linesman pliers guarantee you can cut anything.
A good cat stripper is worth its weight in gold.
As far as the corded/cordless.. I have used a dewalt 14.4 hammer drill for 5 years. The batteries are finnally showing their age, but I have 2. I always put one in the charger while I am working. Swap when needed. I drill a section, pull, drill a section, pull.
Only time I thought a corded drill was nice was when we had to do fiber through cieling passes of a manufacturing plant and punch through 10 walls with 1' plus of concrete. The power and speed was just more convenient. However, for residential stuff, I love my little dewalt.
