Carmex Carbide Tiny Tool is a compact internal-threading solution designed for 55° partial-profile threads. Built from carbide for durability, it’s ideal for engineers, machinists, and hobbyists who need dependable performance in tight bores.

With a 4.1 mm minimum diameter and 15 mm reach, this tiny threading tool accesses confined cavities while delivering consistent thread form. It’s well-suited for stainless steels and a range of typical metalworking tasks where space is at a premium. The tool supports bore sizes down to 1.2 mm (0.05 in), enabling precise, repeatable threads in small components.

• 55° Partial-Profile Threading: Achieve accurate internal threads in small bores with a clean thread form for reliable assembly and minimal post-processing.
• PVD TiN BXC Grade for Stainless Steels: Low cutting speeds and enhanced wear resistance extend tool life when threading stainless steels (ISO P30-P50 / K25-K40), reducing downtime and rework.
• Ultra-Compact Size and Small-Bore Capability: 4.1 mm diameter with 15 mm reach lets you reach tight pockets and bores as small as 1.2 mm (0.05 in), shortening setup and boosting productivity.

This combination of precision, durability, and compact access makes the Carmex Tiny Tool a dependable choice for production runs and specialized projects alike. It helps you complete tight-tolerance threads faster, minimizes tool changes in cramped fixtures, and maintains consistent results across stainless steels and other compatible materials. By choosing this carbide threading tool, you gain a reliable, long-lasting solution that supports efficient workflows and better overall part quality.
