10 Differences Between a drill and impact driver

The Difference Between a Drill and Impact Driver

What is a Drill?

A drill is a versatile power tool that is used to bore holes or drive screws into various materials such as wood, metal, or plastic. It consists of a rotating chuck that holds drill bits or driver bits, and a handle or trigger that activates the tool.

Examples of a Drill

  • Hand Drill
  • Hammer Drill
  • Cordless Drill
  • Drill Press

Uses of a Drill

Drills have a wide range of applications, including:

  • Drilling holes for various purposes (e.g., plumbing, electrical, woodworking)
  • Driving screws or other fasteners
  • Mixing paint or other substances with an appropriate attachment

What is an Impact Driver?

An impact driver is a power tool that combines rotational force with concussive blows to increase torque. It is primarily used for driving screws, nuts, and bolts into tough materials. Instead of a chuck, it features a collet that holds hexagonal driver bits securely.

Examples of Impact Drivers

  • Cordless Impact Driver
  • Brushless Impact Driver
  • Right Angle Impact Driver

Uses of Impact Drivers

Impact drivers are commonly used in the following scenarios:

  • Driving large or long fasteners (e.g., lag bolts)
  • Fastening in hard materials like concrete or metal
  • Assembling or disassembling heavy-duty machinery

Differences Table

Difference Area Drill Impact Driver
Chuck/Collet Type Drill chucks are typically keyless or require a key to tighten the drill bits Impact drivers use a collet that only accepts hexagonal driver bits
Rotational Force Drills provide continuous rotational force Impact drivers combine rotational force with concussive blows
Fastening Power Drills are generally less powerful than impact drivers for fastening applications Impact drivers deliver higher torque and have superior fastening power
Control Drills offer more control over speed and allow for variable speed settings Impact drivers have less control over speed but provide better control for driving fasteners
Applications Drills are suitable for a wide range of applications, including drilling and driving screws Impact drivers excel in heavy-duty fastening applications and can handle tough materials
Noise and Vibration Drills produce more noise and vibration compared to impact drivers Impact drivers generate less noise and vibration due to their hammering action
Size and Weight Drills are generally larger and heavier in size Impact drivers are more compact and lightweight
Price Drills are generally more affordable, especially for entry-level models Impact drivers are typically more expensive due to their higher torque capabilities
Bit Change Drills require different drill bits or driver bits for various applications Impact drivers use a quick-change hexagonal collet for easy bit swapping
Driving Speed Drills offer adjustable driving speed settings Impact drivers have a fixed driving speed


In summary, while drills and impact drivers are both valuable power tools, they have distinct differences in terms of chuck/collet type, rotational force, fastening power, control, applications, noise and vibration, size and weight, price, bit change mechanism, and driving speed. Choosing between the two depends on the specific tasks you frequently need to perform.

People Also Ask

  1. Can I use a drill as an impact driver?
  2. No, drills and impact drivers have different mechanisms and functions. It is not recommended to use a drill as an impact driver or vice versa.

  3. Which tool is better for driving screws?
  4. An impact driver is generally better for driving screws, especially in hard materials or when dealing with larger or longer fasteners.

  5. Do I need both a drill and an impact driver?
  6. While not necessary, having both a drill and an impact driver can increase your efficiency and versatility when working on various projects. However, if you have to choose only one, consider your specific needs and the types of tasks you commonly perform.

  7. Are drills and impact drivers interchangeable?
  8. No, drills and impact drivers are not interchangeable due to their different functionality and mechanisms. It is important to use the appropriate tool for each task.

  9. Can I use an impact driver for drilling?
  10. Impact drivers are not designed for drilling. While they may have a chuck that can accommodate drill bits, their rotational force and hammering action are more suitable for driving applications rather than creating precise holes.
