Carmex 16ER14NPTMXC/G Threading Insert 14 Tpi Npt Carbide

Product Description

The CARMEX 16ER14NPTMXC/G is a solid carbide laydown threading insert designed for cutting external NPT threads on CNC lathes and threading machines. It carries a TiN coating applied via PVD process, which improves surface hardness and wear resistance across a wide range of workpiece materials. The insert runs at 14 threads per inch with a 30-degree included angle, conforming to the NPT standard for tapered pipe threads. The inscribed circle measures 3/8 inches and the insert thickness is 0.146 inches. Right-hand cutting orientation is fixed. Manufactured to CARMEX MXC grade specifications, this insert suits production threading operations where consistent thread form and insert life are priorities.

This insert is suited for external NPT threading in both job shop and production environments. The MXC grade with TiN coating supports use across universal workpiece material categories, including ferrous alloys, stainless steels, cast irons, non-ferrous metals, plastics, and heat-resistant superalloys as indicated by material codes H, K, M, N, P, and S. Typical applications include threading pipe fittings, hydraulic components, and fluid-system connectors on CNC turning centers. The 16ER insert style is a standard laydown format compatible with common external threading toolholders in that size class. Sold individually; minimum order quantity is 10 pieces.

Compatibility

Designed as a replacement or production-run insert for external NPT threading toolholders accepting the 16ER laydown insert style. No specific toolholder model numbers were provided in the product data; verify seating dimensions and clamping method against your toolholder documentation before ordering.

Installation Notes

Insert seating and clamping should be performed by a qualified machinist following the toolholder manufacturer's torque and clamping specifications. Power down and lock out the machine spindle before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Confirm thread form and pitch with a calibrated NPT thread gauge after the first part to verify proper setup.
