Drill and screwdriver: what's the difference?
The main task of the screwdriver is to twist and unscrew small screws and bolts. It can also perform the functions of a drill. Unlike this tool, the drill can only serve its intended purpose, that is, make holes. Many people think that these two units are practically the same, but this is misleading.
For example, when screwing screws with a screwdriver, when testing large loads, the cartridge begins to scroll. This is done with the purpose of not causing deformation of the faces on the self-tapping screw. Also, the screwdriver has a low rotational speed, in contrast to the electric drill. That is, when you remove the finger from the trigger, the screwdriver cartridge immediately stops, the drill is still spinning for a while.
Tip! It is more profitable to buy a screwdriver if drilling work is supposed to be done, because the drill requires alterations so that it can perform the work of tightening the screws.
Both tools are divided into two types, depending on the type of power: working from the network and battery. Pros and cons are obvious. The first type is completely dependent on the location of the outlet, and the batteries, although they give freedom from it, but constantly require recharging.
Also important differences are in the level of the tool, because there are household and professional. So, if the work involves small short-term loads, then there is no sense in taking a professional tool. As you can see, the difference between a screwdriver and a drill is quite large, and this should be taken into account when selecting tools.
How to choose a network drill?
For domestic purposes, the best option is a drill with a screwdriver function. Such a tool has a torque adjustment, which is important for masters working with materials of different densities: when the resistance changes, the rotation transfer automatically switches. This leads to the fact that the slots of the screws do not wear out. Also, this knob allows you to switch the work to drilling, as a result of which the torque is transferred to the drill bit. For this function, a screwdriver with a maximum speed of rotation of up to 1200 rpm is ideal.
Another very important function is the reverse, which makes it possible to rotate the nozzle in both directions. In addition, if the drill is stuck during operation, then, by switching the reverse, the operator will easily reach the jammed element. A clear answer to the question, a drill-screwdriver, which is better for home use - no, but more convenient is a tool on batteries. It is better to take such a screwdriver immediately with two batteries, since while one is involved in the work, the second can be recharged.
Tip! The best type of battery is a lithium-ion battery, since it is light and powerful enough.
Altering with your own hands
Having dealt with the difference between a drill and a screwdriver and for what purpose they are intended, you can ask how to make a screwdriver out of a drill, and is it even possible? Yes, it is possible to make a screwdriver out of a drill after certain alterations. We work in this order:
- The tool is taken and the battery is removed;
- A cable with a section of 2 x 1.5 mm is soldered to the contacts, and the contact block is filled in place of the battery with epoxy resin;
- An adapter is made, which is connected to the battery( it is necessary to connect to the network very carefully because of the high speed of the motor when operating from the network).
Note! For operation from the mains, the power supply must be at least 4 amperes. In this simple way, you can turn a drill into a screwdriver. But it's better to buy a tool with this function, because it's so much more reliable. As they say, why reinvent the wheel, if it already exists.
