Description

The Carmex Thread Turning Internal Insert (Metric - Right Hand - 16IR1.0ISOK20) is a versatile tool designed for internal threading tasks. Designed for engineers, buyers, tradespeople, hobbyists, and workshop technicians, it delivers reliable performance across a broad range of thread standards.

Its laydown triangular geometry provides a stable cutting action, enabling you to tackle both basic and more demanding thread turning jobs with a single insert.

  • Broad thread standards compatibility: Handles the majority of thread standards available today, reducing the need to stock multiple inserts and simplifying planning.
  • Laydown triangular design for stability: Supports consistent cutting action, helping achieve smooth finishes and predictable results across a variety of materials.
  • Metric Right-Hand orientation: Sized specifically for metric threads with right-hand operation, ensuring straightforward selection and reliable performance on common internal threading tasks.

Together, these features translate into faster setup, fewer tool changes, and more consistent thread quality—so you can complete projects with confidence and keep production moving.
