Amana 51607 CNC Spiral Multi-Helix Corner Radius Bottom 3/8 Dia x 7/8 x 3/8 Shank x 0.020 Radius Solid Carbide AlTiN Coated Up-Cut End Mill

Amana Tool's multi-helix tools are the superstars of carbide end mills for professionals and hobbyists alike. The multiple helix eliminates harmonic chatter, so critical when surface finishes part dimension tolerances and tool life are of the utmost importance. Premium Aluminum Titanium Nitride (AlTiN) coating provides quantum increases in productivity either in terms of speed or longevity with or without coolant.
They are outstanding tools for peripheral milling and can take aggressive cuts along the full length of the overall flute length with no issues. They last much longer than general purpose end mills partly because they are coated partly because they dampen vibration which tends to break a sharp cutting edge down very quickly. For use with manual and automatic milling machines, as well as the most sophisticated CNC machines.

4 Flute unique variable design for faster speeds and feeds.
Quiet operation & better finishes.
 
Excellent for cutting:

Stainless Steel
Titanium
Cast Iron


Steel
Cermet*




*Cermets are composites in which ceramic materials and metals join together.




AlTiN coating has many benefits:
 

Extra wear resistance
Allows for faster feed and speed rates
Cutting edge protected from wear
Better chip evacuation
Less heat build up
Superior cutting quality and extended tool life


 
WARNING: Inspect cut quality and adjust feed and speed accordingly. Care should be taken to observe proper feeds and speeds according to the workpiece material to avoid damage.
 
Note: For optimal results and extended tool life use mist lubricant system or air cooling.
