Carmex Carbide Tiny Tool - Threading - MIL - 60° Partial - K20 Grade - 3.2mm Minimum Diameter x 15mm Reach (Left Hand)

The Carmex Carbide Tiny Tool is a left-hand, partial-profile threading bar designed for tight spaces and small-bore work. With a 3.2 mm minimum tool diameter and a 15 mm reach, it can thread into bores as small as 1.2 mm, making it ideal for compact machinery and precision assemblies.

It supports 55° thread profiles and is built from two advanced coating grades to fit different materials and speeds: BXC TiN coated carbide for reliable performance at low cutting speeds on stainless steels, and BMK sub-micron grade with triple PVD coatings for maximum heat resistance and smooth cutting across a broad range of materials.

• Two advanced coating grades for broad material coverage: BXC TiN provides dependable cutting at low speeds on stainless steels (ISO P30-P50 / K25-K40); BMK’s triple-coated, sub-micron grade delivers superior heat resistance and smooth cutting for general-purpose use on many materials.
• Compact partial-profile geometry for tight spaces: The 3.2 mm minimum diameter and 15 mm reach let you access small bores and short threads, while the left-hand orientation supports compatible machining setups and 55° profile threading.
• Proven durability and consistent results: Designed for long tool life with wear-resistant PVD coatings, it performs reliably across stainless steels and other materials, delivering stable, repeatable threads and reduced downtime.

With this tool, you’ll achieve precise, repeatable threads in hard-to-reach bores, supported by coating options that adapt to your material and speed. The dual-grade coatings let you tailor performance for stainless steels or broader material families, while the compact geometry and left-handed threading orientation provide versatile setup options. Built for reliability, it helps minimize downtime and improve consistency across threaded components.
