If it takes a 1/4" shank you should be ok.  My die grinder is an
angle grinder (head 90deg to the body).  I purchased a 1/4" shank
arbor with a 3/8" and 1/4" head.  I buy 3"x 1/8" or 1/16" thick
cutting disks and put them on the arbor.  It works pretty good.
As I said before, better than the 4" grinder.

The one you describe sounds like the electric one my dad has.  He
also uses the 1/4" arbor and the cutting disks on his.  His is an
inline one.  I don't think I've seen and angle version of it.

Someone suggested, using the money for the electric cut off tool and
putting it towards a compressor.  That's up to you.  However, one
thing I don't like about my dad's electric (oversized dremel) tool,
is it is bigger, and heavier than the air driven die grinder.  Also
when it catches, the inerta of the motor will really cause the tool
to jump, whereas the air tool simply stalls.  Also when you turn off
the electric tool, it keeps running for a while (again the inerta).
The air tool stops almost immediately.
