Drill vs Impact Driver: Which Tool Do You Need?

What is the Difference Between a Drill & a Driver?

Ever found yourself wandering down the power tools aisle, scratching your head over the difference between an impact drill and an impact driver? You're not alone! These two tools might seem similar at first glance, but they pack distinct punches when it comes to getting the job done.

Whether you're a seasoned DIYer or a newbie looking to level up your toolkit, understanding these powerhouse tools is key. Let's dive into the impact drill vs. impact driver debate to unravel their mysteries and discover which one suits your next project best.

What is an Impact Drill?

An impact drill, also known as a hammer drill, is your go-to tool for drilling into tough materials like concrete, brick, or masonry. Unlike regular drills that rely solely on rotational force, impact drills combine rotational force with a hammering action. This hammering motion helps to pulverise hard surfaces, making it easier to drill through without applying excessive pressure.

Impact drills are versatile, making them ideal for tasks requiring both drilling and light-duty masonry work. Below is our 710W corded impact drill from Nordic Power Tools.

What is an Impact Driver?

An impact driver, on the other hand, is designed primarily for driving screws and fasteners with high torque and efficiency. It operates similarly to a regular drill but with significant differences in mechanism and functionality.

Unlike drills that deliver constant rotational force, impact drivers deliver rotational force in bursts or impacts. This action is produced by internal mechanisms that generate a rotational hammering motion, resulting in greater torque output with less effort from the user.

Can You Use an Impact Wrench as an Impact Driver?

An impact wrench is primarily designed for high-torque applications like automotive repairs and heavy-duty fastening tasks. While it can drive screws, an impact wrench lacks the precision and versatility of an impact driver for woodworking or general construction.

Here's what an impact driver, also from our Nordic Power Tools range, looks like:

They don't look that much different from an impact drill - the real key to how they differ is in their operation and application.

How Do These Two Tools Differ?

The key difference between an impact drill and an impact driver lies in their intended purposes and the mechanisms they employ. Impact drills are versatile tools suitable for drilling holes in various materials and driving screws with moderate torque requirements. They provide smooth and consistent drilling and driving performance ideal for tasks where precision and control are crucial.

On the other hand, impact drivers excel in applications requiring high torque output, such as driving long screws, lag bolts, or fasteners into tough materials like hardwood or metal. Their unique hammering action allows them to deliver more force efficiently, making them invaluable for heavy-duty construction, carpentry, and automotive projects where speed and power are paramount.

But how do you know which one to use depending on what you need to do?

When to Use an Impact Drill

An impact drill is your go-to tool for a variety of tasks around the home or workshop. It's perfect for drilling holes in wood, plastic, drywall, and even light metals like aluminium. The smooth drilling action ensures clean and precise holes without damaging the surrounding material. Additionally, an impact drill is ideal for driving screws and fasteners into softer materials where a controlled and consistent driving force is needed.

Some examples of when to use an impact drill include:

Installing Cabinets: An impact drill is invaluable when installing kitchen cabinets or assembling furniture. It effortlessly drills pilot holes for screws, ensuring a secure fit without damaging the material.
Home Renovations: Whether it's hanging shelves, mounting curtain rods, or securing wall fixtures, an impact drill handles various tasks with ease, providing the necessary torque and control for precise installations.

When to Use an Impact Driver

An impact driver is designed for tasks that require high torque and efficiency. Here are some scenarios where an impact driver shines:

Driving Long Screws: Impact drivers excel at driving long screws into tough materials like hardwood or metal. The high torque generated by the impact mechanism allows for smooth and effortless driving without stripping the screw heads.
Decking and Construction: Constructing decks, fences, or framing requires driving numerous fasteners. An impact driver handles these tasks swiftly, reducing fatigue and increasing productivity.
Automotive Repairs: Impact drivers are indispensable in automotive work, such as removing lug nuts, bolts, or assembling components. The robust torque ensures fast and secure fastening without the risk of over-tightening.
Metal Fabrication: When working with metal, such as installing metal roofing or steel framing, an impact driver provides the power and control needed to drive screws quickly and effectively.

Do You Need Impact Driver Bits for an Impact Driver?

Yes, impact driver bits are specially designed to withstand the high torque and hammering action of impact drivers. Using standard drill bits can lead to premature wear or breakage.

Other Types of Drills and Drivers

Hammer Drill: A hammer drill is designed for drilling into hard materials like concrete, brick, or stone. It combines rotary drilling with a hammering action to break through tough surfaces.
Drill and Driver Combo: Combines the functionality of a drill and an impact driver in one tool. This versatility allows you to drill holes and drive screws using the same device.
Impact Wrench: While similar to an impact driver, an impact wrench is more powerful and designed primarily for loosening or tightening nuts and bolts in automotive and mechanical applications.

What Does Brushed and Brushless Mean?

When shopping for your new tool, you'll likely come across the phrase "brushed" and "brushless" - including within TopmaQ's own range of power tools! Essentially this refers to the tool's motor type:

Brushed Motor: Uses carbon brushes to conduct electrical current to the motor windings. These motors are generally less expensive but may require more maintenance and have a shorter lifespan.
Brushless Motor: Operates using electronic controllers instead of brushes. They are more efficient, generate less heat, and have a longer lifespan. Brushless motors are often found in high-end power tools.

As you can see, a brushless drill or driver is better than their brushed counterparts. That's why, at TopmaQ, we sell only brushless options.

Key Considerations When Buying Your Drill or Driver

While this guide should help you in choosing the right tool for your specific task or project needs, it's worthwhile also considering the following elements to ensure you get the most bang for your buck:

Frequency and Duration of Use: Determine how often and for how long you will use the impact driver to choose the appropriate model and battery type.
Battery Life: Consider the battery capacity (Ah) and how long it lasts on a single charge, especially for longer projects.
Power and Torque: Match the tool's power and torque ratings to the tasks you intend to perform. Higher torque is needed for tougher materials and larger fasteners.
Weight: A lighter tool is easier to handle for extended periods, reducing user fatigue, especially in overhead or vertical applications.
Motor Type: Decide between brushed and brushless motors based on performance requirements, durability, and budget.
Accessories: Ensure you have the right accessories such as impact-rated bits and sockets designed to withstand the high torque of impact drivers.
