What Is An Electric Screwdriver?

An Electric Screwdriver is just like a normal manual screwdriver, but it is fitted with a motor that revolves bit heads to fasten & unfasten the screws, instead of your hand.

The Electric Screwdriver, as the name indicates, works on electric power which can be provided by connecting a battery ( in cordless ones ) or attaching the cord ( in corded ones ) into a power plug.

Are Electric Screwdrivers Any Good?

Yes, Electric Screwdrivers are good from manual screwdrivers in 3 ways;

 Manual ScrewdriversElectric Screwdrivers
 

Fatigue

●      Need human force, so workers get fatigued very easily and less work will be done.●      Work on a motor, workers only need to press a button, so no hard work & least fatigue. More work can be done.
 

 Time

●      When turning a screw by hand, takes a lot of time, which can cause a loss of a lot of money, especially in production industries.●      Turning a screw with an electric screwdriver is very fast. In industry electric screwdrivers can increase production rate by many folds & earn you huge profits.
 

 

 Accuracy

●      Fastening a screw to the right value is very necessary to avoid accidents. But screwing properly with your hand is not 100% accurate, especially when you have a lot of screws to tighten.●      Electric screwdrivers have an adjustable automatic off feature, which can stop the motor when the right fastening value is reached. So, 100% accuracy almost all the time.

How Does A Power Screwdriver Work?

In order to understand the working principle of Power Screwdrivers, let us first know their basic parts;

  • Power Source ( Battery or Electrical Plug )
  • Motor
  • Gear Box
  • Chuck
  • Bit

a) Power Source

Every Electric Screwdriver needs electrical energy to run its motor. The motor can be brushed or brushless depending on Power Screwdriver quality. The electric energy can be provided in 2-ways depending upon the model;

  • By Battery, which can be recharged
  • By connecting the Power Screwdriver directly to a live electric switch with a Cord

The power source is connected to a motor.

BATTERY OR PLUG, POWER SOURCE FOR ELECTRIC SCREWDRIVER
BATTERY OR PLUG, POWER SOURCE FOR ELECTRIC SCREWDRIVER

b) Motor

When you connect a power source to Electric Screwdriver & press the start button, the electricity runs through the motor which converts electrical energy into rotational mechanical energy, which means the motor drive shaft starts revolving.

The motor is connected to a gearbox.

ELECTRIC SCREWDRIVER MOTOR
ELECTRIC SCREWDRIVER MOTOR

c) Gear Box

A gearbox is present between the motor & Chuck. The purpose of a gearbox is to control the torque and speed of the motor driveshaft for the chuck. Depending on the model, many good-quality Electric Screwdrivers allow the user to change the torque/speed of the chuck when needed.

GEAR-BOX POWER SCREWDRIVER
GEAR-BOX POWER SCREWDRIVER

d) Chuck

A chuck is simply a special clamp that is used to hold bits. The gearbox box rotates the chuck, which in return rotates the bit which is connected to it, and finally, the bit turns the screw.

KEYLESS CHUCK CORDLESS SCREWDRIVER
KEYLESS CHUCK CORDLESS SCREWDRIVER

You can change the direction of rotation of the motor, which will finally change the revolving direction of the bit. So, you can rotate the screw in whatever direction you want for fastening or unfastening it.

How Long Does It Take To Charge A Screwdriver?

The charging time will depend upon 2 factors;

  • Battery Capacity
  • Charger Speed

a) Battery Capacity:

Electric screwdrivers mostly come in battery capacity from 600 mAh ~ 8000 mAh. The more the battery capacity, the more time it will take to charge it.

b) Charger speed

Charger speed is also a very important factor in determining how fast you can charge your screwdriver battery.

For example;

  • A Normal charger will take 2 – 3 hours to charge an 18 V / 2 Ah battery.
  • A Fast charger will take only 30 mins to charge an 18 V / 2 Ah battery.
WIRELESS CHARGER SCREWDRIVER

How Do I Choose The Right Electric Screwdriver?

When buying an Electric Screwdriver, you must consider the following factors;

  • Usage
  • Power
  • Shape
  • Bits Needed
  • Smart Features
  • Battery Capacity
  • Rotational Speed
  • Corded Vs. Cordless
  • Brushed Motor Vs. Brushless Motor
  • Accessories
  • Price
  • More…

a) Usage

If you are gonna use your Electric Screwdriver all day, buy a premium quality & sturdy one, but if you are gonna use it for home, then you may buy an average one.

Daily Usage Hours
Daily Usage Hours

b) Power

Usually, an Electric Screwdriver comes in 0.01 Nm ~ 180 Nm torque values. Higher torque means more power, which means easily screw will be fastened/unfastened.

But it does not necessarily mean that higher torque is always good. For example, if you are gonna use it on a PCB on a small screw, then you will only need a very small value of torque for safe work.

POWER ELECTRIC SCREWDRIVER
POWER ELECTRIC SCREWDRIVER

c) Shape

Electric screwdrivers usually come in 3 shapes;

  • Straight Shape
  • Gun-like Shape
  • Right-angle shape
  • More…

Straight shape screwdrivers are best when you are screwing from up to down or in deep spaces. Gun-shaped screwdrivers are best if you need more grip. Right-angle screwdrivers are best for hard-to-reach narrow spaces.

Some companies also offer all-in-one shape Electric Screwdrivers, which have a head that can be tilted and comes with a gun handle accessory, so you can convert a straight shape screwdriver into a gun-shape screwdriver.

DIFFERENT SHAPES POWER SCREWDRIVER
DIFFERENT SHAPES POWER SCREWDRIVER

d) Battery

Electric Screwdrivers mostly come in battery capacity from 600 mAh ~ 8000 mAh. More battery capacity means more running time, which is good but more capacity also means more cells in the battery which means more weight.

So when choosing a battery always look for more time but avoid too much bulky battery choice because you will have to carry it, which will make you fatigued easily. Usually, 2000 mAh is best in terms of weight and usage time.

Also, battery voltage is very important. More battery voltage means more power. Cordless Electric screwdriver mostly comes in a battery voltage range from 3.6 V ~ 20 V.

Finally, choose whether you want a Li-ion, Ni-MH, or Ni-Cd battery. The Li-ion battery is the most advanced and the best, but it is also costly.

BATTERY OPTIONS

g) Rotational Speed

Electric screwdrivers mostly come in rotational speed from 12 rpm ~ 6000 rpm.

More rotational speed means quicker a screw will be fastened. So, for daily life usage, buy a screwdriver with at least 500 rpm ~ 3000 rpm. But more speed is not always the best, especially in screwing very big screws where you need more torque.

SPEED POWER SCREWDRIVER
SPEED POWER SCREWDRIVER

h) Corded Vs. Cordless

Corded Electric Screwdrivers are light in weight, can be used for unlimited time.

While Cordless screwdrivers are no doubt bulky and their usage time depends on battery but they can be used where no electric plug is present, they are not bound to a wall like corded ones, as they have no wire so you will not have to worry about the wire being getting in the way, and finally, they operate on battery not on live current so you will not have to worry about getting a shock.

If buying a cordless screwdriver, consider what charger speed you want, normal/fast, and do you want a wireless charger or not.

How long Does An Electric Screwdriver’s Battery Last?

An Electric Screwdriver battery lasting time ( usage time ) will depend upon battery capacity and working conditions.

More battery capacity means more time you can use your screwdriver before the battery will get empty. Usually, a 2.0 Ah battery can power a screwdriver for 40 minutes of continuous use.

Environment conditions, such as too hot or too cold, and working conditions like you are overloading the screwdriver, will cause the battery to drain faster than normal. You can not control the environment but never overload the screwdriver.

Always buy a high Ah, high voltage, and high power screwdriver, if you want your battery for many hours.

What Are The Different Types Of Screw Heads?

There are many kinds of Screwheads, such as;

  • Torx
  • Bristol
  • Square
  • Tri-Wing
  • One-way
  • Polydriver
  • Hex or Allen
  • Pentalobular
  • Slotted ( SL )
  • Triple Square
  • Spanner Head
  • Pozidrive ( PZ )
  • Philip Head ( PH )
  • More…

Most of us know only Slotted, and Philip head screws. You can see the most used Screwheads below;

FAMOUS SCREW HEADS SHAPES
FAMOUS SCREW HEADS SHAPES

Why Do We Have Different Types Of Screw Heads?

We have different kinds of Screwheads due to 3-main reasons;

  • Cost
  • Torque
  • Security
  • Self-Centering

a) Cost

The cheapest are slotted heads, then comes Philip head, then square, and so on. Usually, the more complex the shape, the pricier it will be.

b) Torque

The more sides a screw has means the more torque it can handle. Slotted heads have 2 points of contact so they can not handle high torque and get stripped easily. Philip screws have 4 points of contact but they are not deep enough so they can handle average torque. While Square, Hex, Torx, and other more sides screws can handle high-torque values.

c) Security

Some companies develop their own screw head shapes to prevent people from tampering with the products on which they are used. This method is only good for some time because people develop tools for those screws too and sell them. But those tools will not be easily accessed by everyone, so this method does provide some security for the long-term but only against normal people.

d) Self-Centering

Slotted head screws do not have the self-centering ability with the bits, so they can not be used in automated machines, while Philip and other complex shapes screws have a self-centering ability which makes them ideal to use in automatic machines.

In summary, there are so many screw heads because companies want to manage cost against need (torque/security/ease of use ).

How Many Volts Do I Need In A Cordless Screwdriver?

Usually, Cordless Screwdrivers come in a Voltage Range of 3.6 V ~ 20 V.

The thumb rule in choosing the voltage of a Cordless screwdriver is the heavier the work is, the more voltage you will gonna need.

For example, if you are choosing an Electric Screwdriver for home use, you may choose a 3.6 V, 4.8 V, 9.6 V, or other low voltage versions. But if you are doing work in the automobile industry, then it is best to get an 18 V or 20 V screwdriver.

Plus, more voltage means a more efficient screwdriver electrical system, which means less loss of current in the wires and more battery life.

DIFFERENT VOLTAGES IN SCREWDRIVER
DIFFERENT VOLTAGES IN SCREWDRIVER

Are All Cordless Electric Screwdrivers Battery Powered?

Yes, all Cordless Electric Screwdrivers are Battery Powered because Cordless means no cord, which means you cannot connect it with an Electrical Plug directly for power. So, you will have to power with another way which can only be a battery.

How Do You Maintain A Screwdriver?

Maintaining your Electric Screwdriver will surely increase its life manyfold.

You can maintain a screwdriver in the following ways;

  • Clean it regularly.
  • Do not overheat it.
  • Lubricate it if needed according to manufacturer guidelines.
  • Inspect bits for cracks, if present, replace damaged bit(s) asap.
  • If after turning on, but do not move due to low torque, then switch off the screwdriver, in under 10 seconds, to avoid damage to the motor.
  • If Screwdriver shakes unusually, bits fall off the chuck easily, speed is not right, or anything else mechanical happens, repair your screwdriver asap.
  • If corded, check the cord regularly for any kind of damage to avoid electrocution. If cordless, do not cause the battery to overheat, or it may get damaged beyond repair, and do not drain it completely before recharging.
  • More…

Why Do Electricians Carry So Many Screwdrivers?

Electricians use so many screwdrivers due to 4 main reasons;

  • Mostly use manual screwdrivers whose heads are fixed, but there are many screw heads shapes. So, they need many different head screwdrivers for different shapes of screws.
  • There is more than one person to use screwdrivers at one time.
  • There are many sizes of screws, so they need many sizes of screwdrivers.
  • They need to keep extra screwdrivers if one breaks, gets lost, somebody loans it, or e.t.c.

But now New Electricians keep only one Electric Screwdriver kit with them, which contains most sizes & shapes of bits ( which can be attached to the screwdriver head when needed ) for different kinds of screws. So, now there is no need to carry so many screwdrivers, just buy one Electrical Screwdriver kit, and make life easy.
