The Carmex AMT Thread Mills deliver precise aluminum threading in a solid carbide tool, engineered for high-speed production and dependable surface finish. Designed for machinists who demand accuracy and reliability in UNC/UNF/UNEF/UNS thread formats, this 5/16 x 18 uncoated thread mill is built to perform.

• Thread size and compatibility: 5/16" diameter with 18 threads per inch, suitable for UNC/UNF/UNEF/UNS aluminum threads.
• Material and coating: Solid carbide with an uncoated cutting edge for sharp, consistent performance in aluminum.
• Shank type: Cylindrical shank for straightforward clamping; Weldon shank available upon request for added rigidity.
• Internal coolant bore: Integrated coolant channel provides effective cooling and chip evacuation during high-speed cuts.
• Chamfered lead-in design: Chamfer feature aids smooth thread initiation and helps minimize tool deflection for clean starts.

The AMT line is optimized for aluminum machining, combining precise edge geometry with efficient chip control to deliver superior thread quality and surface finish. Aimed at production environments, it reduces cycle times and downtime while maintaining consistent tolerances across runs. The combination of carbide hardness, uncoated edges, and internal cooling makes this thread mill a dependable choice for high-speed aluminum threading tasks, from prototypes to ongoing production.
