Without question, a cordless impact driver is the best tool invented for driving screws. I know many of us resort to our cordless drills when we have home chores and projects involving fasteners. If you have a large undertaking in front of you though, it would be worth a look and maybe you can even borrow one of these tools for a test. I know you will be pleasantly surprised with the results.
Have you ever struggled with sinking your screws to the right depth? How about stripping the heads and breaking the screws off in the hole? Maybe the task at hand just flat out required more power than your existing tool has to successfully complete your project.
18 Volt Cordless
Cordless drill/drivers and basic electric hand drills are just not designed to drive screws. Will they work? Yes, but there is a much better way.
An impact driver is designed to specifically take care of fasteners. They will hyper-drive your screws by using approximately 50 concussive blows-per-second while the bit is rotating. This will enable you to install your fasteners easier and more efficiently than ever before. It may take a few tries to establish the correct settings for every job, but once you get the feel for an impact driver your chore will be much less stressful. The dual action driving also takes the strain off of one's wrist.
Normally, an 18-volt driver/drill will give you approximately 500 inch pounds of torque more or less, depending on which manufacturer's tool you choose. A cordless 18v impact driver, because of the combination percussion rotating action, is able to supply upwards of 1300 inch pounds of torque. This is a staggering amount of power from a tool as lightweight and compact as today's models are. Most machine bolts and lag bolts are no match for these tools.
The allure of this type of tool does not stop here though. These impact drivers per size are as light and even in some cases lighter than the standard cordless drills. Many companies are now making chucks and impact driver quick conversion kits to easily enable hole drilling with these tools.
For the consummate professional and even the homeowner who takes on tough tasks, this type of tool should be in everyone's pouch. I'm sure if you will allow yourself the user experience you will agree. Most of the top manufacturer's cordless impact driver kits consist of a storage case, a charger and 2 Lithium-ion batteries. This battery technology is a must have from this point going forward if purchasing any type of cordless tool.
