Carmex 16IR32UNMXC/G Threading Insert 32 Tpi 3/8 in Ic

Product Description

The CARMEX 16IR32UNMXC/G is a solid carbide laydown threading insert designed for right-hand internal UN thread cutting at 32 threads per inch (TPI). Built from micrograin solid carbide and finished with a PVD-applied TiN coating, this insert delivers consistent thread form geometry in a wide range of workpiece materials. The 60-degree included angle conforms to UN thread standard requirements. With a 3/8 inch inscribed circle (0.3750 inches) and a thickness of 0.1460 inches, it seats into standard 16IR-style toolholders used on CNC lathes and manual threading setups. Machinists and toolroom operators select this insert for precision internal threading where dimensional repeatability and tool life are critical.

This insert is suited for internal threading operations on CNC turning centers and manual lathes across a broad range of materials. The universal primary workpiece material classification covers ferrous metals, stainless steels, cast irons, non-ferrous alloys, heat-resistant superalloys, and hardened materials, corresponding to material grades H, K, M, N, P, and S. It is appropriate for both production machining environments and job-shop threading applications where a single insert grade must handle varied material requests.

Key Features

• Solid micrograin carbide substrate for high wear resistance and edge stability
• PVD TiN coating reduces friction and extends tool life across universal workpiece materials
• 60-degree included angle machined to UN thread standard
• Right-hand internal thread orientation at 32 TPI
• 3/8 inch inscribed circle fits standard 16IR-style toolholders
• Certified to CE, ISO 13485:2016, ISO 14001:2015, and ISO 45001 standards

Compatibility

Designed as an OEM-style replacement or direct-fit insert for 16IR-style internal threading toolholders used in right-hand UN internal threading applications at 32 TPI.

Installation Notes

Installation should be performed by a qualified machinist with the machine powered off and locked out before changing inserts. Use the appropriate torque wrench and insert key specified by the toolholder manufacturer when seating the insert to avoid clamping damage to the carbide. Verify insert orientation and thread hand before resuming machining operations. Inspect the insert seat and clamping surfaces for chips or debris prior to installation.
