For machining low carbon steels, stainless steels, and heat resistant super alloys, 35°-40° helix end mills are best. 37°-45° 37°-45° helix end mills are the go-to for milling non-ferrous soft materials, like aluminum, copper, and plastics. 60° For specific applications and higher feed rates with better finishes, try a 60° helix end mill.

The helix angle is the angle of flutes. These angles define the cutting force, vibration, and heat generation during machining. Most end mills have 30° helix angles. The more degree of helix angle, the smoother the material's finished surface but the weaker the end mill and unable to sustain heavy cutting depths with high feed rates.

As machining people, why do we care about the lead angle? When turning a thread with a typical laydown insert, the best practice is to tilt it by the lead angle size. It ensures symmetrical relief on both sides of the insert flanks. All threading tools suppliers provide an assortment of shims to tilt the inserts to all the needed angles.
