Nov 17, 2015 The higher the helix angle, the greater the proportion of axial force. On a 0 degree end mill (straight end mill), all the force is radial. Also, as each edge comes in contact with the work piece material there is a sudden shock load. This causes vibrations, poor surface finish on the part, and poor tool life. On an end mill with a 30 degree
ContactMar 05, 2021 The basic edge shapes of carbide end mills has two types: straight shape and spiral shape. The helix angle can be divided into 30°, 45°, 50°, etc., and there are various types.
