The Carmex Carbide Threading Insert – BSPT, TiAlN coated (model 40-11BSPT) is a versatile, wear‑resistant tool designed for precise BSPT threading on common profiles. It’s built for machinists and shops that need reliable inserts capable of handling multiple thread forms with one tool.

• Thread profiles covered: A versatile collection that supports all common thread profiles, reducing the need for multiple inserts on varied jobs.
• Length options: Five available lengths, spanning from 12 mm to 40 mm, to suit different depths, collars, and tool setups.
• Pitch range compatibility: Handles pitches from 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI, enabling a wide range of BSPT and related threads.
• Double‑sided cutting edges: Two cutting edges for extended life on most profiles; BSPT / NPT / NPTF / American Buttress / API RD variants use a single edge.
• Internal & external threading capability: For many profiles, the same insert can machine both internal and external threads, reducing tooling inventory—with exceptions for ISO / UN / NPSM / UNJ / Acme forms.
• Material & coating: Solid carbide construction with TiAlN coating for improved wear resistance and heat tolerance during demanding threading operations.

This insert is designed to streamline threading workflows: fewer tool changes, consistent thread forms across BSPT and related profiles, and dependable performance in a range of materials. The TiAlN coating helps sustain cutting performance under higher speeds and tougher materials, while the dual cutting edges maximize usable life on standard profiles. Ideal for job shops, production environments, and any shop handling BSPT threading alongside common thread forms.
