When you use a cordless impact wrench, you can continue inserting screws all day long, and at the end of the day, you will also feel the difference as it does not tire you at all. If there is no reactive twisting on your hand or wrist, it will do little work by inserting the screws with the cordless impact wrench. All the effort is made by the tool and its powerful punching action as it gets up to three or four times the torque as compared to a conventional screwdriver.
Now you just forget to drill pilot holes in 2×4 boards or crossbeams, as you simply insert these screws directly as it is a great way to save time. The available torque is up to 1,500 inches per foot on higher voltage which will help insert the lag screws very easily with the help of a cordless impact wrench.
An adaptation of the cordless impact wrench has a square wrench of 3/8 or 1/2 inch. The electric cordless screwdrivers are generally lighter than the air tool, but the biggest benefit is that they do not have a heavy hose ever cluttering. These square wrench tools have impressive torques of up to 700 pounds per foot on a ½-inch 20V screwdriver.
The cordless impact wrench can also be used as a drill using hex key drills, as the high speed of the screwdriver can drill a small hole very fast. For the larger holes, the screwdriver can be changed to impact mode to quickly insert a large drill bit or hole saw.
Selection of the Drill Bit
All cordless impact wrenches use hex wrenches to quickly insert them into the tool, so you will need a set of insertion bits that may include drill bits and screwdrivers, square insertion converters of 3/8 or 1/2 inch and maybe some other specialized drills.
The cordless impact wrench is a very versatile tool as it has a wide variety of the drills which will allow you to explore all the opportunities to take advantage of the speed and the ease of use of the tool.
The insertion drills are subject to the incredible stress and cheap bits simply do not work, especially when Phillips-head screws are inserted. In fact, if you can, think of the tool bit when you choose your screws. You will get much better performance when you use a six-headed, six-point screw head or other special patented design that resists the drill sweep.
