Carmex Carbide Tiny Tool - Threading - MIL - 55° Partial - K20 Grade - 6mm Minimum Diameter x 15mm Reach (Left Hand) is a compact carbide threading bar designed for precision work in tight spaces. With a 6 mm minimum diameter and a 15 mm reach, this left-hand tool excels at creating 55° threads in small bores and miniature components. It supports partial-profile threading to deliver clean, repeatable results where space is limited.

Designed to thread in very small bores, the tool handles a minimum bore diameter of 1.2 mm (0.05 in). It offers two coating options to match material and speed needs: BXC is PVD TiN-coated for reliable cutting at lower speeds, especially with stainless steels (ISO P30-P50 / K25-K40); BMK is a sub-micron grade with an advanced PVD triple coating, delivering high heat resistance and a smooth cutting experience. General purpose for all materials.

• 55° Partial-Profile threading compatibility: Supports partial-profile cuts for standard 55° threads in tight spaces, enabling accurate, repeatable results in confined bores.
• Two coating options for optimized performance: Choose BXC TiN for low-speed stainless steel work or BMK’s triple-coated, heat-resistant design for demanding materials, delivering longer tool life and smoother cuts.
• Compact, left-hand design with long reach: 6 mm minimum diameter and 15 mm reach provide access to small bores, with left-hand orientation expanding threading options for versatile applications.

This combination of compact geometry, precise threading capability, and tailored coatings helps you complete intricate small-diameter threading tasks more efficiently, reduce tool changes, and achieve consistent, high-quality threads across a range of materials.
