3 Things You Should Know Before Buying a Cordless Screwdriver


The type of cordless screwdriver you should buy is determined by the application. Will you, for example, use it regularly for construction work? Renovations or new construction? Do you work in a mechanical shop? Are you looking for furniture? On a production line?Get more news about power screwdrivers brushed motor,you can vist our website!

The frequency of usage of the screwdriver is another significant factor to consider. Remember that it is preferable to buy a corded model if it will be used all day. However, if it will only be used for 2 or 3 hours each day, a cordless model may be preferable, with an extra battery and charger kept nearby. It’s critical to pay close attention to the screwdriver’s efficiency, particularly if it’ll be used frequently.
Another crucial factor to consider before going on and buying a cordless screwdriver is the tightening torque. A strong screwing force is indicated by a high tightening torque. Even in hard material, the higher the tightening torque, the easier it is to screw.

The power of the screwdriver is related to the tightening torque. The power of mains-powered corded screwdrivers is directly proportional to the motor’s power. The power output varies between 450 and 705 watts. If it is powered by an external transformer, the higher the supply voltage, the more powerful the screwdriver will be. The voltage of the battery determines the power of cordless screwdrivers. For the most powerful, the voltage varies from 3.6 volts (V) to 18 volts (V). With a cordless electric screwdriver, a high voltage allows for longer battery life and reduces the need to recharge the batteries as frequently. Impact screwdrivers are designed for heavy-duty screwing and unscrewing. Screwdrivers built for heavy-duty screwing and unscrewing are known as impact screwdrivers.

The rotation speed is critical, especially if you’ll be using the best cordless screwdriver you are buying, frequently: Notice that the corded screwdrivers rotate at a faster rate than cordless ones. Electric screwdrivers typically have only one rotating speed. This is between 3,000 and 6,000 rpm (rotations per minute) for corded screwdrivers and 180 to 450 rpm for cordless ones. The speed of impact screwdrivers is measured in counts per minute, and it ranges from 3,000 to 50,000 cps/min.
Lithium-ion batteries are used in the majority of cordless screwdrivers. These are the batteries that have the finest attributes to date: they are lighter and retain a charge longer than other types of batteries. The larger the battery’s capacity, the more self-sufficient it is. There are three varieties of cordless screwdriver batteries: those that are less than 1.5Ah (ampere hour), those that are between 1.5 and 2Ah, and those that are greater than 2Ah.
