Carmex 16ER14NPTBXC Threading Insert 14 Tpi Npt Carbide

Product Description

The CARMEX 16ER14NPTBXC is a solid carbide laydown threading insert designed for external NPT thread cutting at 14 threads per inch. The insert features a 30-degree included angle and carries a TiN-type PVD coating that extends cutting edge life across a broad range of workpiece materials. With an inscribed circle of 0.375 inches and a thickness of 0.146 inches, it is sized for the 16 ER insert style and delivers consistent thread form geometry on right-hand NPT profiles. This insert is installed by machinists and CNC lathe operators running pipe-thread programs in production or job-shop environments.

The 16ER14NPTBXC is suited for external NPT threading applications on lathes and turning centers where a laydown-style insert holder accepts the 16 ER seat size. The universal primary workpiece material rating covers steel, stainless steel, cast iron, non-ferrous alloys, high-temperature alloys, and other common materials designated under the H, K, M, N, P, and S workpiece material codes. It is a practical choice for threading pipe fittings, nipples, couplings, and similar components where NPT taper thread conformance is required.

Key Features

• Solid carbide substrate for rigidity and wear resistance during interrupted or continuous threading cuts
• PVD-applied TiN coating for improved surface hardness and reduced built-up edge
• 14 TPI NPT thread form with 30-degree included angle for accurate taper thread profile
• Right-hand external cut geometry suited to standard lathe spindle rotation
• Universal material compatibility across steel, stainless, cast iron, non-ferrous, and superalloy workpieces
• Manufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in 16 ER style laydown threading insert holders configured for external right-hand NPT thread cutting. Minimum order quantity is 10 inserts; package quantity is 1.

Installation Notes

Installation is performed by a qualified machinist or CNC setup technician. The machine spindle must be stopped and the turret fully indexed before seating or removing the insert. Verify that the insert pocket and clamping screw are clean and free of chips before assembly to ensure proper insert seating and accurate thread geometry. Always confirm thread form and pitch with a calibrated NPT thread gauge after the first test pass.
