          With helical peripheral teeth these cutters fillthe gap between
        
        
          normal shank cutters and the much larger facing cutters,this
        
        
          cuttter is better suited to light/medium cuts in a facing or stepping

            Shell End Mill (Roughing)
          
        
        
          As the name implies, these cutters with their helical teeth and
        
        
          roughing profile are particularly efficient in areas where large
        
        
          volumes of stock must be removed at high speed and where
        
        
          tough materials are to be worked.
