I was very excited when I saw these drills coming out as I was hoping someone would make them. If you have a percussion tool, understand that this is always the tool you first use to tighten a screw or bolt. A drill simply cannot be compared. If you don't have an impact wrench then you don't know what you're missing and I highly recommend getting one. You will be amazed at the ease with which he turns screws. However, there are times when I want to pre-drill a hole for the screw I'm about to drive in, and in the past I've had to take the drill out so I can use one of my drill bits (a bit of a hassle). if it's not with you). Now I don't have to worry because I can use one of these bits right in my impact wrench and get the job done. Must have if you have an impact wrench.
