A countersinking tool, comprising a tool shank and a tool head with multiple deburring or countersinking edges and an insertion pin. In some embodiments, the insertion pin features at least one reaming edge, on a radially outer side and extends over less than 33% of the overall length of the insertion pin, wherein the reaming edge can be inserted into an unfinished bore with a diameter, smaller than a nominal diameter of the bore, in a cutting fashion, wherein the reaming edge acts as a drill bit and is arranged on the insertion pin at a radius that corresponds to the radius of a nominal diameter of the bore, and wherein the insertion pin has the nominal diameter of the bore and can be guided in the bore without play. Also, a tool arrangement with a countersinking tool and to a method for producing a countersunk and/or deburred bore.
