Abstract: A cutting tool assembly includes a tool body having a major flare diameter portion disposed adjacent the cutting end of the cutting tool and a puller groove disposed below the major flare diameter portion. A compressible sleeve is disposed about a shank portion of the cutting tool, which is mounted in a tool holder. A washer is fitted about the compressible sleeve, and acts as one of the sides of the puller groove. The location of the puller groove below the major flare diameter portion allows for the cutting tool to be made by cold forming, or the like.

Abstract: A retainer sleeve for retaining a rotary bit includes a longitudinally slit cylindrical portion defining a longitudinal axis, and at least four circumferentially spaced tabs deformed generally radially inwardly from the cylindrical portion. The sleeve is formed from a sheet of spring steel having a thickness of at least 0.048 inches. Each tab comprises a connector section inclined from the cylindrical portion in a generally radially inward and longitudinally rearward direction and a keeper section extending rearwardly from a free end of the connector section. The keeper section includes a first flat surface facing the axis and oriented parallel thereto, and a second flat surface facing rearwardly and oriented perpendicularly to the axis.

Abstract: A cutting assembly that includes a block that has a body that contains a block bore. A sleeve has a body that contains a bore that has an axial forward end and a forward surface surrounding the bore at the axial forward end thereof. The sleeve further contains at least one scallop beginning at extending in an axial rearward direction from the forward surface. There is a cutting tool rotatably contained within the bore of the sleeve. There is a non-rotatable washer that has a washer body that has a peripheral edge wherein the washer body contains at least one indention adjacent to peripheral edge. The indention of the non-rotatable washer is received within the scallop.
