The Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - TNX Grade - 6mm Minimum Diameter x 22mm Reach (Left Hand) is a compact carbide threading bar designed for precise internal threads in tight spaces. It’s built for engineers, machinists, and hobbyists who need reliable starts and clean, accurate threads in challenging bores.

With a 6 mm shank and 22 mm reach, this left-handed tool accesses restricted cavities while maintaining stable engagement. It can thread bores as small as 1.2 mm (0.05 in). The 60° partial-profile geometry, paired with TNX-grade carbide, delivers dependable performance across stainless steels and a broad range of materials, making it a versatile choice for everyday small-bore threading tasks.

• Coating-optimized versatility: BXC TiN-coated grade provides reliable performance at low cutting speeds and works well across a wide range of stainless steels (ISO P30–P50 / K25–K40), helping reduce wear and maintain consistent finishes.
• High-heat, smooth-cut BMK option: Sub-micron grade with advanced PVD triple coating offers exceptional heat resistance and smooth cutting for demanding materials, extending tool life and consistency.
• Compact reach with left-hand threading: 6 mm shank, 22 mm reach, and left-hand threading capability allow access to tight internal threads in restricted bores (as small as 1.2 mm), with stable engagement and reliable results.

In practice, this tool enables faster, more reliable small-bore threading in constrained spaces. The dual coating options and tough carbide deliver longer tool life, smoother cuts, and consistent results across a broad material range, making it a dependable addition to any milling, threading, or repair workflow.
