Best Hitachi Rotary Hammers 2020

The spectrum of construction work cannot be done with a single hammer and nails. Therefore, you have to prepare for such work in advance. Tools and devices for various purposes can reduce the burden on a person, save energy. This also applies to rotary hammers, which today are produced by various brands, including the Japanese company Hitachi.

In the past, the main problem in construction was the correct fixation of different materials. This ruined the aesthetics and ease of renovation. Therefore, the person had to get out, think over the process of erecting buildings in a convenient way. With such thoughts, ideas appeared about clamps and clamps that are attached to the base (wall, floor, ceiling). Their function was to maximally synchronize the junction of two elements in construction.

The architects liked this idea, but difficulties lay in wait in the very creation of the fasteners. The holes for them took longer than the docking itself. It is necessary that the holes adjoin as closely as possible to the auxiliary elements, be able to hold impressive loads without subsidence. Real craftsmen could make perfect holes, and their services cost a lot of money. Because of this, people began to sort out ideas to facilitate this process. In desire, the first prototype of such a tool as a perforator appears. A unique machine capable of quickly and accurately making a hole in any surface. It doesn't matter whether through holes or blind holes.

What is a rock drill?

A hammer drill is a construction hand tool that runs on electricity or on a battery, and its working part performs percussion movements with rotation. Thanks to such a simple model of work, the surface is not sprinkled, the top layer does not break off.

 

Its components can be perfectly seen in the figure.

Despite its simplicity, the hammer drill is considered a dangerous device, as it exposes the power grid to additional loads. May cause physical damage to the user if used carelessly.

When is the puncher used?

Due to its simple and efficient design, it is possible to use the tool with several modes. A simple mode regulator allows a person to easily switch from one work option to another. Before that, it is recommended to stop the work before the complete stop of the work item. The kit often contains several attachments that expand its functionality in the construction industry. The puncher is used for:

• Punching through holes in a variety of surfaces;
• Making blind holes for dowels and anchors;
• For working with metal materials;
• Shtrobleniya building materials to create space for an eclectic network, water supply and sewerage system.

Today, various models with additional functions and capabilities began to appear.Now the hammer drill is used not only for creating the necessary holes.

Best punchers Hitachi films in 2020

Such a narrowly focused instrument from the outside does not seem so significant in the everyday life of any person, so some carelessly buy equipment or completely ignore it. Over time, when a serious need for use arises, a person has to rake up additional problems associated with the complication of using a purchased mediocre tool. To prevent this from happening, we recommend that you pay attention to the Hitachi rotary hammers, which hold the leadership in the world market for this kind of tool.

Hitachi DH28PC

Small and compact tool. Features a comfortable rubber grip to cushion vibration during operation. The auxiliary handle, which allows the second hand to better control the tool, is located on the side. This reduced the risk of injury while working. Power of 720 W allows you to spin the working mechanism up to 4 thousand revolutions per minute. I was pleased that at idle speed the rotation speed reaches 1040 rpm. This is sufficient for drilling neat and thin holes in dense materials such as reinforced concrete. At maximum intensity of work, the tool produces one impact per revolution. That is, the ratio of the number of revolutions to blows is 1 to 1. This simplifies the work and speeds up the advance of the nozzle through the material. The tool is actively used when working with metal, concrete, mild steel and wood. The total weight of the rock drill is 3.5 kilograms. The cost of this tool will be at least 24 thousand rubles.

• The presence of three modes of operation;
• Rubberized handle;
• There is a shock blocking mechanism.

• Too thin nozzle diameter when drilling mild steel - only 13 mm;
• Impact energy is rather weak, only 3.5 J.

Hitachi DH38MS

A powerful professional machine with impressive characteristics, it easily makes holes in most building materials. A rather heavy and oversized tool (the whole is more than 6 kg) is not recommended for inexperienced workers. Huge vibrations can lead to accidents. Electric hammer drill with a power of 950 W, capable of accelerating to 4400 rpm. The impact force is 8 J. This significantly reduces the time to create the required hole. But remember that this RPM will be harder to control. The motor is positioned horizontally, which eliminates the load on the supporting arm. The grips have a rubber layer that dampens vibrations during operation. The diameter of the nozzle (drill) in concrete is 26 mm, which is enough for dowels. It is actively used in general areas and at home. We recommend that an inexperienced owner read the instructions before active work. The average cost of this instrument is 36 thousand rubles.

• Powerful;
• Awesome choice of drill diameter;
• Rubber grip.

• Strong vibrations;
• Heavy.

Hitachi DH52MEY

To be fair, we will add a professional, heavy and incredibly powerful hammer drill, which is used by experienced workers on large construction sites. Hitachi DH52MEY is a twelve-kilogram tool that only a seasoned builder can tame. The electric motor consumes at least 1.5 kW for operation under intense loads. All this is compensated by the huge drilling attachments. In concrete, the hole diameter can be up to 52 mm.The engine is positioned vertically, which will force some people to adjust. The impact energy is a staggering 15 J. This automatically makes the device one of the most physically unstable. That is, a beginner will not be able to master such an instrument alone the first time. Despite such technical characteristics, the maximum number of revolutions per minute does not exceed 2400. However, with such a force of impact, this is enough for fast work on any surface. Idling also does not inspire confidence, only 280 rpm. The price for this powerful unit is 65 thousand rubles.

• Powerful;
• Drill diameter;
• Works with any surface.

• Heavy;
• Impressive vibration force at maximum load.

Hitachi DH26PC

Sometimes you don't need to buy a powerful tool for home use. A simple Hitachi DH26PC is enough, which is suitable for working with small planes. A light hammer drill with a power of 830 W is perfectly compensated for by a good blow. The maximum number of revolutions is 4300. Weighing 2.8 kg, some workers will need to practice first. A tool that is too light for this intensity can fail after prolonged use. The horizontal orientation of the motor slightly increases the operating time, but does not prevent overheating. An additional handle for convenience is located at the bottom, which makes working at high levels inconvenient. Three full-fledged operating modes allow you to use the hammer drill. The average cost of a Japanese hammer drill is 11 thousand rubles.

• Three operating modes;
• High speed;
• Drilling depth stop.

• Too light;
• The additional handle is at the bottom.

Hitachi DH28PCY NX

An average working version that will last a long time and without breakdowns. The complete hammer drill has all the features of expensive professional analogs. With 850 watts of power, it can handle a variety of materials with ease. Three full-fledged operating modes: drilling, punching and drilling with a punch, which turns the model into a universal tool for home and garden. The impact energy, unfortunately, leaves much to be desired and is only 3.4 Joules. With its compact dimensions, it spins the working part up to 4300 rpm. The horizontal orientation of the engine is a little interfering during operation, but not critical. The number of idle revolutions is 1100, which is enough to create through holes in wood and concrete. There is a huge start button that allows you to quickly turn off the appliance if you lose control. The reversing system makes it easy to create holes. The wear-resistant casing can withstand sudden changes in temperature inside, easily transfers significant moisture. The additional handle can be adjusted to suit your own preference. Inside there is an impressive air cooling system for the instrument. There is a limiter with which you can adjust the depth of the blind hole. The purchase price will be at least 15 thousand rubles.

• Multifunctional;
• High speed;
• Not a bad cooling system.

• Impact strength;
• There is no speed control.

Hitachi DH24PH

One of the most affordable options for buying at home use. Hitachi DH24PH has never claimed to be the best rock drill ever. It contains the basic features of the tool, without unnecessary additional functions. Works with concrete, metals and wood. The power of 730 W does not allow for long-term intensive work. The engine will heat up quickly. The air cooling system has no time to circulate the air. Therefore, this model is effective at maximum power, but with frequent interruptions. The device is capable of making up to 3950 rpm per minute. Not a bad figure for a hammer drill, which has an impact force of 2.7 Joules. As in most of the analyzed variants, it has three modes of operation.The special shape of the case greatly simplifies its use. It is easier for a person to hold the Hitachi DH24PH while working. The overall dimensions are halved when compared to previous models. To compensate for the weak drilling system, the device used an improved internal pressure control mechanism. It allows you to use the hammer drill outside the specified technical capabilities for a few minutes. But this is highly discouraged to avoid injury and tool breakage. The average cost is 10,500 rubles.

• Lightweight and comfortable;
• Three operating modes;
• Price.

• Weak air control system;
• Power.

Hitachi DH30PC2

Let's move on to more versatile options. Hitachi DH30PC2 is a very special rotary hammer in the range. It has the highest power consumption of 1.7 kW. This makes it a dangerous tool in the hands of an inexperienced worker. An additional rubber grip allows you to hold this tool while working. The huge engine is located behind a housing resistant to various damages. There are three standard operating modes, and the reverse function allows you to make a minimum of effort during the execution of simple production tasks. Such a tool is perfect for long-term work when there is a need for prolonged use with maximum intensive load. The impact energy is at an average level, and is only 5.4 J. For huge modern buildings this is not enough, but for home use - just right. 3.7 thousand rpm is not the highest, but in sync with good strength, the hammer drill is capable of performing various tasks. Easily drills through metals, concrete slabs and wood. There is an anti-vibration system that minimizes stress on the hands. Such a good puncher will cost 40 thousand rubles.
