Abstract: A deburring tool (10) for deburring at least one through-hole (24) in a workpiece, the surface (38) of the through-hole (24) to be deburred located on the side away from the deburring tool (10), the tool comprising a main body (12) with a tool shaft (14) and a tool head (16), the tool shaft (14) having a clamping section (16) and the tool head (16) having a guide section (20) with a guide sleeve (22) extending along or parallel to an axis of rotation (36). The tool head (16) comprises at least one flexible fibre (26) with an abrasive surface (28), which is permanently or detachably attached in the guide sleeve (22), the fibre (26) having a free length (L1) and the guide sleeve (22) having a length (L2), the free length (L1) and/or the length (L2) corresponding to at least the depth (T) of the through-hole (24).

Abstract: The invention relates to an advancement guide unit (5) for ensuring the straight-line motion of a manually guided machine tool (I), particularly a portable drill, in the direction of advancement thereof and is substantially composed of a support element (12) for support on a work-piece to be treated and a carriage (30) guided displaceably on the support element (12) relative thereto in the direction of advancement for supporting and guiding the machine tool (1). According to the Invention, a damper (33) acting 48 in the direction of advancement is disposed between the support element (12) and the carriage (30), said damper damping the initial stroke of the carriage (30) toward the support element (12) over a predefined initial stroke distance (y). In a refinement, the damper (33) is disposed between the support element (12) and carriage (30) such that the damping of the initial stroke of the carriage (30) only commences after a primary, undamped initial stroke of the carriage (30).
