Carmex Carbide Threading Insert - NPTF - TiAlN Coated - 40-11.5NPTF

The Carmex Carbide Threading Insert for NPTF is a versatile, TiAlN-coated solution designed for professionals who demand precise, reliable threading across the most common profiles. This collection is built to handle a wide range of applications, making it ideal for shop environments where versatility and durability matter.

• Material: Carbide construction for high hardness, wear resistance, and long edge life in demanding threading operations.
• Length options: Five lengths from 12 mm to 40 mm to fit different component sizes and depth requirements.
• Thread pitch range: Depending on length, capable of 0.5 mm / 32 TPI up to 6.0 mm / 4 TPI, covering the most commonly encountered pitches.
• Cutting edges: Double‑sided inserts with two cutting edges (except for BSPT / NPT / NPTF / American Buttress / API RD). This means more usable life before index changes.
• Internal/External versatility: For many thread profiles, the same insert can machine both internal and external threads, reducing the need for multiple tools (exceptions: ISO / UN / NPSM / UNJ / Acme).
• Coating: TiAlN coating delivers enhanced wear resistance and high‑temperature performance for tougher materials and tougher cutting conditions.
• Coverage: A comprehensive collection that spans the most common thread profiles, designed to streamline setup and tool management.

This insert set is engineered to simplify threading workflows: choose the appropriate length for the job, leverage the dual cutting edges to maximize tool life, and rely on the TiAlN coating to maintain performance under heat and wear. The result is consistent thread quality, fewer tool changes, and a smoother path from roughing to finishing in metalworking projects.
