Solved! What Is an Impact Driver?
Jul 22, †Ј Like the cordless drill, an impact driver uses rotational force to drive a screw and saves its bursts of quick power when it feels resistance. You . Impact drivers are designed for efficiently driving long deck screws or carriage bolts into wooden posts, fastening concrete screw anchors into block walls and driving screws into metal studs. .
A cordless impact driver is a power tool. It runs on battery power, which is why it can be operated without a cord.
The lack of a cord also allows users of these drivers to be able to get into tight spaces and to avoid being near a power supply. The main job of a cordless impact driver is to drive in screws. But it can also be used for turning bolts and nuts. A cordless impact driver is especially good for long screws, and they tend to be used when a screw needs to be driven into a very tough or hard material.
The reason why a cordless drill driver can carry out each of these tasks is that it produces a very high amount of torque. Cordless impact drivers tend to be lightweight power tools.
Many people get confused between cordless impact drivers and cordless drills. They look the same. And there are some tasks that you can use both for. The biggest difference, however, is that a drill is primarily used for boring holes into things, such as walls or ceilings. A cordless drill will also have a battery pack to power it, and it may also offer you different torque settings how to make a simple pin hole camera that you can alter it for your different purposes.
A cordless drill can also be used to drive in screws. But a cordless drill lacks the same torque as a cordless impact driver. So, you may be able to use it for small screws, but longer screws will not be able to be driven as easily and successfully into hard materials, as they would be if you use a cordless impact driver. Also, the higher amount of torque that a cordless impact driver is capable of producing means that it functions a lot quicker than a cordless drill can, even when doing the same task.
So, we know now that a cordless drill can be used for driving some screws and for tightening some nuts, but can a cordless impact driver be used for drilling? Yes and no. Basically, it is possible to use a cordless impact driver to bore holes into things. You would need to find a drill-bit that will fit inside the chuck. You might also be more likely to lose control over a cordless impact driver when you use it as a drill, causing a lot more damage again.

TheyТre able to put out an impressive amount of power into the work without having it affect your . Impact drivers are small, cordless drill like tools, that are used to loosen screws and nuts that are unable to be taken out by a traditional screwdriver. They are also used to tighten screws and nuts that need to be tightened with more torque than can be provided by a screwdriver. Impact drivers are stubby with a shorter head.
An impact driver is a power tool that provides high torque to loosen or drive-in screws that are jammed due to rust or over-torqued. In this guide, you are going to learn all you need to know about impact drivers. When you think of iconic, must have power tools that you will find in every garage, what do you usually think of?

Impact drivers are small, cordless drill like tools, that are used to loosen screws and nuts that are unable to be taken out by a traditional screwdriver. They are also used to tighten screws and nuts that need to be tightened with more torque than can be provided by a screwdriver. Impact drivers are stubby with a shorter head.
Another key difference is that the impact drivers have hexagonal-shaped collets instead of a traditional 3 jaw chuck. But you must get drill bits with hexagonal shanks which usually are not available in smaller increments in diameter. This powerful tool was once considered a specialty tool, only used by serious contractors and professional carpenters.
However, with the rising popularity of DIY do it yourself home repair, it has become more common to keep a cordless impact driver around the house. They can be used on a wide array of jobs; everything from building decks to tightening some screws around the house can be made easier by having an impact driver.
But there are some cases where impact driver performs exceptionally well. Impact drivers are highly useful for construction workers, cabinet makers and jobs that require the use of a large number of fasteners. Impact drivers essentially work by combining the rotational motion with a hammering action to generate high torque.
If you have no idea what that means, picture it this way. Imagine while you are turning a screw, you started tapping it with a hammer in the direction of rotation. The screw would go in faster. That is essentially what an impact driver does.
When the motor alone is unable to provide torque to fasten or unfasten a screw, the spring-loaded hammering mechanism actuates.
The hammer mechanism lifts-up and rotates around and then is pushed down by the spring. It then hammer hits the output shaft transferring the rotational torque to it and this is repeated. This concussive blows to the spindle results in very high torque to the spindle.
Here is a video that explains the working principle of an impact driver. In the video, you can see that when the spring forces the hammer down it releases with an impact on to the output shaft. As a result, the energy stored in the spring is also transferred to the head along the linear axis.
An impact driver gives a blow to the screw around 50 times a second, which produces upwards of 5 times more torque than your average cordless drill.
So, if you are having issues getting a screw through tough material, then you may want to try swapping out a cordless drill for an impact driver. Note: Do not get confused impact driver with a hammer drill. In the latter, the hammering action is applied only at the rear end of the drill and not in the rotational direction.
You can see more details in the impact driver vs hammer drill article. Keep in mind that there is no option to change the torque on an impact driver.
The only control you have is on speed which you can vary using the control trigger. This is the reason why impact drivers are primarily used for loosening nuts, bolts, and screws.
