The best cordless impact wrenches are also known are impact guns, air wrenches, rattle guns, impactors, windy guns, etc. The socket wrench has a socket at the end that is used to turn a fastener such as nuts and bolts. The torque to fasten or unfasten a nut or a bolt may be delivered by power. Thus an impactor is a power tool designed to deliver a high torque to reduce the exertion for the user. It stores energy within a rotating mass and delivers it via an output shaft. The most common power source is compressed air but hydraulic power and electric power are also used. Battery powered devices have become popular since the mid 2000s.
How does an Impact Wrench function?
The impact wrench functions by storing potential energy in a rotating mass that releases it in small impacts against the output shaft. This puts a lot more force against the nut of bolts you are trying to tighten or loosen and takes the strain off your wrist.
The bit sits still on the nut and turns only when the hammer hits the bit at each turn when it engages with the output shaft.
The output shaft is fitted with a hammer and spring in series. The spring loaded hammer lifts up, spins around to be driven down by the spring and forward by the drill at high speeds.There are slots cut into the hammer that slide onto the output shaft.
Springing the hammer on to the output that transfers the impact and torque to the bit that turns the nut or bolt you are trying to tighten or loosen. The motor generates high amounts of torque much more than any human can produce. This hammer shaped mass continues to turn thus the operator feels only a tiny impact.
Uses of best cordless Impact Wrenches
Impact wrenches are used in automotive,heavy equipment, repair,production assembly, maintenance, construction industries. These industries require high torque output thus a tool with reactionless tightening reduces the noise level too. The kinetic energy is transferred using oil from the hammer to the anvil.
This also gives a lower torque to weight ratio, a smoother impulse besides a shut off mechanism if the tool does not achieve the correct torque.These tools can turn a lug nut on a wheel to the largest fasteners on a construction site.
The wrenches are versatile as they are available in all standard sizes of standard socket wrenches and driver sizes. These may be from 0.25 inches for tools used from assembling and disassembling to 3.5 inch and larger square drives used for construction and heavy duty jobs.
Types of Impact Wrenches
There are pneumatic wrenches that are driven by compressed air. These wrenches have different drive sizes to deliver different torques. Usually the higher the drive size the larger the torque produced. They come in various sizes such as 0.25 inches, 0.375 inch, 0.5 inch, 0.75 inch and one inch. A one inch drive produces a torque of 3000 feet per pound.
Hydraulic impact wrenches are used with hose sets to take the tool away from the source of the power or the pump. These wrenches are used for tightening, drilling, loosening hardware and poles. Some of these power wrenches even function underwater.
Corded electric impact wrenches are powered by an electrical source.
These wrenches run on AC and DC, but are rare as most manufacturer now make cordless ones. They come with 0.50 and 0.75 inch drive sizes. These wrenches have a longer body to accommodate the motor to produce the torque.(we have written extensively for the best generators brands)
The cordless electric wrenches are powered by rechargeable batteries. These batteries are usually 18 to 28 volt nickel-cadmium or lithium-ion batteries. The advantage of using cordless wrenches is that they can be used anywhere due to the portable power source. They are heavier than pneumatic and electric impactors due to the on board batteries. They are sustainable as they can be recharged and compact in design.
It is helpful to understand this fact before buying a best cordless impact wrench that is less powerful than comparable tools that run on compressed air. But these battery powered tools generate sufficient torque for jobs around the house, making them perfect tools for the garage, car trunk , RV , tool-shed, DIY projects around the house. Due to their compact size and shape they are perfect for small jobs in narrow spaces. They are right for spaces too tight for power cords.
Features to look for in your Cordless Impact Wrench
Source of power would be battery-operated using nickel-cadmium or lithium-ion batteries.
Torque is the influence or impact that changes the rotational movement of a mass. Thus higher the torque the more powerful the influence on the nut or bolt. Torque is counted in hundreds and should not be less than 200 and above is a good figure.
Rotations Per Minute (RPM) should be 3000 and above as the tool depends on rotations to do its job. It turns to wind or unwind the nuts, bolts and screws. The higher the number of turns and more powerful the torque the lesser the effort on the part of the user.
Impacts Per Minute (IPM) or Blows Per Minute (BPM) occur while the hammer rotates to turn the drivers to screw or unscrew the nuts and bolts. The higher the IPM the higher the contact between the target and tool embedding the lug or screw firmly into position.
Now that we have selected the type of impact wrench
We want to buy let us consider the features we may want on it.Shape of impact wrench affects the grip on the tool. There are inline wrenches and pistol wrenches. The impact wrenches are shaped like an oversized screwdriver. This means that the grip points are located right behind the anvil and hammer. In the pistol shaped wrenches the grip is under the torque generating parts.
Socket sizes vary to fit various sizes of bolts and bolts. The socket sizes corresponding to the shapes of impact wrenches are as follows the socket size of 0.25 inch fits inline and pistol wrenches. The 3/8 inch fits the pistol and butterfly wrench, a form of inline wrench. The ½ inch socket is for the pistol wrench and the ¾ inch fits into the pistol wrench. The one inch socket fits into a pistol wrench and a T-shaped inline wrench with handles at the other end of the anvil.
Comfort and durability may be improved by the ergonomic design of the tool. The materials used to make the tool and the components used. The design of the components and their engineering grant optimum functionality and performance to the tool. This in turn improves the comfort of use. The materials used grant durability delivering the value for you money.
