What is a perforator? This is a type of power tool designed for construction work. By the way, some beginners often confuse a hammer drill with an impact drill. With external similarity and similar characteristics, these tools have one significant difference. We are talking about a different device of the percussion mechanism, which is clearly more powerful than the perforator. So, thinking about buying, a person will invariably face a difficult choice: rotary hammers are presented on the market in a fairly wide range. Here we will consider one model from this category of power tools - MAKITA HR2450. Let's analyze all the technical features and see what customer reviews say.
First impression
The MAKITA HR2450 puncher is positioned by manufacturers as a tool designed for professional use. From the general characteristics that are indicated on the price tag, you can find out the following features:
- Perforator power - 780 watts.
- Chuck type - SDS Plus.
- There are three operating modes: normal drilling, drilling accompanied by impact, chiselling (impact without drilling).
- The number of speeds is one.
This information is too little to have a complete picture of the tool. You should not completely trust the words of the seller either: this is an interested person. Therefore, we will be guided by our own impressions and opinions of customers.
At the initial examination, the Makita 2450 makes a positive impression. The tool is made in a two-tone version: blue and black, there are special rubberized pads on the handle. The build quality is quite decent, there are no backlashes, the plastic shell sits like a glove. The product comes with a special storage case. This is a very important nuance: some manufacturers do not include a case in the basic package.
The mass of the product is 2.4 kilograms, an additional handle is provided, which allows you to apply more effort when chiseling hard materials. The puncher is equipped with a rather long electric cable - 4 meters. The basic package includes a drilling depth limiter, however, there are no drills.
Makita 2450 SDS Plus x8 is made in China. One year manufacturer's warranty from date of purchase.
Specifications
The power consumption of the MAKITA HR2450 is 780 W, which makes it possible to work with almost any type of building materials (wood, metal or concrete). The nominal impact energy is 2.7 J. Please note that each material has a maximum allowable hole diameter. In particular:
- For wood - 32 mm.
- For metal - 13 mm.
- For concrete coatings - 24 mm.
These parameters are obtained by manufacturers as a result of technical tests. It is not recommended to exceed the set values: the probability of wear of the electric motor increases, respectively, the tool life is reduced.
The maximum number of revolutions of the chuck in drilling mode is 1,100 rpm. Impact frequency - 4,500 beats / min. Please note that these specifications are relevant for the tool to idle. When the drill is immersed in the material, the speed and impact frequency are reduced.
One chuck is included in the basic package. Cartridge type SDS Plus. By the way, this nuance suggests that the tool is intended for domestic use. Therefore, manufacturers are cunning, declaring this model of a perforator as a professional tool. SDS Plus is designed to work with drills, the shank diameter of which does not exceed 10 mm. Professional rotary hammers use the SDS Max chuck, which is suitable for 18 mm shanks.
Useful options include the following:
- Automatic blocking - turns on when the voltage drops in the mains.
- A protective system that prevents debris from entering the tool.
- Safety clutch - breaks the coupling of the chuck and the engine when the drill is jammed.
- Reverse - changes the direction of rotation of the drill to the opposite.
- Speed controller.
These are the basic characteristics declared by the manufacturer. Experts know that all the advantages and disadvantages of the tool can be revealed only in the process of work. Therefore, let's see what they say about the Makita 2450 puncher customer reviews.
Advantages
To begin with, we give positive reviews, where the strengths of this model are noted.
- Hard case for storage. The presence of this accessory automatically solves the problem with the delivery of the tool to the place of work and simplifies storage. By the way, the external dimensions and internal space are optimized as much as possible: nothing superfluous.
- Three working modes. This feature allows you to use an electric rotary hammer as a drill or a jackhammer. In combination with good power (780 W), the tool shows good performance and functionality. The working chisel can be fixed in 40 positions.
- Ease of use. The puncher weighs only 2.4 kilograms, respectively, you can perform work even with one hand. At the same time, the tool does not slip out of the palm thanks to rubberized pads. When chasing walls, especially under the ceiling, an additional handle helps a lot. This element is removable, so if desired, it can be easily removed.
- SDS Plus quick release chuck. The advantage of this type of chuck is that the drill shank is fixed at five points. This ensures the reliability of fastening, however, if necessary, you can replace the drill with just one movement.
- Long cord. The presence of a four-meter cable allows you not to use carriers when performing work.
- Protection. This includes a safety clutch and a reverse function. When the drill jams, the load on the electric motor automatically increases, the winding burns out accordingly, and the tool is sent for repair. Installing a clutch avoids such unpleasant consequences. Thanks to the reverse function, you can easily pull out a jammed drill without swinging the tool.
- Smooth start. This feature reduces the load on the motor at start-up, extending tool life.
- Rugged housing. High-strength plastic is used here, so even when falling, cracks and chips do not appear on the case.
- Acceptable price. The cost of an electric rotary hammer MAKITA HR2450 starts from 6,300 rubles.
Flaws
Customer reviews say that this model has practically no flaws. However, there are still design flaws. Here are the weaknesses of the Makita 2450 puncher:
- Oil leaks. After lubricating the drill shank, part of the oil flows out onto the chuck during operation.
- Overheat. Buyers note that during operation, the rotary hammer gearbox is very hot. The problem may be caused by poor quality parts (virtually excluded) or non-compliance with the rules for operating a power tool. In particular, exceeding the permissible loads on the percussion mechanism.
- There is no vibration protection mechanism.
- Very poor basic equipment.
Conclusion
MAKITA HR2450 is well worth the money spent on the purchase. The tool is suitable for professional and home use. Thanks to its extended functionality, it can be used for repair and construction work. In particular, a power of 780 W is enough to dismantle old facings, lay hidden wiring and make new communication holes in concrete ceilings and brick walls.
If the manufacturer's requirements are observed, the tool can last for a long time without requiring service. If we summarize the identified shortcomings, then we will not see significant problems.Of course, manufacturers could complete their power tools with drills without incurring additional costs for buyers. Or fix the problem with the leakage of lubricant from the chuck. But these shortcomings do not affect the performance and functionality of the product. Therefore, the MAKITA HR2450 electric rotary hammer with a power of 780 W can be rated at 8 points out of 10 possible.
