It's possible to pick something up for as little as £10 from some online outlets, but we'd suggest avoiding the really budget stuff, as the screw bits tend to break or round screws, the torque output generally isn't enough to tackle most jobs and the batteries don't last.
How to choose an electric screwdriver?
It is important to pay particular attention to the screwdriver’s efficiency, especially if it needs to be used intensively.
The screwdriver’s head is fitted with a bit holder that might be magnetic or has a rapid release system. The bit holder makes it easy to rapidly insert the correct bit for the screw head.
The tightening torque is another point it’s important to consider. A high tightening torque means a strong screwing force. The higher the tightening torque, the easier screwing will be, even in hard material.
The tightening torque is directly linked to the power of the screwdriver. For mains powered corded electric screwdrivers, that power depends directly on the power of the motor. This varies between 450 and 705 watts.
For cordless electric screwdrivers, the power is linked to the battery voltage. This can go from 3.6 volts (V) to 18V for the most powerful ones.
For cordless electric screwdrivers, a high voltage allows for a longer battery life and avoids having to recharge the batteries too often. Certain electric screwdrivers are called impact electric screwdrivers: they are used for intensive screwing/unscrewing.
The rotation speed is an essential element, especially if you need to use your electric screwdriver regularly: corded electric screwdrivers generally have a higher speed of rotation than cordless ones.
Generally, electric screwdrivers only have one rotation speed. For corded electric screwdrivers, this is between 3,000 and 6,000 rpm (rotations per minute) and for cordless electric screwdrivers between 180 and 450 rpm.
For impact electric screwdrivers, the speed is indicated in counts per minute: it is between 3,000 and 50,000 cps/min.
