Probably a dumb question, but is any cordless drill that has 2 speed ranges - 1 higher speed, 1 lower-speed but higher torque - considered a Drill/Driver?? Dad wants a new "Drill/Driver" for Christmas and I'm trying to do the shopping. We've both had or currently have DeWalts but are getting a bit tired of their durability in the battery department. I know the Panasonics get consistently good reviews and the guy that put in our new furnace this summer had one and swore by it. He also had 3 other makes with him - all 4 chucked up with different stuff and said the Panasonic was his best one. I don't think he'd ever heard of those quick bit gizmos. Anyway he let me try it out and it had good balance and felt plenty powerful. The 2-speed Panasonic models I checked out online don't specifically say "Drill/Driver". Does the 2 speed ranges automatically make it a Drill/Driver vs. just a Drill ??
