Today, a screwdriver is a device that can cope with many construction and repair tasks. Thanks to him, you can drill holes of any diameter in various surfaces, quickly tighten screws, work with dowels.
The device is used for various types of surfaces: from wooden to metal. The device is small and compact.
" Caliber" is a new generation screwdriver . The country of origin of this device is Russia. This manufacturer introduced its product to the market not so long ago, but the products were able to gain popularity in a very short period of time. The manufacturer offers good tools that are fully consistent with the price-quality ratio.
If you are looking for a quality tool for home or professional use, then take a close look at the Caliber series of screwdrivers.
Peculiarities
Screwdrivers "Caliber" are divided into three main types:
- Power drill.
- Electric screwdriver.
- Cordless screwdriver.
The first option allows you to work with self-tapping screws of any size as well as drilling holes in iron and wood surfaces. As a rule, this device weighs about a kilogram and is endowed with small dimensions.
The screwdriver boasts a reverse, a keyless chuck, a "soft" rocker for changing the speed and the presence of a drilling mode regulator.
The second option was created specifically for working on metal surfaces . It consists of mechanical gearboxes made of metal, as well as a limiter, thanks to which the rotation will automatically stop at the right time.
The third type of tool is the most popular among ordinary buyers . The tool allows you to perform two tasks at once, as it acts both as a drill and as a screwdriver. Suitable not only for locksmith and carpentry work, but also allows you to work with impact-resistant plastic.
Advantages
Screwdrivers "Caliber" can be used away from power sources due to the presence of capacitive batteries. They can actively work for six hours without being connected to electricity. The tool will serve its owner for many years, as the manufacturer pays special attention to the build quality. This product can be used for both domestic and industrial purposes.
For professional use, the manufacturer provides a special series of screwdrivers called "Master ". There are some additions to the line, besides the basic configuration, namely: a compact dock, a charger, a couple of additional batteries, a portable flashlight, and a case made of shock-resistant material for carrying equipment.
However, standard screwdrivers are quite budgetary and cannot boast of good packaging - most often it is inexpensive cardboard. The package contains only a battery and a fabric case for carrying it.
Instrument characteristics
The manufacturer "Caliber" marks each product with the appropriate mark, which is an indicator of the device's capabilities. By numerical values, the buyer can find out about the electrical potential of the battery, and the letters show the capabilities of the functionality:
- YES - cordless drill.
- DE - electric screwdriver drill.
- CMM is a product for professional use. The device is fully equipped.
- ESh - electric screwdriver.
- A - a battery with a higher capacity.
- F - in addition to the basic kit, there is a flashlight.
- ะค + - additional devices, a case for storing and transporting the device.
The electrical potential of a device is directly proportional to its performance. The range of screwdrivers is a device with a voltage of 12, 14 and 18 V.
Devices with such indicators can easily cope even with hard surfaces.
The duration of continuous operation of the screwdriver completely depends on the capacity of the battery and external factors. The unit of measurement is ampere-hour.
The weight and dimensions of the product are proportional to its power . Some devices are equipped with additional functions, such as braking the motor or protecting the switch from unintentional pressing. Thanks to the reverse, the direction of the chuck can be drastically changed.
Battery
Rechargeable batteries for screwdrivers "Caliber" are divided into two types: lithium-ion and nickel-cadmium.
NiCd batteries are installed in devices of the budget series and are calculated for 1300 full charges-discharges. For such autonomous power supplies, too high or too low temperatures are not recommended. After 1000 full recharges, the battery begins to oxidize, which is why it gradually becomes unusable.
These batteries cannot be charged quickly. In order for the device to serve for a long time, experienced craftsmen do not advise keeping the screwdriver charged.
On the market, the most common options for electrical appliances operating on such batteries are DA-12/1, DA-514, 4/2 and others.
YES-12/1 . This version of the device is one of the newest models on the screwdriver market. It allows you to drill holes with a radius of about 6 mm in metal surfaces and 9 mm in wood. Such a product is not endowed with any additional features. But it is best suited for home use. The manufacturer paid great attention to the assembly of this product: the screwdriver does not play, does not make creaking sounds.
YES-514.4 / 2 . A tool of the middle price segment, which is positioned on a par with leading manufacturers in the world, for example, Makita, Dewalt, Bosch, AEG, Hitachi, Stanley, Dexter, Metabo. A keyless chuck is installed here, allowing you to change the equipment almost instantly.
The buyer can choose from 15 options for the rotation force of the engine crankshaft. The device operates in two speed modes. For comfortable work with the device, the handle has a rubberized insert, which additionally protects the person.
Li-Ion - batteries are quite expensive. But these products have several advantages over their competitors. These are environmentally friendly batteries that can be fully charged up to 3000 times. Products are not afraid of temperature extremes.
The lithium-ion battery life differs significantly from the nearest competitor for the better.
YES-18/2 . The screwdriver allows you to make holes with a radius of 14 mm. The well-known company Samsung is engaged in the production of batteries for this device. The device has a reverse function, thanks to which you can quickly change the direction of rotation. The manufacturer provides 16 options for the rotation force of the engine crankshaft.
YES-14.4 / 2 + . The product has 16 torque options. This means that you can easily choose the mode for working with a certain surface. The screwdriver is equipped with a two-speed operating mode. There is a cooler and a ventilation grill next to the engine.
Cartridge
Chucks for "Caliber" screwdrivers are divided into two main subspecies, which differ in clamping mechanisms: keyless drill chucks and hexagonal.
In the quick-release mechanism, the sleeve begins to move due to manual rotation . Thanks to this design of the device, such cartridges are considered the most reliable. With their help, you can fix the screwdriver well. The locking mechanism will allow you to control the pressure on the handle of the device.
Hexagonal chucks are used for industrial purposes. With their help, you can instantly change your rig. The cartridge has additional attachments that are flat on one side and polygonal on the other. The correct installation of the equipment is indicated by a soft click.
The size of the cartridge is also of great importance. The smaller it is, the simpler the device as a whole will be.
Impact screwdriver
According to the drilling mode, all devices are divided into two types: shockless and percussion. The hammerless screwdriver is perfect for homework when you just need to tighten a self-tapping screw or make a hole in a tree. The scheme of work is rather primitive. This type of chuck has no features other than rotation.
If you are faced with the task of drilling a hole in hard surfaces such as concrete or fired brick, then only an impact screwdriver will help you.
Its cartridge not only rotates in two directions, but also has the ability to move in a vertical direction, so you can save your own strength.
Owner reviews
Experienced specialists note a number of positive qualities. According to them, such a device copes well with both complex tasks and twisting the smallest parts.
Several options for the rotational force of the crankshaft make themselves felt . Thanks to these positions, you can not only drill holes of different diameters, but also perform any fastening and installation work. However, not all representatives of the Caliber series have a speed switch.
Due to its small dimensions, the load on the hand is practically not felt. All elements of the screwdriver are made of strong materials, and with careful handling, the tool will last a very long time. The manufacturer is distinguished by a budget pricing policy, which makes branded products available to everyone.
