Cordless drill may be the most popular power tool of all time, but it seems to be losing ground surprisingly quickly to a relatively new tool called impact driver. That has got many, especially the do-it-yourselfers wondering what the fuss is all about.
So let us take a look at how an impact driver works and how it’s different from a cordless drill.
While the impact driver looks pretty similar to a cordless drill, it comes with one distinction that’s clearly noticeable, which is having a collet that allows inserting hex-shanked driver bits into it instead of a keyless chuck, a typical feature of a cordless drill.
An impact driver is also specially designed to be the best tool when it comes to working with screws – all types of them. It drives screws considerably faster and more effectively than all the other tools out there that are used for the job.
When some other tools are made to work with screws that are too large or too fat, they may get damaged in some way. The best impact driver, however, would usually get the job done just as quickly and effectively, which is perhaps what makes it the best tool for such tasks.
How it Works?
First things first, it basically works by delivering a lot of torque. However, it won’t produce the impact and torque as soon as it’s set on, as it takes it a bit to build up.
It also comes with impact gears for additional force. While the torque itself exerts a lot of force, when enough of it is produced, it also makes the gears start working. They tend produce a lot of extra power, which helps save a lot of time when working on time-consuming and complex tasks.
An impact driver also comes with a hammer that’s attached to its motor. The hammer helps take the power to a whole new level, with each fast, intense strike delivering a huge amount of torque. The superior force, generated in a surprisingly short period of time is what makes an impact driver the preferred tool for such a wide range of tasks.
Some Technical Details
Impact drivers come with a lot of speed, power and torque. An average impact driver, typically, may come with 2000 bpm (blows per minute) and about 2,500 RPMs (revolutions per minute). As far as the torque is concerned, it may be well around the 1,000 inch-pounds mark, which translates to some serious power and force.
