End Mills

An end mill is a type of cutting tool that is used in milling applications.
They have cutting edges on the end and sides of the shank enabling them to cut in all directions.
The purpose of an end mill
The end mill remove material by their movement within the milling machine or from the cutter’s shape.
The number of flutes (spirals on the end mill) give different results
• 2 flute allows maximum space for chip ejection and is used for general milling operations
• 3 flute is an excellent choice for slotting, it has a larger cross section and is used in general milling operations
• 4, 5, 6 and 8 flute can improve the surface finish if the feed rate remains the same. A greater number of flutes reduces chip load and produces a much finer finish
End cut types
• Centre cutting end mills have one or more cutting edges at the tip to allow the user to plunge, drill or ramp into a cut.
• Non-Centre cutting end mills have peripheral teeth that allow the user to side cut or contour an external surface.

Shank Types
• End mills with a plain shank are used with a collet style holder and are the most common shank type
• End mills with a Weldon shank have one or two flats with set screws in the holder that tighten on the flanks of flats to hold the mill to prevent it from rotating

Typical applications
End mills are used for profiling milling, face milling, tracer milling, semi-finishing and finishing.
