A wood drill includes a clamping portion for connecting, for conjoint rotation, to a tool fitting of a portable power tool, and a head portion which is provided with a centering geometry. The clamping portion is formed at a first end, remote from a workpiece, and the head portion is formed at a second end, close to a workpiece, of the wood drill. The clamping portion is connected to the head portion via a shank portion. A maximum outside radius of the head portion is greater than a maximum outside radius of the shank portion. The head portion has at least one main lip with at least two stages for introducing a bore with a predefined inside radius into a workpiece. An outside radius of a main lip base is less than 60%, preferably less than 50%, of an outside radius of the head portion.

A grinding-means device, in particular a grinding-disc device or backup-pad device, for arranging at least one grinding means, in particular at least one grinding wheel, on a portable power tool, in particular a grinding machine, includes at least one receiving unit, in particular a grinding disc or backup pad, which is fixable in a thread-free manner on an output unit of the tool and on which at least one grinding means is arranged. The grinding-means device includes at least one securing unit formed separately from the receiving unit and configured to axially fix the receiving unit and/or the grinding means to the output unit of the tool in a tool-free manner, and/or at least to axially fix the grinding means to the receiving unit in a tool-free manner.

A tool storage device for storing application tools and/or assembly aids includes at least one plug-in member and at least one storage housing. The plug-in member is configured to retain application tools or assembly aids. The storage housing includes a receiving region for releasably fastening the plug-in member to the storage housing. The plug-in member has a first retaining end connected to the receiving region of the storage housing, and a second retaining end connected to the receiving region of the storage housing, in order to secure the plug-in member in a form-fitting manner with respect to at least a first direction. The plug-in member is connected to the storage housing such that the plug-in member is mounted, in particular clamped in place, firmly, in particular in a play-free manner, in at least a second direction on the storage housing.

An abrasive-means holding device for holding an abrasive means includes a holding body that is operable to rotate about a central axis. The holding body has a first side, a second side facing away from the first side, and a vacuuming opening that extends therethrough from the first side to the second side. The holding body also has a group of aspiration cavities that are arranged on the first side and that are fluidically connected to each other by at least one through-hole that connects the aspiration cavities. At least one aspiration cavity forms a vacuuming cavity that is directly fluidically connected to the vacuuming opening and that is configured to vacuum-off dust immediately out of an adjacent aspiration cavity and mediately out of a more distantly adjacent aspiration cavity. The aspiration cavities of the group are arranged in relation to each other along a linear course.

Toolbox

A holding device, in particular a grinding disc, for a grinding member includes at least one support member that has at least one material opening configured for transverse transport of grinding dust to one side facing the grinding member in a plane parallel to a grinding surface. The holding device further includes at least one securing layer configured to secure the grinding member on the at least one support member. When decoupled from the grinding member, the at least one material opening is at least substantially open on a side facing the grinding member and on a side facing away from the grinding member is substantially delimited by the support member.

A retaining body for a grinding structure, in particular a grinding wheel, includes a fixing layer with a fixing surface. The fixing surface has a fixing structure configured to fix a flexible grinding structure, and includes a support body with a support surface. The support surface supports a fixing layer retaining surface that lies opposite the fixing surface, and is connected to the retaining surface. The support body is air- and dust-permeable, and includes an air- and dust-permeable material. The fixing layer is configured such that the fixing surface is substantially air- and dust-permeable in a direction that runs substantially perpendicular to the fixing surface, and such that an air flow can pass from the fixing surface through the fixing layer in a substantially perpendicular manner relative to the fixing surface.

A hand-held machine tool comprises a driving motor that is mounted in a machine tool housing and is used to drive a tool, and a damping element accommodated in the machine tool housing. At least one damping element is arranged between the housing of the driving motor and the machine tool housing and forms a support element for mounting and supporting the driving motor in the machine tool housing.
