Impacts per Minute (IPM) Grade: Below Average

The DeWalt DC825KA has a top IPM of 2700 IPM. The average top IPM of 18 volt cordless impact drivers is 3016 IPM. An impact driver delivers blows in a rotational way as opposed to a hammer drill which delivers blows into the work. The higher the IPM of a cordless impact driver the faster a screw or bolt will be installed or removed. If you are looking for a cordless impact driver with more impacts per minute, check out my review of the Makita BTD144 18 Volt Impact Driver. It is rated at 3400 IPM.

Power Grade: Below Average

The DeWalt DC825KA has a power rating of 1330 in/lbs. The average power rating of a 18 volt cordless impact driver is 1369 in/lbs. The power of a cordless impact driver is measured by torque (inch-pounds). Torque is the measurement of the twisting force the drill applies when started.
