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.
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 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.
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.
