Variable helix. The variable helix end mill has unequal flute spacing at various points along the tool's cutting length. Unequal flute spacing helps dampen the vibration generated by the milling process. This vibration dampening enables faster feed rates and improved surface finishes.
HARVI™ Line Solid Carbide End Mills. Primary Application HARVI takes high-performance roughing, semi-finishing, slotting, and profiling to the next level.
Dec 29, 2014 · Walter-Prototyp also has a 3 (and 4) flute end mill specific for steels, the ProtoMax ST. It's unbelievable how they perform with the ZrN over TiAlN coating, and both versions also have the variable flute depth and the 4-flute has unequal flute index.

[PDF]Tools with unequal helix angles can lead to an increase of process stability. In this paper, a method to calculate the process forces of end mills with complex geometries is
An unequal helix-angle end mill includes a cutting part and a handle part. The cutting part is provided with a plurality of flutes, each spirally extending from the bottom end to the handle part. The face of each flute facing the cutting rotation direction is a rake face, wherein the rake face and an outer peripheral face of the cutting part are intersected to form an outer peripheral blade ...
Aug 29, 2012 · Our Philosophy on End Mills: Geometry Take a close look at our end mills... under a microscope. ... Unequal Flute Spacing on a Raptor 3/6: ... and he told me that he needed to buy a helix end mill in order to finish the job. He is going to have to shop around his local tool stores. Hopefully he can find what he needs.
End Mills Grooving Systems ... The convex form and variable pitch of the helical cutting edges results in a stable countersinking process with minimal vibration, even when using a hand drill. ... Three different convex cutting edges in combination with three unequal helix angles enable extremely stable and low-vibration cutting processes ...
Single Variable Helix A typical variable helix end mill consists of unequal flute spacing at various points along the cutting edge of the tool.The unequal flute spacing dampens vibration that is generated by the milling process. This vibration dampening permits faster feed rates and improved surface finishes when properly applied.
