Screwdriver Set Bits

Tips: Functional classification of screwdrivers

1. Ordinary screwdriver
This kind of screwdriver is a simple hand tool with the head and handle together, which is easy to use as long as it is taken out. However, as there are many different lengths and thickenings of screws, it is sometimes necessary to prepare many different sizes of screwdrivers.

2. Combined screwdriver
A combined screwdriver refers that the screwdriver shaft and handle is separated and the screwdriver bits can be replaced to screw and unscrew different types of screws, instead of carrying a lot of screwdrivers. The advantage is to save space, but easy to lose the screwdriver bits.

3. Electric screwdriver
Electric screwdriver, as the name suggests, uses electric motor instead of manual installation and removal of screws, usually combined with many screwdriver bits.

4. Watch screwdriver
It belongs to the precision screwdriver, and it is commonly used in the repair of hand strap watches, so there is a name.

5. Mini diamond screwdriver
The head handle and body length size are smaller than those commonly used screwdrivers, not belonging to watch screwdrivers.
