What is the difference between an electric wrench and a hand drill?

Electric wrenches and hand drills are two different power tools, each with unique functions and application scenarios. Here are the main differences between them:

 ‌1 Functions and Applications‌:

‌Hand electric drill‌ is mainly used for drilling and is suitable for tasks such as home decoration, metal and wood drilling, and screw tightening. The torque and speed of the electric hand drill are designed for drilling and screw tightening, and are suitable for lightweight work.

‌Electric wrenches‌ are mainly used for tightening and loosening bolts and nuts, especially in applications that require high torque, such as construction, car maintenance, etc. The biggest feature of the electric wrench is its high torque output, which is suitable for operations requiring large torque.

 ‌2 Structure and Design‌:

Electric hand drills typically have higher rotational speeds, are designed to rotate the drill bit for drilling, and are constructed to be more suited to the rotating action. The rotation speed of electric hand drills is generally around 2000rpm and the torque is moderate, which can meet most household and light industrial uses.

Electric wrenches work by impact and swing, similar to the meshing rotation of two cross-scale gears, producing high torque. This design makes the electric wrench perform well in applications requiring high torque, such as bolt tightening on steel bridges, factory buildings, etc.

3 Usage scenarios‌:Hand drills are suitable for scenes that require drilling and screwing, such as home decoration, furniture making, drilling of metal and wood, etc.

Electric wrenches are more suitable for applications requiring high torque, such as automotive repair, scaffolding construction, railway bridge construction and other engineering fields.

 4 Price and Cost‌:

Hand drills have a wide price range, ranging from a few hundred dollars to thousands of dollars, depending on the brand, features and performance.

Electric wrenches also vary in price based on brand, features and torque size, but are generally more expensive than hand drills because their high torque requirements result in higher manufacturing costs.

To sum up, choosing between an electric wrench or a hand drill depends on the specific application needs. If the main work is drilling and light screw tightening, a hand drill is a better choice; and if operations that require high torque, such as bolt tightening, an electric wrench is more suitable.
