At the same time, professional contractors say that an impact driver can cut fastening time by up to 40% compared to a standard drill.

Still, many DIYers wonder—if they look the same, what’s the real difference between a drill and an impact driver?

In this guide, we’ll break down what each tool does, how they work, their pros and cons, and most importantly, when you should reach for one over the other.

By the end, you’ll know exactly which tool to use for drilling holes, driving screws, or tackling heavy-duty fastening jobs.

What Is a Drill? (Definition & Basics)

A drill is one of the most widely used power tools for both professionals and DIYers. Its primary purpose is to drill holes in various materials like wood, plastic, and metal.

At the front of a drill is a chuck, which securely holds different types of drill bits. Most modern drills feature a keyless chuck, allowing quick bit changes without special tools.

Drills often include adjustable clutch settings to control torque. This prevents overdriving screws and helps protect delicate materials during use.

The variable speed trigger gives users control over how fast the bit spins. Light pressure provides slow speed for precision, while full pressure delivers maximum drilling speed.

Drills come in both corded and cordless models. Cordless drills, powered by lithium-ion batteries, are more popular due to their portability and convenience.

Some drills are compact and lightweight, designed for small jobs and tight spaces. Others are heavy-duty models built for construction and demanding projects.

In short, a drill is a versatile tool that handles a wide range of tasks. From drilling pilot holes to light screwdriving, it’s often the first power tool people buy.

What Is an Impact Driver? (Definition & Basics)

An impact driver is a power tool designed primarily for driving screws and bolts with high torque. It looks similar to a drill but functions very differently.

Instead of a chuck, it uses a ¼-inch hex collet. This collet only accepts hex-shank bits that are strong enough to handle high torque.

The tool uses a hammer-and-anvil mechanism inside. This system delivers short, powerful bursts of torque while still rotating the bit.

These bursts, known as impacts per minute (IPM), provide extra force without requiring much effort from the user. This makes it easier to drive long screws into dense materials like hardwood.

Most impact drivers are cordless and powered by lithium-ion batteries. They are lightweight, compact, and easy to maneuver in tight spaces.

Brushless impact drivers are especially popular among professionals. They run cooler, last longer, and provide more efficient power compared to brushed models.

Unlike drills, impact drivers don’t use adjustable clutches. Instead, they automatically regulate torque, reducing the chance of stripping screws.

In short, an impact driver is a specialist tool built for fastening power. It’s perfect for construction, woodworking, and projects that involve heavy-duty screws and bolts.

Drill vs Impact Driver – Key Differences

The main difference between a drill and an impact driver is how they deliver torque. A drill provides steady, continuous rotation, while an impact driver adds concussive bursts of torque for extra power.

A drill uses a chuck that can hold a variety of round and hex-shank bits. An impact driver uses a ¼-inch hex collet that only accepts hex-shank bits designed for high torque.

When it comes to control, drills feature an adjustable clutch with multiple torque settings. This makes them better for precision work and delicate tasks.

Impact drivers do not have a clutch. Instead, they automatically adjust torque through the hammer-and-anvil mechanism, reducing the chance of stripped screws.

In terms of power, impact drivers produce much higher torque in a compact size. Drills are less powerful but more versatile since they can both drill holes and drive screws.

Noise is another difference. Impact drivers are louder due to their concussive action, while drills operate more quietly.

For user comfort, impact drivers absorb much of the resistance, reducing wrist strain during long fastening jobs. Drills can require more physical effort, especially on tougher materials.

In short, a drill is the all-purpose tool for drilling and light fastening. An impact driver is a specialist tool built for power and heavy fastening.
