How Does An Impact Drill Work ?

At first glance, impact drills may look like standard drills, but they operate with a clever twist. 

Both tools drive screws using rotational force—but the real magic begins when resistance is met.

Here’s how it works: when the motor senses resistance, a spring engages, storing energy. 

This energy releases in a powerful burst, similar to a surge of electricity. That force drives the hammer forward, striking the anvil in rapid succession.

This hammer-anvil mechanism transforms the impact drill into a torque powerhouse. 

The result? A major boost in rotational force that makes driving screws through tough materials like hardwood or metal surprisingly easy.

In short, an impact drill combines constant rotation with rapid, pulsating blows—thanks to the coordinated action of its hammer, anvil, and spring. 

This makes it the ideal tool for heavy-duty drilling and driving tasks.
