End Mill Selection Assistance
Help with choosing the best tool based on your application.
The type of End Mill used depends on the material you are cutting or machining and what the tool will be required to do. Some of the different End Mill styles that 2L manufactures are shown below.
Square End Mills are most typically used for milling, making shapes and holes, slotting, counterboring, and drilling. The End Mills have cutting teeth on the end face and the peripheral edge of the tool shank and can be used to cut a variety of materials in several directions.
Ballnose End Mills are typically used for 3D profiling, surfacing or for when a full radius is required at the bottom of the cut.
Single flute End Mills are the best choice for very soft, gummy, or stringy materials especially when used at higher spindle speeds. The cutting edges are sharper than other tools to create a clean cut with no or minimal burrs. The extra clearance created by the open flute design allows room for large chips to escape and helps prevent melting or burning the workpiece material. 2L’s single flute end mills are center cutting which means they can be used for plunging straight down into the workpiece (drilling).
Two flute End Mills are extremely versatile and are commonly used for plunge milling, slotting and pocketing routines. They can typically be operated at higher feedrates than single flute end mills but still provide for a large amount of chip clearance. Two flute end mills are available with differing sharpness on the cutting edges depending on what material is to be cut. They are available for cutting both soft materials such as plastic and aluminum and hard materials such as steel and titanium.
Three flute End Mills have less clearance space than single or two flute end mills but can be operated at higher feedrates. They are typically used for harder plastics and aluminum materials.
Four and six flute End Mills are primarily for cutting ferrous and other harder more difficult to machine materials.
