![]() It’s worth mentioning that earlier designs were about all or nothing brute force. Hence, the force is better suited for driving bolts, screws, and other fasteners or removing them. However, the driver directs the force in the same direction as the rotation of the chuck. This process is similar to the hammer drill. The mechanism includes a heavy-duty spring that compresses at every half-turn and then releases a powerful force. ![]() But, it provides more rotational energy than the hammer drill. Although, it’s not recommended to use hammering action to drill plastic, wood, or metal.Īlso, it’s vital to deactivate the hammer mode before engaging in such applications with this tool.Īt first glance, the mechanism of the impact driver looks quite similar to the hammer drill. It even has a variation (SDS) that can drill into walls that are several feet thick. The hammer drill’s impact action is quite effective in drilling holes into brick, concrete, cinder block, and other similar tough materials. It’s just like chiseling and drilling combined in one tool. While the drill supplies rotational force, the gear-driven cam supplies force along the path of the drill bit in a linear striking motion. MechanismĪs I mentioned earlier, the hammer drill and the impact driver both deliver impact force differently.Īs the name implies, the hammer drill’s mechanism is like cooperation between a hammer and the drill. ![]() The impact driver only accepts bits with a 1/4” hexagonal shank. As a result, the impact driver can reach feats of over 4,000 impacts per minute. This impact generates a momentary amount of torque that surpasses that of the hammer drill. Once this happens, the hammer will rotate freely, enough to gather sufficient force to deliver a powerful blow to the anvil-when the coil gets released. But, when it reaches top speed, the hammer moves away from the anvil through the depressing movement of the coil. On the other hand, the impact driver has a lower supply of sustained torque. Plus, the adjustable chuck is compatible with bits up to 1/2” in diameter. The tool won’t only give you rotational power but a powerful force that also hammers in and out from the chuck with speeds that hit over 30,000 blows per minute. However, switching to hammer mode changes the tool’s mechanism. Like the regular drill drivers, hammer drills supply a sustained torque that continuously spins your bit at constant speeds. Note: this is just a preview of the mechanisms of these tools. Both tools operate with rotation, but how they use it is what differentiates them.Īlso, the type of torque and impact you get from these tools are different as well. You can spot the difference between both tools by comparing the drills in the following category: Designīefore we dive into the competition, let’s check out what makes up these tools. So, if you’re ready, let’s move on! Difference Between the Hammer Drill and Impact Driver I also added a few FAQs that will help you answer a few questions still bothering you about both tools. That’s why I created this article to show all the differences, features, pros, and cons between the Hammer Drill vs Impact Driver. ![]() There are more features and differences, which you can use to differentiate both tools. The impact driver on the other hand, rotates and makes an impacting motion as well. That is, the hammer drill pulsates and gives a knock on the head of the tool. If your answer is affirmative, then this article is for you.īut before moving ahead, it’s best you know this Ī hammer drill has a hammer function while the impact drill has an impact function.Īlso, the major difference between both drills is the force the tool head transfers. Or perhaps, you’re finding it hard to tell the difference between both tools at a glance? If you’re asking this question, it means you’re probably tired of worrying about which option is better every time-and not getting a headway-anytime you’ve a drilling task to handle. ![]()
