The Carmex Carbide Tiny Tool is a compact threading tool designed for tiny internal threads in hard-to-reach bores. It features a 6 mm minimum diameter and 15 mm reach, making it ideal for tight spaces and small-part assemblies.

This MIR-threading tool uses a 60° partial-profile geometry and is compatible with 55° thread profiles, offering flexible performance across common standards. It supports a minimum bore diameter of 1.2 mm (0.05 in) and is available in two coated grades: BXC, a PVD TiN-coated option optimized for low cutting speeds and cleaner cuts, and BMK, a sub-micron grade with an advanced PVD triple coating for exceptional heat resistance and smooth cutting. It’s well-suited for a wide range of stainless steels (ISO P30-P50 / K25-K40) and general-purpose materials.

• Compact 6 mm shank with 15 mm reach: Provides access to tight bores and enables precise internal threading in small parts and assemblies.
• Coated for durability and smooth cutting: BXC TiN coating supports low-speed cutting for cleaner finishes, while BMK’s triple PVD coating delivers high heat resistance and consistently smooth cuts for longer tool life.
• Versatile threading geometry and material compatibility: MIR 60° partial-profile design with 55° profile compatibility, 1.2 mm minimum bore, and strong performance with stainless steels and other common materials.

This tool is designed to boost productivity by delivering reliable, consistent internal threads in challenging, space-constrained applications. Its dual coating options let you tailor performance to your material and speed requirements, helping reduce downtime, improve thread quality, and extend tool life across a range of projects from precision assemblies to repair work.
