Carmex 16IR0.5ISOBXC Laydown Threading Insert Carbide

Product Description

The CARMEX 16IR0.5ISOBXC is a solid carbide laydown threading insert designed for right-hand internal ISO thread cutting operations. Finished with a TiN (titanium nitride) coating, it delivers improved surface hardness and wear resistance during threading passes. The insert features a 3/8-inch inscribed circle and measures 0.146 inches thick, fitting standard laydown-style insert pockets. It is suited for CNC turning centers and manual lathes where consistent internal thread profiles are required. Machinists and tooling specialists in precision machining, job shops, and production environments are the primary installers and users of this insert.

This insert is used for generating internal ISO-standard thread profiles on ferrous and non-ferrous workpieces. The laydown geometry allows stable seating in the tool holder pocket, reducing vibration and improving thread accuracy. It is applicable in residential fixture manufacturing, industrial component production, and general precision turning applications where repeatable internal thread forms are needed. The right-hand cutting orientation makes it appropriate for the large majority of standard internal threading operations performed on CNC and manual turning equipment.

Key Features

• Solid carbide construction provides high rigidity and heat resistance during threading operations
• TiN coating increases surface hardness and extends cutting edge life
• Right-hand cutting orientation for standard internal ISO thread profiles
• 3/8-inch inscribed circle fits common laydown-style threading toolholders
• 0.146-inch insert thickness provides stable, repeatable seating in the pocket
• Laydown insert geometry minimizes deflection and chatter during internal threading passes

Compatibility

Designed as an OEM-style replacement or direct-use threading insert for laydown-style internal threading toolholders accepting a 3/8-inch inscribed circle, 0.146-inch thick insert in the 16 IR series form factor.

Installation Notes

Threading inserts are installed and changed by machinists or tooling technicians on CNC turning centers or manual lathes. Power down and de-energize the machine, engage all safety locks, and clear the work area before changing inserts. Use the manufacturer-recommended torque wrench and insert screw to secure the insert in the pocket - do not overtighten by hand. Always verify thread pitch and cutting direction against the programmed operation before resuming the cut.
