8 Best Impact Wrenches for Changing Tires [2022 Updated ]

Most of the models in our ranking are intended for hobby use, of course, but some offer above-average performance. In addition there is also a professional model, ideal for mechanics and tire specialists.

1. DEWALT 20V MAX* Cordless Impact Wrench

 
Although the Teccpo company has only recently appeared, it has already gained considerable fame in the production sector of power tools for hobby and artisanal use, and is already in competition with the historical brands in the sector.

The TDIW01P, in fact, ranks first among the best impact wrenches of 2021, bypassing even those produced by the most famous companies, thus making it one of the best-selling models online.

  • Compact (5.70" front to back), lightweight (3.4 lbs) design fits into tight areas
  • Three (3) LED lights with 20 second delay after trigger release, provide visibility without shadows
  • Hog ring anvil to easily change sockets
  • Textured anti-slip comfort grip provides maximum comfort and control


Its great success on the market is mainly due to the performance offered, which with a tightening torque of 350 N m, are very respectable, and to the completeness of the package, which contains the screwdriver, the battery, the battery charger, three spanners. compass and the rigid case to keep everything and transport it if necessary. The only flaw is the lack of a power regulator; nevertheless, its performance has satisfied even the needs of professional mechanics.

Pros

Powerful: Despite being a cordless impact wrench, the TDIW01P is characterized by a very high power level, with an N · m coefficient higher than that of many professional category pneumatic models.

Performance: The 4Ah 18V battery offers enough autonomy to withstand an entire day of work in the workshop at a fast pace; this aspect, combined with the power, surprised even the professional user segment.



Complete: Cordless impact wrenches are usually sold without the battery, which must therefore be purchased separately; the Teccpo, on the other hand, is complete with everything: battery, charger, socket wrenches and hard case.

Cons

Regulator: Unfortunately the regulator is missing, so the Teccpo always works using the maximum of its power and tightening torque.

2. Milwaukee 2962-20 M18 18V Fuel 1/2″ Mid-torque Impact Wrench

 The Milwaukee M12BID-0 is another battery-powered model and is appreciated by both the hobby and professional users, especially thanks to the fame of the US brand.

The strengths of the impact wrench are the extremely compact dimensions, which allow it to be used even in confined spaces, the compatibility of the coupling, which allows you to use the batteries of other Milwaukee power tools belonging to the M12 line, and the price, which it is on average accessible. It is also equipped with LEDs to illuminate the work area, REDLINK circuit to protect the tool and battery from overloads and an ergonomic handle; the tightening torque, however, is limited to just 112 Newton per meter.



The only flaw, according to the buyers’ opinions, is the total absence of accessories; if you do not already have other Milwaukee M12 power tools, in fact, you will be forced to buy the battery and the charger separately.

Pros

Reliable: The Milwaukee brand is a guarantee at every level, both amateur and professional; and in fact this impact wrench is characterized by excellent performance, moreover the REDLINK technology also protects the battery from overloads.

Compact: The small size and economical handle allow it to work even in the tightest spaces, making it particularly suitable for home use and as an emergency equipment in the car.

LED: Unlike other impact wrenches, this one also has a handy LED to illuminate the work area, so it can also be used in poor visibility conditions.

Cons

Accessories: The battery, the charger and any case must be purchased separately, thus further affecting the overall cost.

3. Toolman Lithium-ion impact wrench

 
In comparison to the Milwaukee examined previously, the TD110DZ is the model that comes closest, both in terms of performance and in terms of technical characteristics. The Makita impact wrench, in fact, is a battery-powered model with compact dimensions, equipped with an ergonomic handle covered in soft rubber to increase comfort and grip on the tool, and even equipped with a LED to illuminate the area of work.

How to choose the best impact wrenches

The electric version of these appliances has only appeared in recent years, so it is still difficult for many to pinpoint which impact wrench to buy. The confusion is mostly generated by the power tool’s power and its actual capabilities.


Basic features

To understand how to choose a good impact wrench you first need to know how it differs from normal electric models and why power is so important for the intended use.

In fact, this tool, until a few years ago, was used exclusively in the industrial sector, in mechanical repair shops and in those of tire specialists; the devices used, moreover, were all pneumatic, that is, operated by compressed air. In recent years, however, thanks to the advent of induction electric motors and the technological evolution of batteries, it has finally been possible to create compact electric impact wrenches capable of generating a torque that, in some cases, is similar to that of professional compressed air models.

The advantage of electric impact wrenches, especially battery-powered ones, lies above all in their easy handling and full freedom of use; but most of the models found in the low-medium price range are intended for hobby and amateur use only. Those intended for professional use are particularly expensive, because they are able to generate a much higher tightening torque.

The tightening torque

The tightening torque is nothing more than the force applied to the torsion of the screw, or bolt, and is measured in Newton per meter, indicated by the abbreviation N · m.

The torque generated by a traditional screwdriver can vary from 20-60 N · m for hobby models up to 60-120 N · m for those intended for professional use; Impact wrenches, on the other hand, far exceed these values ​​and are characterized by a significantly higher torque.

In this case, in fact, it starts from about 110-400 N · m generated by the hobby models, up to 1,500 N · m and over for models intended for professional use; however, even impact wrenches capable of generating a torque between 300 and 600 N · m can usually be used in a professional environment, especially in small mechanical repair shops and tire shops.


The supply of accessories

An extremely important aspect that must be paid close attention when choosing an impact wrench, especially a battery-powered model, is its range of accessories. It is good to be prepared for the idea that this type of equipment, in fact, is more expensive than traditional ones, and that the expense can further increase if the batteries and other accessories are to be purchased separately.

The cheaper models completely devoid of accessories, except for some sporadic cases in which the case, a few socket wrenches and some bits are included in the package; therefore the battery and its charger are to be purchased separately in most cases.

It is obviously possible to find kit packs that also include the battery and its charger, as well as an initial set of socket wrenches of different sizes and maybe a few bits, but you must necessarily move on to products belonging to the medium-high price range.

How the impact wrench works

The characteristics of the tool

In traditional screwdrivers the tip is driven by a shaft which is subjected to continuous rotation by the electric motor; the power generated by the motor, therefore, is applied entirely to the rotation of the shaft, which is why part of the same is dispersed instead of generating torsional force for the tightening torque.

In the impulse version this does not happen, as there is a mechanism that allows you to exert a greater pressure on the shaft, thus generating a greater torsion force.


The principle of operation

The primary elements underlying this mechanism are a compression spring, a weight, also referred to as an impact mass or striking mass, and a small T-shaped anvil. When the spindle is rotated by the motor, initially the compression spring and the striking mass rotate at the same speed; as soon as the weight begins to hit the anvil, however, the latter opposes a resistance to the striking mass, which consequently begins to rotate with a slower speed than that of the motor and the compression spring.

The difference in rotation speeds allows the spindle to rotate faster than a traditional screwdriver; the pressure that the striking mass generates on the anvil is also transferred to the tip, increasing the perpendicular pressure generated on the anvil, thus producing a greater tightening torque.

The friction

The high tightening torque of impact wrenches is ideal for minimizing effort when driving very long screws, or when tightening nuts or bolts. This tool, in fact, performs all the leverage work that is usually done with the arm, but in a much more efficient way and applying greater force.


Precisely because of the high power, however, it is easier to run the risk of breaking the screws or damaging the thread, to avoid this type of problem you can adjust the torque using the clutch mechanism.

In the cheaper models intended exclusively for hobby use, the clutch is usually automatic and acts autonomously, adapting according to the resistance that the screw or bolt has to torsion; in the medium-high range impact wrenches, on the other hand, the clutch can be adjusted manually and therefore optimally adapted to the type of work to be performed.

Frequent questions

What does an impact wrench mean?

The definition derives from the same operating principle on which this tool is based; inside, in fact, there is a mechanism consisting of a spring, a weight and an anvil. When the motor is activated, the spring transmits the rotation movement to the weight, which begins to beat quickly on the anvil; the latter, in turn, transfers the pressure of the blows received to the spindle, in the form of impulses.


What is the purpose of the pulse screwdriver?

The operating principle on which the impact wrench is based allows it to generate a much higher tightening torque than traditional models, consequently this tool is mainly used to tighten or loosen very long nuts, bolts and screws, which usually require the application of considerable force.

This makes it especially useful for mechanics and tire specialists, as well as for industrial workshops where it is used for the assembly and disassembly of engines, wheels and other mechanical components. The versions for hobby use, on the other hand, are used for home maintenance of the car or other vehicles, or at a handicraft level, for the assembly of furniture, shelves, shelves and other objects.

How much does an impact wrench cost?

The price of an impact wrench can range from around 60-100 euros for the cheapest models up to 1,500 euros and more for models intended for professional use. Other aspects that may affect the price are the supply of accessories and the type; on the market, in fact, you can find both pneumatic impact wrenches, operated by compressed air, and electric ones, and the latter can be powered either by cable or by battery.

What kind of impact wrench is good for changing wheels?

In general, the tightening torque of the bolts that secure the wheels of the car can vary from approximately 95 to 200 N · m; the exact specifications are given in the vehicle’s use and maintenance manual, but in the absence of the latter they can be established by using a torque wrench. If you want to buy an impact wrench for home use, therefore, to be used for the maintenance of your car, you need to choose a model that has a tightening torque between 100 and 300 N · m.

Where to buy an impact wrench?

This tool can be easily found at any well-stocked hardware store, or at a specialized dealer; in-store prices, however, may be slightly higher than the purchase options provided by the internet, where it is possible to go directly to the stores of the manufacturers or to e-commerce sites, such as Amazon.
