Cordless impact drills are super versatile, which is the reason it is one of the first power tools that many people get for their homes or small businesses. Cordless impact drills are the best handheld tools for screwing down wood floors, installing backer boards, building porches or decks – practically any kind of job that involves driving a long bolt or screw into wooden surfaces. It basically does the job that would otherwise stall a cordless drill.
Impact drivers have probably never been as popular as they are right now. As well as the professional grade machines which have become virtually indispensable on the jobsite, we’ve also seen an increasing number of models aimed at the DIY market over the last few years.
What is an Impact Driver?
First of all, what does an impact driver do? As the name implies, they are designed primarily for driving screws, and they are fitted with ¼” hex bit holders for direct connection of screwdriver bits. However, to the casual observer the
benefits may not be immediately obvious. For instance, your average combi drill has an adjustable chuck, a choice of two or more gears, separate modes for drilling, hammer drilling and screw driving, and a clutch that enables precise
application of torque. An impact driver on the other hand seems significantly limited in comparison. It can only be used with ¼” hex shank accessories, and is typically bestowed with a far less impressive compliment of bells and
whistles – in fact many impact drivers don’t offer much more than a choice between either “forward” or “reverse”.
So why would you use an impact driver instead of a standard cordless drill? The adjustable clutch on a cordless drill would appear to make it much more suitable for driving screws, and indeed it can offer more “set and forget” control.
However, what impact drivers may lack in precision they make up for in speed and power and they can really come into their own when driving larger fasteners like decking screws and coach screws. If you compare the specifications of
drill drivers and impact drivers you will see that impact drivers are capable of far higher levels of torque.
The reason impact drivers can supply so much torque is that they have a type of rotational hammer mechanism which kicks in as soon as the tool encounters significant load conditions. This means they can work faster and harder than other
machines and have a serious edge when it comes to longer or thicker screws. The impact mechanism enables them to pound large fasteners straight into timber without having to drill pilot holes first, an undertaking which would quickly
stall a conventional drill driver. Likewise they are ideal for unscrewing tough, rusted or deeply set fasteners during demolition or renovation work.
That’s not to say they’re only for big jobs necessarily. Impact drivers are increasingly being designed with versatility in mind, and some of the most powerful models have settings which enable them to tackle more delicate applications
just as effectively. Most of the compact 10.8v and 12v machines are also more commonly used for driving small and medium screws rather than heavy duty fasteners which would be beyond their capabilities.
Impact drivers are also designed to be ergonomic, lightweight and user friendly. Even though many impact drivers are much more powerful than this, they can be used one handed as very little of the forces generated are transferred to the
user’s wrist. This means you don’t need the upper body strength of a silverback gorilla to control them and they can be used comfortably and safely even when undertaking heavy duty applications. They are also designed to be as compact
as possible, and the lack of a traditional drill chuck or clutch means they can be easily squeezed into tight workspaces.
