How to choose a high-quality and inexpensive punch for home

What to look for when choosing a perforator

The most functional models meet all user requirements. Picking up a device for homeworktake into account the following indicators:

1. Impact energy. In light models, this figure reaches 1-2 J, in more serious units, the impact energy is from 8 to 15 J.
2. Beat frequency. This criterion determines how quickly the model will break through the hole.Often, eminent manufacturers skillfully combine productive energy and frequency of impacts, resulting in an excellent functional model of a rotary hammer for home and work.
3. Power. Compared to a drill, a hammer drill is not equipped with high power and speed, as it is designed for drilling. The power of the devices varies from 400 W to 1.2 kW.
4. Rotation frequency. According to the product class, the rotational speed ranges from 600 to 1500 rpm.
5. Cartridge type. Today there are three ways to mount the drill: SDS-Plus, SDS-Max, SDS-Top. The first option is suitable for domestic needs, it is able to make holes up to 3 cm; the second option is optimal for large heavy punchers - a hole is obtained with a diameter of up to 5.2 cm. The SDS-Top option is widely used by Bosch, it can make holes with a diameter of 1.6 to 2.5 cm.
6. Operating modes. An inexpensive hammer drill will be single-mode, in its abilities there is the ability to drill holes like a drill. A dual-mode device can not only rotate, but perform oscillatory maneuvers. The tri-mode punch is capable of delivering punches without spinning.

When choosing the best perforator, it is worth considering its shape - the device must be ergonomic. Models can be narrow and long, as well as straight or L-shaped.

The best inexpensive hammer drills for the home: a budget of up to 7,000 rubles

For the home, it is not at all necessary to purchase powerful rotary hammers with rich technical characteristics. Having spent a round sum, you can purchase a tool whose capabilities will never be realized.

Most users need a hammer drill to drill holes for dowels and anchors, drill brick or concrete, make holes for a socket.Less commonly, a hammer drill is used to dismantle piers, ditch for wiring and remove concrete sags.

Today, there are many models on sale, including well-known brands that you can really buy by spending no more than 7,000 rubles (or even much less). For the home, it is quite enough to take models with a power of no more than 850 watts. The maximum impact energy of such "home" tools is on average 2.7 - 3.2 J. Anything more than 12 J is already professional tools, the price of which is $ 500 and more.

1 Makita HR5211C

The Japanese, as always, are on top. The Makita HR5211C puncher cannot boast the best numbers in all criteria, but it costs an order of magnitude cheaper than the silver medalist in our rating. The impact energy is 19.7 J, which is partly offset by the higher impact frequency. Judging by the reviews, the model does an excellent job with any materials: from brick to reinforced concrete.

The main thing is that the user can cope with the punch itself, because its mass is almost 10.8 kg. Fortunately, a D-shaped handle is provided on the body, which greatly simplifies holding the tool. It is impossible not to note the presence of a carbon brush wear indicator - a very useful feature.

Advantages: Very high power; excellent reliability (withstands about 5 years at very intense loads); anti-vibration system; soft start of the engine; no shock without load; Comes with a package of lubricant.

Attention! The above information is not a buying guide. For any advice, you should contact the experts!

Safety clutch

To prevent tool breakage and damage to the person using the tool, a safety clutch is used when the drill is jammed. There are two types of clutches: friction and spring-cam.

Friction clutches consist of discs pressed against each other and transmitting rotation. At the moment of jamming, the discs slip, disconnecting the shaft from the chuck.

Spring-cam consist of two coupling halves. The half-couplings having teeth are pressed against each other by a spring. When the drill is jammed, the resistance begins to exceed the force of the spring, the teeth will begin to slip, and a characteristic crack will be heard. It is believed that spring-cam is more reliable than friction. Their downside is tooth wear.

Electric part of the puncher

As a rule, a collector type engine is used. Also, on most models, the so-called reverse circuit is used (it is possible to use it as a screwdriver).

Perforator body

Most often, the body is made of several materials. These are metal (aluminum alloys), hard plastic, soft plastic.

Anti vibration system

Vibration protection systems are divided into active and passive.

Active systems (AVS) are installed on powerful models. This is a shock-absorbing device, a counterweight with a spring that absorbs recoil.

The passive system is a set of all possible rubberized pads, handles, which, in addition to anti-vibration properties, allow hands not to slip.

So, having considered the technical parameters, I would like to touch on one more important parameter: the cost of the tool.

The cost of a household tool starts from $50 to $250.The cost of a professional tool reaches $ 1,000.

Nevertheless, you should not buy the cheapest one, even if you do not have plans for a global restructuring of the apartment. Most likely, it will not serve you for a long time, and in case of intensive use it will not be able to help you at all. Take a closer look at the puncher in the middle price category.

For almost all work that may arise on the repair of an apartment, a puncher from 1000 watts up to 1500 watts with a horizontal engine.

This will allow you to work in narrow places, with a shock energy of 2-3.5 J. A nice bonus is the ability to have three modes of operation and reverse.

The cordless hammer drill is currently gaining particular popularity, the advantages of which include high mobility. No need to drag wires, it is possible to work in places where there is no power supply.

The disadvantages include the fact that the battery lasts for about 3 hours of operation, then it needs to be charged. Another disadvantage is that the batteries do not last forever and the approximate service life is from one to two years.

How to use a perforator correctly

Tool durability and ease of use depend on many factors, but there are universal tips for all cases.

• • The technical parameters of the tool must meet the loads and duration of operation. Small household work can be done with household hammers, for construction activities you need a professional tool.
  • During work, you should take a comfortable and safe position: the support of the legs should be reliable, the flooring should be stable. The worker must have enough free space for movement, not be distracted by extraneous factors, etc.
  • It is never necessary to dismantle the special auxiliary handle. This not only makes work easier and safer, but also increases productivity and quality.
  • The workplace should be in order, all unnecessary items, tools and large construction debris removed.
  • During operation, only "native" lubricants, cartridges, compatible drills, chisels and other tools should be used.
  • Before starting work, it is necessary to check the technical serviceability, if necessary, perform a set of routine technical work.
  • It is forbidden to overheat the engine, a large amount of work should be done intermittently. You need to work only with sharp tools, blunt ones significantly increase the load on all nodes, cause rapid fatigue, and reduce labor productivity.

Interesting to know! Overheating stator and rotor windings they cool much faster and are safer when idling. Do not just turn off the tool, it worsens the situation. A running engine effectively removes heat with a special impeller.

• It is strongly not recommended to apply large bending forces. The tool is not designed for such work; when critical loads are reached, all rubbing pairs quickly wear out. The axes of long fixtures are often deformed, and it is forbidden to work with them in the future.
• After working in conditions of increased dustiness, it is recommended to make a careful inspection of the condition of the brushes and the collector, clean the stator and rotor windings.

All punchers have several modes, they must be used correctly:

1. only blow - for work in the jackhammer mode;
2. only rotation - for working with diamond crowns or ordinary drills;
3. rotation and impact - for working with drills with victorious soldering, holes are made in hard materials.

Incorrect mode selection damages the tool, sometimes it has to be thrown away. In addition, the work becomes much more complicated, their quality deteriorates, the punch can completely fail.

Important! To minimize the risk of injury, it is mandatory to use personal protective equipment.

Important additional options when choosing an electrical appliance

"Vario-Lock" is a locking system for fastening drills, bits, a peak in a certain position, which prevents the tool from turning during the chiselling process.
Ergonomics - horizontal models are longer, they are easier to work in narrow spaces, but the center of gravity is shifted to the handle. Vertical tools are more compact and balanced, work longer without interruption, but they are more expensive. The presence of anti-slip pads, an additional handle, a long power cord greatly facilitate the use of the mechanism

It is important to consider individual convenience when choosing a model.
Reverse - the function of switching to the opposite movement of the drill, for example, when wedging in the wall.
The start stop button is convenient for long, monotonous work.
Drilling depth limiter - a special fixed rod helps to estimate the length of the hole made;
The dust removal system in the form of a corrugated hood collects litter inside, as a result of which small particles do not injure the eyes and respiratory tract. Models with a vacuum cleaner are useful when drilling holes in the ceiling.
Case and accessories - manufacturers often supplement a convenient suitcase with a minimum set of equipment, a cartridge, and lubricants.

Buy power tools from the best manufacturers in specialized large stores. In retail departments, you can carefully examine the model you like, try it on your hand, and feel how comfortable it will be to work with it for a long time.

There are foreign and Russian manufacturers on the market, who have proven themselves to be of excellent quality and inexpensive options for rotary hammers, in comparison with foreign counterparts.

Our review of the mechanisms of different price categories will help you navigate when buying the right and optimal model of power tools.

Optimal type of perforator

At the first stage of selection, one should decide on the basic belonging of the instrument to one or another category according to the main classifications. In particular, the design and power supply system should be determined. As for the structural device, there are horizontal and vertical perforators for the home. Which to choose? Models of the first type with a horizontal engine are more like drills.In essence, this is an electric drill, but supplemented with an impact function - a kind of jackhammer. This option is easy to handle and a good choice for a beginner, but it is unlikely to be able to perform complex operations for the destruction of concrete and brick structures in a large volume. The vertical configuration is distinguished by power and a more efficient cooling system - accordingly, the device will be able to work at high loads.

Now you can go to the power system. Network and battery models are fundamentally separated. As the reviews show, the first ones have a greater power reserve, while maintaining a compact body and lightness. The presence of a battery pack makes the structure heavier and reduces maneuverability

Although, the addition of weight in the case of a perforator can also be a plus, since the stabilizing effect increases, which is important during heavy work. How to choose a rotary hammer by type of battery? It is worth focusing on lithium-ion cells (Li-Ion)

They do not have the effect of self-discharge, with a small size they have a high energy potential and are undemanding in maintenance. But, one should also take into account the capriciousness of the Li-Ion block when working at low temperatures and the price factor - compared to other models, rotary hammers with such power supply are 10-15% more expensive.

5. Types of perforators by power

The impact force of a perforator depends directly on the power of its engine. This indicator determines the force with which the drill or drill will enter the required material. The higher this indicator, the higher the speed of the work performed.

• A light tool has a weight of up to 4 kg, the impact force of such a perforator reaches a maximum of 3 J, the power is up to 0.8 kW.Such equipment is used exclusively for domestic purposes and only for drilling not too hard materials.
• The average device has a weight of up to 8 kg, the impact force reaches 9 J, and the power is in the range of 0.8 - 0.9 kW. They are used to make holes in reinforced structures or in materials with a high degree of hardness.
• Heavy perforators have a weight of more than 8 kg, their impact force reaches more than 17 kJ, and the power is more than 1.2 kW. Such a tool is used in professional activities and has almost unlimited possibilities.

Before making the final choice, it is necessary to understand that not only the force, but also the impact frequency depends on the performance of the tool and the speed of work. Even if the impact force is high, but its frequency is small, you will move slowly and waste a lot of time. The optimal frequency of impacts for a household perforator lies in the range of 3-4 thousand beats / min, and for professional ones it should reach an indicator of approximately 5000 thousand beats / min.
