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.
