In brief: A cordless hammer drill driver combines a drill and screwdriver in one tool. Key buying considerations include voltage (10,8V for light-duty tasks and 18V for heavier work), torque, battery technology (Li-Ion) and a hammer function for masonry. Choose a battery platform that works with your other tools.

What is a cordless hammer drill driver?
A cordless hammer drill driver is a compact, powerful tool that combines two functions in one. Use it for precise screwdriving or switch on the hammer function to drill into hard materials.
Along with the rotary motion, the hammer function delivers rapid impacts that break up the material in front of the bit. This makes it easier to drill into masonry, concrete or natural stone.
For woodworking or drilling into metal, simply switch off the hammer function. The tool then works like a regular drill, making it a versatile choice for all your tool projects.
A screwdriver with a hammer drill function is an efficient choice for ambitious DIYers. It saves time and means you don't have to switch between tools.
Which voltage (volts) is right for me?
Voltage determines a tool's performance class and affects both power and runtime. The most common options are 10,8 volts and 18 volts.
A 10,8V tool is lightweight and easy to handle. It's a good choice for light assembly work, hanging pictures and putting together furniture. It's not designed for extended drilling into hard masonry.
An 18V cordless hammer drill driver is a popular choice for home and garden projects. It has enough power for putting up shelves, installing garden fences and drilling into exterior walls. Most power tools in this category use 18V batteries.
Important note
Check compatibility carefully. Choose tools from a manufacturer's battery platform so you can use the same batteries and chargers with different tools. Over time, this can save money and storage space in your workshop.
Choosing the right battery technology
Modern cordless hammer drill drivers use lithium-ion batteries (Li-Ion). Li-Ion batteries are lighter and more powerful than nickel-cadmium batteries, and they have no memory effect.
Battery capacity is measured in ampere-hours (Ah). At the same voltage, a 4,0 Ah battery lasts longer than a 2,0 Ah battery. Higher capacity is useful for longer jobs when there's no power outlet nearby.
Which technical specifications should I look for?
Besides voltage, other specifications affect a tool's performance. Knowing what they mean can help you choose the right model.
Maximum torque, measured in Newton metres (Nm), indicates turning force. A high torque of 50 Nm or more can drive thick screws into hardwood. For simpler jobs, 30-40 Nm is usually enough.
Impact rate, measured in impacts per minute (bpm), indicates how fast the hammer function works. Rates between 20.000 and 30.000 bpm can speed up drilling in hard concrete. A medium impact rate is usually enough for brick.
Many people underestimate the importance of no-load speed. A higher no-load speed doesn't automatically mean more power at the drill bit, but it can make drilling in soft materials cleaner and faster.
Chuck type matters in everyday use. A keyless chuck is convenient, while a keyed chuck can provide a firmer grip on larger drill bits. Choose the type that suits your needs.
Pro tip
Check how the tool feels in your hand. A well-balanced cordless hammer drill driver has its center of gravity close to the handle. That can reduce fatigue during longer jobs.
Two-speed gearbox: A clear advantage
High-quality models have a two-speed gearbox. First gear gives you high torque at low speed, making it ideal for driving large screws.
Second gear offers higher speed and lower torque. It's ideal for drilling smaller holes or working with softer materials. This feature makes your hand tool more versatile.
What accessories do I need?
The right accessories make your work more efficient and safer. Start with a basic set and add to it as needed.
Drill bits: Use the right bit for each material: carbide-tipped masonry bits for masonry, HSS metal bits for steel and aluminum, and wood bits with a center point for wood.
Bits: A selection of bits for Phillips (PH), slotted (SL) and Torx (TX) screws is essential. Quality bits are less likely to break and help protect screw heads. Browse our sockets and tool attachments.
Additional advice
Buy a second battery so you can keep working while the first one charges. This is especially handy for large garden projects or construction work.
Sturdy storage helps protect your investment. A tool case or system box keeps your tool and accessories clean and close at hand. Browse our tool cases for suitable options.
Workplace safety comes first
Always wear safety glasses. Drilling dust and small splinters can injure your eyes. Wear hearing protection during noisy jobs or when working in enclosed spaces.
Before drilling into walls, check for hidden cables and pipes with a cable and metal detector. This helps prevent dangerous short circuits and damage.
How do I maintain my tool?
Regular maintenance can extend the service life of your cordless hammer drill driver. A few simple steps make a big difference.
After each use, wipe the housing with a dry, soft cloth and remove dust from the ventilation slots to help prevent overheating.
Charge Li-Ion batteries at room temperature. Extreme cold or heat can damage the cells. Avoid storing spare batteries fully discharged for extended periods.
Occasionally lubricate the keyless chuck with a suitable grease. This helps it operate smoothly and prevents it from seizing. Find more maintenance products in tool accessories.

Frequently Asked Questions
- What’s the difference between a cordless drill driver and a cordless hammer drill driver?
- A standard cordless drill driver is designed for rotary drilling in wood and metal, as well as driving screws. A cordless hammer drill driver also has a hammer function that delivers rotary impacts, making it suitable for drilling into masonry, concrete, or stone.
- What voltage do I need for a cordless hammer drill driver?
- For light tasks such as assembling furniture or drilling into thin walls, 10,8V or 12V is sufficient. For general DIY projects around the home and garden, 18V is the standard choice. It provides enough power for most masonry drilling and more demanding screwdriving tasks.
- How long does the battery in a cordless hammer drill driver last?
- Runtime depends on the battery capacity (Ah), the task, and the voltage. An 18V battery with 4,0 Ah lasts around 30-60 minutes under medium load. Lithium-ion technology (Li-Ion) is key because it offers a long service life and no memory effect.
- Can I drill into reinforced concrete with a cordless hammer drill driver?
- Yes, with a powerful 18V tool and a high-quality masonry bit designed for a rotary hammer. For frequent or professional work on reinforced concrete, however, a dedicated rotary hammer is the better choice because it delivers a hammering action without rotation.
- What does torque (Nm) mean on a cordless hammer drill driver?
- Torque measures the force with which the tool rotates. High torque (e.g. 50-80 Nm) is important for driving in and removing long or thick screws. Many models offer electronic torque control to help prevent damage to the material.
