When Not to Use an Impact Driver?

It goes without saying that we all are known to the traditional drivers used to fix a nut on wood or metal. But you’re not here to know about them. Of course, we’ve decorated our guide in terms of a power tool called an impact driver. If you find any surface that is jammed for heavy rust or over-torqued, then an impact driver is nothing but a beast in this place.

Besides, it provides high torque to lose or drive-in screws. The effects of the impact driver can easily beat the traditional drilling system. But you should know about the tool before you are going to drill it into the object. We are going to provide you a guide that will make it clear when to use an impact driver and when not to use it.

What is an Impact Driver Used for

It’s mandatory to define an impact driver used to loosen the screws from a rusted surface. Besides, you may also find some metal surfaces that are jammed for rust. Impact driver bits are apt for those rough surfaces.

Precisely, the drivers aren’t like the traditional 3-jaw chuck and come with a hexagonal-shaped. A magnet is used on this stuff for making the connection with the screw.

When to Use Impact Driver

It’s undeniable that an impact driver covers a vast area of usage. You may call it a necessary tool for the present time, but there’re some facts that you should understand. Sometimes, a drill driver or traditional drilling method is enough to complete your operation. But there are some cases where the impact driver is a must for you.

  • Drilling the self-threading screws.
  • Losing over-torqued screws.
  • Drilling into hard surfaces.
  • Drilling on metal surfaces that are jammed for rust.

How Does an Impact Driver Work

If you’re working with it, you should know how an impact driver works? The primary stage of working is combining rotational motion. This rational motion creates high torque. The hammering process of the impact driver helps your screw to go faster.

A strong motor is installed on it. But you know, there comes a unique spring-loaded hammering mechanism that paves the way to lift up and rotates. And then the spring pushes it down to create a rational and high torque.

Different Principles of Impact Driver: Impact Driver vs. Hammer Drill

You all are getting confused after seeing the working procedures. However, you’ll find some key differences between an impact driver & a hammer drill.

So, an impact driver provides screw 50 times a second. It can work 5 times faster than other drill drivers and hammer drills. There is no choice for the impact driver to change the torque. Besides, the driver lets you use only a ¼” hex-shank drill. So, they are ideal for driving the screw, and professionals prefer to use them in their workplaces.

On the contrary, if you need to drill holes into rock, brick, and concrete, a hammer drill suits you the most. Besides, it offers you a setting option that can turn off the hammer function. And other drivers and drills are lighter than these hammer drills. Precisely, you can change the driver bits for accurate torque.

For more details, you may find some articles like “Impact driver vs. Hammer drill.” So don’t be confused.

Advantages of Impact driver:

After reading this guide, you may find some disadvantages of impact drivers. But the advantages will indicate the scope of using an impact driver. You will be clear about the question “when you need to use an impact driver.”

Higher Torque

It’s one of the most important features capable of blowing around 50 times to loosen the screw. Impact drivers are five times powerful than other drill drivers. For the fastest operations, this driver is an ideal option.

Impact Driver Bits

Impact driver bits are strong enough for drilling operations. You may get the fastest and deepest torque operation from the ¼” hex-shank drills and driver bits.

Less Recoil

It has better recoil control than other types of drills. Less recoil will give you the best control over the impact driver.

Easy to use 

You can easily hold it for a long time, and it is lighter than hammer drills. Besides, it comes with a shorter head than the average cordless drill, and it’ll enhance the better grip. You can use it in small spaces comfortably.

Disadvantages of Impact Driver:

  • You need to spend more bucks than other drills.
  • It cannot hold different types of drill bits. For this, the accuracy level is less than the other drills.
  • This has a lack of torque power.
  • The magnetic system for holding a screw is weaker than the other types of drills.

How to Choose the Best Impact Driver

Now you are clear about the advantages and disadvantages of an impact driver. Here’re some professional tips and tricks that will make a clear way to pick the right one.

  1. The voltage and torque capacity is the first thing that you need to judge.
  2. The speed of the impact driver is the most important. So go for an impact driver that has a high RPM count.
  3. Then judge the battery life of this kit.
  4. The main driving source of an impact driver is the motor.


What is the torque range of an impact driver?

The torque usually ranges between 100Nm to 200Nm (1800 lbs.)

What is the average speed range of an impact driver?

By calculating from some best brands, we have got 2500 rpm on average.


Actually, the name implies the truth of its functions, and you don’t miss the chance to revamp your stock with this highly powerful tool. Hopefully, you are aware of the applications.

We have motioned about the difference between the hammer drill and impact driver, the working procedure, and the impact driver’s pros and cons. So you can easily judge when to use it and when not.
