Variable Index End Mills

Today's high performance end mills utilize variable index and/or variable helix flute designs to yield the maximum metal removal rates possible.  These mills also use eccentric grinding on the diameters of the mills to give them strength and stability.  The vari-mill geometry reduces vibrations during the cutting process which allows greater feed rates and/or depths of cut.  These mills are available in lengths from stub to extra long and flute counts from 4 to 6.
