For home repairs, remodeling, and other renovations, a hammer drill can easily drill through hard materials like brick, concrete, and stone. This type of power tool is similar to a regular drill but works like a hammer drill, making it especially useful for do-it-yourselfers.
The impact drill is suitable for heavy work such as drilling or breaking concrete or bricks.

What should you look for when buying a hammer drill?
The best drill for concrete walls
Drills are used where drills and percussion drills are no longer powerful enough. Drills should be used especially for drilling in concrete and hard stone (natural stone, masonry). In addition to drilling, chiseling is also possible. Therefore, hammer drills with chisels are often used for demolition work. They can be used to quickly and easily punch holes in walls or tear down entire walls.
When buying should pay attention to the following:
- The power consumption of a 700-watt hammer drill is an important limit for achieving good performance in all areas. Significantly less powerful devices are only suitable for occasional work and heat up quickly in continuous operation. Power above 1000 watts is not even necessary for continuous operation in normal household use.
- The number of strokes per minute of a hammer drill should not be too high, otherwise, the individual strokes will have too little power. But it should also not be too low, otherwise, the work will take too much time. The drill should deliver 4,000 to 4,500 blows per minute.
- The maximum impact force is especially important because it shows how much force a single blow has. The impact force should be at least 2 J for the hammer drill to work well.
- When it comes to the gearbox of a percussion drill, you can distinguish between a 2-speed gearbox and a 1-speed gearbox. Models with a 2-speed gearbox may have more power consumption. This can be an advantage, especially if you want to drill accurately. The percussion drill test shows you: In first gear, you can start drilling relatively slowly and aim as accurately as possible. When you shift into second gear, you can drill relatively quickly.
- Drill guns that are adequate for basic home use require a drill thickness of only 0.87inches in concrete and 0.51inches in steel. However, they must have this drill strength to be used for all types of activities.
- Weight plays a big role in a drill. Pay attention to the weight of different models, especially for continuous use. It ranges from 4lb to 8lb.
What must be observed when using a hammer drill?
As with all technical equipment, some rules must be observed when using it.
- It is advisable to wear suitable protective clothing. Clothing must cover all parts of the body. Additionally, protective goggles and gloves should be worn.
- Since the hammer drill makes relatively loud noises, you should not use the device during downtime.
- Others should stay 2-3 meters away from the drill to avoid being hit by flying stones.
- Do not use the rotary hammers if you are taking medication that can alter your perception.
- Use only truly appropriate accessories. A pointed chisel and various drill bits are usually included in the starter set. However, when buying additional accessories, make sure that they are suitable for your own quick-change chuck.

How does a hammer drill work?
The impact drill combines the phases of drilling and punching. This facilitates the drilling of holes in mineral material (e.g. brick or concrete). An additional stroke of over 4000 strokes per minute removes the material. The rotary motion allows the cutting edge of the drill to penetrate the stone and push the dust outward. These devices are mainly used manually and without mechanical aids.
Questions about the hammer drills for home projects
Which grease is used for hammer drills?
Modern hammer drills all have an SDS drill chuck, but hammer drills with SDS-Plus are also popular. Of course, you need special drill bits for this drill chuck. In addition to the drill bits, however, grease is also needed so that the drilling and percussion function does not damage the drill chuck or the drill bit gets stuck completely. For this reason, the plug connection should always be well greased and free of dust and dirt. Grease is available from all manufacturers, but we recommend the grease from Makita, as it produces the best results. For proper oiling, it is also often worth buying a proper grease gun.
Which drill a bit for the hammer drill?
There are different quick-action chucks for the rotary hammers. Most manufacturers use the SDS-plus system. Excellent drills in this area are available from Makita. Large machines may have the SDS-max system installed. The drills are significantly more expensive and have a thicker shaft. However, a set with the most important drills, can not be purchased for less than 75. The cordless hammers from Bosch usually have the SDS-quick system. Special and smaller drill bits are needed here. The hammer drill comparison has shown that good drill bits here are from Connex.
How many joules of power does a hammer drill need?
It is always difficult to give concrete values here. As a rule, the power should be appropriate for the construction project. In a hammer drill test, you will realize that 2 joules should be available so that the hammer drill can be used for all kinds of work.
Can a hammer drill also be rented?
Especially in the private sector, a hammer drill is used very rarely. So that an expensive purchase does not have to be made immediately, hammer drills can also be rented in hardware stores. Often, all that is required is a deposit and a small fee to rent the tool for a certain period of time. Depending on the model and manufacturer, the tool is handed over in a suitable case to have a reasonable transport option.
Conclusion about the hammer drills
When it comes to construction or any other construction-related project, you need to have access to a hammer drill to handle projects in a more advanced mode. Concrete and other types of extremely hard surfaces can be very difficult to handle when trying to remove them to make way for a new building or construction area in general.
