Product Uses
1.The Micro threading bar features specialized edge honing that resists chipping on thread crests and flanks, maintaining intact tooth geometry under interrupted cutting conditions.
2.The Internal threading tool accepts full-profile inserts for metric, UN, and custom thread forms, enabling rapid thread type changeover without removing the toolholder.
