Carmex 16ER14UNBMA Threading Insert 14 Tpi Solid Carbide

Product Description

The CARMEX 16ER14UNBMA is a solid carbide laydown threading insert designed for external UN thread form cutting at 14 threads per inch. Manufactured from submicron-grade solid carbide with a PVD-applied TiAlN coating, this insert delivers consistent thread geometry on a wide range of workpiece materials. The 60-degree included angle matches the standard UN thread profile, and the right-hand orientation suits conventional external threading operations on CNC lathes and turning centers. Licensed machinists and toolroom technicians install this insert into compatible ER-style laydown toolholders for production threading work.

This insert is suited for external threading applications across universal workpiece material categories including ferrous, non-ferrous, stainless, heat-resistant alloys, and cast materials, corresponding to material codes H, K, M, N, P, and S. It is appropriate for both high-production CNC turning environments and job-shop threading operations where repeatable thread quality is required. The 3/8-inch inscribed circle and 0.146-inch thickness conform to the 16ER insert size standard.

Key Features

• Solid submicron carbide substrate for wear resistance and edge stability
• PVD TiAlN coating provides thermal and abrasion resistance across universal workpiece materials
• 14 TPI UN thread form with 60-degree included angle for standard unified thread profiles
• Right-hand external thread orientation for conventional CNC lathe setups
• 3/8-inch inscribed circle with 0.146-inch thickness per 16ER insert standard
• Certified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed to seat in ER-style laydown threading toolholders accepting the 16ER insert size with a 3/8-inch inscribed circle. Compatible workpiece material codes include H, K, M, N, P, and S per manufacturer classification.

Installation Notes

Installation should be performed by a qualified machinist or CNC toolroom technician. Power down and lock out the machine spindle before indexing or replacing inserts. Use the correct torque wrench and clamping screw specified by the toolholder manufacturer to secure the insert - do not overtighten by hand. Verify thread pitch and form with a thread gauge after the first pass before running production quantities.
