Carmex 14E16UNMT7 Carbide Thread Mill Insert 16 Tpi

Product Description

The CARMEX 14E16UNMT7 is a carbide thread mill insert designed for external UN thread milling at 16 teeth per inch (TPI). Built from submicron carbide in the MT7 grade, it carries a TiAlN (titanium aluminum nitride) finish that improves wear resistance and heat tolerance during high-cycle threading operations. The insert follows ANSI B1.1-1989 standards for Unified National thread form. It is sized under the 14E insert style with a thickness of 0.122 inches (3.1 mm). Machinists and CNC tool specialists install this insert into compatible thread mill bodies for precise, repeatable external thread generation on machining centers.

This insert is suited for external UN thread milling in production machining environments, including job shops and manufacturing facilities running CNC milling equipment. The 16 TPI configuration targets thread pitches common in general industrial fastening applications. The TiAlN coating makes it a practical choice for threading steel, stainless steel, and other ferrous materials where tool life and surface finish consistency are priorities. Each package contains one insert, and the minimum order quantity is 5 units.

• Certified to ISO 9001:2015, ISO 14001:2015, ISO 45001, and ISO 13485:2016

Compatibility

Designed as an OEM-style replacement insert for thread mill bodies accepting the 14E insert style with external UN thread geometry.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Power down and lock out the spindle before seating or removing inserts. Use the appropriate torx or hex key specified by the thread mill body manufacturer to secure the insert to the correct clamping torque. Inspect seating surfaces for chips or debris before installation to avoid insert rocking or premature failure.
