- Thread profiles covered: A versatile collection of threading inserts that cover all common thread profiles.
- Length options: Available in five lengths (12 mm to 40 mm); depending on the length, it can handle pitches from 0.5 mm / 32 TPI to 6.0 mm / 4 TPI.
- Double-sided cutting edges: Each insert has two cutting edges to maximize usable life and reduce changeovers (except BSPT / NPT / NPTF / American Buttress / API RD).
- Internal/external threading flexibility: For many thread profiles, the same insert can machine both internal and external threads (except ISO / UN / NPSM / UNJ / Acme).
- TiAlN coating: TiAlN-coated carbide construction enhances wear resistance and extends insert life in demanding threading applications.
This single, unified threading insert helps you expand capability while simplifying tooling. The dual cutting edges and varied length options support efficient machining across multiple thread forms, reducing downtime and maintaining consistent thread quality. Ideal for workshops and production environments that require dependable performance across common thread profiles with a durable, long-lasting edge.
