Abstract

A sealing plug is insertable into a rear end of a cutting shaft on which a cutting insert is mounted. The plug forms an internal passage for conducting cooling liquid to a center duct of the shaft. The plug includes a sleeve portion insertable into the duct, and a radial flange which supports an elastically flexible sealing member that can be removed. The sealing plug is capable of multiple uses, e.g., a first use wherein the cutting shaft is mounted within an adapter and the sealing member seals radially outwardly against a surface of the adapter, and a second use wherein the cutting shaft is mounted in an open-ended bore of a holder (i.e., no adapter is used), the sealing member is removed, and sealing is effected by a tight-fit of the sleeve portion within the duct of the cutting shaft. By removing the sealing member, the maximum outer diameter of the plug is reduced to facilitate movement of the cutting shaft through the bore of the holder.
