Tech Info -
• RedLine XHP Variable Helix 3-Flute tools are designed for fast metal removal. We control vibration and
chatter through a unique dampening geometry and can handle faster speeds and feeds generated by the
application of our AlCrN coating.
• Designed to run in a wide range of materials from cast irons and steels to titanium and high temperature alloys.
• These Extra High Performance tools can be found on pages 33-40.
