How to get the bit out of an electric screwdriver
What is an electric screwdriver? It is basically the same drill, but an electric screwdriver differs from it in that it has the slowest chuck rotation speed and, immediately, a higher torque.
Another difference is that while the speed of rotation on a drill changes smoothly, an electric screwdriver usually has “fixed” chuck rotation speeds. This is caused by the screwdriver’s “slipping” chuck function: when the screwdriver is tightened, the chuck stops turning although the engine is still running. This feature prevents the slots from being torn or even from “driving” the screwdriver inward.
Different types of speeds are designed for specific jobs and materials, as well as a “drilling” mode. Just like a drill, an electric screwdriver has a reverse function. Features design electric wrench allows them to do a wide range of works: screwing and unscrewing screws and screws, screws and nuts, drilling of soft materials.
The use of an electric screwdriver, for example, in the manufacture of drywall partition walls or when assembling furniture, increases the speed of work with a good return. That’s why the electric screwdriver is really considered the most common tool in the kit of any craftsman.
The design of all screwdrivers is approximately the same. They are quite light and have a “pistol grip” designed for one-handed operation.

The start button is designed in such a way to regulate the rotation speed by force of pressure.
The basic element of an electric screwdriver is the source of its power. If drills are available both in modifications with power from the network, and in an autonomous (battery) variant, then the screwdrivers, because of the peculiarities of implementation, are practically only battery-operated. The battery is the most voluminous and expensive part of an electric screwdriver.
Household models of electric screwdrivers are usually equipped with nickel-cadmium batteries (designated as “Ni-Cd”), and the more expensive professionals. with lithium-ion (“Li-Ion”) batteries. Their difference is that the nickel-cadmium ones have the shortest service life (about 1000 recharges), also have one unpleasant feature: if the battery is discharged little, at the next charge its capacity is miniaturized.
But whatever the battery, its capacity is limited by the weight of the tool. That is why even the most expensive screwdriver models are able to work without interruption for less than some time. Some domestic manufacturers solve this problem by the introduction of the electric screwdriver set second spare battery. But, this significantly increases the price of the tool. The battery is charged from the ordinary mains. Charging speed again depends on the model and is from 2-3 to 6 hours, although in some models of screwdrivers provides a “fast” charging for 10-15 minutes.
Rules of operation
It is not difficult to work with an electric screwdriver. In the chuck jaws clamp the necessary accessory for work (“bit”, or a wrench, or drill), and, with some effort pushing on the electric screwdriver, pressing a button makes the chuck rotate. If you need to unscrew a screwdriver or remove a drill bit, you turn it in “reverse. A few rules should be followed while working:
Easy!! How to remove a stuck bit from an impact driver (Ryobi, Dewalt, Makita, Ridgid, Milwaukee)
- In advance of working with an electric screwdriver, charge it one hundred percent. For all this, strictly follow the requirements of the annotation in the charging time. “overcharging” the battery in the charger reduces its service life.
- During the work correctly choose the mode “screwing” or “drilling”. so you protect the engine and gearbox of the electric screwdriver from damage.
Remember that an electric screwdriver is not designed to perform drills stone or otherwise concrete.

Quite ordinary electric screwdriver for independent use, the main thing which possesses the game slots device universal lithium battery rechargeable battery, suitable for electric jigsaw and delta grinder.
The electric screwdriver together with battery weighs 1.3kg. In other words, it is not heavy, but not light. The biggest torque at the same time is 46Nm, which is very good.
The rpm is adjusted like most other wrenches and drills. with a button. Also by default, next to the chuck rotation direction switch is placed.
The electric screwdriver has a standard quick-action three-jaw chuck. The biggest spindle cross-section of the drill bit that is possible to clamp in this chuck. 10mm.
The manufacturer advises not to use this electric screwdriver, to perform drilling of huge holes: in steel than simply than 10 mm in wood over 35mm.
To fix the bit or another drill bit in the quick-action chuck of an electric screwdriver, it is enough to fix the chuck by hand and turn on the electric screwdriver at high RPM.
How to work with an electric screwdriver
What to extract the drill or bit, you need to switch the electric screwdriver in reverse, lock the chuck and turn on the electric screwdriver: cams will unclench and release the drill as it is also called bit.
The torque limiting clutch, which has become the benchmark in screwdrivers. On the top of the housing, in front of the chuck there is an arrow that indicates the number. The more the number, the more torque the clutch can withstand without tripping. In total, the clutch has 10 positions with different torque settings, plus a drill mode. Working in drill mode? which is marked “DRILL”, the torque limitation clutch is disengaged. And with an electric screwdriver there is already the option of drilling.
This screwdriver has two Spectra speeds from 0. 400 rpm and from 0. 1340 rpm. Speed of course switch the reddish motor switch in the top of the electric screwdriver, in the “back” position, the electric screwdriver operates at first. low speed. If the slider is moved forward, it has a second speed. Today you can see the speed number in the window next to the switch.
A comfortable feature for the newcomer. the direction indicator: two triangles at the top of the device, will help find which way the electric screwdriver works: arrow forward means that the chuck turns clockwise and respectively screws screwdriver, if the arrow is lit backward, then the chuck turns counterclockwise and unscrews screwdriver.
Types of bits for electric screwdrivers according to their application
The shape of the bit’s working part determines what it is designed for. According to this feature differ heads :
- Spring bits and magnetic bits;
- with forked design;
- for drywall;
- With a vandal-proof slot;
- for nuts and bolts.
Experts advise to buy a set of nozzles. Sold individually, they cost more.
Many fasteners are driven with these bits. Approximately 400 screws can be screwed in and tightened with these bits, and then the bit remains in good condition. For the manufacture of professional bits use high quality metal. Items are protected by a special coating.
This kit usually includes a torsion bit for an impact model of an electric screwdriver. It differs in appearance. The torsion product has a very narrow area between the slot and the shank. It has a special flexible insert in the form of a spring. working for torsion. Thanks to this design, torsion bits are used when screwing into materials with a non-uniform structure or very dense materials. Self-drilling screws are used. With a similar head you can sink a screwdriver into the metal as a whole, including the cap.
Bits designed for drywall sheets have a stopper. It prevents the material from being damaged during assembly. Drywall is a fragile material, so screw in screws without strong pressure.
Bits that can be used to tighten and unscrew nuts and bolts have irregular shapes. The working part of these heads has a hole. Such bits are made in different sizes. If you have to screw in bolts and nuts with large flats, you need an electric screwdriver with high power.
Nozzles that are equipped with an anti-vandal slot also have another name. snake eye. The shape of this tip is adapted to a fork wrench.
Bit with fork-type construction is a type of anti-vandal slot. It looks like a flat head, but it has a slit in the middle. These products are made of quality steel. so they stand out for their strength and durability.
Bits with magnetic tip and spring clip are designed for work in hard-to-reach places and on the ceiling. The bit retainers hold the bit in the adapter. The magnetic tip holds it securely in the screw notches, prevents the bit from slipping, the screwdriver can be driven deep. The spring bit makes it possible to work with fasteners at different angles and hard-to-reach places.
How to insert the bit correctly into an electric screwdriver?
Before you start using an electric screwdriver Bosch (Bosch), DEKO, Makita (Makita), Vihr, Zubr, Devolta, AEG pick up the nozzle. It must fit the size of the flat of the fastener. To fit the bit in an electric screwdriver with a quick-action chuck, put it between the open jaws and turn the sleeve clockwise.
To fasten the bit in the tool with the key chuck. It is inserted into the socket and turned clockwise until it is completely fixed. To make sure that everything has been done correctly, first switch on the electric screwdriver in idle mode. Check the accuracy of the direction of rotation, it must coincide with the screw.
Using Power or Electric Drill as Electric Screwdriver
To remove the bit, switch the tool into reverse
How to remove the bit correctly
To increase the speed of the work you also need to know how to get the nozzle out of an electric screwdriver. To quickly unscrew the bit, switch to “reverse” mode. Then lock the chuck and start the machine. This will loosen the clamping of the jaws and the element can be easily removed.
It is not uncommon for craftsmen to ask how to remove the bit from an electric screwdriver, if it is jammed. It can get stuck in any type of chuck for the following reasons:
- accumulation of a large amount of debris, dross under the shaped frequent cams;
- Fixation in the holder of the tool, the size of which is larger than allowed;
- Poor quality material or overheating of the bit.
If such situations occur, it will not be possible to work with the tool. There are several ways to help remove the jammed element yourself, but if you do not have the necessary knowledge, it is better to solve the problem in the service center.
We recommend removing the drill bit or bit only after you have thoroughly lubricated the chuck with WD-40. In this case, the element must be removed, and then pour the grease until it flows over all the cams. After 15 minutes. the tool holder is clamped in a vice, the jaws are tapped with a hammer (preferably a rubber one), placing a cloth or a wooden bar. When the cam grip loosens, the nozzle will easily unscrew.
If it is not possible to achieve a positive result, the cartridge is heated with a hair dryer.
Sometimes masters use adjustable wrenches for tool extraction. One clamping the cartridge and the other gently unscrewing the top of it. Avoid damage to parts by using soft, thin, but tight spacers.
How to use an electric screwdriver
We’ve seen more than a few novice DIY enthusiasts attend our DIY Divas and DIY Guys seminars. One common problem that seems to occur over and over again is using a screwdriver in a cordless screwdriver or drill/driver.
It is important that you use the correct screwdriver bit for the type of screw you are using.
During workshops, especially for furniture projects, we often hear drills/drivers spinning at high speed along with an accompanying “taka-taka” indicating that the screwdriver head is coming off as it moves into the project.
The bad news is that the screw has already been removed, which means you’re going to have to fight to get it off again. The good news is that if you do it right, you will no longer have a problem.
If you have attended a DIY Divas power tool for beginners or a woodworking shop, you know that it is important that the screwdriver bit be firmly secured in the screw head. If not, you will very quickly remove that screw and damage the screwdriver bit.
Using the right bit
It is important that you use the right screwdriver bit for the type of screw you are using.
The most commonly used screwdriver bit for medium wood screws is the PZ2. Look at the bit and you will find it engraved on the metal.
Always make sure the screwdriver bit is held securely in the head of the screw.
If you are not sure, hold the bit at a 45 degree angle.If the screw stays on the bit and doesn’t fall off, you are using the right bit.
Screwdriver bit securely in place
Always make sure the screwdriver bit is securely held in the head of the screw.
Apply pressure to the top of the screwdriver or drill/driver while drilling to keep the bit in the head of the screw while drilling.
To prevent a screw or screw from slipping when cutting into wood, gently grasp the sides of the screw to hold it in place until it begins to dig into the wood.
You can do this for pine, but if you’re going for hardwood or superwood, pre-drill a test hole.
To prevent a screw or screw from slipping when cutting into wood, gently grasp the sides of the screw to hold it in place until it begins to bite into the wood.
Use a magnetic screwdriver bit holder. This also holds the screw in place on the end of the bit. Where you are installing the screw, press down hard to make a recess, and this will make it easier to hold the screw straight.
If you find that the screwdriver tip is still slipping out of the screw head, then you are not applying enough pressure to hold it in the head. To compensate, press your left hand harder on the back of the planter or put your shoulder in it.
Don’t forget to release pressure when the screw is almost in place. Too much pressure and you will end up driving the screw too deep into the wood or board. Quick on and off will also give you more control over how deep the screw plunges into the wood or board.
As the saying goes, practice makes perfect, and the more you screw in, the more you know what works best for you Janice Anderssen

Electric screwdriver chuck repair with your own hands
It’s a moving part of the tool that consists of many rubbing parts. In the process of operation, it is subject to wear and tear, resulting from the action of friction forces, impact forces and other factors. Chuck runout, its excessive backlash can scare an inexperienced master. In some cases it is not always possible to find the time or money to go to a repair shop. Therefore we will consider how you can do with your own hands when repairing various malfunctions of the tool.
Electric screwdriver repair with your own hands in case of chuck play
A small backlash within 1 mm usually does not cause visible problems during operation. If it is larger, pay attention to the condition of the gearbox. So, the order of actions is as follows:
- Loosen the screws that secure the upper cover of the tool. Remove it.
- Unscrew the electric motor from the gearbox. Inspect fasteners.
- Disassembling the Geareducer. The damage is often caused by a defective bushing inside the screwdriver. It is possible to take out the bushing with the help of actions, described in the beginning of the article (we look how to remove the chuck manually). The bushing is easily pressed out by hand.
- Replace the hub. Then assemble everything in the following order: sleeve, shaft, sleeve bearings, retaining ring. Lubricate the rubbing parts.
- Then assemble the gearbox in reverse order. Attaching it to the electric motor.
- Reassemble the body of the electric screwdriver.
Repair of electric screwdriver with your own hands in case of chuck run-out
The main culprit of this problem is the gearbox of an electric screwdriver. To be sure, you need to remove it by disassembling it as above. This particular fault could indicate a few problems in the gearbox as follows. The cause may be:
- geometry of the gearbox shaft is broken;
- gear wheels are worn out;
- failure of the shaft support bearing;
- wear of the pins that fix the planetary gear satellites.
The above parts are only produced in factories, so you can’t make them yourself. You only have to buy them and replace the failed.
How to remove a drill bit from an electric screwdriver
However, the electric screwdriver itself works, the chuck rotates, but because of this failure you can not use it.
Try knocking lightly, treat with ud-40, more knocking. Most importantly. do not overdo it. I was in a similar case, sprinkled kerosene inside and let stand a couple of days, then knocked a couple of times lightly and the cartridge went. If it doesn’t work, you have to take the cartridge off and disassemble it.
Why a bit can jam in an electric screwdriver
Whether it’s an expensive or cheap tool, jamming a chuck is not uncommon. There are several cases where this occurs:
- When trying to use a drill bit of the largest allowed size, the chuck jaws open to the maximum value, after which it is often impossible to squeeze them in normal mode.
- You can’t get a jammed drill bit or bit because you can’t get it out because the cams aren’t unclamped. in most cases because they are unevenly pressed.
- The jaws can get jammed because of the free play during clamping and unclamping. The reason for this is debris, shavings, dross that gets caught inside the shaped parts of the cams.
Unfortunately, in such situations it is not possible to work with an electric screwdriver, even if it is in good working order. It is possible to cope with the problem yourself, in severe cases it is better to turn to a service center to the professionals.
Is it necessary to repair an electric screwdriver if there is a stuck bit
Regardless of what model of electric screwdriver (Makita, Bosch or Metabo), at the initial stage you can try to remove the bit yourself. Remove the element with care so as not to damage other parts.
Before removing the bit from an electric screwdriver, it is advisable to inspect the tool carefully. You should clean it and then try to remove the stuck bit. As a rule, with such a problem, the electric screwdriver remains in working order, so it does not need a complete repair.
To give the tool to a workshop will be necessary if you can not remove the element yourself, and at further attempts damage may occur.
It is relatively easy to remove and refit drill bits in the quick-action chucks. In such devices the sleeve is operated by manual rotation. To avoid excessive tightening of the cams, they are often equipped with locking elements.
Specialists recommend making sure that the tool works before inserting the selected bit in its place. It is imperative that the product is unplugged.
Warning! The bit jamming in the chuck of an electric screwdriver is most often the owner’s fault. To prevent this from happening, it is recommended to service the tool in time, keep an eye on its condition.
It is necessarily important to check that there is no debris stuck in the chuck, clean it in time. When working, it is necessary to ensure that the product does not overheat, give it time to cool down. If necessary, additional diagnostics must be carried out to detect possible problems in good time.
Do not disassemble the tool yourself in difficult situations, otherwise you could ruin it completely. It is better to contact a professional to get the job done.
