More Information
Summary:A setting tool driving fastening elements, comprising a holder for a fastening element; a drive-in element transferring a fastening element in the holder into a substrate along a setting axis by a setting energy Ekin of at least 30 J and at most 600 J; a drive for driving the drive-in element toward the fastening element along the setting axis, the drive comprising a capacitor, a rotor on the drive-in element; and, an excitation coil, which during discharge of the capacitor is flowed through by current and generates a magnetic field accelerating the drive-in element toward the fastening element, the drive-in element having a piston diameter dK and a piston mass mK, and wherein, for dK,⅔(a+b Ekinn)≤dK≤4/3(a+b Ekinn)where a=33 mm, b=6 mmJ−n and n=⅓ and/or, for MK,⅔(c+d Ekinn)≤mK≤5/3(c+d Ekinn)where c=20 g, d=30 gJ−n and n=⅓.
