PROs: It's a monster! It will gnaw through wood and even nails (although I had no intention of gnawing nails). I built a new house and ran my own data, security, and coax using 1 1/4" Carlon PVC flexible tubing (blue "smurf tubing") through 2x4 double and triple joists. Although the drill bit is a little boring, it's still able to drill more holes. CONS: YOU NEED THE RIGHT DRILL - it should be strong enough. I have a 26v battery powered Dewalt and a 6 amp cord handyman that can't handle the job (underpowered). Solution? I bought the biggest amp drill I could find 10 amp corded Dewalt. Unfortunately due to the high current requirements I also had to buy 150ft of 12AWG wire per the drill instructions (smaller wire would result in reduced performance and the risk of overheating.) the distance you walk.When the house was built there was only one outlet and for me it was over 100 feet.However, for shorter distances I would still recommend 12AWG- Go with cables just to be on the safe side. But BEWARE, if you don't have enough strength to drive this bit, it won't work for you.
