Abstract:
A modular cutting tool includes a cutting head, a shank and a mechanism which assists in assembling and locks the cutting head to the shank. The cutting head includes a cutting portion rotatable about a central longitudinal axis and a cylindrical skirt extending axially from the cutting portion and terminating at a contact face disposed perpendicular to the longitudinal axis. The skirt has a number of curved inner surfaces which generally define a bore disposed about the longitudinal axis. The shank includes a cylindrical portion of a first diameter disposed about the central longitudinal axis and a central protrusion disposed in the bore of the cutting portion. The central protrusion has a second diameter less than the first diameter and extends longitudinally from a contact face disposed perpendicular to the longitudinal axis at a leading end of the cylindrical portion.

Claim (Index 20):
The shank of  claim 17 , further comprising a mechanism comprising:\n a first locking drive key; a second locking drive key; and a differential screw member disposed through the transverse bore and having a first threaded portion disposed at or about a first end and a second threaded portion disposed at or about a second end opposite the first end, wherein the first threaded portion includes a first plurality of threads disposed in a first direction and second threaded portion includes a second plurality of threads disposed in a second direction, opposite the first direction, wherein the first locking drive key and the second locking drive key each comprise:\n a main body portion generally disposed within a respective one of the first alcove or the second alcove, the main body portion having:\n an inner face facing toward the longitudinal axis; \n an outer face disposed opposite the inner face; \n a leading side face which extends between the inner face and the outer face on a leading side of the main body portion when the shank is rotated about the longitudinal axis in a cutting direction; and \n a trailing side face which extends between the inner face and the outer face on a trailing side of the main body portion when the shank is rotated about the longitudinal axis in the cutting direction; \n \n a central projection extending from the inner face of the main body portion radially inward toward the longitudinal axis; and \n a lateral projection extending generally tangentially with respect to a reference circle centered about the longitudinal axis from the trailing side face of the main body portion at or about an upper portion of the main body portion, \n wherein the first locking drive key further includes a threaded aperture defined through the main body portion and the central projection thereof which is threadingly engaged with the first threaded portion of the differential screw member, wherein the second locking drive key further includes a threaded aperture defined through the main body portion and the central projection thereof which is threadingly engaged with the second threaded portion of the differential screw member, and wherein the differential screw member further includes a feature formed in either or both of the first end or the second end thereof which is structured to be engaged by a correspondingly formed tool for rotating the differential screw member about a central longitudinal axis thereof.
