In this demonstration Youtuber Nick Moore opened up a impact driver and then put to use driving a bolt, all while filming it at 1200 frames per second. You can see how each 1/2 turn of the drill rotates an internal hammer that compresses a spring. When that spring is released, the energy drives the hammer down while simultaneously twisting it. The tat-tat-tat sound you hear is the motion over and over again. This concussive force is what separates an impact driver from a standard drill/driver which requires a user to apply downward force.

We're big on impact drivers and have shown how to use them, how they compare to drill/drivers, and ginned up a tool test for finding the one that suits your needs. If you've ever been curious to how the mechanism inside really works, the video below has got you covered. here

The recently released Stealth Force impact driver from RIDGID has done away with the loud tapping sound by combining the hammer mechanism with an oil chamber. We'd love to see a cutaway view of how that one works.

Before we ever started crunching the data from our test results, Tom Gaige called me up. He wanted to tell me how impressed he was with the Makita XDT16 impact driver. It’s the most compact (by 1 mm) and the second lightest on our scales. At the same time, it held its speed. It also produced more measurable torque than we found in our other impact driver reviews, some touting hundreds of more inch-pounds in their specs.

In our 12V testing, it took another M12 Fuel product to finally knock the M12 Fuel 2553 off the top of our charts. The Milwaukee M12 Fuel Surge did it with the highest torque numbers of all our 12V impact driver reviews. It also had significantly less noise than any other impact driver we’ve tested.

Cordless drills are popular and versatile, but impact drivers can drive screws at astonishing speeds. We'll help you decide which is the best for your shop.

Here’s what you need to know to select the right drill.

[nacarino]

Chuck size: Cordless drills are equipped with two different size chucks, 3/8 inch or ½ inch. Choose a product with a larger chuck diameter if you expect to routinely drill larger diameter holes.

Grasp the tool firmly in your left hand (if you're right-handed). more

Strike the top of the impact driver with a hammer. Wear heavy gloves to minimize injury if you accidentally hit your hand with the hammer. [links]

Hand impact drivers are fantastically simple tools. The first time you see one, you will wonder how it could possibly work---but work they do, and amazingly well. There's no other tool that handles the job these tools were intended for. There's a great deal of control with a hand impact driver, unlike a power impact tool. If you can hold the tool and swing a hammer, you can use this very affordable and indispensable tool.

Install the bit adapter and bit or the appropriate socket on the tool.

The impact wrench has a compact design that is made of quality metal and plastic parts sometimes covered with rubber. For example, the handle is ergonomic and covered with rubber for safer holding. it has a narrow head made of metal to fit into the narrow space and to be prone to damages. All in all, it is very lightweight and can be used in the automotive industry. here
