Considering the helix angle is essential since it influences chip evacuation efficiency, component polish, tool life, and cycle times. End mills typically have straight or helical edges. Segments of 30°, 45°, and 50° make up the helix angle. Helix edge end milling cutters have been extensively used in milling because they offer light cutting ...

The helix angle is the measure of angle between tool's centerline and straight line tangent with the cutting edge. The higher the helix angle, the more easily chips of softer materials can escape. Therefore, end mills with comparatively higher helix angles than standard end mills are used. The angle with 35°, 40°, or 45° are preferred.
