Description
The Carmex AMT solid carbide thread mill with chamfer is engineered for high-speed aluminum threading, delivering precise, ready-to-use internal threads in UNC/UNF/UNEF/UNS forms. Designed for machinists who demand reliability and clean finishes, this tool combines a rugged carbide core with a chamfered threading geometry for a smooth start and consistent results.
- Tool Type: Solid carbide thread mill with chamfer geometry optimized for aluminum threading and clean thread initiation.
- Size & Thread Compatibility: 3/8" diameter, 16 TPI, supports UNC, UNF, UNEF, and UNS thread forms.
- Coating: Uncoated cutting edge for predictable wear and compatibility with aluminum machining.
- Shank: Cylindrical shank; Weldon shank option available on request for improved clamping stability.
- Coolant & Chip Evacuation: Internal coolant bore channels coolant to the cutting edge while aiding chip removal during cutting.
- Line & Application: Part of the Carmex AMT line, optimized for high-speed aluminum machining with consistent performance across long runs.
This thread mill is ideal for producing precise, burr-free threads in aluminum components such as housings, enclosures, and light-metal assemblies. The chamfered geometry helps ensure accurate thread start, while the internal coolant and chip-evacuation capability maintain a clean cut and cooler tooling conditions. With the option of a Weldon shank, you can secure the tool firmly in demanding setups, making it a dependable choice for production and prototyping alike.
