Product Overview

The Solid Carbide UN Triple-Tooth Thread Mill is engineered for high-speed, high-efficiency thread milling in Unified Thread Standard (UN) formats. Built from premium-grade tungsten carbide, this tool features a three-flute cutting geometry that balances strength, chip evacuation, and cycle speed—making it an ideal choice for medium to large batch production of internal and external threads.

Designed for use in CNC machining centers, this thread mill can cut left-hand and right-hand threads with ease. It supports threading in a wide variety of materials—from aluminum and copper to stainless steel, tool steel, cast iron, titanium alloys, and even nickel-based superalloys—with a range of custom coatings available to match each application.

Key Features

• UN Thread Standard: Compatible with UNC, UNF, UNEF sizes

• Triple-Tooth Geometry: Offers a balance of speed, tool life, and stability

• Thread Versatility: Cuts both internal/external and left/right-hand threads

• Tungsten Carbide Core: Maintains dimensional accuracy even in tough materials

• Custom Coatings: Optimized surface treatments based on workpiece material

Material Compatibility & Coating Recommendations

Choosing the correct coating based on the material significantly improves cutting performance, chip evacuation, and tool longevity.

Advantages

• Faster Machining: Triple-tooth design allows higher feed rates

• Clean Thread Profile: Produces precise, burr-free UN threads

• Multi-Directional: Handles both RH and LH thread forms in one tool

• Universal Material Use: Switch between aluminum, stainless, or alloy steel with the correct coating

• Extended Tool Life: High hardness carbide with material-matched coatings resists wear

• Reduced Downtime: Fewer tool changes needed thanks to wide material compatibility

Usage Recommendation

• Program using G02/G03 helical interpolation for optimal thread paths

• Reduce spindle speed slightly when threading heat-resistant alloys

• For blind holes, check thread mill clearance behind the cutting edge

• Use high-pressure coolant for chip evacuation in deep threads

• Select tool length and pitch based on thread depth and standard
