The momentum of the rotating striker inside is what provides the rotation force, so even when you're driving something very tough it's quite easy to hold the tool.

WHEN TO USE AN IMPACT DRILL VS DRILL DRIVER DRIVERS

Finally, some impact drivers don't have a clutch, which means you need to be very careful if you're driving something that could be over-tightened or broken by the high torque.īesides the higher torque, impact drivers have another huge advantage in that you don't have to hold them tightly to provide the torque.

WHEN TO USE AN IMPACT DRILL VS DRILL DRIVER DRIVER

You can see this by holding the chuck with your hands while the driver is on you'll feel the pulsing of the strikes but chuck won't actually rotate. They're also not good for driving into something very soft–between the hammer strikes there's no torque applied and the bit can actually rotate backwards. This makes them good for heavy-duty jobs like driving long lag bolts (you can even take the lug nuts off your car wheels with most impact drivers), but the banging action makes them a little bit difficult to control. Impact drivers provide much higher torque but in rapid bursts–very much like a hammer provides bursts of linear force. They're good for work that requires care or precision, like drilling a hole or driving a a smaller screw. Drills and impact drivers are similar in that they're both rotating power tools and they have some overlap in usage, but they work differently and have different strengths.ĭrills apply a constant torque and tend to have good control across a range of speeds and clutch settings.
