Solid Carbide Cutter for Left/Right-Hand Threads
Our Solid Carbide UN Single-Point Thread Mill is designed for high-accuracy threading operations across a wide range of materials and applications. Manufactured from ultra-fine grain tungsten carbide, this tool enables precise and versatile machining of Unified National (UN) threads, supporting both internal and external, as well as right-hand and left-hand threads.
With its single-tooth geometry, this thread mill delivers exceptional control over thread pitch and depth, making it ideal for CNC helical interpolation. It is especially suited for industries that demand thread consistency in aerospace, automotive, medical, and mold manufacturing.
To further improve performance and longevity, a range of specialized coatings is available depending on the workpiece material—boosting tool life and machining efficiency.
Thread Standard: UN (Unified National, UNC/UNF/UNEF)
Geometry: Single-point tooth for ultra-precise thread form
Thread Types: Internal & external / right-hand & left-hand threads
Material: Solid tungsten carbide for superior hardness and wear resistance
Coating Options: Tailored coatings for different materials (TiAlN, AlCrN, DLC, etc.)
Material Type | Recommended Coating |
---|---|
45# Medium Carbon Steel | TiAlN or AlCrN |
Stainless Steel (304/316) | AlCrN or TiSiN |
P20 Tool Steel | TiAlN |
Cast Iron | TiCN or uncoated |
Titanium Alloys | TiSiN or DLC |
High-Temperature Alloys (Inconel, Hastelloy) | AlCrN or nano-composite coatings |
Choosing the correct coating significantly enhances heat resistance, reduces wear, and improves cutting efficiency, especially when threading difficult materials or at high spindle speeds.
Universal Threading: One tool handles all thread directions and locations
Exceptional Precision: Single-tooth control for tight tolerance threads
Optimized Coatings: Match the tool to the material for maximum performance
Wide Material Range: From mild steel to titanium and heat-resistant alloys
Minimal Vibration: Improved stability during deep or fine thread cutting
Cost Efficiency: Reduced tool inventory with multipurpose capability
Use helical interpolation (G02/G03) for accurate thread milling paths
Choose appropriate RPM/feed based on coating, material, and thread pitch
Apply high-pressure coolant or MQL for stainless/titanium alloys
Ensure tool overrun clearance in blind hole applications
For high-volume production, consider a dedicated tool path simulation to avoid tool overload
