At Wangdefu, our Carbide Thread Milling Cutters are designed to solve the common challenges in internal and external thread machining. Unlike traditional taps or dies, our cutters:
Achieve high accuracy and surface finish even on difficult materials
Reduce breakage risk, ensuring lower scrap rates
Increase machining efficiency by over 30% compared to conventional methods
They are perfect for machining threads in steel, stainless steel, titanium alloys, aluminum, and high-temperature alloys. Whether it’s blind holes, through holes, left-hand or right-hand threads, our cutters deliver consistent, high-quality results.
What are the features of this product?
Ultra-Hard Carbide + Advanced Coatings
Made from ultra-fine grain carbide (HRA92+), resistant to wear and impact
Optional coatings like TiAlN, TiSiN, Naco improve hardness up to 4300HV and reduce friction to 0.25
Can withstand high temperatures up to 1000℃, suitable for tough materials
Optimized Multi-Flute Design
3–4 flute cutters ensure uniform cutting forces and vibration resistance
Supports straight flutes for strength or spiral flutes for efficient chip evacuation
Versatile & Cost-Effective
One cutter handles left/right-hand threads, internal/external threads
Compatible with CNC machines and lathes, supporting metric and imperial threads
Safer than traditional taps; broken cutters can be removed easily
High Precision & Ready-to-Use Threads
Five-axis precision grinding ensures perfect thread profiles
High cutting speed (80–200m/min) and burr-free threads
Eliminates secondary finishing, saving time and cost
Technical Specifications
| Parameter Type | Specification Range |

Recommended Cutting Parameters
| Material | Cutter Type | Cutting Speed (Vc) | Feed per Tooth (fz) |
| Carbon Steel / Cast Iron | Straight-flute | 80–120 m/min | 0.03–0.08 mm/z |
| Stainless Steel | Coated Spiral-flute | 50–80 m/min | 0.02–0.05 mm/z |
| Aluminum Alloy | Uncoated | 150–200 m/min | 0.05–0.1 mm/z |
