Battery-powered screwdriver: what you need to know

When repairing a car, there is often a necessity to mount or dismount threaded fasteners. Power screwdrivers help to fulfil this task much faster. They are especially effective when dealing with large fasteners.

What are the types of power screwdrivers?

• Straight. These devices are characterised by a high tightening torque.
• Angular. Handy when fasteners are in hard-to-reach places.

Items that can be found in the catalogues differ by the type of the drive. It can be:

• Electric. These tools can operate without any other additional equipment. They are divided into the following categories:
  • With a battery. Useful when there are no power sockets around. As a rule, modern models are fitted with lithium-ion batteries. These power sources are lightweight. They can be recharged when it is necessary not only after they鈥檝e become flat.
  • Mains-powered. Suitable for doing loads of work. Are considerably inexpensive.
• Pneumatic. These devices require a compressor. They are light; thanks to this, workers get tired less while working. It isn鈥檛 dangerous to use then in conditions of high gas contamination and humidity.

Making a purchase online, please, pay your attention to additional functions these tools might have. For example, they can feature an impact mode or have a flashlight (torch).

Operating principle

Unlike a screw gun which features a similar design, this tool doesn鈥檛 have a keyless chuck. Instead of it, there is a bit adapter. The tool powered by mains or battery has an epicyclic gear train that transmits torque from the electric motor to the spindle. In order to adjust the torque, the gear train is equipped with a coupling. The device powered by an air compressor is equipped with a pneumatic motor. In this case, the spindle rotates thanks to the compressed air supply.

Tips on using power screwdrivers

Read the manufacturer鈥檚 manual and follow the recommendations stated in it. Use only the devices that work properly. If the bit has worn-out, replace it with a new one. Only specialists must replace damaged cables. Start the device only when its bit is in contact with the fastener. Do not apply too much force.

Use a damp tissue or a cloth to clean the tool. Try to keep the device away from direct sunlight; prevent liquid and dirt from getting inside of it.
