![]() ![]() An impact driver does not drain the battery like a drill will under maximum strain. Thanks to modern innovation people have found ways to take a great product and improve it. The impact driver efficiently delivers nearly all of its energy to the drive head instead of your wrist – dramatically reducing fatigue and risk of injury. Reactionary torque is what twists up your wrist as you’re laboring to drive or drill on a traditional drill. ![]() If you’ve ever gotten your hand smashed against a stud when cutting a hole with a drill, you’ll clearly understand what this is. To put it another way, an impact driver has very little reactionary torque. This can make a significant difference on projects that involve driving a lot of screws, such as building a deck, installing tile backer board or screwing down sub-floor. ![]() All of this means less fatigue and reduced muscle strain. You also won’t have to exert as much force when driving screws because of an impact driver’s high rotational force. Since the drill bit and motor aren’t directly connected on an impact driver, you won’t have to experience the high-level torque while you work. Today’s light weight and powerful 20V Lithium driver produces a torque somewhere around 325 in-lbs, while an impact wrench has a torque somewhere around 1,600 in-lbs! A drill consumes a lot more power as it strains to deliver maximum torque and means you’re swapping batteries a lot more. #IMPACT DRILL DRIVERS#Impact drivers are fast and powerful, and without a clutch you could potentially ruin a job you’re working on if you’re not careful.įor each con an impact driver has it seems to have 100 pros. This helps to prevent screws being drilled too far or stripped. On a normal drill the clutch will disengage the bit when a certain amount of resistance is reached. Instead, impact drills use hex locking bits with a releasable sleeve on the tip of the drill, or an anvil, which accepts sockets. Unlike traditional cordless drills, impact drivers don’t have adjustable chucks meaning you will not be able to use your old round bits. There are a few drawbacks to the impact driver which help set its role and place in your toolbox. The impact has a much more significant effect. The impact wrench is like hitting the wall with speed from 10 yards back. A drill is like pulling your car up to the wall gently, and then pressing on the gas. (To keep the attorneys happy, we must say that this is for illustration purposes only and not recommended.) The same concept applies when thinking about a drill versus an impact wrench. But if you backed up 10 yards, slammed on the gas, and hit the wall with some speed and momentum you’d have a much better chance of making a significant impact on that wall. Depending on the strength of the wall it might move or it might not. If you inched up to the wall, touched it, and then applied the gas you’d be able to exert a certain amount of force on that wall. To better understand this concept imagine you are trying to knock down a brick wall with your car. ![]() How Does an Impact Driver Work?Īs the name suggests, impact wrenches slam the drive mechanism with a tremendous amount of force, then back up and slam it again. In fact, many NASCAR teams now use DeWalt battery impact wrenches on race day so they don’t have to worry about those pesky air hoses. Today, that same technology is available in battery tools. Remember the noise you hear in the auto garage or pit row at a car race? That vibrating, impact noise you hear is an air driven impact wrench. An impact tool gives you more driving power to drive screws, nuts, and bolts. Why is an impact driver an important addition to your tool box? ![]()
