Cutting Diameter: 1/2"
Corner radius, four variable indexed and individually designed RH flutes


The Harmon-I-Cut is our revolutionary solid carbide advanced performance end mill. The Harmon-I-Cut name refers to the tool's unvelievable ability to both rough and finish mill parts at unheard-of speeds and feeds.

The rates are either on the periphery or in slot milling with finishes of 15 to 20 RMS or better and are accomplished through the total elimination of harmonics in the cut.
