Beschreibung
Zusammenfassung:	A rotating type excavating tool or cutter in which a cutter body is formed with a blind hole into which a spindle extends with antifriction bearings interposed between the spindle and the body with a clamp nut on the spindle at the bottom of the blind hole. Access is had to the nut for tightening the nut up during assembly, or for loosening the nut for disassembly purposes by at least one hole formed in the cutter body in the range of the bottom of the blind hole and which are plugged after the nut is tightened to prevent foreign matter from getting into the blind hole in the cutter body.
