Tips: What are the pros and cons of a ratchet screwdriver?
1. Advantages of a ratchet screwdriver
The advantages of a ratchet screwdriver are to use the ratchet to improve work efficiency and reduce labor intensity. In addition to this advantage, the advantages of a ratchet screwdriver include:
- One-way ratchet design enables the screw to be twisted and tightened again without going back in the whole process. It is very easy and suitable for household use.
- The ratchet screwdriver has its own high-torque ratchet device, which is very useful for turning some screws with relatively long thread path. In other words, in the case of being stuck on one side, the screw can be tightened quickly by turning the wrist no more than 45 degrees, which is very convenient.
2. Disadvantages of a ratchet screwdriver
Although a ratchet screwdriver saves effort, it also has certain disadvantages. First of all, it is equipped with a ratchet device, which is heavier than ordinary screwdrivers and less convenient to carry. Second, the ratchet screwdriver has a corner, so it is not very convenient in the narrow space. However, the ratchet screwdriver set is usually equipped with the extension bar, which is helpful to operate at tight space.
