Carmex Carbide Tiny Tool - Threading - MIR - 60° Partial - BMK Grade - 4.1mm Minimum Diameter x 17mm Reach

The Carmex Carbide Tiny Tool is a compact, partial-profile threading bar designed for precise threading in tight bores and small components. It's ideal for engineers, machinists, hobbyists, and tradespeople who need reliable, high-quality threads in stainless steels and a wide range of materials. The tool’s partial-profile geometry is compatible with 55° threading profiles, and its compact form helps you access cramped features with confidence.

Its specifications include a 4.1 mm minimum diameter and 17 mm reach, plus the ability to work in bores as small as 1.2 mm (0.05 in). This combination makes it a versatile choice for micro-threading tasks where larger tools simply can’t fit.

• Partial-profile geometry for tight bores: Access small internal features and maintain accurate thread form in confined spaces with a 4.1 mm minimum tool diameter and 17 mm reach, suitable for bores down to 1.2 mm (0.05 in).
• Two coating grades for versatility: BXC TiN-coated grade delivers efficient cutting at low speeds on stainless steels (ISO P30-P50 / K25-K40), while BMK offers a sub-micron, triple-coated surface for extreme heat resistance and smooth cutting across a wide material range.
• Carbide durability and reliable performance: High-hardness carbide combined with advanced coatings provides long tool life, stable cutting action, and reduced downtime across demanding threading applications.

Use this tiny tool to achieve consistent, repeatable threads in hard-to-reach areas, streamline setups, and improve overall workflow. The combination of compact geometry, versatile coating options, and durable carbide construction helps you deliver precise results with confidence, even on challenging materials.
