Using a drill as an electric screwdriver: How to use a drill inappropriately: 4 tiphacks
Electric screwdriver drill. An indispensable tool in the household. But not everyone knows how to use it. And the large number of different settings can be confusing for a beginner. This article will help you overcome the fear of drilling.
DIRECTION OF ROTATION
There is a button that goes through the drill, looking out to the right and left. This is the switch for the direction of rotation of the drill. Clockwise, we drill or screw in screws and bolts. Counterclockwise. Helping the drill come out of the hole or unscrewing screws. When the switch is in the middle, the drill locks up. So if the battery is charged and the drill does not work, check to see if the switch is facing left or right.
SCREWS CAN BE DRIVEN WITH VARYING DEGREES OF TORQUE
Most screwdrivers have a scale that has numbers from 1 to 20 written on the “collar” of the chuck. This is the torque, i.E. The force with which the chuck is turned. The higher the value, the more resistance the electric screwdriver can overcome. If you don’t know what to put in, start with a lower number. Small or medium torque is usually sufficient for less demanding tasks, such as driving a short screw into soft wood. If it doesn’t work, increase the torque.
You might find it useful
Some screwdrivers have an automatic sensor that thinks for you. It senses when it needs more torque.
N.B. Set value between 1 and 20 only if it is necessary to drive in or drive out a screw. If you have to drill, read the following paragraph.
DRILL AND HAMMER ICONS
On the same “collar” there are pictures of a drill and sometimes a hammer (if you have an impact drill). The drill icon should be set during drilling, then the chuck will not spin, regardless of resistance. And if you’re drilling a concrete wall, set the hammer to activate the impact mechanism.
N.B. Do not use these modes for tightening screws! The chuck will not twist if there is a lot of resistance. At some point it can get stuck and the drill will spin with your hand instead of the chuck. This can cause injury.
There is a speed switch on the top surface of the drill. Usually there are two speeds (sometimes there are three). If number 1 is set, the drill twists harder but slower. Suitable for drilling big and deep holes, tightening difficult screws, or for starting to unscrew the screw out of a wooden item, i.E. Loosen it.
If number 2 is selected the drill is slower but fast. Ideal for fast unscrewing of screws that have loosened a little, for drilling shallow and small holes in soft material.
N.B. Do not touch the speed switch until the tool has come to a complete stop or you could break it.
Also called the start button. Here it’s easy: Press and the drill works, release. It does not work. There is a BUT. On some drills the speed depends on how hard you squeeze the trigger.
Removable battery located in the drill housing. Many batteries have an indicator light that tells you how much charge is left. To turn it on, click on the battery icon. Make sure the battery is fully charged before you start working.
HOW TO CHANGE DRILLS AND BITS
The chuck is the part of the drill that holds the drills and bits. Attachments like screwdrivers for tightening screws. They are clamped either manually with a special wrench or automatically without a wrench (quick-clamp chuck).
To clamp the drill bit or nozzle in a keyless drill, hold the chuck with one hand and slowly squeeze the trigger with the other hand (the rotation must be clockwise). To pull out the drill, do the same thing, only counterclockwise.
Make sure drill bit is firmly seated in chuck. Pull the trigger and watch it twist. If the drill bit is not positioned correctly, you will see that it wobbles, wobbles, deflects.
TYPES OF HANDS
Regular twist drills are versatile tools for drilling wood, metal, plastic and other materials. Concrete, brick and stone require particularly tough drill bits with a carbide tip. Feather drills, similar to paddle drills, are designed for large diameter holes. And there’s a special mixer attachment for stirring paint and other mortars.
You might also need
In addition to drills, there are also drill bits. They turn your tool into an electric screwdriver (aka electric screwdriver). The tips of these bits come in a variety of shapes and fit all kinds of screws, screws, nuts, and more. Some bits fit directly into a chuck. But more often you need a special magnetic adapter that is inserted in the drill and the bits are then magnetized to it.
MAGNETIC DRILL BIT AND BIT HOLDER
Today’s cordless drills have a magnet. You can attach the bits to it so they’re always at hand. This is very handy!
HOW TO DRILL
Hold the drill with your hand like a pistol and place your index finger on the trigger. Put your other hand around the body of the tool or put it on top of the tool. Hold your drill at right angles to the surface you want to drill. Then pull the trigger and apply gentle pressure to the tool to help the drill enter the material.
If you are drilling into a piece of wood, periodically pull out the drill bit and remove the chips.
Before you drill a big hole in the wood, you need to make a small hole. Otherwise, the wood might crack or split. Take a thin drill bit and drill a pilot hole with it. Its depth should coincide with the future end hole you need. Then insert the main drill bit and drill the hole using the pilot drill bit as a guide.
THE PILOT HOLES FOR THE SELF-TAPPING SCREWS
If you are working with hard wood or other hard materials, make a pilot hole first before driving a screw straight into it. To do this, take a drill bit that is slightly smaller than the self-tapping screw. To correctly size it, put the drill bit against the screw: the drill bit should overlap the body of the screw, but its thread should peek out at the top and bottom.
Why choose a cordless electric screwdriver: the main types of devices, rules of operation
Before buying a product, it is first necessary to determine the principal objectives that need to be achieved with an electric screwdriver in industrial or domestic applications. The main areas where the tool is used:
BIELMEIER 4V (RECHARGABLE ELECTRIC SCREW DRIVER
Select the device should be based on the purposes it is to perform
- Assembly or disassembly of fasteners;
- Tightening self-tapping screws, dowels, anchors or other elements more securely;
- Making holes in soft or hard materials;
- Preparation of mortars that require mixing.

Electric screwdriver in most cases is used for several tasks at once. Therefore, to begin with, we should examine the technical characteristics of an electric screwdriver. Depending on the application, tools are divided into 2 large groups:
The distinctive feature of household tools is their low power and short motor life. They are considered suitable for working with soft material:
They are divided into two groups. Professional screwdrivers and domestic screwdrivers
Important! Household screwdrivers are not designed for extended use. The main areas are assembling furniture, installing locks, fixing shelves, blinds, etc. Д.
Professional tools are designed to last longer than household tools. So, it is possible to operate an electric screwdriver daily for 5-8 hours with short breaks and do not fear that the device will break down or overheat. The tool is also used for twisting and screwing, and most models are equipped with a function of drilling various materials:
It should be understood that concrete work requires the purchase of cordless impact screwdrivers designed for hard materials.
Household screwdrivers are low-powered, and not designed for long-term use

What is the torque, impact and bits for your electric screwdriver?
Is it worth it to buy a powerful device or it is better to save money, whether to use a hammer or not, why to work with big drill bits at all?? Now we will tell you how to choose a cordless electric screwdriver for the home, relying on its characteristics and numbers that are written in the technical data sheet of this product.
“Why does a cordless drill have an accordion” or why does it have a kick function?? This question is asked by many, because there are always doubts about the relevance of loading a light hand-held tool with such technology. You pay about 1000 extra and you already have an electric impact screwdriver. It’s heavier, more massive, but it can’t make a lot of holes in concrete anyway, it needs a peorator, and to deprive yourself of constant comfort for a couple of holes is dubious pleasure.
Now for the torque. This is already important. 14-24 Nm is suitable for installation of light structures of drywall, plywood, OSB boards. If you have to work with thick boards, drill ceramic or concrete with a crown, it is better to get 36 Nm. If in doubt which is a good electric screwdriver and which is not, judge by the torque, it decides a lot. If it is more than 36 Nm then it is good for metal drilling and work with big drill bits.
Now a little bit about the diameter of the drills. Even if you bought a cordless electric screwdriver with the characteristics of a power drill, it will not replace it. It is not necessary to take the tools with torque of 80-120 Nm in hope to work with 10-12 mm metal drill bits. It will not pull anyway, besides, its cost will be 5 times more than simple cordless electric screwdriver and simple wall drill put together. It’s worth it?
As for rotations per minute. It is not so important, because standard 1400 rpm is enough for everybody, and professional models that go for 2400 and more. It is already overkill and it is necessary only in very specific situations, when the tool is used for non-standard solutions.
We told you what cordless drill-electric screwdriver to choose and what characteristics you should look at. But there is one very important point. Where is the assurance that the figures are correct? Many Chinese and even European manufacturers inflate the data to make the tool more attractive to the consumer. As a result, you read a lot of literature, ask a neighbor or a friend how to choose a cordless drill, buy equipment with KM 80 Nm, impact, cool battery, high RPM, and you get a useless piece of iron. For this purpose it is necessary to get acquainted with manufacturers.
Battery capacity of power tools
With cordless power tools, power depends on the parameters of the existing electric motor. As for cordless models, you need to consider parameters of the entire electromechanical complex. The voltage (V or volts) is related to the power of the tool and depends directly, above all, on the number of cells in the removable battery pack. In this case the power of the tool will increase with increasing voltages of the battery pack with which it is completed. In practice it means that the harder the job is, the more power is needed and the more battery cells you need to have in your battery pack. But more batteries increase the weight of the tool and the extra capacity is worth the extra cost. Hence the first rule: choose the right tool for the job. So, for household purposes, a drill with a 12-14.4V battery is quite enough. At the same time, there are models with 36 volts, which is obviously too powerful to screw in a furniture screwdriver or unscrew a dowel nail.
But it would be too easy if the choice of power consisted only in matching the battery pack to the voltage. And while this is often the case, you should also pay attention to another important parameter, the battery capacity, expressed in ampere hours (Ah). Low capacity will quickly drain the battery and the tool will lose its power. Capacity can be represented by each element as well as the entire battery pack. This means that battery packs can have the same capacity at different voltages. When the voltage is taken into account, the capacity allows you to estimate how long the tool will last from charge to charge. Batteries for domestic drills and impact drills usually have a capacity of 1.2 to 1.5 Ah. A battery pack with a higher capacity will therefore provide longer tool life if the same voltage is used.
Direction of rotation of the chuck
In the design of the drill. The electric screwdriver has a pusher-type switch that can be used to change the direction of the chuck rotation for screwing or unscrewing fasteners.
On both sides of the tool there is a directional marking next to this switch. You can reverse the screwdriver by pushing the switch.
Remember that the direction of rotation can only be reversed when the motor is at a complete standstill.
The switch in the middle position locks the tool in place. It is used for changing drill bits or drills.
The chuck of the drill/driver can be replaced if needed. Please note that the drill chuck is fastened with the left-hand threaded screw and therefore should be unscrewed clockwise.
This screw can be accessed via the front of the chuck.
The tool kit also includes a set of drills of different diameters. All are designed for relatively soft materials.
The drill bits are clamped in the chuck in the same way as with the bit.(see fluid and solvents in the tool). Photo above)
Simply wipe housing with damp cloth and dry it off, do not use household chemicals or solvents.
No freezing of the battery pack.
How to correctly use an electric screwdriver?
It is not uncommon at home or during repairs to have a situation where an electric screwdriver is just necessary. This hand-held power tool is designed for tightening and unscrewing various fasteners (screws, self-tapping screws, etc.).).
How to use an electric screwdriver, not every owner knows, despite the high demand for this tool at home. There is nothing complicated in working with an electric screwdriver, but to get the best result from its use it is recommended to adhere to certain rules.
Features and types of the tool
Electric screwdrivers can be cordless or mains powered. The type of work of the tool can be different, in connection with this, it is customary to allocate such its varieties:
According to the type of work screwdrivers are divided into several types: an electric screwdriver, a drill-electric screwdriver, nutrunner 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.
An electric screwdriver drill additionally allows you to drill a hole, and a regular screwdriver is designed only to work with fasteners. A screwdriver is designed to work with bolts and nuts, and a cordless screwdriver is for tightening and unscrewing fasteners with Phillips-heads. The last device has the lowest power of all.
An electric screwdriver is indispensable if it is necessary to make a suspended ceiling, mount plasterboard or sheet insulation. The absence of this device greatly complicates the work, during which it is necessary to screw many self-tapping screws or other fasteners. And in everyday life, when you need to screw in or unscrew 1 screw, it is much more convenient and faster to do it with an electric screwdriver.
Setting the tool and design features
The design of the tool is quite simple. The plastic housing contains the motor and the gear mechanism that drives the bit located on the end of the device. It is also designed with a toggle switch, direction switch, speed switch, LED backlight, and torque controller.
Before operating an electric screwdriver, it is necessary to choose such a socket that corresponds to the size of the head of a self-tapping screw or a screw.
The principle of operation is as simple as the construction of the tool. The nozzle, fixed in a chuck, is driven by the shaft, which starts to move from the motor through a gearbox. Before you start working with an electric screwdriver, it is necessary to check whether the battery is charged and whether the right bit is installed.
To install the required nozzle you need to match it to the size of the head of the fastener and insert it into the magnetic holder of the chuck. For this purpose, the chuck and socket must be removed from the device. After positioning the bit, the chuck is reattached to the tool body.
Next, the optimum bit speed must be set. This can be done with a special regulator. The required mode is set on the device in use before operation. The direction of rotation of the bit can also be switched.
Before the electric screwdriver can be used, the driving depth of the fastener must be adjusted. It is sometimes necessary to replace the magnetic holder in the chuck over time. To change the magnetic holder, the chuck and sleeve are removed, the magnetic holder is replaced with a new one. Then put the chuck and socket back in the casing of the electric screwdriver.
Safety precautions for using the electric screwdriver
Use the tool only after all necessary adjustments have been made. To start working, the tool must be plugged into the mains or connected to the battery. After that you can switch the electric screwdriver on and do what it is intended for, i.E. Tighten or unscrew fasteners. Compliance with the rules of operation extends the life of the tool and ensures better results in a shorter time.
It is forbidden to adjust the movement of the bit while the electric screwdriver is operating. Make sure that the tool or its housing does not get wet. It is highly recommended that the unit should only be operated in sufficient light. Also, if the tool is mains-powered, there must be no voltage fluctuations in the electrical supply.
Never allow the electric screwdriver to come into contact with earthed objects. If this were to happen, the handyman could receive an electric shock. Avoid overheating of the device due to prolonged nonstop work. If the power tool is not allowed to rest, it can burn out. The instruction manual of the tool should be thoroughly read before operating it. You should not work with an electric screwdriver if any malfunctions are detected in it.
It is advisable to wear special protective clothing while working.
Thus, despite the simplicity of the design and principle of operation of the device, not every beginner knows how to use the electric screwdriver correctly in order to extend its service life. Observance of some simple rules of operation will ensure the safety of the master, the safety of the device and the excellent quality of the result.
What is Voltage?
The voltage indicates the amount of energy the battery produces under ideal conditions. In other words, it is the maximum energy potential of the battery, which is the basis for generating electric current. Higher-voltage batteries work with more powerful cordless tools and provide the energy needed for efficient high-torque operation. Understanding how the difference in battery voltage affects the performance of a cordless tool will help you choose the right model.
Drills with higher voltages are more efficient in harsh conditions and tend to cost a bit more. The simpler the job, the less power needed. That’s why many craftsmen prefer to use 20-volt models for demanding tasks instead of their smaller 12-volt counterparts: the higher voltage creates more torque. It’s kind of obvious. The more, the better. But in practice, many home repair jobs don’t require the same amount of power as large-scale construction projects, so you simply won’t need a 20-volt model. Higher voltage equals more torque and higher weight, which is not always appropriate. At home it is most convenient to use compact and lightweight tools for 12 and 14 volts.
In addition to the direct purpose of an electric screwdriver used to perform various non-traditional operations. These include the following types of work:
- Polishing cars and their headlights;
- Stirring of small amounts of various construction mixtures and paints;
- Drilling holes in the ice (for this purpose, the tool is equipped with a special attachment. A drill);
- Tying rebar;
- Mowing the grass (for this purpose the device is converted into a trimmer for grass or a lawnmower, or simply inserted into the chuck the nozzle with blades);
- Shredding of soft grass or thin branches (for this purpose, a garden chopper is created on the basis of a drill. Electric screwdriver);
- Sanding surfaces;
- Material cutting;
- Wire twisting.
This is an incomplete list of non-traditional works, performed using cordless or networked models of electric screwdrivers. Never stand still when it comes to invention. Almost every specialist has options for atypical work for this power tool.
An electric screwdriver can be used to restore a car to its original color and shine. To polish a car, the following varieties of nozzles are used:
- Leather or cloth circles, with their help perform the initial cleaning of surfaces;
- Felted. They are used for initial processing and finishing polishing (nozzles made of sheepskin are suitable);
- Foam pad.
Together with tools, polishing pastes and polishes are also used. They come in these types:
Using similar tools, headlight polishing is also carried out.
Knitting reinforcement bars with steel wire is very common in the construction industry in the construction of reinforced concrete (monolithic) structures, such as foundations, houses. Even if there is a small amount of work to be done, it is quite unproductive to work with a hand hook or pliers. Much faster will help to knit fittings cordless or cordless electric screwdriver, equipped with an attachment in the form of a hook. In this case, the power rating of the tool is not particularly important.
Twisting the stripped ends of wires, for example, in junction boxes is also quite a chore. Speed up the process by using an electric screwdriver with a special attachment. How to do the twist, shown in the video below:
