Abstract
A workpiece-shaping tool assembly has a drive shaft having an outer end centered on and rotatable about an axis and a tool fittable with the end of the drive shaft. A torque coupling is formed by shaft splines formed on the drive shaft and tool splines formed on the tool, complementary to the shaft splines, and interfitting with the shaft splines. A radial-force coupling is formed by an inner cylindrical shaft surface formed on the shaft axially offset from the shaft splines and centered on the axis and a respective inner cylindrical tool surface formed on the tool offset from the tool splines, centered on the axis, and radially juxtaposed and engageable with the inner shaft surface.
