If possible, hold the cordless screwdriver in your hand before you purchase it. Consider the following when handling the tool:
Do you have a firm grip on the handle?
It’s important that you have a firm grip on the handle when using the cordless screwdriver. Some models will have a rubber grip, others will just have contours in the tool’s casing.
Can you reach the controls comfortably?
It’s important that you are able to reach the speed control trigger and pull it all the way in easily.
The forward/reverse switch is usually located above the trigger or on the back of the tool, so check that you can reach this easily with your thumb or forefinger.
Does the tool feel well balanced?
A well balanced tool is important if you’re going to be using it for a long time, and could prevent excess strain on your arm and wrist.
Ensure the front part of the tool does not feel too weighty.
How heavy is it?
A cordless screwdriver’s weight shouldn’t necessarily be the reason you do or don’t buy it. A tool can be lightweight and compact but it’s no good if it doesn’t have enough power to complete the task at hand!
However, weight should be a consideration. A tool may have the required power but its no good if it’s so heavy you can only use it for a very short period of time.
Generally, the more torque and speed a cordless screwdriver can deliver, the heavier it will be. This is because a larger battery and motor is needed to power the tool.
The heavier the tool is, the more strain your arm and wrist will be under when working.
Most cordless screwdrivers weight around 500g. That’s about the weight of a 500ml bottle of water.
