When comparing a hammer drill vs an impact driver, it helps to understand how they work so you can better understand what jobs they're intended for. While they both look nearly identical to a standard drill, they serve completely different purposes. Some users may prefer one tool, while others benefit from owning both a hammer drill and an impact driver in their toolbox.

 

Here, we've explained the difference between a hammer drill and an impact driver so you can decide which is right for your project.

 

What is a Hammer Drill?

 

A hammer drill operates similarly to a standard drill but supplements the rotation with a hammering motion directed at the back of the bit. This allows a hammer drill to drill into hard materials like brick, cinderblock, and solid concrete by subtly chipping away at the material as the bit rotates.

 

What Is an Impact Driver?

 

An impact driver is a drill-like tool that adds impact to rotational force depending on the immediate torque requirements of the task at hand, allowing it to drive large fasteners easily.

 

Hammer Drill vs. Impact Driver: What Are They Used for?

Both hammer drills and impact drivers can serve multiple purposes, but they do shine inspecific uses.

 

Hammer drill uses

If you’ve tried to drill a hole in brick, tile or concrete, you know how difficult the job can be. These are situations where a hammer drill can be indispensable. With the hammer function activated, the drill punches the tip of the bit forward into the material, making short work of an otherwise monotonous task.

 

Some common uses for hammer drills include:

 

Starting and drilling a hole on a slippery tile or glass backsplash.

Drilling through basement concrete to attach framing lumber.

Drilling into concrete steps for attaching handrails.

Hanging TV wall mounts, shelves or pictures on brick walls.

Drilling holes in a garage floor for permanently fixing power tool stands to the ground.

Drilling holes for attaching mechanical system brackets to a concrete utility room floor.

Note: Drilling through masonry surfaces with a hammer drill requires special masonry bits.

Includes a lock-on button to maintain speed during prolonged use. With a large trigger switch for comfortable use and a rubberized ergonomic soft grip, this hammer drill offers superior comfort and control, making it ideal for extended tasks.

 

Impact driver uses

 

Impact drivers are all about packing as much punch as possible into a small tool. They’re helpful for driving smaller fasteners at high speeds, as well as driving longer fasteners without breaking out wrenches or sockets.

 

Common uses for impact drivers include:

 

Driving smaller screws into dense or thick wood. (They would split thin wood.)

Driving longer, heavy-duty screws quickly, like when hanging cabinets or other heavy objects.

Fastening a deck ledger board with lag bolts.

Driving screws in tight spots, like between joists or studs, or inside cabinets.
