Carmex 16IR10ABUTMXC Threading Insert 10 Tpi Solid Carbide

Product Description

The CARMEX 16IR10ABUTMXC is a solid carbide laydown threading insert designed for internal American Buttress thread forms. It features a TiN (titanium nitride) finish, operates at 10 threads per inch (TPI), and carries a 3/8 inch inscribed circle with a thickness of 0.146 inches. This is a right-hand insert intended for use in indexable threading toolholders on CNC lathes and manual turning centers. Machinists and toolroom operators install this insert when producing internal Buttress threads, which are common in high-load, unidirectional applications such as hydraulic cylinders, jacks, and breech mechanisms.

This insert is suited for internal threading operations on both ferrous and compatible non-ferrous workpieces where the American Buttress thread profile is required. The laydown seating style provides a stable, repeatable cutting edge orientation in compatible 16 IR series toolholders. Typical applications include production threading on CNC turning equipment in industrial and job-shop environments. This insert is sold individually with a minimum order quantity of 10 units per purchase.

Key Features

• Solid carbide substrate with TiN finish for wear resistance on threading applications
• American Buttress internal thread form, right-hand cutting direction
• 10 TPI thread pitch for standard Buttress thread profiles
• 3/8 inch inscribed circle for use in 16 IR series indexable toolholders
• 0.146 inch insert thickness providing rigid laydown seating
• Laydown style insert geometry for stable, consistent edge presentation

Compatibility

Designed for use in 16 IR series laydown threading toolholders that accept the corresponding insert pocket geometry. Verify toolholder seat dimensions and insert locking style before installation.

Installation Notes

Threading inserts are installed and replaced by machinists on CNC or manual lathes. Power down and lock out the spindle before changing inserts. Use the correct torx or hex key to seat the insert clamp to the toolholder manufacturer's specified method without over-torquing. Inspect the insert pocket for chips or debris before seating a new insert to ensure proper clamping and edge repeatability.
