How to choose a drill with reverse and speed control
When choosing a drill, it is necessary to take into account what type of work it is purchased for With such a necessary tool as a drill. probably every owner is familiar. Its main function is drilling holes, but besides this, it can be useful for many more actions. For example, in some way 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.
When choosing an electric drill, it is worth first of all to figure out what they are? Throughout its existence, this tool has received many varieties and was supplemented with a two-speed gearbox, reverse and other useful options.
The hammerless drill is light in weight and small in size
There are six main types of drills:
- Impact. With these impact tools, you can drill almost any material. Can work in 2 modes: simple drilling and hammer drilling.
- Shockless. differ in drilling accuracy. Such an electric drill will perfectly cope with metal, plastic or wood.
- Angular. such a unit has a rather narrow range of action, but this particular drill is indispensable when working in a confined space.
- Drill mixers. such a device is designed to mix different materials using a variety of attachments. You can mix adhesive solutions, varnishes, gypsum or cement mixtures, paints and other materials.
- A screwdriver. a drill. from the name it is clear that in addition to drilling, you can tighten various nuts and bolts with such a tool. The difference from other types of devices is the presence of a torque limiter or drilling depth.
- Diamond drilling tools are professional drills capable of tackling brick and reinforced concrete. There are “dry” and “wet”. The latter cope with hard materials, and the former with soft.
This is the main classification of drills. Its main mechanism is the motor, which generates the force to rotate the drill. But since the rotation speed of the motor itself is much higher than the rotation mode of the drill, the drills provide for interaction with the gearbox, which, if necessary, reduces the overestimated speed of the motor, and at the same time increases the rotation force on the drill. Such a geared drill is turned on, as a rule, with a trigger switch, which also controls the number of revolutions of the chuck.

Recommendations: how to choose a drill for home
Before choosing a drill, you should decide what class of tool you need. household or professional. And then make the final choice of the device. For home use, a household unit will be quite enough, especially if you have to use a drill infrequently.
When choosing a drill, keep in mind:
- Power. home drills can range from 500W to 1,000W. This value makes it possible to work with metal, wood, concrete and other materials.
- The presence or absence of an impact mechanism. for working at home, it is desirable that the “blow” was, since often you have to do a variety of work, where you need to check both walls and other various materials.
- Power supply. can be mains or rechargeable. At home, the first option is quite suitable. True, it’s better to stock up on an extension cord just in case.
- Rotational speed. usually this figure is 500-1500 rpm. All drills have a dedicated rotational speed control knob, which should be used when working with different materials.
- Hole diameter. these indicators can be found in the model passport. Knowing the maximum diameters is necessary in order not to accidentally burn the tool on the very first working day.
- Chuck Type. For home use, it is best to use a metal key chuck that holds the drill securely. True, in this case, you need to ensure that you do not lose the key to the cartridge itself.
When choosing a drill for home use, you should take into account the frequency and intensity of work, since the model is household, it assumes a short-term use
If the work is to be done for a long time, the drilling machine must be periodically cooled by unplugging it from the network. It is especially necessary to do this if heat has gone from the drill body or the smell of burnt insulation has become audible.
By the way, the speed of rotation or the number of revolutions performed shows how the tool will behave when working with various materials. The higher this indicator, the higher the capabilities of the drill. Even if the power of the drill is small, the high rotational speed will override this. You can do a little test to make sure of this.
Analyzing all the points, we can say that a household impact drill with a power of 500-800 W with speed control and reverse is best suited for home.
Electric drill with reversing and speed control
For mixing, drilling and screwing, it is better to purchase a universal tool with a high class of reliability. But if you just need a drill for a certain type of work, the best option would be to buy a device with this function.

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 look at the technical data sheet of the device, where everything is clearly shown and painted.
Many electric drills have a special switch (reverse mode) that can reverse the direction of rotation of the drill.
Some features of the drill device:
- Many models of drills have electronic speed control, which allows you to maintain 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 is suddenly jammed.
- Impact drills are renowned for their ability to work with particularly hard materials. A special percussion mechanism helps in this, which allows hundreds of blows per second. True, for this, special drills are used, designed specifically for hammer drilling.
- Trigger lock. drills have a special button that can lock the trigger in case of 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 for changing the rotation speed. With this trigger, drill operation depends on how much the trigger is pressed.

DIY drill repair
Replacement of brushes. The most common type of breakdown is wear on the engine brushes, which you can replace yourself at home. Sometimes, the brushes can be replaced without disassembling the drill body. For some models, it is enough to unscrew the plugs from the installation windows and install new brushes. For other models, disassembly of the case is required for replacement, in this case it is necessary to carefully remove the brush holders and remove the worn brushes from them.
Do not wait for the brushes to wear to their minimum size. This is fraught with the gap between the brush and the collector plates. As a result, increased sparking occurs, the collector plates become very hot and can “move away” from the base of the collector, which will lead to the need to replace the armature.
The need to replace the brushes can be determined by the increased sparking, which is visible in the ventilation slots of the case. The second way to define it is chaotic “jerking” drills during work.
Power cord. The cord is checked with an ohmmeter, one probe is connected to the contact of the power plug, the other to the core of the cord. Lack of resistance indicates an open circuit. In this case, repairing the drill is reduced to replacing the mains wire.
Diagnostics of the electric motor. In second place, in terms of the number of drill breakdowns, you can put a malfunction of engine elements and, most often, anchors. Failure of the armature or stator occurs for two reasons. Improper operation and poor quality winding wire. World-renowned manufacturers use expensive double-insulated wire with heat-resistant varnish, which significantly increases the reliability of engines. Accordingly, in cheap models, the insulation quality of the winding wire leaves much to be desired. Incorrect operation is reduced to frequent overloading of the drill or prolonged work, without interruptions to cool the engine. Do-it-yourself drill repair by rewinding the armature or stator, in this case it is impossible without special devices. Only the replacement of the element completely (only experienced repairers will be able to rewind the armature or stator with their own hands).
To replace the rotor or stator, it is necessary to disassemble the housing, disconnect the wires, brushes, if necessary, remove the drive gear, and remove the entire motor along with the support bearings. Replace the defective element and reinstall the engine.
The malfunction of the armature can be determined by the characteristic smell, an increase in sparking, while the sparks have a circular motion in the direction of the armature movement. Pronounced “burnt” the windings can be seen by visual inspection. But if the engine power has dropped, but there are no signs described above, then you should resort to using measuring instruments. Ohmmeter and megohmmeter.
The windings (stator and armature) are subject to only three damages. Turn-to-turn electrical breakdown, breakdown on “body” (magnetic circuit) and winding breakage. The breakdown to the case is determined quite simply, it is enough to touch any output of the winding and the magnetic circuit with the megohmmeter probes. Resistance over 500MΩ indicates no breakdown. It should be borne in mind that measurements should be carried out with a megohmmeter, which has a measuring voltage of at least 100 volts. Making measurements with a simple multimeter, it is impossible to determine for sure that there is definitely no breakdown, however, it can be determined that there is definitely a breakdown.
It is quite difficult to determine the interturn breakdown of the anchor, unless, of course, it is visible visually. To do this, you can use a special transformer, which has only a primary winding and a rupture of the magnetic circuit in the form of a trough, to install an armature in it. In this case, the armature with its core becomes the secondary winding. Turning the armature, so that the windings are in operation one by one, we apply a thin metal plate to the armature core. If the winding is short-circuited, then the plate begins to rattle strongly, while the winding heats up significantly.
Often, turn-to-turn closure is detected on visible sections of the wire or armature bus: the turns can be bent, crumpled (i.e. pressed against each other), or there can be some conductive particles between them. If so, then it is necessary to eliminate these short-circuits, by correcting the bruises of the tire or removing foreign bodies, respectively. Also, a short can be detected between adjacent collector plates.
You can determine the breakage of the armature winding if you connect a milliammeter to the adjacent armature plates and gradually turn the armature. In whole windings, a certain identical current will occur, the break will show either an increase in current or its complete absence.
A break in the stator windings is determined by connecting an ohmmeter to the disconnected ends of the windings, the absence of resistance indicates a complete break.
Regulator of turns and reverse. The presence of voltage at the input terminals of the power button and the absence at the output terminals indicates a malfunction of the contacts or components of the speed controller circuit. You can disassemble the button by gently picking up the latches of the protective cover and pulling it off the button body. A visual inspection of the terminals will allow you to judge their performance. Blackened terminals are cleaned of carbon deposits with alcohol or fine sandpaper. Then the button is reassembled and checked for contact, if nothing has changed, then the button with the regulator must be replaced. The speed controller is made on a substrate and is completely filled with an insulating compound, therefore it cannot be repaired. Another characteristic malfunction of the button is the erasure of the working layer under the rheostat slider. The easiest way out. Replacing the entire button.
Do-it-yourself drill button repair is possible only if you have certain skills. It is important to understand that after opening the case, many switching parts will simply fall out of the case. This can be prevented only by smoothly lifting the lid initially and the desired sketch of the location of the contacts and springs.
The reverse device (if it is not located in the button body) has its own changeover contacts, therefore it is also susceptible to contact loss. The disassembly and cleaning mechanism is the same as the buttons.
When buying a new speed controller, you should make sure that it is designed for the power of the drill, so with a drill power of 750W, the controller must be rated for a current of more than 3.4A (750W / 220V = 3.4A). And by the way, the regulator of the drill in the photo is not native, and in order for it to fit into the body, the lower part of the trigger was cut off.
The wiring diagram, and in particular the wiring diagram for the drill button, may differ in different models. The simplest diagram, and the one that best demonstrates the principle of operation, is as follows. One lead from the power cord connects to the governor.
In order not to get confused, it is important to understand what the speed controller and reverse control device are. They are two different parts that often have different bodies.
The only wire leaving the governor is connected to the beginning of the first stator winding. If there was no reversing device, the end of the first winding would be connected to one of the rotor brushes, and the second rotor brush would be connected to the beginning of the second stator winding. The end of the second stator winding leads to the second wire of the power cord. That’s the whole scheme.
The change in the direction of rotation of the rotor occurs when the end of the first stator winding is connected not to the first, but to the second brush, while the first brush is connected to the beginning of the second stator winding.
In the reverse device, such a switching occurs, so the rotor brushes are connected to the stator windings through it. This device may have a diagram showing which wires are connected internally.
Black wires lead to the rotor brushes (let the 5th contact be the first brush, and let the 6th contact be the second brush), gray. To the end of the first stator winding (let it be the 4th contact) and the beginning of the second (let it be the 7th contact). With the switch position shown in the photo, the end of the first stator winding is closed with the first rotor brush (4th with 5th), and the beginning of the second stator winding with the second rotor brush (7th with 6th). When switching the reverse to the second position, connect the 4th to 6th, and 7th to 5th.
The design of the electric drill speed regulator provides for the connection of a capacitor and the connection to the regulator of both wires coming from the socket. The diagram in the figure below, for a better understanding, is slightly simplified: there is no reversing device, the stator windings are not yet shown, to which the wires from the regulator are connected (see. Diagrams above).
In the case of the electric drill shown in the photo, only the two bottom contacts are used: the leftmost and rightmost contacts. There is no capacitor, and the second wire of the power cord connects directly to the stator winding.
Read about the principle of operation of the speed regulator in the article drill device.
Reducer. The presence of extraneous sounds, grinding and wedging of the cartridge indicates a malfunction of the gearbox or gearshift mechanism, if any. In this case, it is necessary to inspect all gears and bearings. If worn splines or broken teeth on the gears are found, then a complete replacement of these elements is necessary.
The bearings are checked for suitability after removing them from the armature axis or the drill body using special pullers. Holding the inner clip with two fingers, you need to scroll the outer clip. Irregular clip slip or “rustle”, when scrolling, they talk about the need to replace the bearing. A bearing not replaced in time will lead to jamming of the armature, or, in the best cases, the bearing will simply turn in the seat.
Replacing the drill chuck. The chuck is subject to wear, namely the clamping “sponges”, due to the ingress of dirt and abrasive residues of building materials. If the chuck is to be replaced, unscrew the retainer screw inside the chuck (left-hand thread) and unscrew it from the shaft.
In conclusion, I would like to add: when assembling the drill after repairing it, make sure that the wires are not pinched by the top cover. If everything is in order, the two halves will collapse without a gap. Otherwise, tightening the screws may flatten or bite the wires.

For example, remember that opening the housing can cause all parts and loose parts to simply fall out of the housing. Naturally, this should be avoided, because then it will be quite difficult to put the device together. To do this, you can smoothly lift the cover, noting the exact location of the spare parts on paper.
The button is repaired as follows:
- First, the clips for the casing are hooked, after which it is carefully pulled together;
- All rusted and darkened terminals are cleaned of carbon deposits, for which you can use alcohol or sandpaper;
- We reassemble the tool, making sure that all the parts of the device are in place, and we check the performance of the drill. if nothing has changed, we change the part;
- We fill the turnover regulator with a compound, and therefore, if the part fails, we simply replace it;
- A frequent breakdown is the erasure of the working layer under the rheostat. it is better not to repair it, just waste your time, it is better to buy a new one and replace it.
Many are interested in where to get such a scheme? First of all, it should come with the tool when you buy it, but if there is no scheme, or you have lost it, you will have to search the Internet. After all, only with its help you will be able to carry out the repair correctly, without errors. By the way, the speed control button and the reverse control button are located in different places, and therefore they will have to be checked separately.
How to connect the drill button yourself?
Despite the fact that this process is quite complicated, you can do all the work yourself, observing some important rules.
Possible tool malfunctions. we carry out repairs ourselves
If your tool has begun to work worse, or has completely ceased to perform its direct duties, it is time to diagnose malfunctions and try to cope with them. First, we check the wire for damage and voltage in the outlet, for which you can turn on any other device. a TV or a kettle.
If the voltage is less, you will have to replace the batteries with new ones. If the battery is working properly, the power supply is normal, look for problems in the hardware. The most common breakdowns are:
- Problems with engine operation;
- Wear of brushes;
- Problems with button operation.
Knowing how the electric drill button is connected, you can quickly solve the problem. In addition, a problem with the operation of the drill may also arise due to the dustiness of the tool, because the drill “takes” wood, brick, and other materials. This means that you should take care to clean the device after each use. this is the only way to reduce the risk of malfunction due to dirty tools. That is why after you have carried out repairs in the apartment, immediately clean the drill.
Drill button connection diagram. we fix the tool ourselves!
You can also repair a drill on your own, the main thing is to know the causes of breakdowns and methods of their “treatment”. Today we will talk about how the drill button connection diagram looks like, we will not ignore other malfunctions, thanks to which you will be the happy owner of a working tool.
Checking the electric motor: causes of breakdowns and repairs
There are several reasons for drill armature or stator breakage. First of all, this is the illiterate operation of the device. For example, many users simply overload the tool, carrying out work without interruption. This leads to the fact that the drill motor does not have time to “rest”. The second reason lies in poor wire harness, which are often found in cheap models. That is why breakdowns of cheap tools are much more common. In this case, repairs must be carried out using a specialized tool. And it will be better if you entrust this work to professional specialists.
However, if it was decided to carry out the repair on its own, you will certainly have a question. how to do everything right? As you already understood, an electric drill “suffers” from breakdowns of the armature and stator, and this can be checked by several signs, for example, when the tool suddenly sparks during operation. If there are no “bright” signs, you can use an ohmmeter.
The stator is changed like this:
- First, carefully disassemble the device case;
- We remove the wires and all internal parts;
- After finding out the reasons for the breakdown, we change the spare part to a new one, close the case again.
Drill button connection diagram. how to fix the problem?
Unfortunately, a tester will not be enough for you to check the performance of the tool, which is due to the fact that most of the buttons on the device are equipped with a smooth speed control, and therefore a conventional tester may give you incorrect data. In this case, you will need a special wiring diagram for the drill button. Often in tools, one wire is connected to a terminal, and therefore pressing the button at the same time will ring the terminals. In the event that the light comes on, everything is fine with the button, but if you notice a malfunction, it’s time to replace the button.
When replacing, keep in mind that the circuit can be either simple or with a reverse. Due to this, all work on replacing the button must be carried out exclusively according to the scheme, without adding anything “from oneself”. So, the part must be suitable in size and correspond to the power of the tool. At the same time, calculating power is a fairly simple exercise. We use the formula P = UI (taking into account that the power of the drill is 650 W), I = 2.94 A (650/220), which means that the button should be at 2.95 A.
How to replace brushes: work in a couple of minutes
But the drill may not work due to commonplace malfunctions. for example, because of the brushes inside the motor. This means that you cannot do without repairing brushes here, while this work is quite simple. you do not even need to have special knowledge and tools. To do this, we disassemble the device, remove the brush holders from it and change the parts that are broken. By the way, there are models, the body of which can not be disassembled. in them you just need to remove the special plugs through the installation window, after which we change the brushes.
As you can see, there are various breakdowns, many of which will be subject to you, others will be feasible only for specialists in service centers. And in order to reduce the risk of such breakdowns, you need to take care of your tool, clean it after work, check the condition of parts and brushes in order to replace them with new ones in time. However, if you see that you cannot handle it yourself, take the device to the workshop.
The main difference drills is that IE 1511 BE has an impact function, which makes it possible to work not only with wood or steel, but also with concrete (there is a special switch “drilling / drilling with impact”). When drilling several identical holes using IE 1511 BE, the key for fixing the speed may be useful.

With all kinds of attachments, the model can be easily turned into a saw, sharpener, scissors, jigsaw and other tools. The disadvantages of drills include the lack of reverse, which somewhat limits their versatility. Well, the advantage is that IE 1511 BE and IE 1211 E have a very low price compared to foreign models.
