Typical Applications
  • Miniature internal thread tapping (M1.6×0.35) in CNC precision centers
  • Electronics, medical devices, watches, and small molds
  • Through-hole & shallow blind-hole threading
  • Mass production of micro-components requiring YH1 precision
  • Dry or minimal coolant for small-diameter stability
  • Finishing operations for smooth thread surface
Why Choose YG-1 M1.6×0.35 YH1SF?
  • YH1 precision: Tight tolerance for perfect fit in miniature assemblies
  • HSS-E grade: Withstands high temperatures in small-diameter cutting
  • Special flute (SF): Optimized chip geometry prevents clogging in tiny holes
  • YG-1 quality: Korean manufacturing, consistent performance in mass production
  • Miniature design: Ideal for hard-to-reach, small-part threading
