摘要：
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).
