Product Overview
Achieve mass-production quality with our ISO Metric Full Profile laydown threading inserts. Unlike partial profile tools, these carbide threading inserts are engineered to cut the complete thread shape, including the crest (major diameter). This “Topping” action creates a precise, burr-free profile that eliminates the need for secondary polishing operations.
Designed for stability and precision, these threading inserts for lathe holders are the preferred choice for CNC environments where thread form accuracy and surface finish are critical.
Key Features & Benefits
- The 16ER Standard: Our 16er threading inserts are the workhorse of the industry, compatible with all standard ISO tool holders.
- Inventory Depth: We supply a vast range of pitches from 0.5mm to 6.0mm, ensuring you have the right tool for every ISO metric job.
- Directional Options: To support complex turning operations, we offer standard right-hand models and specific left hand thread insert (EL) versions.
- Productivity Boost: For high-volume runs, check out our Multi-Tooth (2M/3M) models (e.g., 16ER1.5ISO2M) which reduce the number of passes required.
