How to choose a hammer drill for personal use? Nowadays, buying a branded drilling tool is not a problem, but how to choose the right hammer drill for yourself and your tasks? Explore the punch device and specifications.
What is the difference between a drill and a hammer drill and vice versa
The hammer drill is characterized by a longitudinal axial movement of the working part, similar to an impact drill. Therefore, hammer drills are confused with a heavy drill. In words, there is practically no difference, however, the hammer drill functions on the basis of pneumatics, and any impact (heavy) drill works thanks to mechanics.
Hence the difference in surface speed. Pneumatic drilling of holes in concrete, brick and stone walls reduces physical stress on the user. For any hammer drill, similar work is associated with great fatigue, and the hammer drilling mode wears out the internal components of the drill very quickly.
We come to the conclusion that the hammer drill should be larger and more massive than a drill with an impact function.
Energy and frequency of impacts
For a hammer drill, the impact function, measured in joules, is very important. The performance of the device, as well as the diameter of the hole to be machined, depends on the impact energy. For daily work with a hammer drill, this is one of the most important indicators.
It is essential that the hammer drill at the maximum will very quickly deplete its resource, and with the hammer drill they perform this work for a long time without wear, especially with the single-mode model.
It turns out that energy and frequency determine the level of performance. When choosing a perforator on your own, you need to evaluate the amount of work on chiselling, then, according to the specified characteristics of the impact frequency, calculate the approximate productivity.

Choosing the right drilling tool means making home repairs easier for a long time. How can you successfully choose a puncher in order not to overpay for the brand and get high-quality equipment?
Several decades ago, only powerful electric drills equipped with drills for metal and concrete were used in everyday life. A truly branded, specialized tool was sold only abroad; it was impossible to just go to a construction supermarket and choose a suitable device.

Perforators are widely used in construction work, both by professionals and by the apartment owners themselves. Often people do not distinguish a hammer drill from a conventional hammer drill, so the question of choosing a tool becomes rather vague. Before choosing a hammer drill, you need to understand a few basic points. One is the difference between a hammer drill and a drill. The second is the specificity of the work and the classification of the instrument. In this article we will tell you how to choose the right puncher for the job.
Tool set
You need to choose a hammer drill based on the complexity and nature of the work. At the same time, do not forget about the accessories for the tool. So, you need to take a set of drills in advance. Often when buying a unit, you can find that the basic set of drills is already in the package. This is quite enough for work of average complexity at home. However, for more complex work, especially when it comes to a professional tool, you will have to select components individually.
Drills are more expensive than drills. This is due to the fact that they are subject to increased requirements.
Spare brushes must be purchased if work is done daily. This is very important for craftsmen who have been using the tool for a long time.
For homework, one extra set of brushes is suitable. Often they are already in the package. Before choosing a hammer drill for your home, you need to see if there are brushes in the kit. This will save you money.
Rotary hammer types
Types Perforators have their own classification, therefore, you need to understand it.
Functional classification:
- Single-mode (drilling);
- Dual-mode (drill with impact);
- Three-mode (crushing function is added).
Weight classification:
- Lungs (2 to 4 kg);
- Medium (about 5 kg);
- Heavy (over 5 kg).
Thus, depending on the included functions, the widest range of work is available to rotary hammers:
- Drilling in wood, concrete and steel surfaces;
- Wrapping screws, bolts, screws;
- Chip;
- Rammer;
- Chopping work;
- Driving in rods;
- Making holes in ceilings.
How to choose the right hammer drill for your home
As a rule, starting the next apartment renovation with your own hands, you have to drill holes in the walls. This may be due to the need to hang a lamp or shelf in another place. It is good if the walls of the house are wooden or brick. But what if there is solid concrete all around?
You can’t do without a puncher. Why a hammer drill and not a hammer drill?
Drill device to drill holes. Drilling, not chiseling. For a hammer drill, the chiseling function is auxiliary, and is implemented very primitively. Two ratchets touching each other force the drill to make additional back and forth movements. The result is a swotting effect. Although the amplitude and energy of the impact are low. As a result, drilling a hole in a concrete wall requires significantly more effort than using a hammer drill. In addition, the impact ratchets are subject to heavy wear.
The hammer drill uses a pneumatic method of performing impact actions. The drill is not rigidly fixed like a drill in a hammer drill chuck. Slippage is prevented by special longitudinal grooves at the end of the drill. As a result, the impact energy is stronger, the drill does not turn and the hole is drilled much faster. In addition, the vibration transmitted to the hands due to the not so rigid attachment of the drill as the drills in the impact drill is much less. And it is not required to drill itself specially to press on the perforator during operation. Which rotary hammer is better? Asking how to choose a hammer drill, which one is better, many go on about their own greed. And they try to choose a professional tool of well-known brands like the Japanese Makita (Makita) or the German Bosch (Bosch). A professional tool is good, no doubt about it. But how justifiable will it be if you have to drill holes from time to time? There is a great chance that an expensive tool will lie in useless junk until the next repair.
Therefore, it is worth realistically evaluating the tasks to be solved with the help of this tool and reasonably approach the choice of a hammer drill for the home. In addition to the technical characteristics, which are discussed below, attention should be paid to the compactness of the instrument. Since many live in rather cramped apartments, there are places that simply cannot be crawled into with a large puncher. A compact, lightweight tool in this case will cope without difficulty. In addition, the low weight of a household or semi-professional rotary hammer will allow, if necessary, to work with one hand. It is also important if you need to hold on with the other hand while working.
How to choose a hammer drill?
The most common clamp for rock drills is the so-called Sds-plus. A lot of drills with such a limit switch are produced. So a hammer drill for simple household chores should be equipped with a cartridge for just such a drill mount. The drill is replaced by gentle pressure on the chuck. If an impact drill requires a lot of power for drilling, then a household rotary hammer does not need it in such quantities. Because he does not drill, but punches a hole. Therefore, for Sds-plus, a punch with a power of 400-800 W is quite enough. Especially on the power of the puncher, you should not get hung up. Since it is not power that is more important, but the impact energy. It has to do with power, of course. But additionally, each model takes into account the mass of the striker, the amplitude of the working stroke and the frequency of strikes. For a household tool, an impact energy of 1-2 J. Is quite enough. It is this that determines the maximum hole diameter. It is important to pay attention to such an indicator as the frequency of strikes. Together with the impact energy indicator, this characteristic determines the performance of the tool. Specific example. Rock drill characteristics: impact energy 1.2 J, power 450 W, impact frequency at idle speed up to 7500. The largest drilling diameter in concrete is 18 mm. A hole with a diameter of 6 mm and a depth of 80 mm is created in half a minute. than enough for the home.
When deciding which perforator is better, it is worth remembering that a professional tool is distinguished only by increased reliability and the possibility of a longer operating time. That is, in one sitting, a professional tool will be able to drill more holes than with a household one. Otherwise, they work the same way.

How to choose a hammer drill for home by operating mode
In simple units, the device is an elementary one mode and no additional features. In fact, such an apparatus is the same as a drill. Drills well in wood and metal surfaces.
complex devices are equipped with several functional modes:
- A dual-mode product assumes rotation and oscillatory movements during operation.
- The three-mode hammer drill is designed for additional impacts without spindle revolutions. Experts advise purchasing this particular unit for repairs in the house, because of its versatility. Drilling and chiseling are the main functions.
When choosing a hammer drill for work at home, be sure to take the device in hand. If the device is uncomfortable to hold, it slips out of your hands, does not fit in your palms, then the shape and design are not suitable for you. Try holding a different model in your hands.
It is good when the side handles can be dismantled in the device. This is useful if you have to make holes in a cramped place, for example, in a corner.
Home punch parameters
When buying a unit, ask the seller and look at the product passport to understand what characteristics the puncher has. What you need to pay attention to, experts give advice:
- The impact energy determines the diameter of the hole that the tool can make. If the impact energy is not more than 1-2 J, the power is low and the efficiency from the use of equipment is also small. The device drills a recess rather than punches. According to the experts, such a perforator wears out quickly and does not give the desired performance. By the way, too high an impact energy of up to 10 J is no better than a low one. Refractory inserts deteriorate in a short period of time. Therefore, for the home, choose a tool with an average impact energy of 3 to 4 J.
- The impact rate indicates the speed at which the rock drill can handle the required volume of work. This parameter also affects performance. In order not to get confused, give preference to proven brands. They care about the excellent quality of the unit and its durability.
- Spindle speed. The lower the power, the higher the rotation speed of the part. And what is this speed for? The shaft removes dust and debris from the work surface. The hammer drill with high shaft rotation speed is distinguished by a significant weight. The usability of the tool suffers from this. High-speed units quickly break down the spiral grooves created to remove the drill residue. The appliance is overheating. It is not surprising if the drill gets stuck in the wall while working.
- View of the chuck holding the drill. If you want to buy a hammer drill for household work, ask what method of fastening the drill is used in a particular brand of equipment. If the customer purchases a device up to 4 kg, the ideal mounting system is SDS-plus. The device is able to make a recess with a diameter of up to 3 cm, you should not demand more from it. But for household needs, it is quite suitable.
Rotary hammer functionality
- There is a drill depth limiter, which means that you can determine to what mark the drill has reached during operation.
- Adjusting the speed by shifting the lever. A useful tool when you need to switch from drill to drill and vice versa.
- Reverse rotation of the shaft is useful if the drill gets stuck in a concrete wall.
- The soft start and the overheating protection mechanism will help prevent damage to the device.
- Bringing to normal indicators of the shaft rotation frequency with fluctuations of forces with a load.
