Try a larger cut off wheel.. should take about 3-4 seconds. Or go bigger and use a sawzall with metal cutting blade.
Try these for your dremel Cut Off Wheels (http://www.amazon.com/exec/obidos/tg/detail/-/B00004UDH9/qid=1085357794/sr=8-2/ref=sr_8_xs_ap_i2_xgl60/002-1396271-9841632?v=glance&s=home-garden&n=507846)
