The core hole is drilled with a twist drill. You can find the required Twistdrill diameter in the table. Important: The core hole for blind holes must be drilled to the tap point deeper than the required thread. We recommend to lower the core hole to the thread diameter. Attach the tap into adjustable tap wrench or in the toolholder with ratchet for lower sizes. Pay attention that the screw thread of the arm of the adjustable tap wrench is fixed properly. Apply the tap vertically to the drilling. Rotate the mounted tap clockwise into the drilling. After each half-turn the chip must be broken by rotating back again.
For cutting external threads according to the ISO Standards of metric coarse threads M1 to M68 and metric fine threads M1 to M56 preslotted (Form B) round dies are used.
