Cordless drill: the quick way to secure all connections

Important selection criteria

Each user independently evaluates what is important to him in a particular instrument or its model. You should not make a decision by looking only at the photo of screwdrivers.

The technical characteristics, usability, design, and also the price are important. But when choosing, you must take into account the purpose, as well as your level of professionalism.

The most versatile options are:

Engine power, which affects the speed of work, and the effort applied by the foreman.
Class. There are household and professional screwdrivers that differ in functionality. You can also find combined options that do not relate unambiguously to the specified classes.
Battery characteristics. For products that are able to work autonomously, this factor is often decisive. All types of batteries have their own advantages and disadvantages, so they need to be correlated with the mode of future operation and the purpose of use.
Reliability of network mode

If you choose this option, then you need to pay attention to reliability and safety.
Comfort in use.
Technical parameters, additional options and customization options. Each craftsman selects the most valuable of them - ranges in terms of speed, adjustment of the clamping system, illumination, etc.
Price

The more top-end model and the more functionality it has, the more expensive it will be. But not all options are important and in demand. Therefore, it is always necessary to select an option taking into account the entire set of criteria.

Types of bits for a screwdriver: how to choose

To choose the right nozzles, you need to study their varieties. First determine the shank shape type and diameter. It comes in from 1/4 to 1 inch.

Shank classification:

• basic;
• special;
• combined.

Basic bit types:

• slotted. They differ in the width and thickness of the slot;

• cross. They have a different angle at the base and shape;

• hex. The main characteristic of the bit is the distance between the sides of the hexagon;

• tetrahedral;

• asterisks. This shape improves the adhesion between the nozzle and the fastener.

Kinds of special bits:

• tri wing or triangular;

• double pin. Similar to slotted, but with a notch in the middle;

• torq set. As triangular, but with four rays;

• end. Usually performed with a magnet;

• for drywall. They have a persistent stop;

• with a spring clip.

Combined bits have two types of shank shapes or one, but different sizes. For example, splined shank and sprocket.

Combination nozzle example

Splined shank and sprocket

Determine the bit length you need to work. It ranges from 10 to 200 mm.

Depending on the shape of the shank, the bits have a certain marking:

• Sl (Slot) - slotted;
• Ph (Philips) - universal cruciform;
• Pz (Pozidrive) - cruciform with additional thin ribs;
• T (Torx hole) - asterisks;
• H (Hex) - hex.

An important characteristic is the steel grade from which the bat is made. The attachment may have a protective coating

The strength of the equipment depends on this. The main types of steel and coatings that should be preferred:

• Cr-v - chrome vanadium steel. The most common, with increased hardness;
• Cr-Mb - chromium-molybdenum steel. Less common. Very durable material;
• Ni - nickel plating. Increases corrosion resistance;
• WC - tungsten carbide coating. Increases strength;

• Tin - Titanium nitrite yellow coating. Increases strength.

The attachments differ depending on the purpose:

• twisting and unscrewing;
• drilling;
• riveting;
• polishing;
• milling.

Considering all the parameters discussed, you can easily select the necessary bits.

Model overview

Stanley has a good selection of battery equipment. The user, in order to make a choice, needs to learn more about each of them.

Stanley STCD1081B2 is the most commonly purchased model due to its small size and weight. It can boast of an acceptable cost, but the functionality is significantly limited. This tool is designed for solving everyday tasks. It is reliable, easy to operate, and its body is well balanced.

To illuminate the working area, you can turn on the backlight, which is directed exactly where you need it.

The tooling is changed on the keyless chuck, the shank diameter reaches 10 mm. There are two gearbox speeds, and the torque is at around 27 N * m. Supplied with case, second battery and charger.

Stanley SCD20C2K is the perfect combination of the cost of a household screwdriver and professional performance.

The backlight is bright, so the work surface is perfectly illuminated. The shank diameter at its maximum value reaches 13 mm, the chuck has a quick-release type.

Stanley SCH201D2K is a screwdriver with an additional impact function, which significantly expands the scope. The manufacturer has provided an additional holder for equipment on the body, which is simply irreplaceable when you have to work at height. When changing the nozzle, an automatic lock is triggered.

Magnetization and hardening of nozzles

A large number of nozzles are made in China from a soft material. Therefore, they quickly lose their shape. The new beat doesn't last long. To prolong the life, the bit must be hardened. You will need: machine oil, a gas burner or gas stove, a small container for oil from any tin can, a piece of steel wire.

1. Wind the wire around the bit so that it does not fall out.

2. Pour oil into a container. Ignite the gas in the burner and heat the bit red hot. The main thing is not to overheat.

3. Dip the red nozzle in oil for 5-6 seconds. Remove for 2-3 seconds. Do this several times.

A hardened bit will last longer than a normal bit.

For the convenience of work, especially in hard-to-reach places, the attachments are magnetized. This can be done in several ways.

Method 1

You will need to purchase a special device for magnetizing and demagnetizing screwdrivers. Insert the bat there.A square window magnetizes, and a stepped window - vice versa.

Method 2

1. Take the insulated wire and wind the spool in three rows around the plastic tubing.

2. Insert the bit inside.
3. Connect the ends of the wire to the battery terminals. If not, then take a battery. To enhance the effect, connect three or two batteries in series.
4. Hold the bat inside the coil for a minute. Check the result.

Method 3

1. Take a magnet and rub the attachment on it from all sides.

2. It is now magnetized. Try to hold the fasteners. Repeat as necessary.

Method 4

1. Buy neodymium magnets from a radio store.

2. Divide them into two parts and put them in one row so that the formed groups repel each other. Place the plastic pen cap between them. Secure the repulsive magnets with plasticine to hold them in place.

3. Insert the bit with the working end between the magnets. Leave the structure for 10 hours.

As a result, the nozzle will magnetize the fastener better than a new one.

Where is applied

Screwdrivers are widely used in installation operations, organized both at home and in production. On this basis, devices can be classified as universal devices.

The possibilities of screwdrivers are also used by professional builders who have to deal with large volumes of prefabricated structures. When using them, the speed of performing monotonous operations for arranging standard fixtures increases significantly.

At the same time, the quality of the formed mounting connections increases, since, in addition to their main function, screwdrivers can have such an additional option as drilling, which must be taken into account when choosing.

Which screwdriver manufacturers are considered the best

Before you understand how to choose a cordless screwdriver, you need to determine which companies are the best and produce the most demanded products on the market. There are a lot of manufacturers of screwdrivers, the market is literally overflowing with products of various brands. We will briefly tell you about the most famous manufacturers that produce high-quality and reliable devices.

Bosch

This is a company from Germany that produces tools for both the home (featuring a green body) and for professional use.A household appliance of this brand is quite enough to assemble furniture or tighten small fasteners. But more productive and efficient devices for professionals are able to work for a long time in difficult conditions. Good for all day workshop work.

Makita

One of the most famous and long-standing (operating since 1915) firms producing tools for construction work. The Japanese manufacturer carefully controls the quality of its products, constantly introducing technological innovations. The most popular among consumers are drills and screwdrivers of this brand, equipped with a battery. They are versatile and suitable for both home and construction work. The company is constantly improving the tool.

Metabo

The German manufacturer (previously called Schnizler GmbH, then Metabowerke GmbH) with more than eighty years of experience has received well-deserved recognition during this time. And the name "Metabo" was given by the manufactured hand drill, which received a record number of sales. The power tool of this brand is reliable and of excellent quality. The wide range includes both household and professional models. With them, you can easily perform even the most complex construction and repair work.

AEG

The German company, founded in the last century (1887), produces very reliable and versatile devices. Drill drivers of this brand are well suited both for making holes of various diameters, and for connecting parts with nuts, bolts, screws. Distinctive features of the brand: high-speed chuck, quickly clamping and unclamping, as well as an excellent engine cooling system.

DeWALT

There are few models of this brand, but each of them is carefully thought out by the developers. All screwdrivers have good speed characteristics, high working efficiency, small dimensions. They are collected very high quality, marriage never comes across. So buyers love this brand and purchase it with pleasure.

Ryobi

This American firm began with aluminum die casting. Well, and later she began to produce motors and spare parts for them. Later still, there is a garden tool and all kinds of electric tools. The screwdrivers produced by the company have a wide power range, which allows the consumer to always find what he needs. The devices are of high quality and very reliable.

Hitachi

Another serious and reliable company that is attentive to the quality of its products. Her tool is ergonomic, technologically advanced, modern, it is actively used both in domestic conditions and in production. The devices are light and quiet. It's a pleasure to work with them.

Summarizing

You should not strive to acquire the most powerful tool. With excess power, you will screw in the screws too hard, the head will be deeper than the surface, which spoils the appearance and makes it difficult to unscrew the screws if necessary.

Before choosing which power of the screwdriver is right for you, you should decide for what purpose the tool will be used. For rare use in a home workshop, a simple low-power tool is suitable, with a voltage of 12V, a capacity of 1.5Ah and a maximum torque of 25Nm. Such a tool can be used when assembling furniture and screwing in small self-tapping screws for attaching home furnishings (curtains, paintings, etc.).

Always try to choose a screwdriver with 2 batteries included as batteries are an expensive replacement part.

It is worth noting that the power of the screwdriver's battery, although it is an important parameter when choosing a suitable model, is much more important than the voltage, capacity and type of battery.

And it is often worth paying attention to the torque only if it will be used not only for screwing in, but also for drilling.You should also know that the maximum power of a cordless screwdriver of all commercially available models has a device with a voltage of 36 V, a torque of 60 Nm and a capacity of 3000 mAh

Such equipment is rather difficult and not very convenient to use on a daily basis without professional experience. And, therefore, you should opt for less productive options produced by well-known and reliable brands such as Bosch, Hitachi, Makita, AEG, Dewalt and Metabo. Even if you buy a screwdriver with insignificant characteristics, these models of screwdrivers will last for many years.
