An impact driver is a power tool that uses a rotating motion to deliver high torque output. It is typically used for tasks such as driving screws and bolts, drilling holes, and removing stuck fasteners.
Choosing the right impact driver for your needs is important because it will determine the tool’s performance and suitability for different tasks. Impact drivers come in different voltage ratings, and two common ones are 18v and 20v.

18v Impact Drivers
18v impact drivers are powered by 18-volt batteries and are known for their medium power output. They are suitable for tasks such as driving screws and bolts, drilling holes in wood and metal, and removing stuck fasteners.
Pros of 18v impact drivers
-
- They are lighter and more portable than 20v impact drivers.
- They are generally more affordable than 20v impact drivers.
- They have a medium power output that is suitable for most tasks.
Cons of 18v impact drivers
-
- They may not have the power needed for heavy-duty tasks.
- They may not have the same battery life as 20v impact drivers.
20v Impact Drivers
20v impact drivers are powered by 20-volt batteries and are known for their high power output. They are suitable for tasks such as driving long screws and bolts, drilling holes in dense materials, and removing stubborn fasteners.
Pros of 20v impact drivers:
-
- They have a higher power output than 18v impact drivers, making them suitable for heavy-duty tasks.
- They have a longer battery life than 18v impact drivers.
- They may have additional features such as variable speed and torque control.
Cons of 20v impact drivers:
-
- They are generally more expensive than 18v impact drivers.
- They are heavier and less portable than 18v impact drivers.
Comparison of 18v vs 20v Impact Drivers
Performance comparison
In terms of performance, 20v impact drivers are generally more powerful than 18v impact drivers. However, 18v impact drivers may still be sufficient for most tasks and may be a better choice for those who do not need the extra power.
Battery life comparison
20v impact drivers typically have a longer battery life than 18v impact drivers. This is because they have larger batteries and can handle higher power demands. However, 18v impact drivers may still have a sufficient battery life for most tasks.
Price comparison
20v impact drivers are generally more expensive than 18v impact drivers. This is because they have more advanced features and a higher power output. However, prices can vary depending on the specific model and brand.
Tips For Choosing The Right Impact Driver For Your Needs
Here are some tips for choosing the right impact driver for your needs:
Determine your power need
Consider the tasks you will be using the impact driver for and whether you need a high or medium power output. If you will be using the impact driver for heavy-duty tasks such as driving long screws or drilling holes in dense materials, a 20v impact driver may be a better choice. If you will be using the impact driver for lighter tasks such as driving small screws or drilling holes in wood, an 18v impact driver may be sufficient.
Consider the battery life
If you will be using the impact driver for long periods of time or for tasks that require a lot of power, you may want to choose a model with a longer battery life. 20v impact drivers typically have a longer battery life than 18v impact drivers.
Consider the weight and size
If you will be using the impact driver for extended periods of time or in tight spaces, you may want to choose a model that is lightweight and compact. 18v impact drivers are generally lighter and more portable than 20v impact drivers.
Consider the price
Impact drivers can range in price from under $100 to over $200. Consider your budget and the specific features you need when deciding on a model.
Read reviews
Before making a purchase, read reviews from other users to get a sense of the impact driver’s performance and reliability.
Check the warranty
Make sure to check the warranty offered by the manufacturer before purchasing an impact driver. A longer warranty can provide added peace of mind and protection for your investment.
FAQs on “18v vs 20v Impact Driver”
What is the difference between an 18v and a 20v impact driver?
The main difference between an 18v and a 20v impact driver is the power output. 18v impact drivers have a medium power output and are suitable for tasks such as driving screws and bolts, drilling holes in wood and metal, and removing stuck fasteners. 20v impact drivers have a higher power output and are suitable for tasks such as driving long screws and bolts, drilling holes in dense materials, and removing stubborn fasteners.
Which is better, an 18v or a 20v impact driver?
It depends on your needs and budget. 18v impact drivers are generally more affordable and lighter, making them more portable and easier to use for extended periods of time. However, they may not have the power needed for heavy-duty tasks. 20v impact drivers are more powerful and have a longer battery life, but they are generally more expensive and heavier. If you do not need the extra power and do not mind a shorter battery life, an 18v impact driver may be the better choice. If you need the extra power and are willing to pay for it, a 20v impact driver may be the better choice.
Can an 18v impact driver handle heavy-duty tasks?
While 18v impact drivers are suitable for most tasks, they may not have the power needed for heavy-duty tasks such as driving long screws or drilling holes in dense materials. If you will be using the impact driver for heavy-duty tasks, a 20v impact driver may be a better choice.
Is an 18v impact driver sufficient for most tasks?
In most cases, an 18v impact driver will be sufficient for tasks such as driving screws and bolts, drilling holes in wood and metal, and removing stuck fasteners. However, if you will be using the impact driver for heavy-duty tasks or for extended periods of time, a 20v impact driver may be a better choice due to its higher power output and longer battery life.
Is it worth upgrading from an 18v to a 20v impact driver?
It depends on your needs and budget. If you are satisfied with the performance of your 18v impact driver and do not need the extra power or features of a 20v impact driver, it may not be worth upgrading. However, if you frequently use your impact driver for heavy-duty tasks or if you need the extra power and features offered by a 20v model, it may be worth considering an upgrade.
Final Note
18v and 20v impact drivers are both useful tools that can be used for a variety of tasks. 18v impact drivers are lighter, more portable, and generally more affordable, but may not have the power needed for heavy-duty tasks. 20v impact drivers are more powerful, have a longer battery life, and may have additional features, but are generally more expensive and heavier.
When choosing an impact driver, it is important to consider your needs and budget. If you do not need the extra power and do not mind a shorter battery life, an 18v impact driver may be the better choice. If you need the extra power and are willing to pay for it, a 20v impact driver may be the better choice.
