The Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - TNX Grade - 8mm Minimum Diameter x 22mm Reach (Left Hand) is a compact, left-hand threading tool built to create precise internal threads in tight spaces. With a MIL-60° partial-profile geometry and an 8 mm minimum bore capability (1.2 mm / 0.05 inch), it reaches into confined bores where larger tools can’t fit, delivering dependable threading in demanding assemblies.

Part of a versatile line of partial-profile threading bars, this tool supports 55° profiles and provides coating options for different materials and speeds. The BXC-grade is a PVD TiN-coated option optimized for low cutting speeds, offering reduced wear and smoother cuts on stainless steels (ISO P30-P50 / K25-K40). The BMK-grade uses a sub-micron base with advanced PVD triple coatings, delivering exceptional heat resistance and smooth cutting across a wider range of materials, making it a reliable general-purpose choice.

• Ultra-compact, partial-profile threading for tight bores: Designed to reach internal threads in restricted spaces with an 8 mm minimum diameter and 22 mm reach, optimized for left-hand threading in hard-to-access bores.
• BXC TiN-coated grade for low cutting speeds: PVD TiN coating reduces wear at low speeds, extending tool life and enabling smoother cuts on stainless steels (ISO P30-P50 / K25-K40).
• BMK sub-micron grade with triple PVD coating for high heat resistance: Advanced coating delivers excellent heat tolerance and consistently smooth performance across a wide material range.

Designed around Carmex’s trusted TNX-grade carbide, this tiny threading tool provides reliable, repeatable internal threads in challenging spaces. It helps streamline setups, minimize tool changes, and deliver consistent thread quality for precision components across aerospace, automotive, and general engineering applications. Buy with confidence knowing you have a durable, versatile tool purpose-built for demanding threading tasks.
