Destiny Tool Raptor DVH End Mill

Raptor DVH
Raptor DVH - This group of tools evolved from our Cobra and Python end mills designed for high temperature alloy machining in materials such as Stainless Steel & Titanium. As you know, these softer gummy materials are often considered "difficult to machine" because of material buildup and and thermal expansion rates (material memory). 

The DVH, Double Variable Helix, design is unique to Destiny Tool.

What's a Double Variable Helix?

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. Our tools do that, but then we take an additional step...
Double Variable Helix
To further dampen the vibration, and dramatically reduce the harmonics that cause chatter in the workpiece, Destiny's DVH end mills have taken the next step in the design: EACH INDIVIDUAL FLUTE has a helix that varies!

As a result, our unique designs in both our Raptor DVH and our Raptor DVH 3/6 not only provide exceptional material removal rates and chip evacuation but most of the heat is removed with the chip!
We induce less heat in the base material which translates into better finish, faster part production AND longer tool life "in-the-cut". And, of course, we break up the harmonics so you have superior finishes even in your 'roughing' operations!
Raptor DVH Applications
  • Slotting
  • Heavy Profiling
Tolerance for Raptor DVH End Mills
Helix:  Each flute is different from the other; Each flute's helix also varies as depth of cut is increased.
Diameter Tolerance:  -0.000" to -0.002"
Shank Diameter Tolerance: +0.000" to -0.0003"

  • **LBS - Length Below Shank - This is measured from the tip of the cutting edged to the full diameter of the shank that engages in the toolholder. Typically, it is equal to or less than the cutting diameter.
  • *Shank Necked Diameter - This is the reduced neck diameter of the shank to prohibit rubbing of the shank along the wall in a deep pocket milling application.
