Replaceable Insert System
Cost-effective solution with replaceable carbide inserts featuring multiple cutting edges. Advanced TiAlN, AlTiN, and TiCN coatings provide enhanced hardness, reduced friction, and superior heat resistance for extended tool life.
Comprehensive Thread Standards
Complete coverage of ISO metric, UN, NPT/NPTF, BSPT, PG, and specialty thread standards with precise 55°, 60°, and 80° profiles. Single-sided and double-sided insert configurations for maximum versatility.
Precision Threading Performance
Superior thread quality with excellent surface finish, accurate pitch control, and precise thread form. Capable of machining internal and external threads in materials up to HRC65 with exceptional dimensional accuracy.
System Performance Analysis
Thread milling is a precision machining process that uses rotating multi-fluted cutters with replaceable carbide inserts to create high-quality internal and external threads. Unlike traditional tapping or threading on lathes, thread milling employs a helical interpolation path combining simultaneous X, Y, and Z axis movements for superior thread creation.
Our comprehensive system includes Thread Milling Inserts available in various configurations for specific thread standards, and Thread Milling Toolholders designed to securely hold inserts while enabling precise milling operations. Insert types range from ISO Standard and UN-60° American to specialized NPT, BSPT, and PG thread configurations.
Advanced carbide inserts feature multi-layer coatings including TiAlN, AlTiN, and TiCN that enhance surface hardness, reduce friction, and provide thermal barrier properties. This enables processing of challenging materials from standard steels to hardened alloys up to HRC65, stainless steels, titanium alloys, and superalloys.
The system offers exceptional versatility with single-point and multi-point insert designs, various toolholder configurations including single insert (SR series), twin insert, multi-insert, and specialized deep hole types (U-type, A-type). Internal coolant delivery and modular interfaces ensure optimal performance across all threading applications.
