Abstract
A trepanning cutting tool for producing a through hole in a metal workpiece by cutting an annular groove about a removable core utilizes four (4) carbide cutting inserts. The cutting inserts are so arranged that they sever the radial span of the annular groove into six (6) relatively small segments which can be readily evacuated from the cutting region in the form of chips.
