The Carmex AMT solid carbide thread mills are engineered for high-speed aluminum threading, delivering precise internal threads with clean surface finishes. Designed for machine shops and production environments, they combine reliability with productivity to help you get consistent, burr-free threads in aluminum parts.

• Material: Solid carbide cutting edges deliver rigidity, wear resistance, and long tool life when machining aluminum.
• Shank configuration: Cylindrical shank for versatile toolholding; Weldon shank available on request for secure retention and quick changes.
• Coating: Uncoated cutting edge provides a predictable, sharp cut and stable performance during high-speed aluminum threading.
• Coolant and chip evacuation: Internal coolant bore channels coolant directly to the cutting zone and aids in efficient chip removal, reducing heat buildup.
• Thread compatibility: Optimized for UN thread forms (UNC, UNF, UNEF, UNS) to produce accurate, repeatable threads in aluminum parts.
• Sizes: Designed to cover common aluminum threading sizes, including 3/8 in and 9/16 in variants with 5/8 x 24 threading where applicable.

These mills help you achieve tight tolerances and smooth thread surfaces at higher feeds and speeds, minimizing built-up edge and improving heat management. The internal coolant bore and uncoated edge work together to enhance chip evacuation and surface quality, while the carbide construction ensures consistent performance across multiple tool paths. Ideal for aerospace, automotive, and precision aluminum components, this toolset supports reliable production runs and reduced rework by delivering repeatable, high-quality threaded features.
