About this impact driver
This is a cordless impact driver from Milwaukee's M4 line, running on a 4 V lithium-ion battery and taking a 1/4 in. hex drive. The kit includes two batteries, so you can keep one charged while the other is in use. It suits shoppers who already own, or plan to build around, the M4 battery platform, since the battery is the part that must match across tools. Check the drive size of 1/4 in. against the bits you already have, and note that the kit configuration includes the batteries listed.
