Premium Aluminum Titanium Nitride (AlTiN) coating provides quantum increases in productivity, either in terms of speed or longevity, with or without coolant.
Amana Tool 51609 Solid Carbide Spiral CNC Variable Helix for Stainless Steel, Steel, Titanium, Cast Iron and Cermet with AlTiN Coating 4-Flute x 1/2 Dia x 1 Cut Height x 1/2 Shank x 3 Inches Long Up-Cut CNC Corner Radius Bottom End Mill
4 Flute • Up-Cut
Unique variable design for faster speeds and feeds provides quiet operation & better finish. Amana's CNC variable helix tools are the superstars of carbide end mills for professionals and hobbyists alike. The CNC variable helix eliminates harmonic chatter, critical when surface finishes, part dimension tolerances& tool life are of utmost importance. For use with manual and automatic milling machines, as well as the most sophisticated CNC machines.
Excellent for cutting:
- Stainless Steel
- Cast Iron
- Cermet (composites in which ceramic materials and metals are joined together)
AlTiN Coating 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
These CNC variable helix end mills 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 a 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.
