Buy an impact driver and save your wrist. This can cause problems to your wrist especially if you are doing a large project that requires you to use lots of fasteners. With a drill/driver, you will have to apply pressure on to the screw to drive it through hardwood or other tough material. Where an impact driver truly shines is in its ability to drive long screws with ease. Just in general, there is no reason to use an impact driver to drill holes into a soft material when a cordless drill does the same job so much better. Unlike regular drill bits, hexagonal shank drill bits may not be available in all sizes. You can also drill holes with an impact drill/driver however, you need drill bits with hex shanks. This makes cordless drill an excellent general purpose power tool for home improvement, woodworking, metalworking, handyman jobs etc.Īn impact drill is mainly to undo or to drive in screws and fasteners. You can also mount polishing wheels and small mounted grinding wheels to perform various tasks. As I said earlier, a cordless drill can be used to drill holes into various kinds of material and to drive in screws with accurate torque control. In terms of versatility, the cordless drill wins hands down. The first major difference is the range of jobs that each tool can be used for. Rotate the outer ring for different clutch setting to precisely control the output torque.ĭrilling and driving screws in hard material. The cordless drills are designed with self-centering chucks and clutch. Secondly, and more importantly, they are used to drill holes into wood, drywall, plastic, and other soft materials. Firstly, they are used to drive screws and fasteners into the material. I think most, if not all of us, know what a cordless drill is. To learn more about the differences refer impact drill vs hammer drill guide. A hammer drill offers high axial force and is the ideal tool for drilling masonry. However, do not get confused between a hammer drill and an impact drill/driver. Since the hammer mechanism delivers high rotational force (torque), impact drills can be used to drill tough materials like hardwood and metal. That’s where the term impact drill comes from. Impact driver is the most commonly used name since the primary purpose of this tool is to driver fasteners.Īn impact driver can also be used for drilling using the external shank drill bits. You can see a detailed explanation of the working principle of impact driver here.ĭo not get confused between these two terms. This is done by the spring that gets compressed during the rotation and pushes the hammer back on to the anvil with an impact. #HAMMER DRILL VS IMPACT DRILL VS DRILL DRIVERS#The internal impact mechanism provides high torque to the impact drivers which the regular power drills cannot achieve.Īlthough the internal hammer primarily delivers impacts in the rotational direction, it also delivers blows in the axial direction. However, where the impact drill sets itself apart is by also introducing hammering action into the mix. Both use rotational power to drive things into the material. In this sense, an impact drill is similar to a regular cordless drill. When you use an impact drill on a screw, it rotates and drives the screw inwards. An impact drill combines two kinds of power, rotational power, and concussive power. While this is true, an impact driver works differently. Now, you may note that that is partly what cordless drills are meant to do as well.
