One of the most necessary tools during construction or repair is a perforator. With the advent of this device, which is able to withstand high loads, the craftsmen perform the work with ease and comfort. The choice of such devices in the market of building materials is huge today, they are offered by almost every company that specializes in the manufacture of tools. But if you decide to prefer the Dewalt puncher, then you need to understand the models to make the right choice, because you have to spend a considerable amount.
Features of choice
In order to purchase a model that will satisfy your requirements, you need to familiarize yourself with the principle of operation and design features of the equipment. Tools of the mentioned brand can work in one or two modes. In the first case, you can drill, and in the second, you can also use the impact function. You can prefer a model with three modes, a chiselling will be added to the previous two.
Among other things, such devices are divided into light, medium in weight and heavy. The first will have a weight that does not exceed 4 kilograms, but with average weights this parameter varies from 4 to 5 kilograms. As for heavy appliances, they can weigh up to 10 kilograms or more.
Main characteristic - impact energy
If you decide to buy a Dewalt punch, then you must first pay attention to the impact energy, which is one of the main parameters of the described device. It is measured in joules. In this case, it is worth being guided by the mass of the model.
Thus, if the Dewalt puncher belongs to the easy version, then the force of its impact will vary from 1 to 2 joules. As for the middle-class rotary hammers, the mentioned parameter varies from 8 to 15 joules. With an increase in impact energy, you can count on a more impressive hole diameter. When this value is small, the device does not work as efficiently. In this case, the tool will not punch, but drill holes. In the end, you may run into the problem that the tool will wear out extremely quickly, and you won’t have to dream about high performance. If we are talking about impact energy, it must be remembered that it does not depend on what force acts on the handle.
For reference
As for working with a percussion drill, things will be the other way around. According to users, if the impact force is more than 10 joules, then this can cause an early failure of the tool. The problem is due to impressive loads and refractory inserts, which are destroyed in a short time.
Beat Frequency Reviews
If you are interested in the Dewalt puncher, then, as experienced craftsmen emphasize, you should pay attention to the frequency of strokes. This parameter determines how many times in one minute the piston hits the hammer. The larger this parameter is, the higher the punching speed will be. The tool has a performance that depends on the energy and frequency of the impact. The described company produces effective and durable devices that harmoniously combine the above parameters in the models. This opinion is expressed most often by consumers, and is confirmed by the fact that Dewalt brand products are one of the most common on the market.
Power Reviews
The Dewalt rotary hammer, which you should read the reviews before visiting the store, has higher power compared to electric drills. This is due to the fact that drilling is harder for the master than drilling. For this reason, the tool shaft during operation does not imply a high speed of rotation. Considering different devices with certain types of cartridges, you will notice that their power varies. If the equipment has an SDS-Plus cartridge, then the power will vary from 400 to 800 watts. If you have an SDS-Max cartridge in front of you, then the power will vary from 1 to 1.2 kilowatts. Experienced craftsmen are not advised to choose a tool, guided by power, since this parameter is not the most important.
Spindle Speed Reviews
If you need a Dewalt rotary hammer, the repair of which you would not want to carry out often enough, you should pay attention to the spindle speed. Depending on the class of equipment, the value of this value can vary from 600 to 1500 revolutions in one minute. If you prefer a less productive and less powerful punch, you can count on a not-so-high speed. This can be explained by the fact that the most suitable tooling diameters are large enough for productive versions of rotary hammers.
As users emphasize, if the model has a high shaft rotation speed, then it will have an impressive weight, which will not facilitate the use. Among other things, such high-speed units wear out quickly, which is especially true for spiral grooves. Consumers emphasize that at the same time the device heats up very much, as a result of which the working element may jam in the hole.
Customer reviews of additional features
If you are interested in the Dewalt D25123K rotary hammer, reviews of which are only positive, then you should consider that it has some additional functionality, namely a depth limiter, the ability to switch speeds, soft start, and frequency stabilization. The first functionality, according to consumers, allows you to find out if the drill has reached the required mark. As for the possibility of switching speeds, such a mechanism is useful in cases where it is necessary to transfer the tool from the drill to the drill and back. After all, these elements must move at certain speeds. Experts say that the reverse rotation of the shaft is a very convenient mechanism, which is necessary when the drill gets stuck in the surface.
During operation, it may be necessary to purchase a brush for the Dewalt rotary hammer. According to experienced specialists, the described company provides the opportunity to buy supplies in any store or service centers, which is very convenient. If you want to avoid trouble like device breakdowns, you should choose the option with the ability to soft start, which eliminates the possibility of overheating. A very useful function is the stabilization of the shaft rotation speed under load.
Dewalt Advanced Hammer Drill Reviews
The Dewalt cordless rotary hammer allows you to work in areas where it is not possible to connect the tool to the mains. In addition, you should take into account that the model does not interfere with dust protection, because in sterile conditions during construction it is possible to work very rarely. No less convenient is the anti-vibration system, it, according to consumers, softens the shaking of the tool during chiselling, drilling and drilling. When choosing a specific model, you should consider the presence of certain functions, each of which can be useful to you during the operation of the tool. Do not overpay for equipment whose functions you will not use to the full.
