TYPE 3320
Flute long carbide tips brazed to hardened alloy steel bodies.
For milling primarily cast iron and malleable iron. However, they can be used on other materials except steel. The large capacity of the 15° spiral flutes permits faster chip removal while allowing smoother finishes. Also the high spiral provides longer tool life. More flutes than Type 3375 for use where less feed rate per flute is required but table feed is maintained for same productivity.

Upsharp tool diameter tolerance: +.005"/-.000".
