1. Impact Driver and Impact Wrench Basic Definitions
What is an Impact Driver?
An impact driver is defined as a power tool that is designed to drive screws and fasteners into various types of material effectively. Its design relies on rotational force and concussive blows to offer torque in a prescribed method. This makes it an irreplaceable instrument for specialists and citizens working on home projects. The structure of an impact driver means it is easily transportable, while its frictionless design and high speed make it suitable for a number of applications. However, the amount of torque that an impact driver can deliver is not very high, and this confines its operation to small screws and bolts. Nevertheless, it is still considered a best fit for woodworking, such as cabinetwork and other light application uses.
What is an Impact Wrench?
An impact wrench is used for high-impact torque jobs and is widely utilized in the automotive industry and other sectors. It applies rotational force and quick blows, making it an easy-to-use tool for loosening bolts and nuts. While an impact driver is small and lightweight, an impact wrench is comparatively larger and heavier due to its demanding tasks. However, the high torque of an impact wrench is impressive. Its size and higher price can be a con to users. However, it is suitable for use as a tool in the car wheel nut threading process, heavy machine requisites, and any construction job demanding high torque.
2. Key Differences Between Impact Driver and Impact Wrench
