Carmex 30E18UNMT7 Carbide Thread Mill Insert 18 Tpi Un

Product Description

The CARMEX 30E18UNMT7 is a carbide thread mill insert designed for external UN thread milling applications. It carries an MT7 manufacturer grade with a TiAlN finish, providing wear resistance in demanding cutting environments. The insert is manufactured from submicron carbide and runs at 18 teeth per inch, producing clean, accurate UN thread profiles. At 0.2170 inches thick, the geometry is suited for precision thread milling in materials where tool life and surface finish matter. Licensed machinists and CNC operators install this insert as part of a thread mill tooling system in production and job-shop settings.

This insert is intended for external UN thread milling operations and conforms to ANSI B1.1-1989 thread standards. The 30E insert style with a size code of 30 fits compatible thread mill bodies designed for that insert family. Typical applications include threading operations on CNC machining centers where a single-point or multi-tooth thread mill is used in place of a tap, allowing greater process control on through holes, blind holes, and precision-tolerance fastener threads.

Key Features

• Submicron carbide substrate for extended cutting life
• TiAlN coating for heat and wear resistance in high-speed milling
• 18 TPI external UN thread profile per ANSI B1.1-1989
• Non-conical geometry for consistent thread form
• Insert style 30E with size code 30 for system compatibility
• Certified to ISO 9001:2015, ISO 14001:2015, ISO 45001, and ISO 13485:2016

Compatibility

Designed for use in thread mill tooling bodies that accept the 30E insert style with size code 30. Confirm insert pocket dimensions and clamping system requirements against the specific tool body before installation.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Ensure the machine spindle is fully stopped and the tool is secured in a vise or holder before seating or removing the insert. Use the correct torque wrench and clamping screw specified by the tool body manufacturer - do not overtighten, as this can crack carbide. Verify insert seating and runout before beginning the thread milling cycle.
