain grinding wheel mounted for rotation about a horizontal axis (or y-axis), so as to present the face of the wheel to an operator, and a tool-holding fixture having a base member mounted on the worktable of a conventional tool grinder. The worktable of the grinder is capable of movement along three axes, namely a longitudinal axis (or x-axis), a horizontal axis (or y-axis) toward and away from the circular face of the disc, and a vertical axis (or z-axis), by manual manipulation of individual table-adjusting wheels. The fixture includes a workhead mounted on a carriage which in turn is translatably mounted for linear to and fro motion, on a base member with bearing means. The workhead is mounted on the carriage for pivotable movement about a longitudinal axis (x-axis).
