Electric Screwdriver

Electric screwdrivers are handy for assembling flat-pack furniture when used in conjunction with a drill or combi-drill. They can be used with any bit (Phillips, Torx, Pozidriv, and so on), but for extended use, you’ll need a battery with a high Ah rating.

Important characteristics

The basics of choosing an electric screwdriver

Usage only on rare occasions

If you only plan on putting together five pieces of furniture over a year, a 3.6 V electric screwdriver with at least 1 Ah and 3 Nm will suffice. For ease of use and comfort, choose a compact, lightweight model.

  • a thermostat for setting temperatures and activating the immersion heater to heat the water;
  • an anode rod for corrosion resistance;
  • supply of electricity
  • a control panel;
  • (Optional) LED light
  • a dip tube to ensure that your water is evenly heated and circulated

Continual use

If you plan on putting together several pieces of furniture each week, go with a well-known brand and a high voltage and Ah rating model. If you don’t need much-tightening force, go for 3.6 to 4 V and tightening torque of 5 Nm, or 7.2 V, and at least 10-15 Nm if you do. However, keep in mind that a professional drill driver is probably better suited to your needs in the latter case.

The recommended battery capacity is 1.5 Ah (the most common value). This will allow you to work for more extended periods while also giving your electric screwdriver a bit more pep!

Electric screwdrivers' limitations

  • Make sure you don’t mix up an electric screwdriver with a drill driver or a combi-drill: the latter are multi-purpose power tools, while electric screwdrivers are built exclusively for assembling flat-pack furniture and tightening with low torque.
  • Look for a drill driver if you need a product with longer battery life and more torque. A drill driver is a hand-held power tool that falls somewhere between a drill and an electric screwdriver. It has more torque than a typical electric screwdriver.
  • Please keep in mind that an electric screwdriver and a drill driver are not the same things. Drill drivers are pistol-shaped and can exert a torque of at least 5 Nm, which is essential to note.

It’s worth mentioning that the proportion of titanium used by different manufacturers varies, affecting the bit’s quality and that diamond bits have a firmer grip.

When do you use an electric screwdriver instead of a drill?

An electric screwdriver is ideal if you need a tool for assembling furniture and don’t need a lot of torque.

These tools are small and compact, allowing for precise fastening, and can even be used in tight spaces like inside drawers.

 

Break open the piggy bank and invest in this mini hand-held power tool if you’re moving and have a half-dozen pieces of Swedish furniture to assemble! In this case, a drill driver or a combi-drill isn’t a good idea because their weight and features aren’t designed for this type of work.

Electric screwdrivers have several advantages.

If we haven’t yet persuaded you, consider the following benefits of electric screwdrivers:

  • Adjustable head for twisting the tool rather than your wrist;
  • Straight handle or pistol handle (on some models, both);
  • 450-gram average weight;
  • LED lighting for better control and visibility; ultra-fast recharging;
  • Torque adjustment settings

Voltage, rotation speed, amperage, and lithium-ion battery in electric screwdrivers

It’s easy to pick the right electric screwdriver. You won’t go wrong if you focus on the following criteria.

Amount of voltage

90% of electric screwdrivers have a voltage of 3.6 V, which should make your decision easier when choosing a model (the remaining 10 percent range from 4 to 7 Volts).

Rotational velocity

The rotation speed of an electric screwdriver is a carefully calculated balance of voltage and reduction ratio between 200 and 600 rpm without load.

Battery life and ampere hours

In short, the ampere-hour (Ah) rating of your electric screwdriver determines how long the tool’s battery can last. The battery will last longer if the rating is higher.

Li-ion batteries

Lithium-ion (Li-ion) batteries are used in most electric screwdrivers. This form of battery recharges quickly, is thin, and has no memory effect. Electric screwdrivers seldom use nickel-cadmium (Ni-Cd) batteries, which are huge, heavy, and have a memory effect. Both batteries must be recharged with a charging system that is compatible with them.

How much torque do you need from an electric screwdriver?

Put, torque is the force of tightening: the higher the value, the greater the strength of tightening—the unit of torque in Newton-meters (Nm). The torque values of most electric screwdrivers vary from 3 to 5 Nm, with some top-of-the-line models offering up to 20 Nm.

Torque values of 30 Nm or higher are possible with impact drivers (hand-held power tools that fall somewhere between an electric screwdriver and a drill/combi-drill). Higher torque makes the screwdriver simpler to use and helps you push screws through even the most difficult surfaces! Electric screwdrivers have torque settings that allow you to tailor the tightening force to the material you’re working with.

Additional features and options for electric screwdrivers

Additional features and options for electric screwdrivers

Other features and options available on electric screwdrivers include:

  • LED lighting, which is useful when you need to use your screwdriver in dark corners;
  • An adjustable head makes it easier to reach screws in tight spaces;
  • Two batteries, so you’ll still have a backup;
  • A high no-load speed expressed in revolutions per minute (rpm);
  • A storage bag or case to keep your accessories from being lost;
  • a belt loop or a lanyard;
  • It has lightweight.

If you require more, a drill driver should be sought.

After-sale service and warranty

Choosing a brand-name power tool, as with all power tools, ensures that you will receive excellent after-sales service.

The majority of manufacturers also have a one- to a two-year warranty.
