The Carmex AMT Solid Carbide Thread Mills are precision tools built for high-speed aluminum threading. Designed for machinists who need clean, accurate UNC/UNF/UNEf/UNS threads in aluminum, these mills deliver consistent surface finishes and reliable performance in demanding machining environments.
- Tool type: Solid carbide thread mills engineered specifically for aluminum operations
- Size and thread compatibility: 7/16 in diameter with 20 TPI; supports UN thread types including UNC, UNF, UNEF, UNS
- Shank: Cylindrical shank for straightforward mounting; Weldon shank available upon request
- Coating: Uncoated cutting edge to promote predictable engagement and controlled wear on aluminum
- Coolant and chip evacuation: Internal coolant bore provides effective cooling and efficient chip removal
- Material and build: Made from solid carbide for rigidity, heat resistance, and long tool life
When threading aluminum with this tool, you’ll achieve precise thread forms with minimal galling and clean surfaces. The internal coolant bore helps manage heat and keeps chips moving away from the cutting edge, reducing built-up edge and extending tool life. The cylindrical shank simplifies setup, and the Weldon option offers a secure, high‑rigidity hold for demanding applications. This thread mill is the ideal choice for high-speed aluminum threading tasks that demand accuracy, surface quality, and productivity.
