A cordless hammer drill is a power tool great for drilling holes in walls: stone, brick and concrete when you don't have access to mains power. It needs to be used with specific type of drill bits, called masonry bits. It has a hammer mechanism inside the drill which will deliver concussive blows behind the masonry bit to assist in drilling into hard material like brick and masonry.
Smaller hammer drills usually have a couple of settings allowing you to turn off the mechanism and just use the normal drill in wood, metal or plastic. Bigger hammer drills usually only have one setting: hammering but it makes them more powerful. But for proper power, rotary hammer drills are the best.
Is this the the correct drill for your project?

***BODY ONLY*****
THIS IS THE TOOL ONLY. YOU WILL NEED TO BORROW A CHARGER AND BATTERY SEPARATELY FOR THIS TOOL UNLESS YOU HAVE COMPATIBLE 18V DEWALT EQUIPMENT AT HOME. A LIST OF COMPATIBLE CHARGERS AND BATTERIES IS AT THE BOTTOM OF THIS DESCRIPTION.
ABOUT THIS TOOL
- hammer drill function
- 15 stage adjustable torque for driving/extracting screws
- 18V DeWalt XR battery system
- Compatible with all DeWalt batteries and chargers on the system individually
WHAT IT DOES
This tool has three settings. The regular drill setting, signified by the picture of a drill bit, for drilling through wood, metal and plastic, the hammer drill setting (picture of a hammer) for masonry of all kinds, and the driver setting (numbers 1-15). The driver setting is what you use to drive screws in, or indeed take them out. The number corresponds to the amount of torque (15 is the highest) on each setting. By making this adjustable, you will be able to put screws into your project using the minimum force, and thus reducing the risk of threading the head of the screw.

HOW TO USE IT
Fit the auxiliary handle to steady the drill and protect you if the drill jams.This is important when drilling large diameter holes especially into masonry, and into wood using a flat bit, or hole saw. Here is a video about the safe use of the auxiliary handle: https://youtu.be/oGphjIuyDg4?t=10
For drilling holes, use a higher speed. Consider using a centre punch drilling a smaller pilot hole first to guide the hammer drill. Back-out of the drill hole frequently while drilling to allow the drilled material to be removed from the hole and avoid overheating and bluntening the drill bit.
For driving screws, turn off the hammer setting, use a slow speed and set the torque clutch to a low number to start, increasing gradually if necessary.
