Carmex Carbide Mini Thread Mills are compact, high-performance tools designed to create both internal and external threads in deep holes, compatible with UN family threads (UN, UNC, UNF, UNEF, UNS). Ideal for engineers and machinists who demand precise threads in tight spaces.

• Thread compatibility: Supports UN family threads (UN, UNC, UNF, UNEF, UNS) in a single tool
• Size/length: No. 2 and No. 3 diameters with 56 mm length
• Material and coating: Carbide MT7 sub-micron grade with titanium aluminum nitride multi-layer coating (ISO K10–K20)
• Cutting speed range: Optimized for medium to high cutting speeds; general purpose for all materials; excels in deep-hole work
• Flute design: Spiral flutes for a smooth cutting action; 3–5 flutes shorten machining time and improve finish
• Coolant through flutes: Through-flute coolant provides effective cooling and chip evacuation in deep holes
• Durability: Triple-coated build extends tool life and enables machining of hardened materials up to 45 HRc
• Versatility: One tool can produce a wide range of thread pitches and handles both external and internal threads

These thread mills deliver faster cycle times, reduced cutting forces from the short profile, and reliable performance on hardened workpieces. The through-coolant design minimizes heat buildup in deep cavities, while the MT7 coating resists wear for longer tool life. With the ability to cover multiple thread standards and pitches in a single tool, you’ll reduce tool changes and keep production moving.
