Abstract: The present invention relates to a variable camshaft adjuster (VVT) for an internal combustion engine with a VVT component, preferably a locking disc, composed of material produced from powder metal with a locking bore, which extends from a first surface of the VVT component, preferably the locking disc, into this, wherein a locking bolt of a variable valve control engages into the locking bore and the locking bore has a connected oil duct which also extends from the first surface into the VVT component and discharges radially into the locking bore, wherein a base of the locking bore has an elevation, preferably in the form of an elevated shoulder which serves as a bearing surface of the locking bolt and the oil duct has a depth which is smaller than that of the locking bore. A VVT component, in particular a locking disc as well as a method for producing the locking disc or the camshaft adjuster are furthermore claimed.
