Cutting Tool With Flat Sided Groove For Non Rotation

A cutting tool assembly comprising:

• a cutting bit having a head comprising of a body located longitudinally below a cutting element and a shoulder located below said body, and a cylindrical shank that has an outer wall having a longitudinal length that extends in a longitudinal direction from below said shoulder, and wherein said cylindrical shank has a clip groove that is located on said outer wall of said cylindrical shank, and wherein said clip groove has at least one surface that is one selected from the group consisting of at least one flat side, at least one convex surface, and at least one concave surface;
• a cutting bit holder having an internal cylindrical bore and a front face, and wherein said internal cylindrical bore has a mouth, and wherein said internal cylindrical bore has a longitudinal length that extends in a longitudinal direction of said cylindrical shank;
• a washer having a center hole, and wherein said washer is located between said shoulder of said cutting bit and said front face of said cutting bit holder;
• and
• a cylindrical retainer sleeve having an outer wall, said cylindrical retainer sleeve has a longitudinal length, and a split that is located on the circumference of said outer wall that forms an opening on said cylindrical retainer sleeve and wherein said split extends in a longitudinal direction along the longitudinal length of said cylindrical retainer sleeve, and wherein said retainer sleeve having at least one internal radial tab having a first convex portion,
• wherein said cylindrical retainer sleeve fits inside said internal cylindrical bore of said cutting bit holder,
• wherein said cylindrical shank fits inside said cylindrical retainer sleeve, and
• wherein said at least one internal radial tab biases against and is in juxtaposition to said at least one surface of said clip groove to inhibit axial movement and radial rotation of said cylindrical shank of said cutting tool.
