ABSTRACT:
The invention is directed to an improved cutting tool point. In the preferred embodiment, the cutting tool is comprised of a marginal end portion (15), adapted to selectively removed material from a work piece when the tool is moved relative to the work piece and having a leading cutting lip (16), a trailing dam (18), a recessed surface (19) extending into the marginal end portion between the cutting lip and the dam, and a coolant hole (20) communicating with the recessed surface, such that the recessed surface forms a reservoir (40) for coolant (36). The present invention also discloses a marginal end portion having an axis of rotation (42), at least one flute (21), and at least one chip-forming notch (31) extending from the flute into the marginal end portion and beyond the axis of rotation. The present invention also discloses a marginal end portion having a chip former (37) and a chip breaker (32). The present invention also discloses a marginal end portion having a land (22) composed of an upper portion (33) and a lower portion (34), the upper portion having a land recess (35) to accommodate coolant and to provide a fluid bearing between said upper portion and said work piece.
