How can You Determine the ‘Right Voltage’ Screwdriver?
Consider following things before purchasing an electric screwdriver:
- The purpose of using screwdriver: If you want to use the electric screwdriver for the domestic jobs like work on soft wood or plastic surfaces then such tasks are called light duty tasks. Such jobs do not require higher power. You can simply use a cordless electric screwdriver with a battery voltage of 4 V. You need a screwdriver with a battery voltage of 7V for walls and thick metals.
- The weight of the tool: The weight of the tool is not a big concern if you use it sporadically. Though for the frequent use, the cordless screwdriver should be lightweight so that your hands and wrist do not get strained. If you choose high voltage screwdriver then it will be heavyweight whereas low voltage drivers are lightweight.
- Budget: Want long running or short running driving tool? If you want high voltage, more battery capacity, long lasting battery life, and sufficient rotation speed then conspicuously you have to spend more. More you spend, highly integrated cordless screwdriver you will get. Hence, the efficacy and voltage of the screwdriver will depend upon your budget.
- The voltage range of battery: Higher the voltage, more powerful will be the screwdriver. High voltage screwdriver deals with the various types and sizes of screws and materials as well.

Moreover, its shape is appropriate that you can easily hold it for hours. The electric screwdrivers come in various shape with a different grip such as pistol, upright, etc. These machines come with a kit, which holds a variety of screws and bits. This makes your job easy.
- Require fewer maneuvers: If you are supposed to take away the screws back from the respective surface material by a manual screwdriver, then it totally sounds boring and tedious. Since the electric screwdriver performs well for “reverse action” or taking out the screw back, some cordless screwdrivers come along with integrated built-in wire strippers and benders. Thus single cordless electric screw drive is enough to deal with multiple jobs
- Enormous efficacy: The electric screwdrivers do not only drive screws rapidly but also they insert them inline with accuracy. It's prevailing drilling capacity makes the screws remained in their places for the long term.
- Highly adaptable: You can control during the job operation by adjusting speed. Hence alterable speed is good for the control and the efficacy of machine during work. Some electric screwdrivers get integrated by straight as well as pistol shape in one model only. Thus such screwdrivers are highly adaptable and versatile to deal with multiple job tasks.
- Money and time saver: An electric screwdriver comes with a kit which holds different shapes of grip. Thus electric screwdriver with multiple grip shapes performs each kind of job due to multi-positional grip shapes. It completes the job before time, and it is indeed cost-effective.
Which Specifications of Electric Screwdrivers Should You Take into Account?
1. Screwdriver torque
The amount of torque required to a machine decides the diameter of the screw, which can be tightened by it. Moreover, the surface you can work on also depends upon torque. The average screwdriver has 10-30 N/m range value of torque.
Such screwdrivers are appropriate for the small scale works. Whereas for the heavy duty works, torque value should be greater than 100 N/m. In latest crew drivers you can adjust the torque to deal with different type of screws at suitable force.
2. Rotation speed
Rotational speed gives the measure of the quickness and fastness of the machine. For the light duty jobs the rotation speed should be 450-550 revolution/min. But for the drilling job your screwdriver needs to have a rotation speed of 1000 revolution/min. You can also adjust the rotational speed of screwdriver using speed monitor.
3. Heads of driving tool
Normally when screwdriver performs as a drill, the drill chuck provided may be key or keyless. As we know, screwdrivers and drillers are two different tools, which requires a different amount of loads and speed to get operated. Hence the keyless drill chuck will be more suitable for screwdrivers.
4. Battery voltage
Ni-cad batteries are mostly used in light duty screwdrivers. These batteries hold the phenomena called “memory effect.” It means they can be charged when the battery gets fully discharged.
Without waiting for the complete discharge, Li-ion batteries can frequently be charged. For the small repair works, you can choose the screwdriver with a battery capacity of 1.2 A/h and battery voltage of 14 V.
5. Spindle lock
When the screw inserted tightened into the surface, it takes more efforts to take it out. Sometimes the screwdriver may slip away from the screw head because of the tightness. Spindle lock plays a vital part to fasten screw head with screwdriver to loosen the screw.
6. Handle
The handle can differ. The material should be smooth so that you can easily hold it during the drilling job, especially when your hands are damp, wet or sweating. Smoothness and shape of handle diminish your efforts and makes the job done easily.
How to Use Power Cordless Screwdrivers?
- Make sure you are using suitable bit: Confirm the type of screw is used on the surface and accordingly use the suitable bit. Make sure that your screwdriver bit should be well fitted on the screw head. If you are uncertain for the fitting of bit and bolt, then clench the bit at 45° angle. If the screw does not fall at this angle, then the bit is suitable for it.
- Check the fitting of a bit over screwdriver head: Keep checking the fitting of bit and screw. The bit must be seated well over the screw head. There are possibilities of slipping of improper bit out of the screw head. If you want to stop the slipping of screw and bit, then the use of magnetic holder is the effective way to avoid this trouble.
- Grip the sides of the screw by your hand: Smoothly hold the sides of the screw. This will avoid the slipping action of a screw or a bit during the operation. You should hold the sides of the screw until the screw starts inserting inside the wood or wall or any other material. Make a guide hole on it in case the material is thick.
