The Carmex Carbide Mini Thread Mill is a compact, high-performance tool built for precise internal and external G BSP threads (55-degree) in G1/4 and G3/8 x 19. Designed for deep-hole work and high-speed milling, it delivers consistent accuracy and long tool life in a single, versatile tool.

• Carbide Grade & Coating: MT7 sub-micron carbide with a TiAlN multi-layer coating (ISO K10-K20) for exceptional wear resistance and extended tool life.
• Threading Capability: Produces both internal and external threads with a single tool, covering a wide range of pitches for versatile applications.
• Thread Form & Sizes: 55° G BSP thread form suitable for G1/4 and G3/8 x 19, aligned with common plumbing and hydraulic standards.
• Flute Design & Geometry: Spiral flutes provide smooth cutting action; 3–5 flutes reduce machining time and improve chip evacuation in deep holes.
• Coolant Through Flutes: Through-flutes coolant delivers efficient lubrication and flushing in deep-pocket threading, helping to minimize heat buildup.
• Speed, Material Range & Durability: Optimized for medium to high cutting speeds across a broad material range, including hardened metals up to 45 HRc; short profile lowers cutting forces and deflection for stable performance.
• Shank & Fit: MT7 shank design compatible with standard toolholding systems, enabling secure seating and reliable repeatability.

Benefits: This mini thread mill enables fast, accurate threading in tight or deep holes where traditional taps are prone to breakage or where multiple tools would be required. The combination of MT7 carbide with TiAlN coating, a short profile, and multi-flute geometry translates to lower cutting forces, reduced cycle times, and longer tool life across challenging materials. Ideal for manufacturing compact hydraulic fittings, pneumatic components, and precision plumbing parts, it delivers consistent thread quality while simplifying setup and tooling inventory. With its ability to handle a range of pitches and both internal and external threads, it’s a practical, reliable choice for high-precision, high-demand applications.
