The Carmex AMT Thread Mills are solid carbide tools designed for high-speed aluminum threading, delivering precise internal threads in aluminum components set to UNC/UNF/UNEF/UNS standards. Built for machinists who demand repeatable results, these mills excel where clean finishes and reliable performance matter most.

• Diameter x Thread: 3/8 in diameter with 16 threads per inch (UNC), compatible with UNC/UNF/UNEF/UNS threading standards
• Material: Solid carbide for rigidity, wear resistance, and long tool life in aluminum
• Coating: Uncoated cutting edge for precise engagement and predictable cutting behavior with aluminum alloys
• Shank: Cylindrical shank standard; Weldon shank option available on request
• Internal Coolant Bore: Built-in coolant passage for effective cooling and chip evacuation during high-speed milling
• Line: Part of the AMT family, engineered for versatility and dependable performance in aluminum threading

These features translate into tangible benefits: consistent, high-quality thread forms in aluminum with reduced built-up edge, smoother surface finishes, and efficient heat management during demanding cycles. The internal coolant and robust carbide construction help extend tool life, while the secure cylindrical (Weldon) shank option provides reliable clamping for stable, precise threading operations—even in challenging workpieces or tight tolerances.
