Carmex Carbide Tiny Tool – Threading – MIL – 60° Partial – BMK Grade – 4.1 mm Minimum Diameter x 17 mm Reach (Left Hand) is a compact, precision threading tool designed for partial-profile operations in tight bores. Built for MIL-grade reliability, this left-handed tool is ideal for technicians who need accurate threads in limited space, from small fixtures to delicate components.

Engineered with BMK sub-micron grade featuring advanced PVD triple coating for extremely high heat resistance and smooth cutting operation, plus the BXC TiN-coated grade for low cutting speeds and broad stainless steel compatibility, this tool line provides dependable performance across a wide range of materials (ISO P30-P50 / K25-K40). It is described as a general-purpose option for materials beyond stainless as well.

• Two-grade coating options for versatile performance: BMK offers extreme heat resistance and smooth cutting, while BXC TiN delivers reliable cutting at lower speeds on stainless steels, giving you the right tool for a range of materials.
• Partial-profile, space-conscious design: Specifically engineered for partial-profile threading, allowing precise, consistent cuts in restricted bores and complex geometries.
• Compact reach with left-hand threading: 4.1 mm minimum bore compatibility and 17 mm reach, paired with left-hand orientation to expand use in tight assemblies and common left-handed thread applications.

With its compact reach and durable coatings, this tool helps you complete small-bore threading tasks with confidence, delivering consistent threads and reducing rework. The BMK and BXC coatings minimize heat buildup and wear, supporting longer tool life and steady performance across stainless steels and other materials.
