How to put a bit in an electric screwdriver?
To install the required bit, you need to match it to the size of the cap of the fastening element and insert it into the magnetic holder of the chuck. To do this the chuck and socket 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 frequency of rotation of the bit.
To remove the drill bit or bit, you turn the electric screwdriver in reverse, lock the chuck and turn the electric screwdriver on: the jaws open and release the drill bit or bit. What has become a standard in electric screwdrivers is the torque-limiting clutch. At the top of the housing, opposite the chuck, there is an arrow that indicates the number.
How to release a jammed chuck of an electric screwdriver
In the case of the described problem, there is a logical question of how to pull the drill out of an electric screwdriver, when the element is jammed.
At the first stage, professionals recommend pouring into the inside of the chuck (touching the surface of the cams) a universal grease of WD-40 type. Kerosene or machine oil can also be used instead. Similar solutions are recommended in any case of jamming.
Jamming often occurs through improper use
After 10-15 minutes, the chuck and jaws need to accurately knock through the gasket with an ordinary or rubber mallet. As a rule, the grip is loosened and the drill bit is released.
If this does not happen, it is allowed to warm up the chuck slightly with a hair dryer and try to remove the bit again. The method is suitable for owners of screwdrivers with standard and quick-clamp fasteners.
How To Use a Screwdriver Bits With Drill (Correctly)
Remove the jammed bit can also be done with two adjustable wrenches. After the grease is added inside, make quite simple actions:
Use the first wrench to squeeze the base of the chuck and the second wrench to gently twist the upper part of the chuck.
It is recommended to place soft pads between the parts, so as not to damage them while they are unscrewed.

There is another method by which you can cope with such a problem. It is necessary to immerse the bit into a container with machine oil (even vegetable oil will do) or petrol for one hour. After this period of time, remove the bit and use the above described methods to remove it from the bit holder.
If you can not carry out the procedure yourself, it is better to turn to professionals, so as not to spoil the tool.
There are several methods for extracting the bit from the chuck
Care of the tool
You can extend the life of the screwdriver by cleaning it with a soft rag in a timely manner. Do not expose the screwdriver to water and water. Keep in a dry place. Do not throw the screwdriver. In an effort to carefully handle the screwdriver, look after the battery charger and its power cord as well. If you notice either problems with the screwdriver itself or problems with the battery charger, you should try to contact a service center. Speaking to professionals, you will receive high quality repairs and quality parts that will significantly prolong the life of your screwdriver.
This tool is usually sold in a special case with a separate location for each part.
Electric screwdriver itself consists of a basic tool and a removable battery that is recharged by a household electronic network.
To charge the screwdriver, use a special charger that comes with the set.
The electric screwdriver comes with several kinds of bits with different shapes of bit tips.
Bit with straight edge is designed for fasteners that have a single slot. Depending on its length and depth, the right bit is selected.
Similarly the shape of the cross-head bit is selected. In this case the width of the slot and the dimensions of the fastener head itself are taken into account. In order to work reliably, the edge of the bit must fit tightly into the slots, otherwise there is a possibility of “slipping” of the slots faces.
To fix the bit in the chuck a special nozzle with a magnetized holder is used, which prevents the construction from falling apart and securely holds the bit in many different positions.
To secure the bit and bit holder, unscrew the sliding part of the chuck.
Insert the bit and twist the chuck until it stops.
There are also very practical double-sided bits that can be fitted in the chuck without the bit.
Magnetizing and hardening bits
Mostly Chinese-made nozzles are dominant on the market. They are made of soft material, which causes their rapid loss of their original shape. It cannot be restored, so these specimens are characterized by low durability.
To avoid constantly buying new bits it is recommended to perform their hardening. To perform the procedure wind a piece on the bit and heat it up to red over a gas torch. After the bit has turned red, it is lowered into a tin can previously filled with machine oil for 5-6 seconds. This operation should be repeated several times, with breaks for 2-3 seconds. The element is considered to be hardened after blackening.
The magnetizing procedure will make the work more comfortable. There are several ways to do this:
- The bit is placed with its working ends between two neodymium magnets, which are placed so that they repel each other. They are held together with plasticine. You should wait for the effect to happen for at least 10 hours.
- Insert the bit into a special device for magnetizing and demagnetizing screwdrivers. The desired effect is achieved by placing the element in a square window.
- Copper wire, from which the insulation is stripped off beforehand, is wound in 3 rows on a plastic tube. The nozzle is inserted inside. The ends of the wire are connected to a battery or battery terminals. To enhance the effect, connect 2-3 batteries in series. After a minute, evaluate the magnetization result.
Masters also offer a simple variant. The tool is rubbed on all sides against the magnet. Try to hold the fastener. If necessary, repeat the manipulation.
Types of bits for an electric screwdriver by function
The shape of the working part of the bit depends on what it is designed for. The heads are differentiated by this feature :
- Spring and magnetic;
- With the “fork” design;
- For drywall;
- With an anti-vandal slot;
- For nuts and bolts.
It is advised to buy the bits as a set. Sold individually, they cost more.
Many fasteners can be driven with such bits. Approximately 400 screws can be driven and tightened with these bits, and the bit remains in good working order after that. Professional bits are made of high quality metal. Products are protected by a special coating.
Usually includes a torsion bit for the 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. Torsionally working. Thanks to this design, the torx bit is used when it is necessary to screw into a material with a non-uniform structure or very dense material. Self-drilling fasteners are used. With such a head you can drive the whole screw in the metal, including the head.
Bits that are designed for drywall sheets have a stopper. It prevents from damaging the material during installation. Drywall is a fragile material, so screw in screws without strong pressure.
Bits, that can be used for screwing on and off nuts and bolts, have irregular shape. The working part of these screwdrivers has a drill hole in the middle. Such bits are made in different sizes. If you want to drive nuts and bolts with large flats, you’ll need a high-powered electric screwdriver.
Bits that are equipped with an anti-vandal slot also have another name. The snake-eye. The shape of this bit is adapted to a fork wrench.
Bit with fork-type construction refers to a type of anti-vandal slot. In appearance, it resembles a flat head, but it has a slot in the middle. These elements are made of quality steel. So they stand out for their strength and durability.
Bits with magnetic tip and a spring clip are designed for jobs in hard-to-reach places and on ceilings. Locks hold the bit in the adapter. The magnetic tip keeps the bit firmly in the grooves of the screw, prevents the bit from slipping and the screw can be driven in deep. The spring bit allows you to work with fasteners at different angles and in hard-to-reach places.
