Carmex 16ER14NPTFBXC Threading Insert 14 Tpi Nptf Carbide

Product Description

The CARMEX 16ER14NPTFBXC is a solid carbide laydown threading insert engineered for right hand external NPTF thread cutting at 14 threads per inch. Built to the 16 ER insert style, it carries a TiN coating applied via PVD process, which improves surface hardness and extends tool life during threading operations. The inscribed circle measures 0.375 inches and the insert thickness is 0.146 inches. This insert is used by machinists and CNC lathe operators producing pipe-thread connections that must meet NPTF dry-seal standards without additional sealant.

This threading insert is suited for producing external NPTF pipe threads on lathes and turning centers in job shop, production machining, and maintenance environments. The 14 TPI pitch corresponds to common pipe thread sizes in plumbing, hydraulic, and pneumatic fitting applications. The BXC manufacturer grade designation indicates the specific carbide substrate and coating combination selected for steel and general-purpose threading. Sold individually with a minimum order quantity of 10 pieces.

Key Features

• Solid carbide substrate for rigidity and wear resistance in threading operations
• TiN coating via PVD process for improved hardness and reduced built-up edge
• 14 TPI pitch for NPTF dry-seal external pipe thread forms
• Right hand cutting orientation for standard lathe threading passes
• 0.375 inches inscribed circle in 16 ER laydown insert style for compatible toolholders
• BXC grade carbide optimized for general-purpose threading applications

Compatibility

Designed for use in 16 ER style threading toolholders that accept laydown inserts with a 0.375 inches inscribed circle. Suitable for cutting right hand external NPTF threads at 14 TPI on CNC and manual lathes.

Installation Notes

Installation should be performed by a qualified machinist with the lathe powered down and the spindle locked before insert seating or replacement. Confirm the toolholder pocket and clamping screw are clean and free of chips before seating the insert to ensure proper contact and repeatability. Always verify thread form and pitch with a thread gauge after the first pass. Follow the machine manufacturer guidelines and applicable shop safety standards when setting up threading operations.
