School of Instruments: Powerful Impact Driver
The short steel impact driver is often overlooked compared to its ubiquitous counterpart, the drill. But once you strike, you will not come back.
An impact screwdriver is the ideal fastener. These cordless power tools are used to tighten or loosen bolts and screws using strong rotational and downward forces. Imagine a hammer hitting the back of your screw quickly and another hammer hitting a pair ofpliers attached to your chisel. The video below shows a sectional view of how the tool works.
The extra power increases driving torque and pressure and relieves stress on the arm and wrist. Thanks to this mechanic, they are less likely to open screws and are very accurate to use.
The impact screwdriver has a ¼ ”hex quick release socket that allows for quick bit changes like a standard drill. If you only have standard drills, you will need to convert them to hex shaft bits that will work with your drill.
This DeWalt is the # 1 selling on Amazon and is priced at $ 229. The best shock driver like this one includes a brushless motor (for more power and longer run time), three speeds for more precision, and two 20V batteries.
You can find single speed models with brushed motors like the Black + Decker for less money, as well as compact shock drivers that are powered by 12V battery platforms like the Bosch shown above. Both are great options for your day to day chores.
Get a shock driver from friends to use on your next home improvement project and it’s unlikely you’ll ever get it back.
