What are Lollipop cutters?

Lollipop cutters, also known as spherical ball cutters or undercutting end mills, are a type of cutting tool used in machining operations. As the name suggests, they are shaped like a lollipop, with a spherical head and a cylindrical shank.

Lollipop cutters are used for machining complex 3D shapes, particularly in hard-to-reach areas. The spherical head of the cutter allows it to reach angles and contours that traditional flat or angled cutters cannot, while the cylindrical shank allows it to be mounted in a standard tool holder.

Lollipop cutters are commonly used in the aerospace, automotive, and medical industries for machining complex parts from materials such as titanium and stainless steel. They are particularly useful for machining impellers, turbine blades, and other components with complex geometries.

The size of the lollipop cutter, including the diameter of the spherical head, can vary depending on the application. Lollipop cutters are available in a range of sizes and materials, including carbide and high-speed steel. They can be used in a variety of machining operations, including milling, contouring, and profiling.
