Actually, it's not a bad question. While you can attach a driver bit to any drill, if the drill doesn't have some sort of brake, you run the risk of driving the screws too far into some materials (in my experience, the torque settings are only marginally useful). For example, I've used my Milwaukee 1/2" corded drill to drive big screws into 2x6's but the drill continues to spin after you release the trigger. So you have to learn to release the trigger 1/2 second early or pull the drill away while it' still spinning . If you don't, the momentum will either drive the screw down below the surface, or the screw will stop and the rest of the drill will torque around. My el-cheapo Harbor Freight cordless drill is the same way. On the other hand, my new Craftsman drill/driver stops immediately upon releasing the trigger.
