Description

Product Information

16ER External Indexable Carbide Threading Insert The 16ER series is an industry-standard, laydown-style threading insert designed for high-precision external thread-turning operations on lathes. Engineered for efficiency, these inserts feature three cutting edges, offering an economical solution for high-volume threading tasks. They are widely used in sectors requiring high-accuracy joints, such as the automotive, aerospace, and general manufacturing industries.

  • Optimized Performance: Features excellent anti-built-up edge (BUE) properties and superior chipping resistance, making it ideal for both semi-finishing and finishing of various steel parts.

  • Versatile Design: Available in both Full Profile (which cuts the complete thread including the crest) and Partial Profile (V-profile) geometries that can handle a range of pitches.

  • Advanced Coatings: Typically finished with high-performance PVD coatings like TiAlN or Nano-AlTiNSi(N) to provide exceptional thermal stability and long-lasting durability during high-speed cutting.

  • Precision Threading: Designed to eliminate the need for secondary grinding operations while delivering smooth chip removal and flawless surface finishes on stainless steel and alloys.
