<p>The device has a tool shaft (13), which is frictionally clamped and unclamped in a sleeve section (4) made of electrically conductive material. A coil arrangement, completely or partly encloses a tool fitting (12). The coil arrangement consists of two coil-core parts (1,2) made of magnetically conductive and electrically non-conductive material. A coil, charged with alternating current, comprises the coil-core part. The coil is arranged not concentrically to a center axis (19) and does not loop it. Multiple coil-core parts consist of soft-magnetic e.g. soft-ferric, oxide-ceramic material.</p> |
