5 Flute Variable Helix End Mills for Steel and Cast Iron

The 5 flute end mills for steel can be run at increased
speeds and feeds over the 4 flute end mills. The
approximately 38° Helix Angle pulls chips quickly
and the Variable Index with Individual Helix of
the teeth eliminates vibration from harmonics to
allow deep fast cuts. The deep gashes on the end
face are particularly deep and the Eccentric Relief allows for aggressive ramping of the end mills. For machining
steel, AlTiN is a standard and capable coating. For improved performance and tool life in steel and tool steel we
recommend FerroCon and for difficult to machine Stainless Steels we recommend InoxoCon.
* For CHAMFERED end mills enter a C as the first character in the part number. For example a 1/2” 4 flute uncoated
end mill will have a part number or C-FT4-500. Standard Chamfer is 5% of Diameter. Any size can be requested.
* For Radius end mills enter an R as the first character in the part number. For example a 1/2” 4 flute uncoated end
mill will have a part number or R-FT4-500. Standard Radius is 5% of Diameter. Any size can be requested.
* HP at the end means AlTiN Coated, F means FerroCon and I means InoxoCon Coated
