The Carmex carbide single-point thread mill is engineered for precise internal ACME threads in small to mid‑size metal parts. With an MT11 shank and an advanced coating, it delivers reliable performance on challenging materials while maintaining tight dimensional control.

• Thread profile: Internal ACME threading capability with support for ISO M1 x 0.25 and 0-80 UNF threads.
• Size: Thread size 1/4-16 with a 16 (unit) length specification.
• Shank: MT11 for compatibility with standard milling setups.
• Flutes: Multi-flute design (3–4 flutes) for efficient chip removal and stable cutting.
• Material: Carbide construction delivers rigidity, wear resistance, and long tool life.
• Grade: MT11 Ultra-fine sub-micron cutting grade for precise thread form and surface finish.
• Coating: Triple blue PVD coating to enhance wear resistance and extend tool life in tough materials.
• Depth capability: Capable of threading up to 3.5× the thread diameter, depending on profile.

This thread mill is ideal for applications requiring clean, accurate internal threads in tight tolerances—think small fasteners, fixtures, and precision assemblies where consistent thread quality and tool longevity matter. The combination of a high-precision Ultra-fine grade, robust carbide substrate, and a durable blue PVD coating helps maintain accuracy over hundreds of cuts, while the multi-flute geometry supports effective chip evacuation and stable performance even in tougher alloys. Use cases include internal threading tasks where traditional tapping is impractical or where dedicated internal-thread milling saves cycle time and reduces part handling.
