Carmex 16IR10UNMXC/G Threading Insert 10 Tpi 3/8 in Ic

Product Description

The CARMEX 16IR10UNMXC/G is a solid carbide laydown threading insert designed for internal UN thread cutting at 10 threads per inch. Built from micrograin solid carbide with a PVD-applied TiN coating, this right-hand insert delivers consistent thread form and extended tool life in demanding machining environments. The 3/8-inch inscribed circle and 0.146-inch thickness conform to standard 16IR toolholder geometry. It is suited for CNC lathes and turning centers where repeatable internal threading on unified national thread forms is required. Machinists and toolroom technicians are the primary users of this insert.

This insert is intended for internal UN thread applications on CNC turning equipment. The 10 TPI thread pitch targets coarser unified thread profiles commonly found in general industrial and mechanical assembly work. The MXC grade with micrograin carbide substrate and TiN finish makes it appropriate for threading steel, stainless, and similar ferrous materials in production or job-shop environments. It fits standard 16IR-style toolholders used in internal threading boring bars. Minimum order quantity is 10 pieces; packaging quantity is 1 per pack.

Key Features

• Solid micrograin carbide substrate provides wear resistance and edge stability
• PVD TiN coating reduces friction and extends insert life on ferrous materials
• 10 TPI UN internal thread form for coarse unified national thread cutting
• Right-hand cut orientation for standard internal threading operations
• 3/8-inch inscribed circle fits 16IR toolholder geometry
• Laydown-style seating ensures consistent positioning and repeatable thread quality

Compatibility

Designed for use in 16IR-style internal threading toolholders on CNC lathes and turning centers configured for right-hand internal UN thread cutting.

Installation Notes

Installation of threading inserts is performed by machinists or toolroom technicians. Ensure the machine spindle is fully stopped and the toolholder is secured before seating or indexing the insert. Verify insert orientation and toolholder pocket cleanliness before clamping to maintain accurate thread form. Follow the toolholder manufacturer torque and clamping guidelines for the 16IR insert style.
