Straight Flute End Mills

End mills with straight flutes are single ended, 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 helical general purpose end mills.  They come in square and ball nose end geometries with two or four flute configurations.  They come as solid carbide or PVD AlTiN coated.
