Best rock drills from Metabo in 2020

One of the best manufacturers of rock drills is the German company Metabo. It began its existence in the twenties of the last century, and from that moment the organization's conveyor began to produce a wide variety of electric, pneumatic and cutting tools. The list of products created by the company includes a wide range of rotary hammers with various capabilities. That is why absolutely every customer can choose the model that suits them, and a selection of the best Metabo hammer drills in 2020 will help to understand the variety.

The main advantages of rock drills

The most popular Metabo tools are electric models, characterized not only by the possibility of drilling, but also by punching holes in metal, wood and stone surfaces. The main distinguishing feature of these instruments is considered to be an innovative impact mechanism that provides sufficient impact force to interact with hard and rigid surfaces. In addition, the drills of the German company have a lot of advantages.

  • RPM control. The tool is equipped with a special sensor that provides a tight control of the speed. This function makes it possible to process various materials at the selected speed. The result is a high-quality finished surface, which is produced using specially set revolutions.
  • Reverse. It ensures safe extraction of cutting tool teeth without various defects on the work surface.
  • Disconnection mechanism. A specially installed clutch in the mechanism serves as a guarantee of safe operation. If an emergency occurs during operation, the clutch disengages the clutch and the engine stops automatically.
  • Mechanism shutdown lock. This function serves for convenient operation when the user's hands are tired.
  • The presence of comfortable handles. A very useful additional unit that provides comfort when working with the tool.

Rotary hammer selection criteria

Before deciding to buy a percussion instrument, consider the following criteria to ensure maximum productivity during your workflow.

  • Variety of options. When buying a percussion instrument from Metabo, you should pay attention to all the nuances of the model, since further use depends on it.The manufacturer provides a huge selection of rock drills equipped with various modes of material processing and other characteristics. Considering the possible weight of the tool, there are divisions of light, medium and heavy devices.
  • Impact energy. The most important parameter that you should pay attention to when buying is impact energy, measured in joules. The lightest models of the German company's rock drills are characterized by low impact energy (2 J), while the heavy and powerful models have an energy of 15-20 joules. The diameter of the hole also depends on the force of the impact. That is, when choosing a tool with a minimum impact force, the hole diameter will be appropriate, and therefore small. It also plays an important role in the processing of various types of surfaces.
  • Some users claim that the impact energy is directly related to the current hand pressure on the tool holder. But in reality, things are quite different with this tool. The correct option would be to refuse a tool with an impact energy of more than 10 joules. The problem is the rapid deterioration of the construction tool. The fact is that powerful rock drills are subjected to the strongest pressure during operation, and this significantly reduces the service life.
  • Impact speed. A very important parameter during the work process is the impact speed. It directly depends on how quickly the required surface is processed. It shows the number of times the tool hits the surface per minute. Impact energy and speed - these are the indicators that you should pay attention to in the first place in the tools of the manufacturer Metabo. This manufacturer is famous for its speed and energy indicators have reached the highest quality.
  • Rotary hammer power. First of all, you need to know that the power in rock drills is much less than in standard drills. It all depends on the purpose of the tool, but in fact drilling requires more energy than drilling. It is worth considering this fact when choosing a tool. Professional users claim that the best models are hammer drills that consume no more than 800 watts during operation. This indicator will be enough for home use. Be that as it may, when buying rock drills from a German company, you can not pay much attention to the power indicator.

Important! When purchasing a hammer drill powered by a battery, you should pay attention to the battery life.

Many buyers confirm the decent quality of Metabo cordless rotary hammers.

Features of the workflow

The quality work of the purchased punch will ensure regular inspection and correct use of the tool. First you need to do the preparatory work, which includes cleaning the chuck, lubricating all internal parts and installing a working drill. Each preparatory work should be carried out according to the instructions provided by the manufacturer Metabo.

Improper use of the tool can result in serious damage and further failure of the rock drill.

It is worth considering that the described preparatory work must be carried out with the tool turned off. Before the working process, it is advisable to run the drill at idle speed.

Maximum safety during operation and a long service life will be ensured by the following recommendations:

  1. During the working process, do not create strong pressure on the rock drill. Otherwise, it will cause malfunction of the equipment or its surface. It is worth remembering that the level of pressure applied to the stick does not in any way affect the power and performance of the rock drill.
  2. Most users consider the correct workflow to be one-time drilling to the required size. Periodically, it is necessary to stop work and allow the drill to cool down, it is also worth cleaning it. This will greatly simplify your workflow.
  3. You need to choose the required drill, guided by the surface features and the type of drilling itself. It is best to take into account the presence of the Metabo hammer drill type. This can make a lot of things easier, as there are different adapters for the corresponding work.
  4. It is strictly forbidden to allow any deformation on the top of the rock drill body. Otherwise, this can not only worsen the performance of the tool, but even break it altogether. To prevent such occurrences, experts recommend purchasing rotary hammers with an aluminum housing. It is also important for faster cooling of the device.
  5. During the working process with the puncher, it is necessary to wear rubberized gloves, as this helps to reduce vibration on the hands. A distinctive feature of the drilling tool from the Metabo manufacturer is the presence of rubber inserts on many models. It also reduces vibration.

Basic principles of care

The reliability and long service life of the hammer drills from the manufacturer Metabo will ensure regular and high-quality maintenance of all the mechanisms of the device. Correct care and proper cleaning of parts guarantee a long overhaul period. The main feature of any tool is the periodic repair of its mechanisms and it does not matter how long the device has worked. Any build quality or other tool metrics available will not change this.

During maintenance, special attention is paid to the tightness of the gearbox lubrication. This is a very important factor, especially if the hammer drill is often used when working with reinforced concrete frames. In the event of a large amount of dust, it is imperative to clean and lubricate the rotating mechanism. Otherwise, the node may fail or burn out altogether.

When working with Metabo hammer drills, you need to remember that when using it at low speeds, the mechanism begins to instantly heat up. This indicates that the device must be periodically turned off and allowed to cool. At the end of the working process, all possible components of the device must be cleaned of dust. In any case, the processing rags must be as dry as possible, otherwise the tool may burn out the next time it is turned on.

Caring for the tool of the German company is quite easy, since access to the internal structure is very easy to get. This is evidenced by simple disassembly of the equipment. Also, there are special brushes available, which will ensure easy cleaning of the mechanism. As mentioned above, the manufacturer's assortment includes a huge range of rotary hammers, and this will allow any user to choose the desired option. If properly looked after and used percussion instrument, it will last a long time.

Now directly to the best models.
