Abstract: Mounting assemblies for cutting tools are disclosed that include a base and an adapter block. Mounting assemblies are provided with self-fixturing features to provide a desired mounting position and to restrict movement of the adapter block with respect to the base prior to bonding. The self-fixturing features provide the ability to perform repeatable and consistent bonding of the adapter block to the base.

Abstract: A cutting tool holder-base assembly (399) has a base (400). The base (400) is adapted to attach to a surface (40) of a rotatable driving member (38). The tool holder-base assembly (399) includes a cutting tool holder (500) with head region (502) containing a cutting tool bore (506), and a shank region (504) with a distal end (524). The shank region (504) has an alignment notch (528) presenting an alignment surface (530) at the distal end (524). The assembly (399) further has a base (400), which contains a tool holder bore (418) and a transverse passage (430) intersecting the tool holder bore (418). There is an elongate pin (436) in the transverse passage (430). The elongate pin (436) has an exposed portion (440) thereof passing through the tool holder bore (418) wherein the cutting tool holder (500) is able to enter completely the tool holder bore (418) of the base (400) when the alignment surface (530) is in alignment with the exposed portion (440) of the elongate pin (436).

Abstract: A cutting bit retention assembly (399) that includes a cutting bit holder (500), which receives a cutting bit (58) and has shank (504) that extends into a bore (418) in a support (400). The shank section (504) of the cutting bit holder (500) presents a surface (530) defined by a notch (528) that selectively cooperates with a retention pin (670). A transverse bore (430) in the support (400) carries the retention pin (670). The retention pin (670) is selectively movable to any one of several positions. One position is a non-retaining position wherein the retention pin (670) does not engage the notch surface (530). Another position is a retaining position in which the retention pin (670) engages the notch surface (530) to urge the cutting bit holder into the cutting bit holder bore (418). Still another position is an ejecting position in which the retention pin (670) engages the notch surface (530) to urge the cutting bit holder (500) out of the cutting bit holder bore (418).
