PCD Thread Milling cutter

Engineered for secure, high-speed threading in abrasive non-ferrous materials. Our custom PCD thread milling cutters utilize CNC helical interpolation to eliminate the risk of broken taps. They deliver flawless thread profiles, superior surface finishes, and exceptionally long tool life, ensuring maximum safety for your high-value components.

Ideal Machining Operations

  • Safe Internal & External Threading Versatile threading for both blind holes and through holes without the high torque requirements of traditional tapping.

  • Machining High-Value Components The safest threading solution for expensive aerospace, automotive, or 3C parts where a broken tap would mean a scrapped workpiece.

  • Abrasive Material Threading Maintaining strict thread tolerances (e.g., 6H) in highly abrasive materials like high-silicon aluminum, CFRP, brass, and graphite.

Advantages of Sundi Thread Mills

Zero Risk of Broken Taps

Unlike traditional tapping, a thread mill is smaller than the hole diameter and produces short, manageable chips. If the tool ever breaks, it won't get stuck, completely saving your expensive workpiece from being scrapped.

Exceptional Thread Tolerance

The extreme wear resistance of the brazed PCD cutting edges ensures that your first thread and your 10,000th thread share the exact same strict dimensional accuracy.

PCD Thread End Mill

Single Tool, Multiple Diameters

A single PCD thread mill can machine various hole diameters—both internal and external—as long as they share the same thread pitch, significantly reducing your tool inventory.

Excellent Chip Evacuation

Designed with optimized flutes and available with optional through-coolant designs to easily flush chips out of deep blind holes, preventing thread damage.
