Description
Version:
Especially sturdy design.
For use in heavy duty applications.
For use in heavy duty applications.
Application:
For Whitworth parallel pipe threads DIN-ISO 228/1 (threads that do not form a seal within the connection).
Recommendation:
For very hard steels, TOOLOX and HARDOX materials we recommend deviating from the DIN data (see table) by drilling the tapping hole ⌀ 0.05 to 0.3mm larger. For use only with a length compensation chuck − even on machines with synchronised spindle drives.
