3/31/2023 0 Comments Impact driver vs drill![]() ![]() ![]() But if your main need is for driving screws (laying down a deck?) or other fasteners, then an impact driver wins hands down. If the focus is on pure drilling of holes with the occasional need for driving screws, a drill will be just right for you. An 18v impact driver can seat long lags with little bogging down, over and over, while a cordless drill will start to slow down and eat up the battery life with even one. While you can get socket and nut driver attachments for both tools, this one is no contest. They are lighter, they have more torque, the impact action prevents cam-out from stripping the screw heads, and the higher torque means no problem working with long screws. With soft, brass screws, you may even prefer the drill for better control – the impact action might start up just at the wrong moment and shear off your screw head! Additionally, if you are concerned about noise for whatever reason, a drill would be the better choice.īut, for general screw-driving tasks, the impact driver is almost always the best pick – for a number of reasons. With smaller screws, a drill will work fine. On an impact driver, however, the high torque and the hammering action will power through with no trouble. When hogging out large holes with a 1″ spade bit, for example, the battery on a cordless drill will wear down quickly. However, in certain drilling tasks the impact driver is better. Additionally, hex-shank drill bits are harder to find and more expensive than the regular round-shaft drill bits. With the impact driver it may be harder to line up and keep precise holes if you are working with fine construction. Better control is one of the main reasons to use a drill. Since the energy is built up over time and then delivered in strong impacts, the reverse torque on the users hand and wrist is greatly reduced.Īs you might expect, a drill is usually the better choice for drilling holes.This repeats thousands of times a minute, and adds up to a hefty bit of torque. ![]() The spinning motor whirls the hammers up to speed, at which point they smack the anvil and transfer all their energy in a sudden impulse.The torque comes from additional components – called the hammer and anvil – that kick in once the extra power is needed. The motor is much smaller, however, and doesn’t produce as much torque as the drill.Powered impact drivers also have an electric motor to produce an initial rotation, like a drill.This feature can prevent someone from driving a screw too far into the material and splitting it, as well as help prevent stripping of the screw head. This stops the chuck from spinning while letting the motor spin free with a click-click-click. When the torque required to turn the bit reaches the setting’s threshold, the clutch disengages the drive shaft from the motor. Some drills sport an adjustable chuck with various settings.Many also have a speed setting allowing you to adjust the top speed/torque depending on the needs. The triggers are usually variable-speed, meaning that the more you squeeze, the faster the drilling.By squeezing the trigger switch, the motor turns on and begins spinning. In this article we are going to explore those situations and see which – if any – is more versatile.įirst let’s get an idea of what makes the drill and impact driver different from a technical standpoint.Ī standard power drill rotates the bit using a conceptually simple electric motor. Depending on the task at hand, one of the two may be much more effective at getting the work done. On the job site, or even around the home, lugging both around can get cumbersome. In fact, there is so much overlap some people often wonder if it’s worth having both tools. That being said, there is also a lot of overlap in their usage. Cordless drills and cordless impact drivers each have distinct strengths.
