Carmex Thread Mills Carbide Mini Type - UN (UNC UNF UNEF UNS) - No. 1 x 72 - MT7

The Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading tool designed for UN-series threads (UN, UNC, UNF, UNEF, UNS). In No. 1 x 72 size, it delivers reliable internal and external thread production at speed in challenging environments.

• Thread types supported: UN, UNC, UNF, UNEF, UNS — capable of producing both internal and external threads with a single tool.
• Size: No. 1 x 72 — a compact mini type ideal for tight spaces and deep-hole work.
• Carbide grade: MT7 sub-micron carbide with TiAlN multi-layer coating (ISO K10–K20) for excellent wear resistance.
• Coating durability: Special triple coating prolongs tool life across a wide range of materials and speeds.
• Flute design: Spiral flutes with 3–5 cutting edges deliver smooth cutting action and reduce machining time.
• Coolant through flutes: Through-flute coolant enhances heat removal and chip evacuation in deep-hole applications.
• Performance in materials: Suitable for medium to high cutting speeds; capable of machining hardened materials up to 45 HRc.
• Cutting forces: Short profile design lowers cutting forces, improving stability and reducing the risk of tool breakage.
• Versatility: Enables machining a wide range of thread pitches with one tool, simplifying setups and reducing downtime.

This mini thread mill is engineered to maximize efficiency and reliability. Its combination of MT7 carbide, TiAlN coating, and through-coolant design supports fast, precise threading across materials—including hardened alloys—while maintaining long tool life. The tool’s ability to produce both internal and external UN threads and its deep-hole capabilities make it a versatile choice for precision shops, maintenance/repair work, and aerospace or automotive manufacturing where consistent thread quality and reduced cycle times matter.
