Product Overview

The Solid Carbide UN Full-Profile Thread Mill is a premium threading solution engineered for Unified Thread Standard (UNC, UNF, UNEF) applications requiring full-profile threading with maximum precision and surface finish. Constructed from ultra-hard tungsten carbide, this tool is ideal for producing both internal and external threads, including right-hand and left-hand thread forms, across a variety of materials and thread depths.

Unlike single-point or partial-tooth cutters, the full-profile multi-tooth geometry cuts the entire thread profile in fewer passes, significantly reducing cycle times while maintaining high thread form accuracy.

Designed for CNC machines with helical interpolation capability, this thread mill offers consistent performance in mass production, precision tooling, and aerospace-grade thread fabrication.

Key Features

• Thread Standard: Supports UNC, UNF, UNEF sizes

• Geometry: Full-profile, multi-tooth design for faster cycle time

• Thread Compatibility: Internal & external / right-hand & left-hand threads

• Material: Solid tungsten carbide for superior durability

• Custom Coatings: Application-specific PVD coatings improve tool performance

Material Compatibility & Coating Recommendations

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

Advantages

• One-Pass Full Profile Cutting: Significantly reduces machining time compared to single-point cutters

• Dimensional Accuracy: Ensures consistent thread pitch and full-profile conformity

• Application Flexibility: Cuts both internal/external and LH/RH threads

• Material Versatility: Optimized for soft metals, hardened steels, titanium, and superalloys

• Repeatable Performance: Ideal for production lines or high-precision thread applications

• Extended Tool Life: Premium carbide + coating means more parts per tool

Usage Recommendation

• Use with CNC helical interpolation cycles for stable, consistent threading

• Match tool diameter to pitch to ensure full-profile thread without interference

• Apply high-pressure coolant in deep hole or difficult material applications

• Choose coatings based on material abrasiveness, thermal conductivity, and chip behavior

• For blind holes, ensure sufficient tool clearance behind cutting edge
