Each home master very often needs to drill holes in metal, concrete, wood and other materials. In order to do this, a drill must be in the toolbox. And taking into account the fact that the most common fasteners of a modern master are self-tapping screws and screws of various types and sizes, a screwdriver will also not be superfluous.
It is easy to get by with a screwdriver for one or a pair of self-tapping screws, and when there are tens and hundreds of them, you cannot do without a screwdriver. If you plan to work a lot where there is no close outlet (when building a house or garage on a new site), a screwdriver, besides an electric one, is simply necessary.
In order not to buy a bunch of tools and not spend a lot of money, you can purchase universal tools. In our case, a drill and a screwdriver can easily be replaced by one - a cordless drill - a screwdriver. As an example of a good tool for a home craftsman, we recommend considering one of the Bosch models, namely the Bosch GSR 1440-LI cordless drill driver.
For this type of tool, the main purpose is, of course, the tightening of self-tapping screws and screws, and the drilling function is essentially additional. All the same, the power is not the same and it is not advisable to use it constantly as a drill.
Let's start with the price. As of May 2015, this model can be purchased at a price of approximately 5500 rubles. It's inexpensive enough for most people.
As already noted, this is a universal tool and is suitable for both screwing screws and drilling. This is possible due to the presence of a gearbox with two speeds. A lower speed is used for twisting, a higher speed for drilling. The screwdriver uses a 14.4 V lithium-ion battery with a capacity of 1500 mAh. This is a fairly large capacity, which is enough to work for a couple of hours.
Given the fact that there are two batteries in the kit, while you are working, the dead battery will already be charged. This allows you not to interrupt work to wait for the battery to charge. A large capacity is especially needed for those who will be engaged in roofing work. Screwing roofing screws into wood, and even more so into metal, requires a lot of energy and it is precisely this capacity that is required in these works. Also note that this type of batteries does not have a memory effect, which allows you not to be afraid that the battery will not be fully charged. Battery charging time is no more than 30 minutes.
The weight of the screwdriver cannot be called small, especially if you work for several hours, but this is precisely because of the batteries with a large capacity.
The Bosch GSR 1440-LI screwdriver has an ergonomic handle that is typical for all Bosch tools. Thanks to the anti-slip pad, you will have a good grip on the tool even if your hands get sweaty on a hot summer day. Thanks to the keyless chuck, changing drills or bits is very easy and fast. The diameter of the chuck socket is quite suitable for all kinds of drills and bits that the master may need.
It is also worth noting that the Bosch GSR 1440-LI drill driver has all the necessary protection and safety devices: stark button lock, battery overload protection, battery deep discharge protection, and of course the engine brake.
For ease of use, the tool is sold together with a special case, which conveniently accommodates the screwdriver itself, as well as the charger and rechargeable batteries.
