Carmex Carbide Tiny Tool - Threading - MIR - 60° Partial - TNX Grade - 8mm Minimum Diameter x 22mm Reach

The Carmex Carbide Tiny Tool - Threading - MIR - 60° Partial - TNX Grade - 8mm Minimum Diameter x 22mm Reach is a compact carbide threading bar designed for precise internal threads in tight spaces. Its 60° MIR geometry and compatibility with 55° profiles help you achieve accurate thread forms in small bores. With a minimum bore diameter of 1.2 mm (0.05 in), this tool enables threading in very narrow cavities, making it ideal for engineers, machinists, and hobbyists who work on compact assemblies.

Two advanced coating options extend performance across materials and speeds: the BXC TiN-coated grade is optimized for low cutting speeds on stainless steels (ISO P30-P50 / K25-K40), while the BMK sub-micron grade features a triple PVD coating for high heat resistance and smooth cutting. This versatility supports general-purpose threading across a wide material range.

• 60° MIR Partial-Profile Design: Enables precise thread formation in restricted bores and is compatible with common 55° profiles, ensuring accurate results even in tight spaces.
• Compact 8 mm Ø x 22 mm Reach: Fits into narrow bores and deep pockets, with a minimum bore capability of 1.2 mm to expand threading options on small-diameter components.
• Advanced Coatings for Versatility: Choose BXC TiN for low-speed stainless-steel threading or BMK triple-coated carbide for high heat resistance and smooth cutting across many materials, enhancing tool life and consistency.

The Carmex Tiny Tool is built to deliver dependable internal threading performance with consistent results, reducing downtime and rework. Its carbide construction and coating options are designed to maximize life in demanding environments, while the compact geometry simplifies setup and improves access in restricted work areas.
