However, to continue driving the screw and overcome this resistance, impact drivers must deliver extra torque. When driving screws, impact drivers tend to encounter resistance which is expected to occur with every drilling tool. The impact functions create a high level of torque when driving in screws by delivering strong rotational bursts of super force inside this power tool. Impact drivers called that mostly because of the impact function it possesses. Difference Between Impact Driver and Hammer Drill Functions Did I also mention the noise this tool gives off while in use? Well, that noise is a result of the hammering action, and it occurs many times depending on how rapidly you are driving in the screw.įor detail and updated information read what is a hammer drill, Impact driver, and hammer drill differences with the comparison charts. These hammering actions are just not downwards but also sideways, and this makes it an easy task when driving in screws into tough materials.Īnother benefit of this movement is that it prevents the screw from slipping off and potentially ruining the screw. Impact drivers make use of the rotational motion which hammer drills use, but impact drivers mix in a hammering action as you are driving in a screw. Still talking about the difference between an impact driver and a hammer drill I will talk more about the impact driver.Īn impact driver is a super tool for driving in screws. While an impact driver’s primary use is to drive in fasteners like screws, it can alternatively be used to drill holes. A hammer drill commonly used to drill into concrete-like hard surfaces, although few hammer drills do possess a feature that turns them into a regular drill or driver. Purpose can differentiate the two power tools. However, the most notable differences between the impact driver and hammer drill lie in the cost, weight, appearance, and method of operation. They are not mainly at fault here because the two can use in place of the other in some cases. In the world today, those who use power tools are mostly confused about the difference between an impact driver and a hammer drill.
