Description

The Carmex Carbide Tiny Tools - Small Threading Trapez Tool (MIL) is a precision cutting tool designed for small threading applications. This tool features a trapezoidal thread design, which is ideal for creating threads with high accuracy and precision.

Crafted from premium-grade carbide, it offers exceptional durability, strength, and wear resistance. Its compact size makes it perfect for threading small parts, and with a 11.5mm minimum diameter and 45mm reach (left-hand), it excels at threading in tight spaces on a wide range of machines.

  • Tiny-threading precision with trapezoidal geometry: The trapezoidal thread form delivers accurate, repeatable threads on small parts even in tight spaces, helping you meet tight tolerances and reduce rework.
  • Premium carbide for durability and wear resistance: BMK-grade carbide provides long tool life and reliable performance against demanding materials, lowering downtime and replacement costs.
  • Wide machine compatibility with left-hand threading: Designed to fit a broad range of milling and threading setups and supports left-handed threads for versatile applications across projects.

This tool enables faster, more consistent small-threading results, improving workflow efficiency and part precision. Its robust carbide construction and thoughtfully designed geometry give you confidence across machining tasks, from delicate prototypes to production runs, while the broad machine compatibility minimizes setup time and driver changes.
