IMPACT DRIVER VS IMPACT WRENCH

Once considered a tool solely for professional contractors, impact drivers have now become extremely popular with everyday DIYers for their power and portability.

But what about impact wrenches? While they are mandatory for pit crews pursuing pole positions, are they really as useful to have around the house?

And if you already own an impact driver, do you need an impact wrench, or can one tool do both kinds of jobs? 

Since they are both high-torque power tools that look darn near identical in appearance, how are they actually different? And do you really need both?

IMPACT DRIVER VS IMPACT WRENCH FOR HOME USE

While impact drivers and impact wrenches use the same principles in operation, they are used very differently and have distinctly different applications.

An impact wrench delivers many times more torque than a impact driver, usually hundreds of pounds more. They are used professionally on heavy equipment and throughout the construction and automotive industry.

For most homeowners or DIYers, the most common applications for impact wrenches would be in the garage, if you had to do some more serious work on your prized pride and joy or dirt bike.

Impact wrenches are a tool that you just can’t do without if you’re a car enthusiast who’s constantly tinkering and tweaking with engines. 

Impact drivers, on the other hand, are increasingly popular for DIY and home projects. While they aren’t as versatile as the likes of a cordless drill, they are great for building decks, sinking screws rapidly, general home repair works, and can even remove stubborn lug nuts (more on that later).

IMPACT WRENCH VS IMPACT DRIVER

The main difference between an impact driver vs an impact wrench is the amount of high-impact force an impact wrench produces, and the fact that impact wrenches utilize a square drive while impact drivers make use of a 1/4-inch hex collet.

In terms of either tool’s application, one is designed to tighten or loosen tough nuts and bolts, and the other is used to drive screws and fasteners.

The truth is, most average homeowners won’t have that many jobs around the house that require an impact wrench.

Since an impact driver can be used to tighten and loosen lug nuts and do other light automotive repair works, it’s usually perfectly adequate for most needs, and a much more versatile tool to have around the house.

Also, for mechanics and professionals in the metal fabrication industry, who need hundreds or thousands of pounds more torque delivered at high speed, an कारगर रिंच is part of daily life.

WHAT EXACTLY IS AN IMPACT DRIVER?

While an impact driver might seem similar to a cordless drill and look nearly identical to an impact wrench, they are markedly dissimilar in functionality.

An impact driver is a power tool designed to deliver high torque and or rotational force. The impact is a strong, repeated, rotational hammering force (rather than constant forward force), and they have been specifically designed for driving and fastening with speed and power.

Impact drivers have a 1/4-inch hex socket, with bits specially designed for the additional stress that an impact driver places on a bit.

Also, just remember that when you’re buying an impact driver, you’ll be somewhat limited in terms of what you can actually drill. Honestly, if you’re looking to do more than drive screws or fasten nuts and bolts, you’ll need to get yourself a cordless drill driver.

WHAT CAN YOU USE AN IMPACT DRIVER FOR?

An impact driver is typically used for driving screws and drywall anchors into heavy-duty materials like studs and sheet metal.

Impact drivers are smaller and less versatile than cordless drills, but deliver a lot of torque, which means additional power to drive long screws into tough materials quickly, with less effort from the user.

You can also use impact drivers for drilling holes with a 1/4-inch hexagonal shank and bit drill to suit. If you’re just drilling a few holes into wood, plastic, or aluminum, you’ll have very little trouble.

Although once you go beyond 1/4-inch by utilizing adapters and attempting to drill into heavy metal or hardwood, you’ll definitely need bits rated specifically for an impact driver.

WHAT IS AN IMPACT WRENCH?

Just like impact drivers, an कारगर रिंच is a high-torque tool. Most impact wrenches have a square drive and deliver percussive rotational force.

The best way to imagine what an impact wrench does is to imagine that you are trying to loosen a big, tough bolt.

If your standard socket wrench isn’t working, you might attach the wrench to the bolt, and then hit the wrench with a hammer, to apply percussive torque that loosens the bolt.

An impact wrench does precisely that, as the wrench impact mechanism hammers against the output shaft producing an enormous amount of torque.

WHAT CAN YOU USE AN IMPACT WRENCH FOR?

Impact wrenches are designed to apply a lot of force to fastening or loosening sockets, rather than driving screws.

They are so powerful that they are typically associated with heavy-duty automotive and construction equipment work, with oversized, very tight sockets and bolts that are difficult to loosen and tighten correctly.

Now while you can use an impact driver to tighten or loosen bolts, an impact wrench is specifically designed for this purpose and harbors a much greater degree of torque and power.

The average impact driver’s torque output is around 110 ft-lbs, while the typical impact wrench punches out around 700 ft-lbs.

That’s a considerable difference in torque and the power out between an impact driver vs an impact wrench is defined by their practical application.

In short, you simply do not need the level of power and torque from an impact driver to drive screws, but for removing a 10-inch prevailing torque nut on the foot mount of a motor, you’re going to need that extra juice and larger square drive to get the job done.

IN CONCLUSION

As with almost all power tools, whether it’s a conversation about an impact wrench vs impact drivers, all of these power tools are designed for different specific tasks and are used in a variety of varying circumstances. 

Now you know the differences between impact drivers vs impact wrenches and the most common household applications for each of the power tools; you can now confidently decide which one would better suit your needs, and which one is worth the investment.

Also, while you really could just get one tool or the other (likely an impact driver) if you’re a DIY weekend warrior, you might be better off considering a combo option and getting both tools if you’re a professional contractor.
