What is a double angle cutter used for in CNC milling?

A double angle cutter is specifically designed for creating chamfers or grooves in machining operations. This type of cutter has two cutting edges that are set at an angle, allowing it to effectively slice into the material to produce angled features. When machining parts where precise angled surfaces or grooves are required, the double angle cutter can efficiently create these shapes in a single pass, which is particularly advantageous in terms of both time and tool wear compared to other methods.

While creating a flat surface, drilling holes, and shaping edges can be accomplished with various types of cutters, they are not the primary function of a double angle cutter. Flat surfaces are typically achieved with flat end mills, drills are used for boring holes, and shaping edges generally involves different profiles. Thus, the unique application of the double angle cutter makes it particularly suited for creating distinct chamfers or grooves, validating the accuracy of the chosen answer.
