• RedLine XHP Variable 5-Flute tools offer optimum metal removal rates. By controlling the vibration and
chatter through a unique dampening geometry, and through the application of our advanced heat
resistant coating over a fine micro-grain carbide substrate, our tools can handle faster speeds and feeds
with excellent tool life in even the most difficult to machine materials like Stainless and Titanium.
• These tools can be optimized by using High Efficiency Machining technology.
• Used to Ramp, Plunge, Slot, Rough and Finish Profiles and can be found on pages 62-78.
