A screwdriver is a tool that is mainly used for screwing and unscrewing screws and bolts. It saves the craftsman effort and time. Imagine, for example, that you have to assemble a large wardrobe or section. With a screwdriver in your hands, this will happen in minutes.
The screwdriver is used by both professionals and amateurs in assembly and repair work. The impact-drilling models of this tool also have a function for drilling holes.
TYPES OF SCREWDRIVERS
Screwdrivers can be of two types: cordless and electric. The former are more common. This is because they can be used anywhere and are not dependent on access to a mains power supply.
Cordless screwdrivers are equipped with a standard quick-clamping chuck, which allows you to hold tools with both hexagonal and cylindrical shanks, such as drills or with a hexagonal bit adapter. These tools can drill various materials such as steel, non-ferrous metals, wood and plastics.
Cordless hammer drills are equipped in the same way. These machines can also be switched to an impact mode for use in light drilling work in brickwork.
HOW TO RECOGNIZE A GOOD SCREWDRIVER?
Every handyman wants to own a screwdriver that is powerful and can work for a long time on a single battery charge. We will help you with valuable tips on how to recognize a "purebred" machine.
First of all, we can focus on the capacity and voltage of the battery. The higher the capacity, the longer the device will work on a single charge. The higher the operating voltage, the more powerful the tool.
Different screwdriver models have different voltage and capacity values. The voltage varies from 3.6 V to 36 V. The battery capacity of cordless screwdrivers ranges from 1 Ah to 5 Ah.
When choosing a cordless screwdriver, you should also consider the frequency and duration of use you expect. Accordingly, we choose whether to get a machine with one battery or two. For longer work, one battery is constantly in the charger and waiting to "come into play", which is a guarantee that we will not have to interrupt work.
Also, when choosing a suitable cordless screwdriver, the charger should not be underestimated, especially the time it takes to charge the battery to 100%. Usually, this time is several hours. There are now also fast chargers on the market that can charge the battery to its full capacity even in 30 minutes. A novelty in cordless technology today are wireless battery charging systems.
Speeds are also an important parameter. It is an advantage for a screwdriver to have more speeds. With such a model, you can handle various tasks.
Torque adjustment is also one of the main features when working with a screwdriver. It determines at what resistance the material will stop the screw from being screwed in. Thanks to this function, we can control the depth of screwing and protect the base material from damage by deep penetration of the screw head into it.
In hammer drill models, smooth speed regulation with the trigger button is important. This is an advantage when performing precise drilling, especially during the initial centering and penetration of the drill bit.
The maximum torque value determines the maximum force that can be achieved when turning. We distinguish between two types of screw connections: "hard" (screwing into ferrous and non-ferrous metals) and "soft" (which refers to screwing into wood and softer metals).
Recommended screwing and drilling values are specified by most manufacturers in their data sheets and instructions for use – maximum recommended drilling diameters in materials such as wood, steel, aluminum, brick and the maximum screw diameter, respectively. These values should not be exceeded, as this may lead to serious product defects.
WHAT DO WE OFFER?
We offer a variety of screwdrivers of both types, with the more preferred cordless models prevailing over the electric ones. Among battery-powered devices, the leading share falls on a reputable brand such as BOSCH, which we trust not only in this product group. The German company is a symbol of proven quality, and in this particular case it is one of the world leaders, producing a wide range of cordless screwdrivers.
BOSCH cordless screwdrivers are compact, lightweight and powerful universal tools for cordless drilling and screwdriving. They feature innovative battery technology and a high degree of ergonomics, which allow them to work optimally in any position.
BOSCH cordless drills and screwdrivers are the most popular among DIY enthusiasts, with a significant lead over the most commonly used power tools in normal household conditions. The PSR series screwdrivers, for example, score points above all for their ease of use, ease of maintenance and independence from the mains. The compact power packs also have a decisive advantage: they can drill and screw in first-class quality anywhere and at any time, making them true all-rounders.
Most of the BOSCH models are equipped with lithium-ion batteries, which are considered the most reliable. These batteries are lightweight and have a high energy density. They do not exhibit a “memory effect” (loss of capacity in violation of the charging mode) and the level of self-discharge is less than that of other types of batteries. In addition, lithium-ion batteries for screwdrivers are not considered an environmentally hazardous product.
In the product group you will find a wide range of different brands of screwdrivers such as MAKITA, PREMIUM, RAIDER, SKIL, DEWALT, SPARKY, BAUKRAFT, RAPTOR and many others. There is also a great variety in the technical parameters of the models. Almost all of them have different speed indicators, as well as battery capacity and voltage. The models boast many extras, which you can see in their personal technical cards.
