Any master, whether professional or amateur, has in his arsenal a whole range of different tools. They are simply necessary to perform a number of functions required in the process of construction or repair work. So that the equipment does not take up too much space, many users purchase universal devices that can perform several tasks. One of these tools is an electric drill / driver. There are many types of such equipment. How to choose the best instance, answer the reviews of experts in construction and repair business, as well as ordinary users.
General characteristics
An electric drill or screwdriver is a tool whose main purpose is to drill holes of various diameters in materials. For example, it can be metal, plastic, wood, ceramics, brick and even concrete. These are its main functions.
But, in view of the presence of a screwdriver function, the equipment is used to tighten or unscrew bolts, threaded fasteners, and self-tapping screws. Also, builders quite often use a tool such as an electric drill screwdriver to mix mortars, clean all kinds of surfaces or grind. And this is not a complete list of its features.
The presence of special cartridge nozzles allows the use, according to experts, of an electric drill as a universal tool with a wide range of capabilities.
Purpose of the tool
To understand how to choose the right electric drill screwdriver, you need to decide in what conditions, with what loads it will work. The modern market of construction and repair equipment offers a wide selection of tools. At the same time, household and professional tools are separated.
For home use, a less powerful, but cheap electric drill / screwdriver is more likely. How to choose professional equipment for the work of builders, prompted by higher power. Such an instrument is subjected to frequent and rather large loads. Therefore, increased demands are put forward on it, in comparison with a home device.
Professional electric screwdrivers have a higher price. It is approximately 2-3 times higher than that of products intended for household repairs.
Manufacturers and cost
If we consider the presented devices from the point of view of the best manufacturers, then there are leaders in both the production of professional and household type of equipment.
Among high-quality reliable options intended for use at home, it is worth highlighting such models as the electric drill “Enkor” DE-450ER / 10, FIT-80014, Gardenlux CD14-22, as well as the products of Interskol, Zubr and other domestic manufacturers.
Professionals usually choose models such as Bosch GSR 36, Bosch GSR 18, as well as Interskol DU800ER, Makita-4700, Enkor DE-500ER / 10, etc. Such models withstand heavy loads, shocks and falls from a height of 2 meters.
A professional electric drill / driver, the price of which will be about 15-20 thousand rubles, will not be affordable for every home master. Therefore, for household purposes, models worth about 2-5 thousand rubles are quite suitable.
Drill or screwdriver
In addition to the cost and purpose from the point of view of professional or household use of the device, you should pay attention to its technical characteristics.
Each model of the tool better performs the functions of either a drill or a screwdriver. Therefore, before making a purchase, you should decide whether a new tool is needed to tighten the fasteners or to drill holes.
If during the selection process the user focuses on the preferred function of the drill, then the technical characteristics of the device should indicate that the number of revolutions per minute is at least 1000.
For mounting and assembly work, equipment with such an indicator as 500 rpm is suitable.
Processing material
The maximum torque makes it clear what maximum load the tool can withstand.
Usually for modern tools, such as an electric drill / driver FIT, "Interskol", "Zubr", "Makita", "Metabo", it is 5-30 N * m. For professional purposes, when performing work of increased complexity and accuracy, equipment with a torque of 100-150 N * m is used.
Typically, models with medium or high torque have a mode switch. This makes the tool universal and allows you to work effectively with any material.
Products with medium torque, such as Bosch GSB 14,4-2, Gardenlux CD18-2M and others, can be considered optimal models.
Shock function
So that a conventional drill / driver can work with durable materials, manufacturers provide for a shock function in it. This will allow the processing of steel or concrete. There are a large number of models of equipment considered with a shock function at fairly reasonable prices.
For example, they can include such as an electric screwdriver "Interskol DU 780 ER", Bosch PSB 14,4 LI-2, Sparky BUR2 250CE, etc.
Although many models do without this feature. This is especially true of the tool used for installation and assembly work. The cost of this technology option will be cheaper. For example, if you plan to work only with wood or plastic, the Gardenlux CD 12-2M model is suitable.
Cartridge
Screwdrivers have different types of cartridges. If it is a hexagon, then the shank change speed will be fast. For mounting work, this type of cartridge is just perfect. It is possessed, for example, by the Bosch PSR 7.2 LI model.
Another type of cartridge is a keyless chuck. It allows you to mount all types of consumables. The convenience of such a device is also undeniable, because a little hand effort and the presence of the "Reverse" mode are enough to set a bit or a drill. True, the replacement process takes a little longer. This type of cartridge has a model Bosch GSB 14,4V-LI L-Boxx. Also, equipment can be accelerated by spindle lock. Such a cartridge has an electric drill Bosch GSB 14,4V-LI.
Additional equipment
Today, manufacturers of the equipment presented offer many additional product features. The most popular of them are a lamp, a backlight on the case, as well as elements that expand the capabilities of the device. Each additional element increases the cost of production. Therefore, the degree of need for such functions should be assessed.
For example, with a professional impact type of equipment, the manufacturer may offer an additional cartridge, depth gauge or handle.
An inexpensive electric drill screwdriver designed for domestic use may have a backlight on the case. It happens that a company completes its products with an additional set of drills.
Fake
Among the expensive and cheap varieties of the equipment presented there are fakes. Their quality is significantly different from the original. Moreover, their cost may be even higher than that of the present technology.
To avoid acquiring a fake, you need to buy products only from reliable suppliers who faithfully control the quality of products. There are also characteristic signs of fake. One of them is the lack of warranty. For example, an electric drill-driver “Makita”, “Interskol”, “Ankor” and many others, have a 12-month warranty. It is provided by the manufacturer. The ticket must be fully filled.
You should also pay attention to the presence of the original packaging, all delivery components that are listed by the manufacturer. This will avoid the purchase of low-quality fakes.
