How to choose dremel

Engraver is a tool with which the master works with metal, plastic and other material. Surprisingly, often the male engraver is more familiar to the weaker sex, especially those who often visit nail extension masters. Yes, yes, do not be surprised, it is the low-powered engraver that grinds female claws. If you want to approach the choice of this tool professionally, then learn more about 4000 vs. 4300.

How the engraver works

Direct grinder is a kind of hybrid drill and a large fountain pen. Hiding under the body:

  • electric motor of various power (depending on the purpose of the engraver),
  • gearbox
  • spindle (shaft), the length of which depends on the scope of the tool. To cool the electric motor, a plastic impeller is placed on the spindle of the engraver, which creates air flow along the entire motor through the air intake openings.

The principle of the engraver is similar to a conventional drill. It weighs a little more than a kilogram, so it’s convenient for them to work with one hand. Every direct grinder model is equipped with a speed controller. In the budget version, this is the simplest divider based on a rheostat, which controls the voltage on the electric motor. In professional models – an advanced electronic filling that keeps the given speed constant at any load.

What to look for when choosing an engraver

If you decide to buy an engraver, you need to pay attention to the following nuances.

Ergonomics and weight. The weight of direct grinders ranges from less than 1 kg to 7-8 kg. If you hold the tool for a long time and work with small objects, you should purchase an engraver with a minimum weight. Then your hands will not get tired too quickly.

An important point is the ergonomics of the grinder:

  • how comfortable the device sits in your palm
  • how pleasant it is to the touch, whether it slips out.

Attention should be paid to the quality of the engraver and the material from which it is made, to the assembly of the model. Ease of use is of course everyone’s personal business, so before buying, be sure to pick up a tool, feel its weight and dimensions.

Remember to check:

  • are the nozzles easy to change;
  • is the flexible shaft mounted on the engraver;
  • are there any backlashes and creaks;
  • is the power cord attached securely?

Noise and vibration

Most manufacturers in the instructions for engravers do not give information about the level of noise and vibration. But the tool with small dimensions and light weight really creates a low noise level. It is several times quieter than a conventional drill, so when you use it at home, you don’t worry about neighbors. Strong vibration is also not characteristic of this device.

Heat dissipation

An important criterion for the engraver to work is the heat generated by the electric motor. Excessive heat generation can cause engine damage. The increase in temperature inside the engine increases in three cases:

  • in case of violation of the external cooling conditions (external heat removal);
  • when exceeding the permissible current;
  • when exceeding the permissible torque on the shaft.

In addition, the engraver adapter may overheat. But nothing dangerous will happen if you operate the device according to the instructions.

Safety precautions when using an engraver

When using an engraver, like other power tools, safety precautions should be followed. When working with glass, ceramics, brittle materials, wear safety glasses. If a lot of dust, shavings, and fine waste forms during the process, put on a protective bandage for your nose and mouth. It is also advisable to protect your hands. It all depends on what material you work with. In conclusion, I would like to note once again: when choosing an engraver, be guided, first of all, by the goals and the amount that you are willing to spend on it.
