Description
The Carmex Thread Mills Carbide Mini Type is a compact, high-performance threading tool engineered for UN/UNC/UNF/UNEF/UNS forms. With a 9/16" diameter and MT7 shank, it delivers precise internal and external threads in a single versatile tool.
- Thread forms and versatility: Produces UN, UNC, UNF, UNEF, and UNS threads; handles both internal and external threading with one tool, across a wide pitch range.
- Size, shank, and geometry: 9/16" major diameter, 12 TPI, MT7 shank; spiral flutes for smooth cutting and stable chip evacuation.
- Coating and material: Sub-micron MT7 carbide with a TiAlN multi-layer coating (ISO K10–K20) for exceptional wear resistance; triple coating extends tool life.
- Flute design and coolant: Spiral flutes with through-flute coolant provide efficient cooling and cooling-assisted chip removal, especially in deep holes.
- Performance and efficiency: Optimized for medium to high cutting speeds; short profile reduces cutting forces and enables shorter machining times; multi-flute design (3–5 flutes) speeds up material removal.
- Durability and material capability: Suitable for hardened materials up to 45 HRC, offering reliable threading in challenging alloys and tough workpieces.
This tool is ideal for job shops and precision manufacturers seeking to streamline threading operations. It minimizes tool changes by covering a broad range of threads with a single carbide mill, delivers steady performance at high speeds, and helps maintain accurate thread profiles even in deep-hole applications. The combination of deep-hole capability, internal/external threading with one tool, and extended tool life through advanced coating makes it a practical, durable choice for demanding machining environments.
