It is used in repair work in construction, it is indispensable to tackle a host of domestic issues (assembling furniture, cornices, shelves, cabinets, etc.) The main functions of the screwdriver - a screwing and unscrewing any fastenings and details. Also it can be drilled using a wooden, metal surface, or cut thread. To date, the power tool market is quite large and varied, so it is not surprising that more and more customers are given the main issue: how better to buy a screwdriver?

types of screwdrivers

Depending on the characteristics and purpose screwdrivers can be divided into intended for professional activities or household use, running on AC power or batteries.

The main purpose of the screwdriver - screwing or unscrewing the fasteners

Consumer or professional tool - for and against

Like any other tools, screwdrivers are divided into professional and consumer. However, not all the characteristics that have professional tool, will be in demand in the domestic circulation. But the price can vary greatly in favor of the domestic models. For example, for tightening screws, nuts and bolts enough torque to 15 Nm, while the professional models are available with a mark of 130 Nm. If you want to drill a fairly firm surface - household tools will not be enough.

The next thing to note - the motor shaft. The number of revolutions at prof. Tool 1200-1300 rpm, while the domestic options can only 400-500. And of course, it is important how often you plan to use a screwdriver. Powerful professional models suitable for frequent use and larger volumes of work. If, however, plans to use the screwdriver is not more than 1 time in 2 months - can safely opt for the available amateur versions of decent quality.

Professional tool differs from the duration of the work of amateur models and increased functionality

Mains or battery? What better and more practical screwdrivers

Another difference that separates screwdrivers into two basic types - power principle: AC or battery. The first are heavy, and their work is only possible if you have access to an electrical outlet. This makes it impossible to use them in the construction and maintenance of those facilities to which electricity is not let down. Availability of the power cord gives a lot of inconvenience in use, particularly when it comes to working at heights. Such a tool is less mobile.

Cordless Screwdrivers much easier, they are self-contained and allow you to work with them in almost any conditions. Try to understand - how to choose a cordless screwdriver?

The main drawback - the content of the toxic and allergenic substances - cadmium. Nickel-cadmium batteries have a low memory effect, i.e. reduce the capacitance after each charge. Energize it can not be long until the previous charge it will not be fully utilized.

Charging time professional models is about an hour everyday - several times more

The hybrid battery (nickel-metal)

The advantages of this type of battery: it is quite light in weight, has a large volume, is not discharged even if not used for a long time (the proportion of discharge for a month without using is only 1%). Quite low memory effect. Among the shortcomings: not able to be charged more than 500 times.

Another common cause of failure is breakage of the tool for the screwdriver bit. What better, more practical and durable - it depends on many factors. Chief among them - the material from which the nozzle. Steel is the most durable R7 - R12 c titanium nitride or chrome-plated. Also affects the durability bit processing method. The most common are milling or forging.
