Revolving Drill And Reverse

When choosing a drill, it is necessary to consider for what type of work it is purchased. With such a necessary tool as a drill, probably every owner is familiar. Its main function is drilling holes, but in addition it can be useful for many more actions. For example, in some ways even replace the screwdriver. Of course, a drill is a very useful thing, so its purchase should be taken as seriously as possible so that the tool really helps, and does not lie on the shelf idle.

Choosing an electric drill, it is worth first of all to figure out what they are? Over the entire period of its existence, this tool has received many varieties and was supplemented by a two-speed gearbox, reverse and other useful options.

The hammerless drill has light weight and small dimensions.

There are six main types of drills:

  1. Percussion. with the help of such percussion instruments you can drill almost any material. It can work in 2 modes: just drilling and drilling with impact.
  2. Unstressed. they are characterized by precision drilling. Such an electric drill will perfectly cope with metal, plastic or wood.
  3. Corner. such an aggregate has a rather narrow circle of action, but it is this drill that is indispensable when working in a limited space.
  4. Drill mixers. this device is designed to mix different materials using a variety of nozzles. You can mix adhesive solutions, varnishes, gypsum or cement mixtures, paints and other materials.
  5. A screwdriver. a drill. from the name it is clear that in addition to drilling with such a tool, it is possible to tighten various nuts and bolts. The difference from other types of devices is the presence of a torque limiter or drilling depth.
  6. Diamond drilling tools are professional drills that can handle brick and reinforced concrete. They are “dry” and “wet”. The latter deal with hard materials, and the former with soft ones.

This is how the basic classification of drills looks. Its main mechanism is an engine that generates force to rotate the drill. But since the rotational speed of the motor itself is much greater than the mode of rotation of the drill, drills provide for interaction with the gearbox, which, if necessary, reduces the overestimated frequency of rotation of the motor, and at the same time increase the rotation force on the drill. Such a gear drill is switched on, as a rule, with a trigger switch, which also controls the number of revolutions of the cartridge.

Standard passport for an electric drill and its device

To understand how an electric drill works, you need to understand how it works. To do this, you can see the technical passport of the device, where everything is clearly shown and painted.

Many electric drills have a special switch (reverse mode), which can reverse the direction of rotation of the drill

Some features of the device drills:

  1. Many models of drills have electronic speed control, which allows you to keep the desired speed even taking into account the load on the drill. over, there are special torque devices that protect the motor from combustion if the drill suddenly gets jammed.
  2. Impact drills are famous for their "ability" to work with particularly hard materials. This is helped by a special percussion mechanism, allowing you to make hundreds of strokes per second. True, for this, special drills are used, designed specifically for hammer drilling.
  3. Trigger lock. drills have a special button that can lock the trigger if you need long drilling. If you pull the trigger itself, the latch will release it.

By the way, the trigger itself is a switch that supplies power to the motor. In modern models, it is also equipped with a function of changing the speed of rotation. With this trigger, the operation of the drill depends on the degree of pressure on the trigger itself.

Recommendations: how to choose a drill for the house

Before choosing a drill, you should decide which class of tool you need. household or professional. And then make the final choice of the device. For home use, a domestic unit will be quite enough, especially if you have to use a drill infrequently.

When choosing a drill, you should keep in mind:

  1. Power. “home” drills can have this indicator from 500 watts to 1,000 watts. This value makes it possible to work with metal, wood, concrete and other materials.
  2. The presence or absence of a percussion mechanism. for work at home, it is desirable that there is a “punch”, since it is often necessary to perform a variety of work, where you need to check both the walls and other very different materials.
  3. Power. can be mains or battery. At home, the first option is quite suitable. True, it is better to stock up with an extension cord just in case.
  4. Rotational speed. usually this indicator is 500-1500 rpm. All drills have a special speed control switch that you need to use when working with different materials.
  5. Diameter of holes. these indicators can be found in the model passport. You need to know the maximum diameters so that you do not accidentally burn the tool on the first working day.
  6. Type of cartridges. for home use it is best to use a key chuck made of metal, which holds the drill bit securely. True, in this case, care must be taken not to lose the key to the cartridge itself.

When choosing a drill for home use, the frequency and intensity of work should be taken into account, since the model is household, it involves a short use

If the work is long, the drilling machine must be periodically cooled, turning it off from the network. It is especially necessary to do this if heat has started to flow from the drill body or the smell of burnt insulation is heard.

By the way, the rotation speed or the number of revolutions performed shows how the tool will behave during work with various materials. The larger this indicator, the higher the drill capabilities. Even if the power of the drill is small, a high rotation speed will block it. You can conduct a small test to verify this.

Analyzing all the moments, we can say that a household impact drill with a power of 500-800 W with speed control and reverse is best suited for a house.

Home Drill Rating

The Sparky BUR 150CET KL reversible drill is easy to use and light enough

So, the rating of impact "home" drills:

  1. Metabo SBE 900 Impuls. a very good drill with a power of 900 watts, with a two-speed gearbox, speed control, keyless chuck and the presence of reverse.
  2. Bosch GSB 21-2 RCT. reversible model with speed control. Easy to use, you can adjust the power.
  3. Sparky BUR 150CET KL can be used as a wrench or screwdriver. There is overload protection and speed control.
  4. Makita HP 2051 F. low power, but rather quiet operation, the presence of illumination of the drilling site and two speeds.
  5. Bison MASTER DU-810 ERM2. inexpensive, but with very good equipment. Light weight, comfortable to work with. There is a reverse and speed control. One speed mode.

For mixing, drilling and screwing, it is better to purchase a universal tool with a high reliability class. But if you need a drill just for a certain type of work, the best option would be to buy a device with this particular function.
