Hammer Drill vs. Rotary Hammer — What's the Difference?
By Tayyaba Rehman — Published on January 11, 2024
A hammer drill is a power tool for drilling into hard materials, using a rapid hammering action. A rotary hammer, more powerful, uses a piston mechanism for a more forceful hammering action and can also include a chiseling function.

Key Differences
Hammer Drills are designed for drilling into concrete, brick, and other masonry, utilizing rapid back-and-forth hammering action to aid the drilling. Rotary Hammers, on the other hand, are equipped with a more robust mechanism, using a piston to generate a powerful hammering action, making them suitable for more demanding tasks.
The Hammer Drill is typically used for lighter, DIY tasks and can also function as a standard drill. It's less expensive and lighter than a Rotary Hammer. Rotary Hammers are geared more towards professional use, capable of handling larger holes and tougher materials.
In terms of power and efficiency, Rotary Hammers are more powerful and efficient at drilling into hard materials compared to Hammer Drills. This makes Rotary Hammers a preferred choice for heavy-duty applications.
Hammer Drills are more versatile and can be used for a variety of drilling tasks, not limited to masonry. In contrast, Rotary Hammers are specifically designed for drilling into concrete and other hard materials and often have a dedicated chisel mode.
Ease of use is another differentiating factor. Hammer Drills are easier to handle for non-professionals due to their lighter weight and simpler operation. Rotary Hammers require a bit more expertise and are generally heavier and larger.
