What torque the screwdriver needs. What power to choose a screwdriver. Features of choice

GEARWRENCH 89620 Torque Screwdriver Review [10 to 50 in/lbs]

What is the torque of a screwdriver and what it should be

If you need to tighten a screw or bolt, the screwdriver will help to speed up the process. This is a compact device operating from a network or a battery, has a power sufficient to work with fasteners. An important characteristic of the tool is considered the torque of the screwdriver.

It is to this parameter that you should pay attention when choosing a specific tool.

How to choose the right screwdriver for the home. Battery screwdrivers

This type of instrument is more widely used. Such devices are obtained from batteries, the capacity and time of charging which can vary significantly.

  • Independence from the presence of electricity and the location of the outlet, which gives freedom of action. Work can be performed at a height, in hard.To.Reach places, and almost in the field, and the wires will not be confused underfoot;
  • The scope of use is wider, which follows from the autonomy and mobility of the tool.
  • Dependence on the level of the battery charge, the need to constantly monitor this parameter and periodically charge batteries. Experts recommend taking a spare battery together with the battery screwdriver: while one is charging, the second works. It is preferable to choose batteries that are quickly charged;
  • In power, the battery tool loses to the network. Torque may not be enough to work with solid materials, but there are exceptions here. Professional battery screwdrivers are quite powerful and reliable.

Professionals know that choosing a battery screwdriver is even more difficult than a network, because it is necessary to take into account not only directly the functions of the device, but also the features of the battery.

The first thing to pay attention to is the type of battery:

  • Lithium-ion batteries, Li- Ion. This is the most popular and modern type of battery, used everywhere, not only in screwdrivers. Of the advantages, low weight, sufficient power, lack of memory effect, a large resource of charge/discharge cycles (about 3,000 or more), high charging speed. Of the minuses is a relatively high cost, so this is a good option for constant, but not one.Time work. Such a battery is not designed to work in the cold. In order for the battery to serve as long as possible, it is better not to discharge it by less than 15% and not charge more than 90%. Service life is about 3 years;
  • Nickel-cadmium, Ni-CD. Have high resistance to low temperatures and voltage surges. On the other hand, they have a pronounced memory effect, so it is better to discharge such a battery completely and completely charge, so as not to reduce its capacity. The battery withstands about 1000-1500 charge/discharge cycles, but it charges for a long time-about 7 hours, so it is better to have a spare battery. The weight of the battery is significant, but it costs the cheaper. Service life is about 5 years;
  • Nickel-metallhydridid, ni-mh. Such batteries become more and more popular, differ in slight weight, low resistance to low temperatures, the effect of memory is unexpressed. A big plus is the minimum self.Discharge, and the minus is the price;
  • Lithium-polymer batteries, Li-Pol, are used in screwdrivers is extremely rare. These are capacious, but not very durable batteries.

How to choose a screwdriver battery advice. Network or battery

Depending on the method of obtaining food, all screwdrivers are divided into network and battery. The first option receives power supply to the network cord, they are much more effective due to constant power and due to the lack of need to monitor the value of the charge. But, in comparison with battery screws, they cannot be used in places where there is no 220 V electric network, they also have a fairly large weight. A separate disadvantage of network screwdrivers is nutrition from a dangerous voltage level, while batteries, feed on low voltage and do not threaten the working in the event of breakdowns.

Battery screwdrivers are mobility. They can be used in places where there is no power supply at all or where to carry a bulky tool is inappropriate. Such models differ relatively small weight and dimensions, but they are more expensive and can be discharged at the most inopportune moment. The main parameter to pay attention to, when choosing a battery screwdriver is the type of its battery and its capacity.

Types of batteries

Types of batteries determine the most important parameters. The duration of the screwdriver, the need for a complete discharge, the duration of the charge, the service life and the price of the electric tool itself. Today there are four types of batteries:

“ TORQUE SCREWDRIVERS “ An Electrical Code Requirement( NEC Article 110:14 )

  • Lithium-ion, is indicated as a Li-Ion battery-relative to others holds a charge for a long time, also quickly accumulates it and does not require complete discharge. To date, this is the most effective option for construction and electrical operations, its main disadvantage is the high cost, so for single work screwdrivers with such a battery is better not to choose.
  • Lithium-polymer, is indicated as Li-Pol Battery-has the largest capacity among batteries for screwdrivers, but it fails faster than others.
  • Nickel-cadmium, are designated as NI-CD batteries-differ in the largest service life, about 5 years, in comparison in others about 3 years. This option is also characterized by low cost. The disadvantages include a long charge and the need for a complete category.
  • Nickel-metallogidride, are designated as NI-MH batteries, characterized by a good battery capacity, unlike other models, have a much lower weight with the same battery capacity. Due to what such a battery screwdriver has smaller sizes, but also much more cost.

Using a screwdriver for mixing building mixtures: torque

Screwdrivers are used in construction not only for installation, but also for stirring various mixtures and solutions. To do this, a special mixer is inserted into the tool cartridge. In this case, the torque must also correspond to the nature of the work performed. When mixing liquid solutions, you can use small values ​​of rotating force.

torque, screwdriver, needs, power

However, when acquiring a power tool, it is necessary to choose a rotating action sufficient to work with viscous mixtures. In this case, the professional model of the screw.Vert with manual or electronic control is more appropriate. The presence of a lowering transformer will make it possible to work not only with viscous, but also with liquid mixtures. Due to low voltage.

Having carefully read the article, the user will be able to choose the optimal model of a screwdriver for both repair work in the household and various assembly or construction operations in production.

Summary

Answer the question: which is better to choose the optimal torque for a screwdriver is definitely impossible. The future owner must select him based on his needs.

Examples of the best models of different groups of a screwdriver indicating the size of the rotation moment:

The best models for use as an ice discovery:

Some manufacturers in the technical passport indicate two types of torque: soft and tough for working with appropriate material. You also need to remember that this equipment is classified into battery and network types.

What is the difference?

Shock screwdriver opens up access to greater power when moving from low to high speed. Drill gives you access to most of your power in both modes. However, to transmit a greater torque when necessary, this power is selected from the speed of rotation. When the speed is more important, you can choose a higher speed mode with a reduced torque.

The best screwdriver for winter fishing
