3 Flute, Corner Radius - 45° Helix

End Mills for Aluminum Alloys & Non-Ferrous Materials

H45AL-3 | Carbide End Mills

The high helix on the H45AL-3 increases shearing action, which leaves a cleaner finish on your part, while its corner radius profile promotes strength for prolonged tool life in both traditional roughing and High Efficiency Milling toolpaths.

Designed with a high helix for improved part finish and shearing action
Cylindrically ground to maintain edge strength
Center cutting
Excellent performance in High Efficiency Milling (HEM)
h6 shank tolerance for high precision tool holders
Zplus coating for maximum performance in aluminum and non-ferrous alloys
Solid carbide end mills
