How do impact drivers work?

How do impact drivers work? Roger visits Triton and finds out how impact drivers manage to punch way above their weight.

“Impact drivers seem to be the future – when you’re out on site you hear them everywhere.

“Triton have got their 20V model out which as Steve Hewson, Triton’s product manager explains is particularly aimed at the trade buyer who’s putting in fastenings all day.

“Compared to drills impact drivers provide a lot more torque for their size.”

Steve explains how the impact driver’s sprung weight mechanism helps the impact drivers achieve this.
