How to use a screwdriver drill. Instructions

The cordless drill / screwdriver is a must-have tool for any home craftsman. Its versatility allows you to easily perform work both on tightening and unscrewing various types of fasteners (screws, self-tapping screws, screws), as well as drilling holes.

Let’s take a look at how a drill-driver works and understand the attachments and accessories.

Setting the torque

The drill has an adjusting ring for setting the torque, on which its values ​​are applied.

This is necessary in order to set the most appropriate value when working with materials with different hardness.

For example, for screwing screws into drywall (with a little effort), a range of values ​​of 2-4 is suitable, and for hard wood, the torque can be set to the maximum number on the ring.

This adjustment helps to avoid quick damage to the fastener splines.

This allows you to stop the operation of the tool in time when the self-tapping screw or screw is fully tightened.

Bits. Nozzles

The screwdriver comes with several types of bits with different shapes of the working edge.

Bits with a straight edge are designed to work with fasteners that have one slot (slot). A suitable bit is selected depending on its length and depth.

Similarly, the shape of the cross-shaped bit is selected. Here the width of the slot and the dimensions of the fastener head itself are taken into account. For reliable operation, the edge of the bit must fit tightly into the splines, otherwise there is a possibility of “licking” the edges of the splines.

To attach the bit to the chuck, a special attachment with a magnetized holder is used, which prevents the structure from disintegrating and reliably holds the bit in a variety of positions.

To fix the bit with the bat, you need to unscrew the movable part of the chuck.

Insert the nozzle and screw in the cartridge until it stops.

There are also very convenient double-sided bits that can be fixed in the chuck without a nozzle.

Good to know

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.

Do I need to lubricate the screwdriver

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

  • Unpleasant “hysterical” sound;
  • It is difficult to rotate the cartridge by hand.

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

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.

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.

Features and varieties of the instrument

The screwdriver can be battery operated or mains powered. The type of operation of the instrument may be different, in this regard, it is customary to distinguish the following varieties of it:

  • Drill screwdriver;
  • Wrench;
  • Cordless screwdriver;
  • An ordinary screwdriver.

According to the type of work, screwdrivers are divided into several types: screwdriver, drill-screwdriver, wrench and cordless screwdriver.

The principles of operation of each of these tools are similar, the difference between them lies in the functions for which they are intended.

The drill driver additionally allows you to drill a hole, and the usual one is designed only for working with fasteners. The nutrunner is designed to work with bolts and nuts, and the cordless screwdriver is designed to tighten and unscrew Phillips head fasteners. The last device has the lowest power of all.

A screwdriver is indispensable if you need to make a suspended ceiling, mount drywall or sheet insulation. The absence of this device greatly complicates the work, during which it is necessary to tighten a lot of self-tapping screws or other fasteners. And in everyday life, when you need to screw in or unscrew 1 screw, doing this with a screwdriver is much more convenient and faster.

Not every owner knows how to use a screwdriver, despite the high demand for this tool in the household. There is nothing difficult in working with a screwdriver, however, in order to get the best result from its use, it is recommended to adhere to certain rules.

Device setup and design features

The construction of the tool is quite simple. The plastic housing contains a motor and a gear mechanism that drives a bit located at the end of the device. The design also provides for the presence of a toggle switch, a switch for direction and speed of movement, a diode backlight, a tightening torque regulator.

Before working with a screwdriver, it is necessary to select such a nozzle for it, which will correspond to the size of the head of a self-tapping screw or screw.

The principle of the tool is as simple as its design. The nozzle, fixed in the chuck, is set in motion by means of a shaft, which begins to move from the operation of the engine through the gearbox. Before starting work with a screwdriver, you need to check whether the battery is charged and whether the attachment is installed, which is necessary.

To install the required nozzle, you need to select it according to the size of the head of the fastener and insert it into the magnetic holder of the chuck. For this, the cartridge and the sleeve must be removed from the device. After installing the required bit, the chuck is reattached to the tool body.

Next, you need to set the optimal bit speed. This can be done with a dedicated regulator. The required mode is set on the device being used prior to its operation. You can also switch the direction of movement of the bit.

Before using the screwdriver, you need to adjust the screwing depth of the fastener. Over time, it may become necessary to replace the magnetic holder in the chuck. To replace the magnetic holder, the cartridge and the coupling, the magnetic holder are removed, and another is installed in its place. After that, the cartridge with the coupling is installed back into the screwdriver body.

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 of the finger on 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 established by rotating the torque regulator ring, on which graduations are applied corresponding to different powers.

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 device is designed only for tightening fasteners, then a drill-driver combines the functions of drilling and tightening fasteners by expanding the speed range. The smallest device is the cordless screwdriver. The wrench is equipped with a nozzle 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 a keyless chuck, and screwdrivers with key chucks.

Power and rotation speed are important parameters of the apparatus. Power can be expressed in functional parameters. Soft and hard torque. The soft torque determines the maximum permissible load in the twisting 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 the screws, the speed is set to 350 rpm. If the machine is used in drill mode, the speed should be at least 1000 rpm.

When choosing cordless screwdrivers, you should consider some of the characteristics of batteries. Modern imported devices are usually 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 used frequently. If they are rarely operated, then 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 by 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.
