Carmex Carbide Tiny Tool - Threading - MIR - 55° Partial - BMK Grade - 6mm Minimum Diameter x 15mm Reach

The Carmex Carbide Tiny Tool is a compact threading bar engineered for precision in tight bores. With a 6 mm minimum diameter and 15 mm reach, it tackles 55° partial-thread profiles in bores as small as 1.2 mm (0.05 in), making it ideal for miniature threading work in engineering, fabrication, and hobby machining.

Two coating grades give you flexible performance: BMK, a sub-micron carbide grade with triple PVD coating for maximum heat resistance and smooth cutting; and BXC TiN coated grade optimized for low cutting speeds and stainless steels. This tool is suitable for a wide range of materials (ISO K10-K20 for BMK; ISO P30-P50 / K25-K40 for stainless steels) and general-purpose threading, delivering consistent results across applications.

• 55° partial-profile threading geometry: Precisely forms 55-degree threads with a partial profile in tight bores, down to 1.2 mm diameter, reducing rework and ensuring accurate thread forms.
• BMK grade with triple PVD coating: Sub-micron carbide delivers exceptional heat resistance and smooth cutting for high-performance, all-material use.
• BXC TiN-coated grade for stainless steels and low-speed cutting: Low-friction performance at slower feeds, ideal for stainless steels and a wide range of materials, helping maintain edge and finish.

With its compact form factor and dual-grade coatings, this tiny threading tool enhances workflow by delivering reliable, consistent threads in hard-to-reach areas, reducing downtime and rework. The 6 mm minimum diameter and 15 mm reach enable you to complete precise threading in tight cavities, while the coatings extend tool life and maintain performance across materials. Whether prototyping small parts or producing precision components, you’ll achieve dependable results with every cut.
