Carmex 16IR10UNC-5/P30 Threading Insert 10 Tpi 3/8 in Ic

Product Description

The CARMEX 16IR10UNC-5/P30 is a solid carbide laydown threading insert designed for internal UN thread cutting at 10 threads per inch. Built from uncoated solid carbide in material grade C-5 and manufacturer grade P30, this insert delivers precise 60-degree included-angle thread profiles on a wide range of workpiece materials. With a 3/8 inch (0.3750 inch) inscribed circle and a thickness of 0.146 inches, it seats reliably in standard 16IR toolholders. Right-hand cutting geometry makes it the standard choice for conventional internal threading operations on CNC lathes and turning centers.

This insert is suited for internal UN thread applications across a broad material compatibility range, including steels, stainless steels, cast irons, non-ferrous metals, and high-temperature alloys, as indicated by workpiece material codes H, K, M, N, P, and S. It is used in precision machining environments where consistent thread form and dimensional accuracy are required. Typical installers are CNC machinists and toolroom technicians working on production or job-shop turning operations.

Key Features

• Solid carbide construction in C-5/P30 grade for rigidity and wear resistance in threading applications
• Uncoated finish for consistent cutting performance across the broad H, K, M, N, P, and S workpiece material range
• 60-degree included angle produces standard UN internal thread profiles at 10 TPI
• Right-hand cutting geometry for conventional internal threading on CNC and manual lathes
• 3/8 inch inscribed circle and 0.146 inch thickness conform to standard 16IR toolholder seating
• Manufactured to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed for use in standard 16IR internal threading toolholders. Compatible with workpiece materials corresponding to ISO material groups H, K, M, N, P, and S, covering steels, stainless steels, cast irons, non-ferrous alloys, and high-temperature alloys.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machine spindle before seating or replacing inserts. Use the correct torx or clamping screw specified for the 16IR toolholder to secure the insert without over-torquing the seat. Inspect the insert pocket and clamp for chips or damage before each insert change to maintain thread form accuracy.
