Carmex Carbide Tiny Tool - Threading - MIL - 55° Partial - BXC Grade - 4.1mm Minimum Diameter x 15mm Reach (Left Hand)

The Carmex Carbide Tiny Tool is a compact threading solution designed for small bores and tight work envelopes. Built for engineers, machinists, and hobbyists alike, it enables precise 55° partial-thread profiles with a left-hand configuration, a 4.1 mm minimum diameter, and a 15 mm reach for hard-to-access features.

This versatile tool is optimized for threading in narrow spaces, supporting a minimum bore diameter of 1.2 mm (0.05 in). It combines a robust carbide body with a coated tip to deliver reliable performance across a wide range of materials, including stainless steels, while maintaining smooth cutting and consistent thread quality.

• 55° partial-profile threading geometry: Delivers accurate, consistent thread form in restricted bore spaces, reducing rework and improving surface finish.
• Coated carbide for wear resistance: A durable coating enhances longevity and smooth cutting at low speeds, helping maintain performance across stainless steels and other common alloys.
• Compact left-hand design with 4.1 mm diameter and 15 mm reach: Fits into tight bores and reaches the depth needed for precise, short-thread features without repositioning the workpiece.

This tool supports reliable, repeatable small-diameter threading, helping you improve workflow, reduce setup time, and achieve consistent results across challenging bore geometries. Its compact profile and durable coating are built to withstand demanding shop environments, delivering dependable performance when every micron counts.
