How Do Cordless Impact Drivers And Cordless Drills Compare

Steve Jones writes about Cordless Impact Drivers for CordlessDrillWorld.com

This effect is similar to that of a hammer tapping on a wrench to loosen a stubborn nut or bolt – any it delivers much more torque.

Are cordless impact drivers powerful

In action they will function like a cordless drill until greater torque is needed, at this point the spring and the cam mechanism mentioned above comes into play, adding up to 2500 blows per minute to the output of torque, this effectively can triple the torque output available.

However the cordless impact driver’s torque is converted directly onto the screwdriver head, this allows you to easily hold the drill with one hand without noticing any significant amount of reactionary torque – this feature is great if you use a cordless tool all day as it eliminates arm strain and vastly reduces wrist problems.

Other Features of Impact Drivers

Cordless impact drivers are very compact and are generally half the size of a cordless drill, this makes them very useful for getting into confined spaces such as overhead ducting and Cabinet assembly jobs, they also generally weigh less as well, a cordless impact driver normally weighs around three to 4 pounds compared to 6 to 9 pounds of a cordless drill.

Impact drivers do make more noise than a conventional drill/driver as the cam mechanism makes a chattering type of sound when it is activated, the battery life of a cordless impact driver is generally greater than a cordless drill as the cam action makes bigger the total torque without increasing the battery drain.

Who Should Use A Cordless Impact Driver??

Tradesman usually use cordless impact drivers to drive heavy duty fittings into concrete and other masonry.

All of these capabilities make impact drivers an valuable power tool to electricians, Cabinet installers, roofing contractors and deck builders and any other tradesmen who needs a powerful and compact method of driving screws and bolts.

A good question, we would say if you are a contractor who needs a large amount of driving torque to drive fittings into robust materials then the cordless impact driver is for you, if you are a DIY user who needs a all purpose cordless tool then go for a cordless drill/driver of around 12volts or above, they have lots of torque and will drive heavy screws into most materials with ease.
