An angle milling cutter is a specific type of rotary cutting tool whose main characteristic is that the cutting edges are arranged at a certain angle to the tool axis. This angle is fixed by the design of the cutter and is most often values such as 45°, 60° or 90°. It is used to create inclined surfaces, angled grooves, chamfered edges, so-called chamfers, or for milling specific shapes such as herringbone grooves. There are two basic types. The single-sided angle milling cutter has blades on only one tapered face and is used for machining one angled face. In contrast, a double-sided angle cutter has the cutting edges arranged symmetrically in a "V" shape, allowing two opposing inclined faces to be created simultaneously, typically in the production of V-grooves or gearing. In a double-sided cutter, the angle given, for example 60°, represents the total top angle clamped by the cutting edges. This tool finds application in situations where a well-defined angle needs to be machined that would be impossible or inefficient to create with a face or cylindrical cutter.
