Understanding the basics of impact drivers and drills
How drills and impact drivers work
When looking at cordless drills and impact drivers, it’s important to understand how these power tools operate. Both are designed for drilling and driving tasks, but they use different mechanisms to deliver force and rotational power. A standard drill uses a steady rotational force to turn drill bits or driver bits, making it ideal for drilling holes in wood, metal, or plastic, and for driving small screws into softer materials.
Impact drivers, on the other hand, combine rotational force with quick, repeated bursts of impact. This force impact helps drive screws and fasteners into tougher materials or when working with large fasteners. The impact mechanism delivers higher torque than most standard drills, making it easier to drive long screws or bolts without stripping the bit or fastener.
Key differences in design and function
- Drills: Versatile for drilling holes and driving screws. They use adjustable speed and clutch settings to control torque, making them suitable for a wide range of drilling and driving tasks.
- Impact drivers: Specialized for driving screws and fasteners impact. They deliver higher torque through a hammering action, which is especially useful for tough materials or large fasteners.
While both tools can handle basic drilling and driving, the choice between a drill and an impact driver often comes down to the type of work you plan to do and the materials you’ll be working with.

Key features to compare in impact driver vs drill
Comparing Power and Performance
When looking at drills and impact drivers, the first thing to notice is how they deliver power. Drills use steady rotational force, which makes them ideal for drilling holes and driving small screws. Impact drivers, on the other hand, combine rotational force with quick bursts of impact. This extra force impact helps drive large fasteners and stubborn screws with less effort from the user.
Torque and Speed Differences
Torque is a key factor in choosing between these tools. Impact drivers offer much higher torque than standard drills, making them suitable for heavy-duty driving tasks. Drills typically have adjustable speed settings, giving more control for delicate jobs like drilling small holes or working with soft materials. Impact drivers usually have fewer speed options but excel in delivering high power for tough fasteners.
Bit Compatibility and Versatility
Both tools use different types of bits. Drills are compatible with a wide range of drill bits and driver bits, making them versatile for drilling and driving screws. Impact drivers require hex-shank bits designed to handle the force impact generated during use. If you plan on switching between drilling and driving tasks often, a drill driver combo or a cordless drill set with multiple bits can be a practical choice.

When to use an impact driver instead of a drill
Why impact drivers excel at tough driving tasks
When you’re faced with demanding driving tasks, such as securing large fasteners or driving long screws into dense materials, impact drivers often outperform traditional drills. The main reason is the unique mechanism inside impact drivers, which delivers rapid bursts of rotational force (torque) combined with concussive blows. This force impact helps the tool drive screws and fasteners with less effort from the user, reducing wrist strain and minimizing the risk of stripping screw heads.
- Higher torque: Impact drivers generate significantly more torque than standard drills, making them ideal for driving large fasteners and lag bolts.
- Efficient driving: The combination of rotational force and impact action allows for faster and more consistent driving, especially in tough materials like hardwood or metal.
- Less cam-out: The impact mechanism reduces the likelihood of the driver bit slipping out of the screw head, which is common with high-torque driving using regular drills.
Best scenarios for using an impact driver
Impact drivers shine in situations where you need to drive a lot of screws quickly, or when working with larger fasteners that require more power. For example, assembling decks, building fences, or installing subfloors are tasks where the extra force and speed of an impact driver make a noticeable difference. If you often work with long screws or bolts, or need to drive fasteners into tough materials, an impact driver is a valuable addition to your tool kit.
While impact drivers are excellent for driving screws and bolts, they are not designed for drilling holes with standard drill bits. For drilling holes, especially precise or large-diameter ones, a drill or drill driver is still the preferred tool. However, some impact drivers can handle special hex-shank drill bits for light drilling tasks, but their main strength remains in driving fasteners impact tasks.
