With the hammer drill, the spinning action is combined with, you guessed it, a hammering action. Without getting into some pretty intense physics/engineering type stuff (which is over our heads anyways), we’ll talk briefly about the differences in action between the hammer drill and the impact driver.Ī standard electric drill simply spins the drill or driver around – there’s no additional action. This doesn’t happen with an impact driver.Īs far as differences in action, we’ll discuss those in the next section below. You may have run into problems from time to time with your standard drill (probably when trying to push it beyond its limits) where the chuck has lost its grip on the drill/driver bit, or even had it fall out entirely. Impact drivers, on the other hand, have a locking collet that only accepts hex-shanked bits. Hammer drills are much more universal in this regard, as their 3-jaw chuck will accept both round and hex bits. One of the major differences between an impact driver and a hammer drill is the types of bits they’ll accept. Hammer drill and Impact driver: Key differences Thus, both the hammer drill and impact driver really do serve legitimate purposes – if you do end up adding one or both to your power tool arsenal, you’ll wonder how you ever managed to get by with just your standard power drill. Thousands of people a day probably get by just using a standard drill for these purposes, but we’ve all run into the problems faced when trying to do so: broken/ burnt out drill bits, jammed screws, and stripped screw heads. Impact Driver ()Īn impact driver’s main purpose is driving big, long screws into tough material (studs, concrete/masonry, drywall, etc.) They’re simply more powerful than your standard cordless drill/driver. Video can’t be loaded because JavaScript is disabled: Drill vs. Here’s a good little video really showcasing the advantages and functionality of both the hammer drill and the impact driver. Ok, very generally speaking, a hammer drill serves one main purpose: drilling holes through masonry (concrete/drywall).
