Carmex Thread Mills Solid Carbide - For Aluminium - Metric - M3, M4 x 0.5 - UnCoated

Carmex AMT Thread Mills are solid carbide tools engineered for high-speed aluminum threading in metric sizes M3 x 0.5 and M4 x 0.5. Built for precision and reliability, they deliver clean, accurate threads with smooth finishes in demanding aluminum applications.

• Shank configuration: Cylindrical shank for versatile toolholding, with Weldon shank option available on request for secure, repeatable grip.
• Material and edge: Solid carbide with an uncoated, smooth cutting edge designed to minimize built-up edge on aluminum and provide predictable cutting performance.
• Internal coolant bore: Integrated coolant channel for effective cooling and chip evacuation, helping maintain tool life and consistent thread quality at high speeds.
• Thread compatibility: Optimized geometry for metric threads M3 x 0.5 and M4 x 0.5, enabling precise thread milling in thin-walled and blind-hole applications.
• Application focus: Specifically designed for high-speed aluminum machining, balancing aggressive material removal with excellent surface finish.

In aluminum workpieces, chip control and edge integrity are critical. The AMT thread mill's uncoated cutting edge and internal coolant collaboration minimize heat and sticking, reducing cycle times while preserving thread accuracy. The Weldon shank option enhances stability in demanding setups, making these tools ideal for aerospace, automotive, and electronics enclosures where tight tolerances and smooth thread surfaces matter. Use with compatible coolant delivery systems to maximize tool life and achieve repeatable results across multiple holes and features.
