Claim 7:
8. A tool system comprising:
a hand-held power tool comprising:
a machine housing; and
a supporting device for guiding the hand-held power tool on a workpiece, the supporting device including a carrier element, in which the machine housing is at least in part accommodated and fastened, the carrier element including an end flange facing away from the machine housing, the end flange defining a groove; and

a base plate fastened to the end flange, the base plate configured to bear against a workpiece and to enable an insert tool to pass through the base plate; and
an edge guide configured for guiding the hand-held power tool along an edge of the workpiece and configured to be fastened to the end flange, the edge guide comprising a holding arm having a fastening portion configured to be at least in part accommodated in a positive-locking manner in the groove, the fastening portion defining at least one through bore for an associated threaded screw that is configured to fasten the fastening portion to the end flange,
wherein the at least one through bore merges into a longitudinal slot which is open toward a holding arm end, and
wherein the longitudinal slot has a V-shaped chamfer and the at least one through bore has a countersink;
wherein the associated threaded screw is engaged in a threaded bore extending into the end flange from a bottom of the groove and has an axial length; the axial length and the head of the associated threaded screw are configured such that with the associated threaded screw fully loosened, the head of the at least one threaded screw abuts the base plate with the associated threaded screw in threaded engagement with the threaded bore;
wherein the base plate defines a through bore configured for a tool to pass through for operating the associated threaded screw; and a diameter of the base plate through bore is smaller than a head diameter of the associated screw.
