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.
CORDED HAMMER DRILL IMPACT DRIVER COMBO 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. Summary: Cordless Drill vs Impact DriverĪn impact driver is used to drive fasteners and screws into a dense material.Differences between Impact Driver and Drill/Driver.
