This versatile tool helps not only to tighten, but also to unscrew screws and screws, which often "stick" and do not lend themselves to a conventional "hand" screwdriver. A home screwdriver is more expensive than a regular screwdriver, but it justifies itself with significant savings in time and effort. In addition, some screwdriver models allow you to drill holes in a variety of materials.
Types of screwdrivers
Tools of this type can be divided into two main types:
- For professional purposes;
- For household purposes.
Professional models are chosen for frequent use. They have a high rotation speed - up to 1300 rpm, and a high torque - up to 130 Nm. This allows considerable effort to be developed and holes drilled in wood and even brick walls.
Household models opt for use from time to time. The rotation speed is less - up to 500 rpm, the torque does not exceed 15 Nm. This is quite enough to screw in a self-tapping screw or unscrew it, disassemble the lock, assemble furniture. For household work, the capabilities provided by household screwdrivers are quite enough. In addition, the cost of home screwdrivers is much less than professional ones.
How to choose a cordless or cordless screwdriver for your home?
Screwdrivers are divided into two main groups:
- Network;
- Rechargeable.
Both have their own strengths and weaknesses. Network models quite powerful, they can be used for a long time without fear that at the most crucial moment the instrument will suddenly turn off. It does not have to be put on recharge, which is especially important if you have to use the screwdriver for a long time. Also, you will not face a situation when you urgently need a tool - and you cannot use it, since the battery is discharged.
The main disadvantage of power cord screwdrivers for the home is the cord with which you are "tied" to the outlet. It will not work to carry out work where there is no electricity, and the front of the work should be as close as possible to the outlet. In addition, it is not always convenient to work when a long cord leaves the instrument.
Battery models in terms of power they are not inferior to network ones, and in terms of usability they are superior. Indeed, the cord does not come off the handle of the device, which can interfere with work, you can use the tool even in the absence of the mains.
The main disadvantage is the limited operating time, and, in addition, the need to charge the battery. If you decide to choose a cordless screwdriver for your home, you need to take into account that their work depends on the type of batteries.
- Metal-hybrid... Of the advantages, it can be noted that it can be used at temperatures below zero. Negative - full discharge is necessary before starting to charge again, otherwise the battery capacity and, therefore, its usage time will decrease over time.
- Nickel-cadmium. They can operate at low temperatures, in addition, they can withstand high currents during charging and discharging. The disadvantage is the same as for metal-hybrid ones: you need to completely discharge the battery before you put it on charge.
- Li-ion. This type of battery is the most powerful. Plus, they can be recharged without the fear of depleting their capacity. Minus - you can work only at positive temperatures. In addition, the price for screwdrivers equipped with lithium-ion batteries is significantly higher.
