Product Overview

Optimize your CNC turning operations with our 60° Partial Profile laydown threading inserts. Designed for versatility, these threading inserts for lathe applications feature a non-topping geometry that cuts the thread groove without modifying the outer diameter (crest).

This smart design allows a single insert grade to machine a wide variety of pitches, significantly reducing tool inventory requirements. Whether you are running high-mix production or general maintenance, our inserts deliver precise thread forms and exceptional tool life.

Key Features & Benefits

  • The “Universal” Standard: The industry-standard 16er ag60 threading insert is the ultimate cost-saver, capable of handling pitches from 0.5mm to 3.0mm without changing the tool.
  • Comprehensive Range: We stock a complete line of sizes, from micro-boring 1/4″ I.C. up to robust 5/8″ I.C. inserts.
  • Left Hand Availability: Beyond standard right-hand tools, we offer specific left hand thread insert models (such as 11EL, 16EL, 22EL) to meet reverse threading requirements.
  • Precision Geometry: Our 16er threading inserts feature precision-ground cutting edges to ensure smooth chip flow and reduced cutting forces.

(Note: Internal threading models replace “ER” with “IR”, e.g., 16IR AG60. Left-hand models replace “ER” with “EL”, e.g., 16EL AG60.)

Machining Tips

  • Pre-Turning: Because these threading inserts do not top the crest, ensure the workpiece diameter is turned to the final size before threading.

  • Selection: For general workshop needs, the 16er ag60 threading insert is highly recommended due to its broad pitch coverage.
