How Does a Cordless Impact Drill Work?

If you’re working on a difficult project like a building, carpentry, or decking, you’ll need an impact drill.  Cordless impact drills, also known as impact drivers, are hand-held instruments that are used to quickly drive screws.  This is a heavy-duty screwdriver made for working with denser, heavier materials and for longer periods of time.
Impact drivers use a percussive force comparable to that of a hammer drill to help drive screws quicker and deeper into denser materials.

What is the Function of a Cordless Impact Drill?

A cordless impact drill works similarly to a drill, except that when the driving motor detects resistance, the impact hammer mechanism is activated by pushing an internal spring back, causing the hammer to dive forward and strike the anvil.

This mechanism significantly increases torque, allowing you to drill screws through dense, resistant materials with ease.

One thing to keep in mind is that because they don’t have a clutch like a cordless drill, you’ll have to experiment and practice drilling screws to get the right depth. Although there isn’t much of a learning curve here, it’s worth noting.

When using an impact driver, you can connect bits by sliding a 1/4-inch fast connect chuck forward and attaching your bit. It is then secured in position, and screws or nuts can be drilled or fastened as needed.

 Cordless Impact Driver vs. a Cordless Drill

The majority of the output torque from a cordless drill is applied directly to the bit, whereas the torque from an impact driver is applied in a perpendicular direction. As a result, switching from a drill to an impact driver makes the mode of action more challenging.

The cordless drill’s sweet spot, from a practical standpoint, comprises uses such as:

  • Hole-drilling in a soft substance
  • Screwing soft material with screws, although on a small scale
  • Bolts that don’t require a lot of torque are loosening and tightening

It’s safe to conclude that cordless drills perform better in jobs that need drilling and pushing screws into soft material at a consistent rate. This comprises the following in the event of an impact driver:

  • Large-diameter fasteners must be driven.
  • Screwing into thick materials
  • Working on bolts that are stuck or have a tight fit
  •  Other applications that call for a large number of screws to be driven fast without consideration for their depth on the surface.

Differences Between Cordless Impact Drills and Impact Wrenches

Impact wrenches are larger, heavier, and significantly more powerful than impact drivers (in terms of output torque). Impact wrenches have approximately 7 times the power of impact drivers. Moreover, impact wrenches make use of a square drive (1/2 inch), typically used for sockets, and are made for fastening and loosening bolts. Most impact drivers, on the other hand, utilize a 0.25-inch hex drive to drive screws and bolts or drill holes, which can be used with any bit or socket with a hex shank.

Impact drivers may be used for a wide range of tasks (more on this later). Due to the tool’s great level of force, you should only use impact wrenches for certain high-power jobs like assembly and maintenance of machinery.

Cordless Impact Drill and Hammer Drills Comparison

Cordless Impact Drill VS Hammer Drills

Cordless Impact Drills vs. Hammer Drills

The type of force employed by a hammer drill and an impact driver is the fundamental distinction. When more power is required, hammer drills utilize a pounding action, as if a hammer were hitting the drill’s rear. As the drill spins debris out of the hole, this movement provides the necessary penetration to push the fastener through a hard material. Bolts can be driven into concrete, brick, masonry, or heavy metal using hammer drills.

An impact driver, like a cordless drill, employs rotational force to drive a screw and stores its bursts of high power until it encounters resistance. When working with wood, you’d use an impact driver for lengthy screws or heavy fasteners. An impact driver is also lighter than a hammer drill, making it more maneuverable.

Drilling Concrete with Cordless Impact Drill

While you can drill a few small holes with a 5-6mm masonry bit on a 1/4-inch hex shank, that’s about the most you can expect for when it comes to drilling concrete with a cordless impact drill.

How to Drill Concrete with an Impact Driver:

It is feasible to do the task if you just need to drill one or two holes in concrete and already own an impact driver. It takes a little more time and work, but it can be worthwhile for a minor project when you don’t want to invest in another power tool.

Here’s how to drill through concrete using cordless impact drill:

  • Use masonry bits with a cordless impact drill. Get a complete set of masonry bits made for use with an impact hammer. Drill bits not designed for use with an impact hammer may break or shatter, thus they should not be utilized for this task. You’ll need to gradually expand the diameter of your hole until it reaches the necessary diameter, so purchase a set of bits that lets you to do so an eighth of an inch at a time.
  • Mark the center of the hole and drill it with your smallest masonry bit, using mild but consistent pressure. Reduce pressure if you feel the drill resisting.
  • If the tool starts to bind, stop. Drill to the same depth by increasing the size of your drill bit by one increment. If the tool becomes stuck again, place a hardened nail into the hole and hammer it to break up the concrete within.
  • Drill to the appropriate depth with that diameter and try to maintain the cordless impact drill as stable as possible to avoid breaking the drill.
  • Gradually increase the depth and diameter of the drill bits by one-eighth of an inch at a time until you reach the required depth and diameter. If required, re-nail and re-hammer the concrete to break it up and allow the drilling to continue.

📌As you can see, drilling into concrete using a hammer drill or rotary hammer is slower, more arduous, and perhaps less exact.

📌If you don’t have access to a hammer drill or rotary hammer, it’s a less expensive option that’s worth a go. Remember to use the suitable drill bit while using your impact driver or even drill driver.

Impact Drills’ DON’Ts

A cordless impact drill, unlike a small drill, has no selectable speeds or settings and is all or nothing. As a result, if accuracy is required, this is not the instrument to use. Limit the usage of an impact driver to tasks where the size or location of the hole is less important than the amount of torque required to complete the task. Impact drivers are also ineffective when drilling into hard materials like brick or concrete. Choose a hammer drill for this.

🔸 Cordless Impact Drills; Designed for Driving

Cordless impact drills are used to drive fasteners rather than drill holes. In a hurry, you can use a regular hex-shank drill bit to drill a hole in light-gauge steel or softwood provided you have the right bit. However, if you wish to drill a hole larger than 14 inches in a thicker or denser material, you’ll require an impact driver bit. Otherwise, the driver’s increased torque will snap the bit.

🔸 Attention DIYers, start with a drill, then upgrade to a cordless impact drill

That is dependent on the sort of DIY tasks you want to undertake. A low-cost drill, on the other hand, should suffice for simple house repairs. Drills may be used in a variety of ways. Some include additional speed and torque options, as well as an impact setting. They can also handle a wide range of modest tasks due to their ability to employ a number of bit types.

Experts believe that you should start with a drill when expanding your tool collection. However, if you’re a serious DIYer, adding an impact driver will give you the tools you need for practically any job.

 Drill And Its Bits

🔸 larger projects cordless Impact drill

A cordless impact drill is used for anchoring the beams of a pergola by driving nuts. It’s the tool to have on hand for any project that calls for lengthy screws or bolts. In addition, while dealing with pressure-treated timber, hardwood, or heavy steel, the driver has the necessary torque to easily cut through the material.

Choosing the Best Cordless Impact Drill:

We’ve covered all of the key features and options that set cordless impact drills apart from other drill kinds. However, you may still have reservations about cordless impact drills. As a result, we’ve put up a comprehensive feature guide for the finest cordless impact drills, by reading this guide you’d know what to look for in a cordless impact drill before making any purchases.

1. Chuck Size

The chuck size given by different cordless impact drills is the easiest method to distinguish between them. As you might assume, a bigger chuck size gives you more options when it comes to the bits you can use with your impact driver.

Most impact drivers come with chuck sizes as small as 14 inches and as large as 12 inches. And, for the most part, the 12 inchs chuck size is the preferable choice for most people. It may be used with both tiny and big driver bits without any problems.

2. Battery Voltage

When we say cordless impact drills, it means that they do not require a power outlet to operate. However, because their motors require electricity to operate, they rely on a battery to keep them running while cordless.

As a result, a cordless impact drill’s battery must be strong enough to power the motor while also allowing you to screw nuts and bolts. These impact drivers’ batteries are generally 18V or 20V, with a cordless impact driver with a 20V battery being the superior option.

3. Battery Life

The battery life of your cordless impact drill is another key factor to consider. It simply indicates the maximum length of time a cordless impact driver may be used. Despite the fact that most cordless impact driver batteries can be readily replaced, you should choose for one with a long battery life.

It enables you to use the impact driver for an extended period of time without having to replace the batteries. In most cordless impact drill choices, the battery life is specified as 1.5 Ah or 2.0 Ah, with the 2.0 Ah battery providing greater working duration.


4. Motor Speed

After you’ve examined the battery power of a certain impact driver, be sure it has a strong motor. Screwing nuts and bolts successfully necessitates the use of a strong engine. The simplest approach to determine a motor’s power is to look at its motor speed.

The motor speed of a cordless impact drill is measured in RPM, or rounds per minute, just like that of other power tools. And separate impact drivers have motor speeds of 2000 RPM or 2500 RPM, with the 2500 RPM motor being the speedier choice.

5. Size and Weight

One of the finest features of impact drivers is that they can be used on the move without causing any problems. However, you should verify the size and weight of your cordless impact driver to ensure that it can be used without difficulty. An impact driver with a modest size may be utilized with ease. When not in use, it also takes up less room in your toolbox or garage.

Another significant consideration is the cordless impact driver’s weight. Lightweight cordless impact drill may be used for extended periods of time without causing hand soreness or other problems. It also makes it easier to transport without adding too much weight to your toolbox or bag.

6. Accessories

There are several cordless impact driver alternatives available. A lot of these alternatives also come with a lot of extras right out of the box. These add-ons can be quite useful in improving your overall experience. Carrying bags, batteries, charging kits, driver bits, and other cordless impact drill accessories are available.

While these factors do not have a direct bearing on the performance of a specific impact driver, they do improve the overall experience. And if a cordless impact driver comes with any of these extras, it implies the user will get a lot of bang for his or her buck.


7. Durability and Reliability

The majority of cordless impact drivers are frequently utilized to screw various types of nuts and bolts. As a result, the impact driver may experience significant wear and tear over time. As a result, you should invest in a cordless impact driver that is long-lasting and dependable. Checking the guarantee duration supplied by a certain cordless impact drill is the simplest approach to ensure that it is durable enough.

There are cordless impact driver alternatives available with a two-year or three-year guarantee period. However, other alternatives come with a 5-year warranty, and in some circumstances, a lifetime warranty. As you can think, such cordless impact drills can easily survive a long period without causing any problems.

Is it possible to use an impact driver to drill holes?
Yes, an impact driver may be used. The drill bit is the most significant factor. You may use an impact driver to drill tiny holes in light-gauge steel and soft wood with a conventional hex-shank drill bit, but you’ll need a bit certified particularly for impact drivers if you want to drill holes bigger than 14 inches in heavy steel, hardwood, or pressure-treated timber.

Is it possible to remove lug nuts using an impact driver?
Technically, yes. To attach a lug nut socket to the tool, you’ll need to utilize a hex shaft to square drive adapter. An impact driver, on the other hand, may not have enough torque to break loose a rusted/frozen or overtightened lug nut.

When is it better to use an impact driver instead of a drill?
Except for extremely short fasteners, use the cordless impact drill to drive most fasteners. An impact driver is especially useful for tasks like driving 3-inch screws into wood, which is difficult to do with a drill even when the hole is pre-drilled. Impact drivers are very good at pushing screws into knotty or solid wood.

Conclusion 🧾

A cordless impact drill is incredibly flexible, which is why it’s often the first power tool that people buy—hard it’s to match its value for drilling pilot holes and driving screws. To the untrained eye, a drill or impact wrench may appear to be the same, but they are fundamentally distinct instruments, starting with how their bits are loaded.
It all comes down to your specific demands when deciding between an impact driver, cordless drill, or impact wrench. In a nutshell, for home-related jobs, choose for a cordless impact drill, which is particularly intended to drive screws and bolts that would otherwise stall a cordless drill.
