4mm/6mm Shank 2 Flute Straight End Mill
Two flute square end mills with straight flutes are single ended, have two cuttting edges, and have a zero degree helix. They are used to mill plastics, composites of epoxy and glass, and are also used for special profile milling applications. The straight flute minimizes the fraying of the edges and provides better surface finishes than general purpose end mills.

2-Flute Straight Carbide End Mill
End mills with two flutes are most commonly used for creating grooves or slots. This type of mill is also known as a plunge mill, because it can drive vertically into the workpiece. The cutting end of the bit has two blades, of unequal lengths. One goes directly across the middle, allowing the end mill to plunge straight into the workpiece beneath it. A 2-flute mill cannot be used for the same applications a 4-flute mill.
Traditionally, end mills came in either a 2 flute or 4 flute option. The widely accepted rule of thumb was to use 2 flutes for machining aluminum and non-ferrous materials, and 4 flutes for machining steel and harder alloys. As aluminum and non-ferrous alloys are typically much softer than steels, a tool’s strength is less of a concern, a tool can be fed faster, and larger material removal rates (MRR) is facilitated by the large flute valleys of 2 flute tools. Ferrous materials are typically much harder, and require the strength of a larger core. Feed rates are slower, resulting in smaller chips, and allowing for the smaller flute valleys of a larger core tool. This also allows for more flutes to fit on the tool, which in turn increases productivity.
Recently, with more advanced machines and toolpaths, higher flute count tools have become the norm in manufacturing. Non-ferrous tooling has become largely centered on 3 flute tools, allowing greater productivity while still allowing proper chip evacuation. Ferrous tooling has taken a step further and progressed not only to 5 and 6 flutes, but up to 7 flutes and more in some cases. With a wider range of hardness, sometimes at the very top of the Rockwell hardness scale, many more flutes have allowed longer tool life, less tool wear, stronger tools, and less deflection. All of this results in more specialized tools for more specific materials. The end result is higher MRR and increased productivity.
