Sandro, Dewalt's low speed (which is where max torque is achieved) is only 450rpm while Milwaukee's is 500. This means that Dewault must "give-up" approx. 10% of its speed to achieve an approx. 1% increase in torque. The fact is (assuming the manufacturer's claimed numbers are correct) the Milwaukee's motor is more powerful. You are essentially correct though. I didn't realize any manufacture advertised more that 495in/lbs.
