Hammer Drills vs. Impact Drills: What's the Difference?

Edited by Huma Saeed || By Sumera Saeed || Updated on October 25, 2023
Hammer drills provide rapid hammering action for drilling in masonry; impact drills exert rotational force for driving screws.

Key Differences

Hammer drills are designed to combine rotational drilling with a rapid back-and-forth hammering motion. This hammering action helps break up masonry materials like brick or concrete, making it easier for the drill bit to bore through. Impact drills, on the other hand, focus on delivering high torque in rotational bursts, making them ideal for tasks like driving screws or fastening bolts.

Hammer drills excel when drilling into hard, brittle materials where the hammering function can assist the drill bit's progression. This tool is particularly valuable for construction professionals and DIY enthusiasts working on masonry projects. Conversely, impact drills offer sudden rotational impacts, ensuring screws are driven deep without stripping their heads or causing user fatigue.
