End Mill Cutter Ideal for Machining Undercuts, Deburring and Multi-Axis Machining

Big Kaiser’s Lollipop from Sphinx, the latest addition to its end mill cutter lineup, is especially useful for machining undercuts, deburring and multi-axis machining.

Lollipop cutters, also known as undercutting end mills, can be useful for certain situations. Undercuts are commonly known to be difficult to machine with a standard end mill, especially on three-axis machines. The Lollipop can be used in three-axis and five-axis applications, although five-axis applications are more common due to the operator’s ability to rotate and index the tool for any given reason, the company says.

By using these end mill cutters, shops will see cost and time savings, according to the company. This tool is designed to provide a great surface finish due to its edge-breaking capabilities—a critical final step to create a part that looks and feels like a finished product and is safe to handle.

The under cutting angle used in most operations is between 220 degrees and 300 degrees, and the corresponding angle for the Lollipop from Sphinx is 270 degrees. Although frequently associated with a singular use, lollipop cutters are versatile tools for a variety of shopfloor operations.
