Direct Comparison of Milwaukee 2401-22, 2402-22 and 2406-22


This is the most important aspect of any screwdriver kit. 2401-22 has the strongest punch at 375-inch lbs. This makes it the top choice if you need a small drill to handle the tough projects.  2406-22 comes in second with 275lbs, strong enough to handle most regular pesky screws and nuts at home or on-site which is why it is more of a universal driver choice for both light projects and tough jobs. 2401-22 is a light task driver with a higher focus on precision and a clean finish rather than the punch. It is your tool of choice for light delicate tasks as well as jobs that require a high level of accuracy.


All these screwdrivers have multiple speeds matched to the task each tool is designed to handle. 2402-22 has the highest speeds at 0-450/0-1700RPM meaning it can drive larger screws fast as well as drill fast. Its high speed, however, undermines precision because of a weaker grip which is why it is not recommended for small delicate wood and plastic surfaces. This advantage goes to 2406-22 which has speeds of 0-400/0-1500 rpm. The speed is high enough but the regulated 275lb torque keeps you in full control. 2401-22 also has variable speeds which have a very small difference. The range is 0-400/0-500rpm which is good enough for drilling small holes and driving small screws without chipping or overdrive.


Milwaukee package batteries are a great match to torque and speed which guarantees enough juice for a whole day`s work as long as you have your back up. 2402-22 has the best battery-package coming with two 2AH batteries. Our tests confirmed a battery life of 3 to 4 hours under continuous use. 2406-22 AND 2401-22 both come with 1.5AH batteries. 2406-22 had a shorter battery life than the rest by up to 30 minutes. We highly recommend getting an extra 2AH package for all screwdriver kits if you don’t have a direct power source at your site of work.

Final Note

12V impact drivers are a lifesaver whenever fastening and unfastening screws and lug nuts are involved.
