The kit bundled in the tough, CP branded carry case includes the CP8548 itself, two 20V lithium-ion batteries with 4Ah of capacity, and the CP20CHK charger.

We'll come back to the batteries and their capabilities later.

The CP8548 weighs in at 2.4kg which is about average for a top-end combi drill and it certainly feels like a flagship cordless product in the hand. What's interesting is the slightly squared off shape to the motor which transitions into the mode selector switch.

This is positioned at each side of the drill, making it very easy to move between modes when you're wearing gloves, but it isn't sensitive enough to be accidentally bumped into the wrong mode. Moving forward from the mode selector you come to the 24 stage torque selector, giving you huge control over your screwdriving applications.

The maximum torque available is a whopping 82Nm, and in screwdriver mode you'll be able to deal with screws up to 8mm.

When in hammer mode, the true grunt and power of the CP8548 is more than evident, delivering 25,600 blows per minute in 2nd gear, with the gentler 1st gear offering you 7,200bmp. This gives you the ability to drill 16mm into masonry  and 13mm into steel.
When you're drilling wood via the 24 torque selectors, the drill offers you up to 450rpm in first gear and 1600rpm in gear 2.

Chicago Pneumatic 20V Lithium-Ion Batteries

The 20v label on the battery is an interesting one, and we see Milwaukee doing something similar. However, these batteries are essentially 18v packs, but offer you a maximum of 20v when fully charged. But let's face it: the 20 volt lable does look pretty cool, right?
