Product Overview

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.

Key Features

• 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 Compatibility & Coating Recommendations

Choosing the correct coating significantly enhances heat resistance, reduces wear, and improves cutting efficiency, especially when threading difficult materials or at high spindle speeds.

Advantages

• 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

Usage Recommendation

• 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
