When Not to Use an Impact Driver? Discover now!

 An Impact driver is a handy tool in building or renovating things. However, it is not an item that can do well in all cases. There will be times when it cannot work properly. So what are those cases? Join us to find out the correct answer in the article below!

When not to use an impact driver?

You cannot use the impact driver in the following situations:

  • Perform work that requires precision
  • Working with soft or too hard materials
  • Working with short screws
  • Drill a hole
  • Shank Bits Not Hex

Rarely does a tool can do well in all cases with different conditions. Impact driver too! It will not be usable in some cases with some materials.

When Not to Use an Impact Driver?

To know more about the cases where the impact driver cannot use. Stay tuned for more of our shares below!

Perform work that requires precision

Impact drivers have very strong impact, they also continuously generate very fast torques. It is beneficial for speed of use but also for damage. The fast twists and strong collisions make it very difficult for the user to control.

Impact driver is not effective in high accuracy cases

It is almost impossible to use them for purposes that require high accuracy. The strong force causes the impact driver to continuously vibrate. You can deflect the target at any time.

Also, the impact driver only has a few speed and torque settings. So they have less choice in cases. Therefore, in many cases, users cannot install and use it correctly.

With thin materials or small holes, using an impact driver is impossible.

Working with soft or too hard materials

Impact drivers have very strong generating forces. So they are not suitable for soft materials. Especially softwood. They will work inefficiently because their force is not needed.

You can imagine that you are holding a very large bone-slicing knife to peel fruit. Surely the results will not be as good as you use a fruit knife to do. Using the impact driver is similar.

The impact force of the impact driver is very strong. They are suitable for hardwoods or building bricks. In case of use with soft materials, they will not work correctly. Worse, it can damage your softwood piece.

With softwood you can use a fretboard or a normal driver.

In contrast, with too hard materials such as concrete or solid metal blocks, the impact driver cannot work well. This is because they are not powerful enough to act on such a material. In this case you can use a hammer drill instead.

Working with short screws

Impact drivers are suitable tools for inserting even very long screws or bolts. It is the large amount of torque and the strong impact that makes it easier for long screws to enter the material. However, it does not work with short screws.

Impact drivers can't work well with short screws

Screws that are too short will not be able to withstand the high impact force and torque of the torque. Too fast a screw speed can break the screws or strip them. So with any material. Impact drivers can’t work well with short screws.

Impact driver can’t drill holes

Currently some impact drivers can drill holes. But this is not the good job it can do. Because manufacturers make impact drivers not for drilling holes.

Because of their strong impact force and fast torque, impact drivers often drill too deep for what you need. Accuracy is also not perfect because the impact driver is difficult to control. Another problem is that the bits of this tool are mostly hexagons. They are not suitable for drilling holes.

If you want to drill holes, especially in wood, consider using a regular drill.

Some impact drivers can drill holes but this is not the good job it can do

Shank bits not hex

A rather limited thing about the impact driver is its bits, they limit to hex bits. This special mechanism makes it impossible for the impact driver to use other shaped bit types.

Although hex-shaped bits are very popular today, not all bits are hex-shaped. This is the limitation of the impact driver. In many cases it is necessary to use non-hex bit types. It cannot work.

If you are doing work that requires constant bit shape changes, the impact driver is not a good choice for you. Instead, you might consider using some sort of normal drill. They are capable of working with more bit types.


The impact driver is a tool that brings many benefits to you in projects. However, it is not always the best tool. When should you not use the impact driver? We have given you the most accurate answer. Hopefully, our sharing will be useful for you!
