Unibit is Irwin's trademark for step bits. :-)

Another tool thats really handy to have around when drilling holes in metal
is a deburring tool.  Look at General Tools #482.  Note that there are two
different blades for it, one for aluminum and one for steel.  These will
quickly take that lip off a hole you just drilled and can also be used to
remove the lip along a piece of metal thats been sheared with a slightly
dull shear.
