1/22/2024 0 Comments Hammer vs impact drillWhere more finesse or delicacy is required, it’s better to use the more precise control afforded by a combi drill. The impact driver is a fairly brutal power tool and is, for example, perhaps best used on site or in the home where it excels in effortlessly driving large screws. An added bonus is that the battery life is prolonged as impact drivers don’t drain additional power when the torque cuts in. Combined with the comparatively light weight, the use of an impact driver means that the stress in wrists, hands and forearms is also kept to a minimum. Impact drivers have no reactionary torque, which means that they can be safely operated with one hand as the way the torque is transferred within the tool means that the user doesn’t have to manage any external force (as with a conventional combi drill) which makes it easier to control. It’s easy to conclude that an impact driver can deliver up to three times as much torque! Benefits A comparable 18V combi drill is only able to deliver 50-60Nm of torque. Some impact drivers will provide over 150Nm of torque and even the smaller ones can supply approximately 100Nm, which results in an extremely powerful and functional tool. This varies from model to model, but in general terms, impact drivers have a electronically variable delivery of up to 3,000bpm (blows per minute) or 50 every second at 0- 2,500rpm, but it’s the torque which is really impressive. This means that the hammer action takes place inside the tool. On a hammer drill, the bit moves in and out, whereas on an impact driver, the bit stays put. Despite the hammer system, impact drivers aren’t hammer drills. These very swift, powerful blows supply the additional torque and it’s for this reason that the impact driver is so named. It’s at this point that the impacting mechanism starts to work, where the internal hammer attached to the motor rapidly starts to strike the anvil which is attached to the bit. The main difference is that the impacting mechanism of the impact driver isn’t activated until the torque required to continue driving is greater than the torque generated by the rotational power of the motor itself. The impact driver works in a radically different way to the combi though essentially it’s a powerful, fast, cordless drill.
