For very hard steels, TOOLOX and HARDOX materials we recommend deviating from the DIN data (see table) by drilling the tapping ⌀ 0.05 to 0.3 mm larger. For use only with a length compensation chuck − even on machines with synchronised spindle drives.
Application for type of drilling
up to 1.5×D for blind holes and through holes
Type of threading tool
Machine tap for dynamic machining
Here application data as well as tool and material information are made available with which you can optimally plan your production process.
