Carmex AMT solid carbide thread mills are purpose-built for high-speed aluminum threading, delivering precise UNC/UNF/UNEF/UNS threads with clean, consistent results. Sized at 5/16" diameter with 18 TPI, this uncoated tool is ideal for shops seeking reliable, repeatable aluminum thread production.

• Thread size & standards: 5/16" diameter, 18 TPI, compatible with UNC/UNF/UNEF/UNS aluminum threads for versatile applications.
• Material & construction: Solid carbide cut ensures rigidity, wear resistance, and long tool life in aluminum machining.
• Shank type: Cylindrical shank by default; Weldon shank option available on request for secure, high-speed retention.
• Coating: Uncoated cutting edge delivers predictable performance and edge geometry maintenance in aluminum.
• Internal coolant bore: Built-in coolant channel directs fluid to the cutting edges, aiding cooling and chip evacuation.
• Edge geometry: Smooth cutting edge minimizes aluminum adhesion, supporting cleaner threads and better surface finish.
• AMT line: Part of Carmex AMT tooling family, designed to meet the demands of fast, accurate aluminum threading.

This thread mill addresses the unique challenges of aluminum parts—from minimizing built-up edge and galling to maintaining tight tolerances at high speeds. The internal coolant bore, combined with a robust carbide body and a secure shank configuration, helps reduce cycle times while extending tool life. Use it for aluminum housings, enclosures, brackets, and other components requiring reliable UNC/UNF/UNEFE/UNS threads, with predictable wear and repeatable results across production runs.
