How To Work With A Dummy Screwdriver
How to use a screwdriver? 5 basic rules
How to use a screwdriver correctly. Prepare it for work, install attachments, charge the battery, operate it safely and for a long time.
Is it possible to interfere with the solution with a screwdriver
It is possible, only you need a special attachment nozzle. And of course, neatness, so as not to accidentally fill the screwdriver with a solution.
Preparing the screwdriver for work
To bring this device into working condition it is necessary:
1. Pull it out of the case and inspect it for visible damage. Cracks on the case, etc. If found, use the tool is prohibited.
2. After inspection, dock the battery to it, and then make sure that there is enough charge to start work. If the battery slowly rotates the tool spindle, you need to remove the battery and put it on charge (see below how to recharge the battery), and connect another battery to the tool instead.
3. After making sure that the battery has gained a sufficient charge, the required nozzle is installed in the screwdriver, depending on the nature of the work (screwing in screws or drilling) and the size of the screws. We will tell you in detail about the installation of the nozzle further, but here we focus on the fact that for the safety of work during installation or replacement of the nozzle, the battery must be removed so as not to accidentally turn on the screwdriver.
4. Using the knobs on the instrument, select:
- Operating mode. Drilling, working with screws, in some models there is also an impact mode, for example, the Bosch GSR 180-LI.
- Rotation speed of the nozzle (if the model of the tool has several stages of rotation, for example, Makita DF347DWE); direction of rotation. For drilling and screwing screws clockwise, for unscrewing screws. Counterclockwise.
5. If you are going to drill to a certain depth, then in the models of screwdrivers where there are limiters on the drilling depth, you must set it.
Remember that the correct preparation of the instrument is the key to safe working with it.
How to store a screwdriver
Better separate from the battery. If you have a model with a nickel-cadmium battery, then before ending work and disconnecting the battery, it must be completely discharged. After removing the battery, it must be charged. Remember that Ni-Cd has a high self-discharge current, therefore, during long-term storage, it needs to be recharged periodically.
The tool consists of a housing containing a motor and a gear mechanism; chuck (clamp for replaceable drills); battery or cord to connect the device to the mains.
Features of operation
Incorrect operation and breakdowns may occur after switching the operating modes of the tool during the rotation of the chuck. To prevent this from happening, it is recommended to perform all operations only after turning off the screwdriver and completely stopping the engine.
It is also necessary to correctly select the torque of the device, taking into account the hardness of the material with which they work:
- Fiberboard and drywall. To screw the screws into these materials, use 1–4 modes.
- Hardwood. The control ring is moved to the maximum value.
Important! It is better to set a lower torque value than required. If you select an overestimated value after tightening the self-tapping screw, the screwdriver chuck will continue to rotate, and not stop as expected. The slot will be damaged.
You can use a screwdriver as a drill only for a short time. If you use a tool that is not designed for drilling for a long time, the motor may overheat and damage the device.
The most important indicators to look out for when buying are the rotational speed and power of the screwdriver.
The rotation speed affects the functionality of the device. For tightening or unscrewing fasteners, tools whose speed does not exceed 350 rpm are suitable. For drilling, you will need devices with a rotation speed greater than or equal to 1000 revolutions.
If you plan to purchase a cordless screwdriver, you should find out its type. The most common devices are those with lithium-ion cells and are characterized by a long service life. It is recommended to choose them if the device will be used frequently.
If work using a screwdriver is rare, a nickel-cadmium element is more suitable. They are cheaper, not as prone to self-discharge as lithium-ion ones. Mains powered devices are also suitable for purely home use.
Additional parameters that will make working with the screwdriver easier and more convenient:
- Illumination of the working area;
- A torque boost used to drown fastener heads;
- Impact mechanism;
- Increase in rotation speed.
Screwdriver design. Briefly about the tool diagram
The presented tool can be networked and cordless, and according to the type of work, a drill-screwdriver, a cordless screwdriver, a wrench and a screwdriver are distinguished. All of these tools work in the same way, but perform different functions.
If a conventional screwdriver works only with fasteners, then a drill driver can also drill holes. The wrench is designed for loosening or tightening bolts and nuts. The cordless screwdriver has a Phillips bit. In terms of power, this device is weak.
It is quite difficult to work without the presented tool, especially if you have to tighten a large number of self-tapping screws. Arrangement of a false ceiling, fastening insulation or drywall to the surface and many other actions. This is what a screwdriver is for.
How to use a screwdriver. Note for beginners
How to use a screwdriver. Sometimes an indispensable device in the economy and construction? It is a hand-held electric tool designed for loosening and tightening screws, screws or other types of similar products. We’ll talk about working with him below.
How to work with a screwdriver. Setup stage
The design of the screwdriver is quite simple. The plastic housing holds the motor and gears that drive the bit. The bit is located at the end of the device. On the case there is also a diode illumination, switches for speed and direction of movement, a tightening torque regulator, a toggle switch.
Principle of operation a screwdriver is also very simple. With the help of a motor, a shaft with a chuck is driven through a gearbox, in which the necessary nozzle is fixed. Now that you have learned how a screwdriver works, you can learn how to use it. First you need to provide a safe working environment. It is also advisable to check if the battery is well charged. If everything is in order, then you can get to work.
Before working with a screwdriver, you must insert the desired attachment into it. It is selected in accordance with the size of the head of the self-tapping screw or screw. To do this, remove the cartridge and sleeve from the device and insert the bit into the magnetic holder, which is then reinserted into the device and fixed in it.
The bit speed can now be adjusted. For this, a special regulator is provided on the device. It is advisable to carry out this stage before you started using the tool. To know how to work with a screwdriver correctly, you must first figure out how to change the direction of rotation of the spindle, for which there is also a switch.
What is a screwdriver? In fact, this is the same drill, but the screwdriver differs from it in that it has a lower rotation speed of the chuck and, at the same time, more torque.
Another difference is that if the rotational speed on the drill can change smoothly, then on the screwdriver, as a rule, “fixed” rotational speeds of the chuck are set. This is due to the “slip” function of the screwdriver chuck: when the screw is tightened, the chuck stops rotating, although the engine is still running. This function allows you not to tear off the slots and “drive” the screw inside.
Different types of speeds are designed for specific types of work and materials, as well as the “drilling” mode. Just like a drill, the screwdriver has a reverse function. The design features of the screwdriver allow them to perform a wide range of work: tightening and unscrewing screws and self-tapping screws, screws and nuts, drilling soft materials.
The designs of all screwdrivers are approximately the same. They are light enough and have a pistol grip designed for one-handed operation. The start key is designed in such a way as to adjust the rotation speed by pressing force.
An important element of a screwdriver is its power source. If the drills are produced in modifications both with a mains supply and in an autonomous (battery) version, then screwdrivers, due to the peculiarities of their application, are almost exclusively battery-powered. The battery is the heaviest and most expensive part of a screwdriver.
But whatever the battery, its capacity is limited by the weight of the tool. Therefore, even the most expensive models of screwdrivers are able to work continuously for no more than a few hours. Some manufacturers solve this problem by adding a second spare battery to the screwdriver kit. However, this significantly increases the cost of the instrument. The battery is being charged from a regular network. The charging speed again depends on the model and can be from 2-3 to 6 hours, although some models of screwdrivers provide a “quick” charge in 10-15 minutes.
How to work with a screwdriver
Working with a screwdriver is not difficult. In the jaws of the chuck, the nozzle necessary for operation is clamped (“bit”, or a wrench, or a drill), and, pressing the screwdriver with some effort, pressing the button rotates the chuck. If it is necessary to unscrew the screw or pull out the drill, the “reverse” is activated. When working, several rules should be observed:
- Charge it fully before using the screwdriver. At the same time, strictly follow the instructions for charging time. “overexposure” of the battery in the charger will reduce its service life.
- When working correctly select the mode of “screwing” or “drilling”. So you will protect the motor and gearbox of the screwdriver from damage. Remember that the screwdriver is not designed for drilling in stone or concrete.
- Try not to throw or drop the screwdriver. This is a rather fragile tool.
- Keep the screwdriver clean. Remember that fine dust and dirt particles act as an abrasive in the rubbing parts, and the elements of the screwdriver fail faster.
- Now you have a general idea of what a screwdriver is and how to work with a screwdriver. It’s time to pick up the instrument and create!
To work effectively with a screwdriver, you need to set the correct torque. When working with soft materials (drywall), switch it to the minimum mode, when drilling or screwing fasteners into hard surfaces. To the maximum. Before changing the mode, turn off the device and wait until the engine stops completely.
To prevent dust from flying into your eyes when drilling into the ceiling, you can put a plastic or paper cup on the drill. All dirt will collect in it, and it will be easier to control the progress of work.
Tips on how to use a screwdriver correctly
A screwdriver is a tool designed to tighten fasteners. With drills and special attachments, it can also be used to perform some other operations.

- Instrument care instructions
To polish the body, headlights of a car or other surface using a screwdriver, you need additional attachments. Polishing wheels. Circles made of cord or leather are used for preliminary cleaning. Felt tips are used for both cleaning and final polishing.
- The surface to be polished is washed from dirt and dust;
- Apply an abrasive compound to the polishing wheel;
- Consistently treat all areas with smooth movements without strong pressure.
In the process, the circle is periodically cleaned of paste residues using a clean rag. Polishing takes a long time, and the battery may be discharged. If the device becomes very hot, you need to turn it off and wait a while before resuming operation.
