SpeedE Industrial Cordless Screwdriver, 5 Piece - 

Anyone who spends much of their day fastening screws knows how much time it takes and the considerable strain it causes to wrists in the long run. With the world's first e-screwdriver speedE® by Wiha, such problems become a thing of the past once and for all. The speedE® allows you to fasten screws twice as fast as with a conventional screwdriver and still have full control over the tightening force thanks to the material protection function. On reaching 0.4 Nm, the power-assisted fastening switches off automatically to protect the material and users can finish tightening screws carefully by hand using up to a maximum of 8 Nm. Thanks to its electric ratchet function and award-winning SoftFinish® handle shape, the speedE® noticeably reduces strain on joints, tendons and muscles. It is recommended by German doctors and therapists at German Campaign for Healthier Backs for this very reason.
