Description

The Carmex Carbide Tiny Tool is a precision threading cutter designed for small-diameter applications. Its trapezoidal thread form (MIL) delivers accurate thread profiles on miniature components, helping you achieve tight tolerances and consistent results in challenging small-thread work.

Made from premium K20 carbide, it offers durability and reliable edge retention for repeated threading tasks. It features an 11 mm minimum diameter and a 55 mm reach, and is designed for left-hand threading. It is compatible with a wide range of machines and systems, making it a versatile choice for varied shop setups.

  • Precision trapezoidal threading for small parts: Achieves accurate thread profiles on miniature components, reducing rework and ensuring a proper fit.
  • Premium K20 carbide for long tool life: Provides wear resistance and edge retention to extend tool life across demanding threading tasks.
  • Compact geometry with broad machine compatibility: 11 mm minimum diameter and 55 mm reach enable access in tight spaces, with left-hand threading and wide machine compatibility for flexible use.

By combining precise trapezoidal threading with a durable carbide body and a compact reach, this tool supports faster setup, fewer tool changes, and consistent thread quality across batches. Its broad machine compatibility simplifies purchasing and inventory, so you can rely on one tool for multiple applications. In daily use, you’ll experience cleaner finishes, tighter tolerances, and more predictable results—helping your workflow stay on schedule and your parts meet spec.
