Carmex Thread Mills Solid Carbide with Chamfer are engineered for precise internal threading in aluminum, delivering clean, repeatable 1/4-20 threads across UN/UNC/UNF/UNEF/UNS standards. Designed for high-speed machining, this uncoated carbide tool combines rigidity, a smooth cutting edge, and versatile shank options to tackle demanding aluminum workpieces.

• Material: Solid carbide construction for rigidity, wear resistance, and stable performance in aluminum machining.
• Cutting Edge: Uncoated, smooth cutting edge to minimize built-up edge and improve surface finish on aluminum parts.
• Internal Coolant Bore: Integrated coolant channel for effective cooling and chip evacuation during threading.
• Shank Type: Cylindrical shank standard; Weldon shank available upon request for secure drive in heavy-duty applications.
• Thread Compatibility: Supports UN, UNC, UNF, UNEF, and UNS threads in 1/4 x 20 size for versatile aluminum threading needs.
• Brand/Series: Part of the AMT line, crafted for high-speed aluminum threading with reliable precision.
• Coating: Uncoated for predictable performance with aluminum alloys and easier reconditioning if needed.
• Application Focus: Ideal for internal threading in aluminum enclosures, housings, brackets, and other lightweight components.

These thread mills are designed to deliver consistent thread quality at high speeds, with efficient coolant and chip evacuation reducing heat buildup and extending tool life. The combination of solid carbide rigidity, a smooth uncoated cutting edge, and an internal coolant bore helps you achieve accurate thread starts, clean wall finishes, and reliable repeatability across production runs. Whether you’re updating a fixture, machining lightweight aluminum housings, or tapping into aluminum brackets, this Carmex thread mill provides a trusted, shop-ready solution.
