ABSTRACT:
A reconditioned tool comprises a cylindrical insert cut from a damaged tool, such as a hog mill, with a milling face formed on one end and a transverse dovetail tenon cut in the other end. The dovetail tenon engages a transverse dovetail mortise in the end face of a cylindrical holder. A transverse slot in the holder splits the end of the holder into two axially extending end sections each of which includes one-half of the dovetail mortise. A clamping device, such as a bolt, draws the two end sections of the holder together to pull the insert firmly against the end faceof the holder through wedging action of the two halves of the dovetail mortise against the dovetail tenon. A locking pin inserted through aligned transverse grooves in the holder and insert prevents a lateral displacement of the insert relative to the holder.
