The Carmex Carbide Tiny Tool is a compact threading solution designed for internal threads in small bores, with a MIR 60° partial-profile that suits tight spaces. This tool is ideal for engineers, machinists, and hobbyists who need precise, repeatable threads in challenging interiors; it supports 55° profiles and, with a minimum bore diameter of 1.2 mm (0.05 in) and a 5 mm reach, helps you access recessed features quickly and reliably.

• Coating options for versatile threading performance: BXC TiN coating reduces friction for steady cutting at low speeds—great for stainless steels—while BMK’s sub-micron, triple coating delivers exceptional heat resistance and smooth cutting across a broad material range.
• Small-bore threading capability with 60° MIR partial profile: Specifically designed for internal threads in tiny bores starting at 1.2 mm, the 60° MIR partial profile ensures clean, accurate threads and reliable engagement with 55° profiles.
• Rugged carbide construction with compact reach: Precision-grade carbide provides long tool life and dependable performance, and the 5 mm reach enables access to tight or recessed features, reducing tool changes and downtime.

With this tool, you can complete tight internal threads faster and with greater consistency, expanding the range of parts you can finish in-house. The dual coating options let you tailor performance—BXC for efficient threading in stainless steels and BMK for high-heat, high-demand jobs—without swapping tools. The compact 5 mm reach and robust carbide design keep setups simple and reliable, helping you meet tight tolerances and improve overall workflow.
