Production of internal threads

The core hole is predrilled with a core hole twist drill. Select the drill diameter according to the table. Important: For blind holes, the core hole must be predrilled deeper than the desired thread by the lead length. We recommend that you lower the core hole to the thread diameter. Fasten the tap in the adjustable tap wrench or in the tool holder for the smaller dimensions. Make sure that the screw thread of the arm of the adjustable tap is tightened firmly Place the tap perpendicular to the hole. Under light pressure, the tap is turned clockwise into the hole using the tap wrench. After half a turn, the chip must be broken by turning it back.
