Mine has 450 rpm and regular setting. But this gun has some serious torque. Heavy but worth it.
I did get 3rd battery! And after I bought my 12 v lantern last year and it has 12v/18v charger. so its a score I can keep one charger at home and one at work.
I am waiting for a sale on 18v 3/8 impact too! And my tool bill to gets back down to a reasonable amount,,,,!
