Impact Driver vs Impact Wrench: What's the Difference?

Impact drivers and impact wrenches are two common types of power tools. They are used extensively by mechanics, many of whom rely on these tools to secure fasteners. While impact drivers and impact wrenches are used for similar purposes, though, they aren't the same. They are two different types of power tools with their own unique characteristics.

What Is an Impact Driver?

An impact driver is a power tool that's designed for driving screws and other fasteners into objects. It uses a rotary and concussive force to deliver high torque output Whether you're assembling furniture, building a patio or working on your car, you may want to use an impact driver.

What Is an Impact Wrench?

An impact wrench is a power tool that's designed for loosening and removing fasteners. Hand-loosening isn't always enough. You can twist a nut or bolt using all of your strength without it actually loosening. In cases such as this, you may want to use an impact wrench. Impact wrenches can quickly and easily loosen otherwise stiff fasteners.

Differences Between Impact Drivers and Impact Wrenches

Based on their appearance, you may assume impact drivers and impact wrenches are the same. They are two common types of power tools that look strikingly similar. But appearances can be deceiving. There are several key differences between impact drivers and impact wrenches.

As previously mentioned, impact drivers and impact wrenches are used for different purposes. Impact drivers are used for driving fasteners into objects, whereas impact wrenches are used for loosening and removing fasteners from objects.

Impact drivers and impact wrenches use different power sources. Most impact drivers are electric. Some of them are corded, whereas others are battery powered. Regardless, most impact drivers on the market are electric. Impact wrenches, in comparison, are available in electric and pneumatic models. They use compressed air to loosen and remove fasteners from objects.

While they are both powerful, impact drivers are typically stronger than impact drivers. They can produce more torque. Torque, of course, is a measurement of turning force. With more torque, impact drivers can produce a stronger turning force.

You may notice that impact wrenches are heavier than impact drivers. They both feature a similar size, but most impact wrenches are heavier than their driver counterparts.

While prices vary, impact wrenches typically cost more than impact drivers as well. They are more complex tools, and with a higher production cost, the have a higher price tag.
