1/2 x 3” Solid Carbide Flat (Square) 3 Flute End Mill center cutting with a .500 (1/2″) cutting tip and a 1-1/4 inch length of cut.

This tool features a 45 deg helix which makes it ideal for finishing due to its high shear angle and cutting toughness. 3 Flute end mills are perfect for milling aluminum and other non-ferrous materials, they also tend to reduce vibrations during the milling operation.

These tools are coated with a proprietary high performance *Astra coating* that allows higher speed & feed rates as well as extended tool life & increased lubricity in abrasive material.

Sebastian ★★★★★

The 45-degree helix on this bit clears chips like a dream, and the 1-1/4 inch cutting length gives me plenty of reach for deep passes. Cut through some tough aluminum plate without any chatter, and the AstraHP coating still looks brand new.

Olivia ★★★★★

Waited ages for a bit that could handle deep slotting in 6061 without chatter — this 3-flute AstraHP-coated beast did it clean on the first pass. Length of cut is generous too, saved me from multiple spring passes.

Natalie ★★★★★

The 45-degree helix really shows on aluminum—chips clear so fast I barely hear the cut, and the 1-1/4 inch length of cut handled a deep pocket without flexing. It’s the smoothest finish I’ve gotten from a 3-flute so far.
