What is helix angle for 60hrc end mills?

The end milling cutter depends on the feed direction, feed along the axis (I call vertical milling) and perpendicular to the axis (I call transverse milling). The main deflection angle is different, which is mainly due to the different main cutting edges.

The most commonly used end milling cutter is transverse milling. At this time, the circumferential edge is the main cutting edge, and the included angle between it and the projection of the feed direction on the base plane (the plane composed of the point you analyze and the milling cutter axis) is the main deflection angle (note the projection).

Generally, the helix angle mainly affects the blade angle.

Only 60 degrees is the helix angle of 45 degrees, and the rest are all 35 degrees.
