One of the most necessary tools for construction or repair is a perforator. With the advent of this device, which is able to withstand high loads, the masters perform work with ease and comfort. The choice of such devices on the building materials market today is huge, they are offered by almost every company that specializes in the manufacture of tools. But if you decide to prefer a Dew alt rotary hammer, then you need to understand the models in order to make the right choice, because you will have to spend a considerable amount.
Features of choice
In order to purchase a model that will meet 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, to the previous two will be addedchiselling.
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 medium masses 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 Dew alt puncher, then you need, first of all, to 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, you should be guided by the mass of the model.
Thus, if the Dew alt perforator belongs to the light version, then the force of its impact will vary from 1 to 2 joules. As for the middle class punchers, the mentioned parameter varies from 8 to 15 joules. As the impact energy increases, you can count on a larger 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 equipment will wear out extremely quickly, and you will not have to dream of high performance. When it comes to impact energy, it must be remembered that it does not depend on what force acts on the handle.
For reference
As for working with an impact drill, it will be the other way around. As they sayusers, if the impact force is more than 10 joules, it may cause the tool to fail soon. The problem is caused by impressive loads and refractory inserts, which are destroyed in a short time.
Stroke rate reviews
If you are interested in a Dew alt puncher, then, as experienced craftsmen emphasize, you should pay attention to the frequency of impacts. This parameter determines how many times in one minute the piston hits the firing pin. The larger this parameter is, the higher the hole punching speed will be. The tool has a performance that depends on the energy and frequency of impact. The described company produces efficient and durable devices that harmoniously combine the above-mentioned parameters in the models. This opinion is expressed most often by consumers, and is confirmed by the fact that Dew alt brand products are one of the most common on the market.
Power Reviews
The Dew alt rotary hammer, which you should read reviews about before visiting the store, has more power than electric drills. This is due to the fact that it is harder for a master to drill than to drill. For this reason, the tool shaft does not require a high rotation speed during operation. Looking at 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 800watt. If you have an SDS-Max cartridge in front of you, then the power will vary from 1 to 1.2 kilowatts. Experienced craftsmen do not recommend choosing a tool based on power, as this parameter is not the most important.
Spindle speed feedback
If you need a Dew alt rotary hammer that you don't want to repair often enough, then 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 per minute. If you prefer a less productive and less powerful hammer, you can count on a not so high speed. This can be explained by the fact that for productive variants of rotary hammers, the most suitable tooling diameter is large enough.
As users emphasize, if the model has a high shaft speed, then it will have an impressive weight, which will not facilitate use. Among other things, such high-speed units wear out quickly, which is especially true for spiral grooves. Consumers emphasize that in this case the device becomes very hot, as a result of which the working element may jam in the hole.
Consumer feedback on additional features
If you are interested in the Dew alt 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, softstarting, as well as 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 a drill to a drill and vice versa. 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 in the event that the drill gets stuck in the surface.
During operation, it may be necessary to purchase brushes for the Dew alt perforator. According to experienced specialists, the described company provides the opportunity to buy consumables in any store or service center, which is very convenient. If you want to avoid troubles like device breakdowns, then you should choose the option with the possibility of soft start, which eliminates the possibility of overheating. A very useful feature is the stabilization of the shaft rotation speed under load.
Feedback on models of Dew alt brand rotary hammers with additional features
The Dew alt 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 dust protection will not interfere with the model, because it is very rare to work in sterile conditions during construction. Equally convenient is the anti-vibration system, which, according to consumers, softens the shaking of the tool when chiselling, drilling and drilling. AtWhen choosing a particular model, you should take into account the presence of some functions, each of which may be useful to you during the operation of the tool. Do not overpay for equipment whose functions you will not use to the full.
