UNC Thread Milling Cutter
UNC Thread Milling Cutter is a high-precision solid carbide CNC tool designed for standard UNC (Unified National Coarse) 60° inch threads. Optimized for American-standard industrial components, it replaces traditional fragile UNC taps to deliver stable, burr-free, high-precision internal and external threads. Suitable for deep holes, blind holes and hardened materials, it effectively avoids tap breakage and thread damage, greatly boosting production efficiency and finished product quality for inch thread machining.
Key Features
- Standard UNC Precision: Precisely CNC ground to comply with US unified coarse thread standards, ensuring accurate pitch, complete thread profile and perfect assembly interchangeability.
- Durable Solid Carbide Build: Adopts ultra-fine grain carbide substrate with high hardness and rigidity, stably machining carbon steel, stainless steel, alloy steel and hardened steel up to HRC 55 without deformation.
- High-Performance Coating: Equipped with TiAlN/AlTiN nano coating, resisting high temperature up to 900°C. It reduces friction and material adhesion, prevents built-up edges, and extends tool service life.
- 3 Versatile Tool Types
- Single Tooth: High flexibility for small batches, prototypes and deep blind holes
- 3-Tooth: Balanced speed and durability for medium batch production
- Full Form: One-pass complete threading for high-efficiency mass production
- Stable & Clean Machining: Optimized spiral flute design enables smooth chip evacuation and low-vibration cutting, ensuring burr-free, high-precision thread surface.
- Cost-Effective & Safe: Zero tap breakage risk, low workpiece scrap rate, reusable after regrinding, effectively reducing long-term production costs.
- Wide CNC Compatibility: Fits all 3/4/5-axis CNC machines, supporting left/right-hand, internal and external UNC thread milling.
