How to use a screwdriver: step by step instructions

Each person at least once in his life made repairs at his home or performed work related to the repair of his apartment or summer cottage. Today, a screwdriver is an indispensable repair tool. When buying it, be sure to find out the power, equipment, as well as the warranty period for this power tool.

Screwdriver design

All types of drills are of the same type, including:

Cordless screwdriver diagram.

  • Split case;
  • Drill chuck;
  • Electrical and mechanical part.

The chuck is used to install the drill and connect it to the rotating shaft. It contains 3-4 jaws, between which the drill is placed. The cams move by rotating the adjusting sleeve. Anchoring, i.E. Reduction of the cams by turning the sleeve by hand or using a special key.

The electrical part consists of an electric motor, starting systems, reverse direction of rotation and engine speed control, as well as a power cord or battery. A collector single-phase electric motor is used as source of motion. A starting capacitor is installed to start the engine. The power supply to the motor is carried out through contact brushes fixed in holders.

The switch is usually designed as a start button. It is combined with an engine speed governor. The control circuit based on the transistor is made so that when the start button is pressed, the rotation speed of the motor armature increases.

The direction of rotation of the armature is reversed by changing the polarity at the input terminals. The reverse lever is brought to the body of the device.

The mechanical part of the screwdriver includes a gearbox, bearings and a force limiting mechanism. The gearbox provides the transmission of the rotational motion of the armature shaft to the main shaft, on which the chuck with the drill is mounted. The planetary gearbox contains a system of gears, satellites and carriers. The number of speed control steps depends on the number of satellites.

The force limiting mechanism is designed to optimize the load on the screw during tightening. When the screw is fully tightened, the resistance to rotation of the drill increases and the mechanism stops its movement. The whole mechanism can have up to 16 positions of force adjustment.

Using a screwdriver

Do not think that a screwdriver can enjoy, just to drill, twist and unscrew the screws. When repairing a car, you can unscrew and tighten nuts and bolts, grind with various surface attachments. Assembling furniture without using a screwdriver will take a lot of time. Hanging curtain rails or bookshelves with a screwdriver is much easier than running around with a screwdriver and putting in effort. So today the screwdriver has taken its place of honor among the most essential tools in the household.

How to attach a bit or drill

There are two ways to fix a drill or bit in a screwdriver. The first method is manual. The bit is inserted into the chuck and tightened by hand. The second method is to tighten the bit or drill with a rotating chuck, hold it with your other hand. It is very easy to check how you secured the bat. Try to tighten one self-tapping screw, and you will understand whether the bit is scrolling or not.

How to use a screwdriver correctly and safely

Working with this tool is intuitive. But you need to know certain subtleties that reduce the risk of injury and tool breakage. So, how to tighten the self-tapping screw with a screwdriver safely:

1. Carefully read the instructions BEFORE using the instrument for the first time, and not after something unpleasant has happened.

2. Correctly select the maximum torque at which the safety ratchet will operate and no force will be transmitted to the shaft. The tool is of course designed for maximum effort. But, firstly, constant work at the maximum reduces the service life. Secondly, the likelihood increases that the screwdriver can pull out of your hands. Thirdly, by learning how to correctly determine the maximum torque, you will reduce the likelihood of damage to the surfaces where you screw the screws. This is especially true for polished and fragile surfaces. For example, in the Bosch GSR 10.8 model, the maximum torque is 30 Nm, but you can also set 5 Nm.

3. Choose the right operating mode. It is not necessary to drill in the screwdriver mode, and even more so to tighten the screws in the drilling mode, where the speed is higher. The tool may simply be snatched from your hands.

4. Do not forget to control the direction of rotation. We twist the screw, the cartridge should rotate clockwise, we twist it against.

Above we talked about the rules of safe work relating directly to the screwdriver. Now about the general organization of work with this tool:

  • Wear safety goggles only and preferably with protective gloves, especially if you are drilling materials that can crack and fire sharp fragments.
  • Before drilling, make sure that there are no electrical cables and other utility lines in the area.
  • When tightening and loosening screws, as well as drilling small holes in diameter, do not lean on the screwdriver. The screw or drill bit may break and injure you.
  • Household and professional screwdriver models have different continuous operation times. In any case, it is! And it’s not worth bringing the instrument to a hot state.
  • After work, you need to disconnect the battery, remove the attachment, wipe the tool from dust.

Is it possible to cut a thread with a screwdriver

It is possible, but with reservations. Firstly, small diameters, up to 10 mm. Pipe thread ¾ in. You definitely won’t cut. Secondly, only internal. You will not install the die on the screwdriver. Third, skill is required. A slight misalignment and that’s it, either break the tap or just ruin the thread. Minimal cutting effort!

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 large self-discharge current, therefore, during long-term storage, it needs periodic recharging.

Do I need to lubricate the screwdriver

This tool has a gearbox and requires lubrication, such as ELF MULTI MOS. The frequency depends on the model and the intensity of use. The following signs indicate that your tool needs lubrication:

  • Unpleasant tearing sound;
  • The cartridge is difficult to rotate by hand.

You can lubricate with lithol, manol, silicone or Teflon grease.

Good to know

Is it possible to drill with a screwdriver

If you have a model that has two modes of operation, drilling and a screwdriver. Usually professional models have such capabilities, for example Makita DF347DWE. It is not necessary to use a model that does not have a drilling mode, the engine may burn out, since drilling requires higher revolutions to reduce the load.

Preparation for work

Before using a screwdriver, you need to choose a nozzle that fits in size to the head of the fastener. For installation in a tool with a keyless chuck, the nozzle is pushed between the cams, the sleeve is turned clockwise. To fix the nozzle in the device with a key cartridge, insert the key nozzle into the socket, turn it clockwise until it is fixed.

The device equipped with a rechargeable battery must be charged, and the mains-powered device must be plugged in.

To make sure that the screwdriver is working properly, first turn it on idle. See if the direction of rotation of the nozzle matches the direction of the thread of the fastener.

Features of operation

Incorrect operation and breakdowns can 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:

  1. Fiberboard and drywall. To screw the screws into these materials, use 14 modes.
  2. Hardwood. The regulator 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 will not stop as expected. The slot will be damaged.

You can use a screwdriver as a drill only for a short time. Continuous loading of a tool that is not designed for drilling may overheat the motor, causing damage to the device.

Types of screwdriver

Modern devices are divided into subspecies, which differ in functionality.

  • Screwdrivers, with which you can only tighten fasteners;
  • Wrenches used to tighten hexagons;
  • Cordless screwdrivers least powerful basic tools
  • Screwdrivers, also used for drilling holes.

By the type of power supply, the devices can be rechargeable or powered from the mains. The first ones are considered more convenient, since they allow you to work away from outlets, including on the street.

Screwdrivers can be with a key chuck for fastening the drill or a quick-release.

Tool selection

The most important indicators to look for when buying, 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 whose rotation speed is 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 with lithium-ion cells 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 sink the fastener heads;
  • Impact mechanism;
  • Increase in rotation speed.

Design

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 network.

Screwing and tightening fasteners

Instructions for using the device are simple:

  1. Insert the tip of the nozzle into the slot of a self-tapping screw or screw, turn on the device.
  2. To increase or decrease the tightening speed, increase or decrease the pressure on the start button.
  3. When the self-tapping screw is tightened, the force limiting mechanism will automatically work, after which the work will stop.
  4. To unscrew the screw, the nozzle is placed in the slot, after setting the lever for the direction of rotation of the nozzle in the opposite direction.

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 torque regulator, a toggle switch.

The principle of operation of the 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 start 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, you need to remove the cartridge and the 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 start 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.

The design of the screwdriver 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 these tools have the same principle of operation, 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, that’s what a screwdriver is for.

How to use a screwdriver for beginners on a note

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 use a screwdriver accuracy and safety

After the settings are made, you can start using the tool. To do this, the battery is connected to the device and the necessary work is done. Knowing how to use a screwdriver correctly, you can avoid unwanted actions when handling the device, which will increase its uninterrupted service life.

It is impossible to adjust the frequency and direction of rotation of the nozzle if the device is on and running. Protect the device from moisture penetration into it. The room in which the device will be used must be well lit, and the power supply network stable, without drops.

Do not touch the device to grounded objects, otherwise the user may get an electric shock. Do not use the device continuously for a long time, otherwise it will simply burn out. It is advisable to work only with a working device and in special protective clothing.

Choice of screwdrivers

Modern screwdriver designs have several modifications, determined by the purpose. The following main types of devices can be distinguished:

  • Screwdriver:
  • Drill screwdriver;
  • Wrench;
  • Cordless screwdriver.

If a conventional apparatus is designed only for tightening fasteners, then a drill-screwdriver combines the functions of drilling and tightening fasteners by expanding the speed range. The smallest device is a cordless screwdriver. The wrench is equipped with an attachment for tightening nuts and other hexagons.

By the type of power supply, screwdrivers can be divided into batteries and mains powered. Cordless devices have a great advantage in terms of mobility. They are usually equipped with nickel-cadmium and lithium-ion cells. By the drill fastening mechanism, one can distinguish screwdrivers with keyless chuck, and screwdrivers with key chucks.

Power and rotation speed are important parameters of the apparatus. Power can be expressed in soft and hard torque functional parameters. The soft torque determines the maximum permissible load in the tightening mode and the hard torque in the drilling mode. For ordinary screwdrivers, the first parameter is most important. So, with a torque of 30 Nm, the length of the screw to be screwed is limited to 70 mm, and at 40 Nm it increases to 100 mm, etc.

The rotation speed determines the purpose of the apparatus. When using it only in the mode of twisting or unscrewing screws, the speed is set to 350 rpm. If the machine is used in drill mode, the speed must be at least 1000 rpm.

Removable battery device diagram.

When choosing a cordless screwdriver, you should consider some of the characteristics of batteries. Modern imported devices are most often equipped with lithium-ion cells. Such batteries have a number of advantages, incl. Sufficiently long service life. However, they tend to self-discharge, i.E. Discharged during storage. Screwdrivers with these batteries are great when they are used frequently. If they are rarely operated, it is advisable to use devices with nickel-cadmium elements, which are less susceptible to self-discharge and are much cheaper. Any batteries must be selected according to their capacity. The higher this indicator, the better the element is. If the screwdrivers will be used at home, where there is access to sockets, then it is better to choose a device powered from the mains.

When choosing an expensive high-quality screwdriver, you should pay attention to additional functions that will expand the capabilities of the device. These include:

  • Introduction to the design of the percussion mechanism, which will help when unscrewing the socket heads;
  • Providing an impulse to increase the torque, which is useful when drowning the screw head;
  • The possibility of increasing the rotation speed up to 1000 rpm;
  • Illumination of the working area.

When choosing a cheap but sufficient screwdriver for home conditions, you can choose a device with a torque of 30-35 Nm and a mains supply or with a nickel-cadmium battery with a capacity of about 2 A / h.

The work of the screwdriver in the tightening mode

Diagram of installing a bit in a screwdriver.

Before starting work, it is necessary to select the desired nozzle (drill) according to the size of the screw head and the shape of the slots (straight or cross). The nozzle is installed in the center between the set cams and is fixed in the chuck by rotating the sleeve clockwise by hand. If a key type chuck is installed, the key is inserted into the socket on the chuck and rotated clockwise until the attachment is secured.

The tip of the nozzle is placed in the slot of the screw, the start button is pressed.

By increasing the pressure applied by the finger to the trigger, the optimum tightening speed is achieved. When the screw is fully screwed in, the force limiting mechanism is triggered and the drill stops. The finger is removed from the button. The screw tightening process is complete. Unscrewing the screw is done in the same way, but with the direction lever in the opposite position. The optimal value of the torque (power) when screwing the screw into hard and durable materials is set by rotating the torque regulator ring, on which graduations are applied corresponding to different powers.

How to use a screwdriver correctly?

The types of drills are a hammer drill and a screwdriver. If you need to tighten the fasteners, then you should learn how to use the screwdriver. All these devices are very similar to each other, but differ in purpose and have their own specific features.

The main purpose of the screwdriver is screwdriving.

This type of drill is designed for fixing screws. Recently, many people have recognized the convenience and usefulness of the apparatus. Those who have not yet had time to get to know him are wondering how to use a screwdriver correctly.

The correct use of a screwdriver can be divided into a number of steps:

  • Choice of apparatus;
  • Familiarity with its design;
  • Operation and maintenance of the device.

Maintenance of the screwdriver

When working with a screwdriver, use only the attachments included in the kit.

The use of a screwdriver implies proper maintenance. First of all, it cannot be used to drill holes for a long time. For this you need to use a drill. The use of a screwdriver as a drill is allowed only in a short-term mode.

When tightening the screws, use only the attachments supplied with this unit. Do not install damaged attachments (drills). All rotating elements, as well as the inside of the chuck, must be lubricated periodically.

Check the charging of the batteries in a timely manner. To eliminate the memory effect of the battery, it is recommended to completely discharge it before recharging it. Store the device only in a dry place. During prolonged operation, the possibility of engine overheating should be monitored. Periodically, the device should be turned off until complete cooling.

When working with a screwdriver, you should have the following tools in stock:

  • Screwdriver;
  • Pliers;
  • Brush;
  • Brush;
  • Vice;
  • Calipers.

The screwdriver has a fairly simple design. Anyone can use it. But in order to correctly solve the question of how to use a screwdriver, certain rules should be followed.
