Experience precision threading with Carmex AMT Thread Mills—solid carbide tools designed for rapid, reliable aluminum threading. Perfect for CNC operators and shops that demand clean internal threads, smooth finishes, and efficient chip management.

• Thread compatibility: Engineered for UN threads (UNC, UNF, UNEF, UNS) to match standard aluminum fastener specifications.
• Size: 1/4" diameter with 28 threads per inch (1/4-28) for common aluminum applications and fastener insertions.
• Material: Solid carbide construction delivers rigidity, wear resistance, and long tool life in aluminum alloys.
• Coating: Uncoated cutting edge for a clean, precise engagement with aluminum materials.
• Shank configuration: Cylindrical shank for versatile mounting; Weldon shank available on request for secure clamping in demanding setups.
• Internal coolant bore: Built-in coolant channel enhances cooling and chip evacuation during high-speed threading operations.
• Series: Part of the AMT line, optimized for high-speed aluminum machining with consistent, repeatable results.

Designed to reduce chatter and improve surface finish on aluminum, this thread mill helps you achieve precise thread profiles with fewer passes. The combination of a sharp, uncoated edge and an efficient internal coolant system supports stable cutting conditions, clean chip removal, and longer tool life. The cylindrical (and Weldon-on-request) shank simplifies setup and tool changes across multiple machines, making it a dependable choice for production runs, enclosure assemblies, and prototype aluminum components alike.
