Electric screwdrivers are basically power torque screwdriver. Torque screwdriver has some mechanism for ensure tightening up to a specified torque avoiding excessive torque. All manual and electric screwdriver have a torque limiting clutch system that disengages after the preset torque has been reached. Electric screwdriver can be standalone as battery powered tool or powered with electric cord. As normally for DIY works we use standard power drill like we talked in the guide to buy power tools to drill, some of them like our recommended hand drill Bosch GSB 450 works as powerful electric screwdriver too.
If you are a professional who need dedicated varying power electric screwdriver, then you should look around models like DEWALT DCF680N2 gyroscopic screwdriver, DEWALT DW920K-2 like models which costs over $150. As it is a generalised guide, we will point the readers towards the screwdrivers which do not screw the owner.
Electric Screwdriver Buying Guide For DIY and Home Usage
We recommend to use drill like Bosch GSB 450 which officially double ups as electric screwdriver and has some screwdriver bits. However, they are funny and overpowered for a PCB or electronic thing. Bosch GSB 450 with screwdriver bits is your one set. It is tricky to use Bosch GSB 450 as screwdriver. The power switch actually vary the rotational speed depending on the pressure given on the power switch. The basic trick to buy another less powerful yet a machine which can not screw the owner is to select the electric screwdrivers which has :
- Both electric mode and manual mode
- Handle is angulated but can be folded to make straight
- Supports standard battery
- Supports standard screwdriver bits
- Costs lesser
- A practical size
The above points are for obvious reason – if the motor of electric screwdriver blows away then basically it will work as manual torque screwdriver. The thing which satisfies our monarchial criterion is known as dual angle electric screwdriver with manual mode or dual angle electric screwdriver with spindle lock.
What to Look While Buying an Electric Screwdriver
We should look while buying electric screwdrivers are just few points :
- Speed : Some electric screwdrivers have variable speeds. All drivers have a reverse function
- Spindle lock : This function allows you to lock the head if you want to use it as a manual screwdriver.
- Handle : Soft grip and rubber handles can be more comfortable.
- Torque Control : This can increase the control while screwing into different materials or different size of screws.
There are various manufacturers who has dual angle electric screwdrivers with manual mode. Black & Decker A7073 satisfies our all criterion with Amazon’s rebate price around $10 at any country. or Black & Decker AS600P model is near same but cost is $20, because Black & Decker AS600P has Spirit Level, Measuring tape and Torch Light too. We think Black & Decker A7073 is better choice.
