TECHNICAL INFORMATIONSinlge edged insertsWhen entering through a bore off centre and withoutrotating it is possible to generate back chamfers andflats with inserts having a larger cutting diameter thanthe bore diameter. Single edged cutters have no run outtolerance.GThread millingWith HORN thread milling inserts the thread profile isgenerated in one full cut to the profile depth of the thread.This produces threads with minimal taper especially inhigh alloyed steels.In blind holes it is recommended to mill from the bottomto the top. Otherwise there is the risk of damaging thetool because of milling into chips at the bottom of theblind hole.A general recommendation for thread milling:The milling cutter diameter should not exceed 70% of theminor diameter of the thread. Otherwise recutting of theprofile occurs which could bring the whole thread out oftolerance.G6
