What is better to buy a screwdriver for home + Video

When there are skilled male hands in the house, it means that there will be someone to assemble a new wardrobe, hang up the shelves, and screw the screws with self-tapping screws. But only sometimes these screws or nuts have to be wrapped so much that after an ordinary screwdriver, hands like cast-iron ones get tired. But with a screwdriver it will be possible to do all this without much effort. In order to optimally determine what kind of screwdriver to buy for the home, consider the characteristics of this device.

What parameters should have a good household screwdriver

This device will be needed when you need to either screw or unscrew screws, bolts, nuts or screws. By fitting the drill bit, you can make a hole (but only a small one). If you need to drill a large hole, then take a drill assistants.

The main parameter of the screwdrivers is the torque. It is on this indicator that one should pay attention when studying the instrument passport.

What does the torque value mean?

This parameter shows which surface the tool can handle without problems. The less torque, the less dense should be the material into which you need to screw the screws. For household tools enough torque from 10 to 20 N · m. To protect the motor, its coupling is equipped with a special ratchet. Thanks to it, at loads that exceed the permissible threshold (maximum torque), the motor shaft begins to slip.

In a quality screwdriver, there is always a device that limits this maximum torque. It is made in the form of a ring, and is located on the engine axis immediately after the chuck. The safety clutch will protect the nozzle from wear, and the screw will not allow too deep into the material.

The limiter can be adjusted. Steps of adjustment is from 5 to 22 - better is more than less.

Select the type of power

The screwdriver can be stationary, powered from an ordinary outlet, or battery. The last option is more mobile, more compact and more convenient. But he also has "pitfalls". If the screwdriver is not used for a long time, then its batteries die little by little. It often happens that this screwdriver is lying, and it can be used once in 2 months. Batteries are discharged, they do not receive timely charging and gradually lose their capacity. Therefore, it may be worthwhile to take a closer look at a not so convenient network device with a long cord - after all, it will not fail.

Minus - the requirement of constant charging and quick failure of batteries.

Network screwdrivers will be more weighty and cumbersome than their cordless counterparts. But on the other hand, they can be stored for an arbitrarily long time, and there is no need to worry about charging. A long cord will make it possible to do the necessary work, and if it is not enough, the extension cord is at your disposal.

The downside of network models is the high price. But with this choice, as now, you can find quite a budget network screwdriver.

When choosing between these two types of power, think about the conditions in which you will need to operate the device and make the appropriate choice.

If the batteries are, then what

The power of the device is determined by the nominal voltage of the battery, and the duration of the work - by its capacity. Household screwdrivers have this indicator at the level of 1.2 - 1.5 Amp-hour. Further, we note that these same batteries are of three types.

  • Nickel-cadmium-type batteries are everywhere being discontinued, since the cadmium contained in them is very harmful to humans. It can cause allergies. But in stores, devices with such a battery are still being sold. This battery is frost resistant, and can be recharged up to a thousand times. The main disadvantage is that it has a memory effect, which reduces the charge from one time to another.
  • Nickel-metal hydride batteries are very lightweight. Recharge ability - five hundred times.
  • Lithium-ion type batteries are high-quality, have no memory effect, last for a long time. Unfortunately, afraid of frost.

Charger type

Professional devices usually have an excellent charging device in a set that can do its job just for hour. Amateur models charge the battery three or even five times longer. However, you decide - after all, professional charge models are much more expensive. In my opinion there is no need to overpay, so you can opt for a simple charger.

Rotational speed

For high-quality screwing in of the screw, a speed of no more than 500 rpm is sufficient. 1300 rpm is required for drilling, no less. The best option - the presence of a speed regulator.

Choosing a brand of screwdriver manufacturer

A huge selection of models and firms can confuse an inexperienced buyer. He has absolutely no idea what kind of screwdriver to buy for the home. They are so similar to each other, except that the colors and designs are different - this is the first impression.

If the amount spent does not play a special role for you, fix your eyes on the top three most popular brands. These are Makita, Hitachi and Bosch. Well, yes, you will have to overpay for a certain name, but the tool will please ergonomics, functionality and durability.

If the device is bought only for small home repairs, you can save. American black screwdrivers showed themselves quite well. Decker. Or you can buy a domestic Interskol - this is quite a “workhorse”.

Summing up and deciding on the parameters for a household screwdriver

  • When buying a screwdriver, choose a reliable, trusted manufacturer.
  • The torque value is not less than 10 Nm.
  • Engine rotation speed is about 400-500 rpm.
  • Operating modes - two. This is twisting and drilling.
  • Presence of reverse.

Depending on our requests, we take a model that works either from the electrical network or portable. What is good and what is bad in each of them, it has been said above. Important: if you buy a battery device, then we look for the included spare battery. A couple of tips when buying such a device:

  • It is best for a home to take a model with a lithium-ion type battery, since such a battery has no memory effect at home, it will last longer. This is because at home you will not use the device all the time, and going into a long discharge of nickel-cadmium-type batteries is fraught with their rapid failure.
  • The battery voltage should be between 10 and 14.4 volts.
  • If two different screwdriver models have batteries with the same voltage, select the charge value (unit of measure is Amp-hour). Buy a model that has this parameter more.
