Standard cut is a general purpose tool designed for cast iron, steel, some copper and brass, and other ferrous materials.  It will give good material removal and good work piece finishes 

 

DOUBLE CUT
Double Cut allows for rapid stock removal in harder materials.  The addition of the left hand flutes reduces the pulling action, allowing better operator control.  It reduces the size of the chips and can be used at slower than normal speeds.
