When Not to Use an Impact Driver The Ultimate Guideline

Impact drives are among the most useful innovations of the 20th century,

yet they have their drawbacks.

A standard drill/driver is the best tool in some instances, but in others,

such as when doing more refined work, a portable screwdriver is preferable. here we discuss when not to use an impact driver

Drive screws with ease and little effort using an impact driver’s intense rotating bursts, which make quick work of even the toughest, thickest materials. Without the ability to adjust the speed, impact drivers generate a lot of torque, making them inappropriate for jobs requiring more finesse.

I’ll describe some of the most frequent circumstances in which using an impact driver is a bad idea, along with better options for doing the same tasks.

Impact Driver Vs Drill

The main difference between impact drivers and standard cordless drills is the amount of torque they generate. The rotational torque of a standard drill is far smaller than that of an impact driver, although the two tools serve similar purposes.

However, an impact drill is not the same as a hammer drill. A hammer drill’s stroke comes from behind the tool. If you want to drill or drive an impact driver through anything tough, like concrete, this is how to do it.

A hammer drill works by pounding the drill’s back with a hammer to break through the surface. A similar performance can be attained using an impact driver but at around 50 release and returns per second rates. As a result, the drilling process is smoother than with a hammer drill.

Nevertheless, you should use appropriate hearing protection while using an impact driver. The clutch on an impact driver sets it apart from a regular drill. Because of the impact driver’s no-clutch design may be used in places where a standard drill would jam.

There are restrictions on the drill bits that may be used in a clutch-less impact drill. It is important to consider the needs of the project at hand while deciding the tool to use.

While compared to an impact driver, the conventional drill is more exact and has a more refined touch while drilling. However, if you need to drill through rock or other hard material, an impact driver offers the torque you need to get the job done.

What is Impact Driver  

The standard impact driver resembles a drill in appearance but is more portable and shorter.. Like a drill, it has a handle, trigger, and a chuck style known as a hex collet.

An impact driver’s spring-loaded concussive force mechanism sets it apart from a drill, allowing it to provide the consecutive bursts of power that users want with drills more efficiently. Moreover, These bursts are instantaneously provided with no user intervention.

When it detects resistance in the work material, an impact driver switches to its bursting action and continues drilling at a steady speed.

Air compressor-driven impact drivers have been standard in the auto shop for quite some time. However, impact drivers are relatively new equipment for home renovation, and they are small, cordless, and lightweight.

The primary function of an impact driver is not to bore holes but to drive fasteners with a great deal of torque. An impact driver’s primary function isn’t drilling holes, but it is one of its many uses.

Functions of an Impact Drive


The term “handle” or “grip” refers to the part of the impact driver that you’ll be grasping. Grasp anything safely with the help of this device. So it’s usually built of some kind of rubbery or plastic material, and it has a bunch of little divots or depressions in it.


Pressing the trigger of an impact driver activates the motor, allowing the user to rotate the bit. A variable-speed trigger is standard on many modern impact drivers. The variable speed trigger also allows the user to start out at low speeds and build up to higher ones as desired.


A collet, ring, or sleeve that slips over the bit secures it in place. All impact drivers require 14″ hex bits.


A bit is a metal tip that may be used with an impact driver and is held in place by the tool’s collet. In a variety of shapes and sizes, they serve a variety of functions.When working with an impact driver, ensure you only utilize bits designed to withstand the force of an impact.

Switch for forwarding and Reverse Directions

To change the direction of the bit, use the forward/reverse switch. When driving screws clockwise, use a bit that rotates in the opposite way. If you turn the bit counterclockwise, you may unscrew the object.


Thanks to the battery, the impact driver can use without plugging into an outlet. This is helpful if you need to work somewhere without easy access to an electrical socket.

Light-Emitting Diode

These days, it’s not uncommon to see impact drivers outfitted with LED lights, which come in handy in dim conditions or while operating in tight quarters.

How Does an Impact Driver Perform?

You should be familiar with the operation of an impact driver if you plan to use one. The first step in completing a task is to coordinate everyone’s actions so that they form a unified whole.A lot increases torque because of this logical action.

Also, because of the impact driver’s pounding action, your screw will tighten much more quickly. It features a robust motor. However, a unique spring-loaded hammering mechanism allows for lift and rotation. As a result, the torque is both reasonable and high since the spring pulls it down.

Usage of an Impact Driver

Undoubtedly, an impact driver has a wide variety of applications. Although you may consider it an essential tool at the moment, there are a few things you should know. Firstly, a drill driver or the traditional method of drilling may be all that’s necessary to get the best result. You can get by without an impact driver in most circumstances, but there will be times when you need one.

  • Threading the self-tapping screws into the drill.
  • Inadequate tightening causes screws to fall out.
  • Making holes in solid objects.
  • Drilling is possible even in soot metal.

When Not to Use an Impact Driver

It should come as no surprise that impact drivers play an important role in the construction sector. Impact drives serve a unique purpose by combining a hammer and an anvil to generate disproportionately high levels of force and torque. Concrete screw anchors, metal studs, and dense wood are some of the many materials that might benefit from using an impact driver.

The use of an impact driver isn’t the only option, though. In addition to standard drills and drivers, hammer drills are also available. While impact drivers serve many purposes, specific tasks are beyond their capabilities. In addition, various scenarios exist where an impact driver is not the optimal tool.

Flanged Shank Bits

While impact drivers are beneficial, it’s important to note that their unique bit-accepting mechanism is only compatible with hex-shaped bits. Thus, an impact driver is not the most fantastic option if you are working on a project that requires you to often switch between different bit shapes.

Of course, hex-shaped bits are popular and widely used, but they aren’t the only kind of bit you may utilize. You’ll need a standard drill or a hammer drill, both of which accept a wider variety of bit shapes and sizes than a hex drill.

Screws that are too short

Screws that are too short

We get it; impact drivers are the go-to tools for driving lengthy screws and bolts into rigid, thick materials like oak and brick. Why? The enormous torque and impact produced by impact drivers allow for the driving of very long screws into particularly thick materials.

However, if the nuts are too small, you risk damaging or ripping them because of the impact driver’s tremendous torque and force and your lack of control. If the screw is particularly short, the impact driver’s high torque might cause it to turn at an excessive pace.

Do not overtighten fasteners, since this can cause the materials they are combining to shatter. To illustrate, if you drive a screw into a piece of soft wood with excessive force, the wood may break. That’s why you should never use an impact driver to secure short screws, especially when working with very delicate materials.

Soft Materials

Keep in mind, too, that impact drivers aren’t the best choice when working with softer materials. Their high levels of torque and power make them perfect for use on hardwood, stone, metal, and other similar materials. However, an impact driver is not the best choice if you need to work with delicate materials, such as softwood.

As we saw before, this is for similar reasons. Since impact drivers have so few degrees of freedom, they are notoriously inaccurate. In addition, it can harm softwood by using too much torque when inserting a screw fastener.

If you’re working with fragile materials, you’ll require similarly sensitive equipment. Using an impact driver on soft materials is not only highly abrasive but also pointless. To drill or screw into softwood, a standard drill/driver should be used.



The advice to exercise caution while using an impact driver on hardwoods like oak, maple, or birch should be taken with a grain of salt. Due to the high torque produced by impact drivers, screw heads often crack when pushed into more robust materials.

Although you may use an impact driver to secure hardwoods, you should take extra caution when the screw head is close to the wood’s surface and easily breaks off.

Over-tightening screws in softwoods are less likely to result in the screw head breaking off since the wood has more excellent give.

Using an impact driver to drill precisely is made more difficult by the tool’s lack of control. Lastly, these instruments’ incredible force and torque make it possible to over-drill a hole and make it too deep. Therefore, using a standard drill when making holes is always preferable, especially wood.

Exact Work

Any operation that requires accuracy, especially if it involves little pieces of material, is not a good candidate for an impact driver. In addition, although impact drivers can generate excellent torque, they can be challenging to handle because of their jarring back-and-forth motion.

It would be tough to use an impact driver to drill a straight hole in thin and fragile material, specifically if the hole were skinny. In addition, a standard drill driver is like a targeted attack with no collateral damage, whereas an impact driver is more like a tremendous explosion that destroys everything in its path. Therefore, an impact driver is not a tool to use for delicate or precise work.

Drill Holes

Drill Holes

However, drilling holes is another job that is not best accomplished with an impact driver. Even while impact drivers have the capability of drilling holes, this is not their intended use. Holes may be drilled with either a hammer drill or a standard drill driver. The fact that impact drivers can only use bits with a hex form is only one of many reasons why they shouldn’t be used to drill holes.

Standard Bits

Standard Bits

Another time a regular bit might be more appropriate than an impact driver is when you need to use that bit. But unfortunately, regular bits won’t fit in the quick-change holders of most impact drivers because they aren’t designed to accommodate the hex shape of the bits used in those drivers.

You shouldn’t be shocked if a standard bit with a hex end breaks in half when used in an impact driver.

Benefits of an Impact Driver

After reading this manual, you might notice that impact drivers have several drawbacks. However, the benefits will show how extensively an impact driver may be used. With this information at hand, you’ll be able to clarify, “When do I want to use an impact driver?”?”

Greater Force

To loosen the screw, you just need to blow into it around fifty times, making it one of the most crucial characteristics. Compared to standard drill drivers, impact drivers pack five times as much punch. As a result, this driver is the best choice for the most rapid of tasks.

Bits for Impact Drivers

Drilling may be accomplished with impact driver bits. Drills and drivers with a 1/4″ hex shank can be the best choice for a rapid and profound torque operation.

A Smaller amount of Recoil

Its ability to dampen recoil is superior to that of similar drills. Impact drivers are easiest to handle if they recoil less forcefully.

Simply put, it’s a breeze to use

It’s lighter than standard hammer drills, so you can hold it for longer without becoming tired. In addition, its shorter head compared to the standard cordless drill provides a better grip. Finally, it’s convenient for usage in cramped quarters.

Impact Driver’s Drawbacks:

  • Compared to other drills, this one is more expensive.
  • Drill bits of varying sizes cannot be stored in them. This exercise requires less precision than the others.
  • The torque power of this is inadequate.
  • This drill has a less powerful magnetic mechanism for gripping screws than others.
