Abstract

The electrical hand tool unit, particularly angle grinder or cut-off grinder, has a drive housing (10), a motor housing part (6) and handle part. A counter-brake disc (26) is moved in release direction from a laminar actuating mechanism (36) extending in a level parallel to the level of the counter-brake disc against the spring pre-tensioning and the laminar actuating mechanism is tilted relative to the earlier level around a certain level.
