The Carmex Carbide Tiny Tool is a precision threading bar designed for small-diameter bores, delivering MIL 55° partial-profile threads with a compact 6 mm minimum diameter and 15 mm reach. The left-handed geometry is ideal for tight spaces and specialized assemblies, providing reliable, repeatable thread formation where room is limited.

This tool is part of a versatile threading line offered in BMK and BXC coating grades. BMK is a sub-micron carbide grade with an advanced PVD triple coating, delivering extremely high heat resistance and smooth cutting across a wide material range. BXC is a TiN-coated option optimized for low cutting speeds, providing dependable performance on stainless steels (ISO P30–P50 / K25–K40) and general-purpose applications.

• 55° partial-profile threading: Enables accurate MIL 55° thread forms in small or restricted bores, with a 6 mm minimum diameter and 15 mm reach for access in tight spaces.
• Coated carbide for durability: BMK’s sub-micron carbide with triple PVD coating offers high heat resistance and smooth cutting; BXC TiN coating supports low-speed cutting for stable performance on stainless steels.
• Left-hand geometry for versatile applications: Designed for left-handed threading tasks, providing reliable engagement and consistent results in compact setups and awkward positions.

In practice, the Carmex Tiny Tool helps you complete intricate threading jobs faster and more consistently. Its robust carbide construction and coatings reduce wear and downtime, deliver steady thread quality across materials, and give you confidence to tackle challenging small-diameter projects with fewer reworks.
