The Carmex Carbide Threading Insert for BSPT threading delivers precise, durable performance for machinists handling BSPT and other common thread profiles. TiAlN-coated carbide construction provides reliable cutting life and heat resistance, making it a versatile choice for busy shops.

• Five lengths (12–40 mm): Choose the right reach for your bore depth and workpiece size to optimize engagement and stability.
• Wide pitch range: Depending on length, handles pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI for broad threading needs.
• Double-sided cutting edges: Two cutting edges extend tool life and reduce downtime—except for BSPT / NPT / NPTF / American Buttress / API RD profiles where single-edge geometry is standard.
• Internal & external threading capability: For many thread profiles, the same insert can machine both internal and external threads, streamlining setup (exceptions include ISO / UN / NPSM / UNJ / Acme).
• TiAlN coating: Increases wear and heat resistance, helping maintain accuracy and finish quality over longer runs.
• Carbide construction: Rugged, precise cutting performance suitable for a range of materials and speeds.

This insert is designed to reduce tool changes and downtime while delivering consistent thread quality across BSPT and other common profiles. The combination of dual cutting edges, robust coating, and versatile length options supports efficient, accurate threading in plumbing, hydraulic, and general mechanical assemblies. Use it when you need reliable BSPT threading with the ability to tackle internal and external threads on a variety of workpieces.
