Carmex 14E18UNMT7 Carbide Thread Mill Insert 18 Tpi

Product Description

The CARMEX 14E18UNMT7 is a carbide thread mill insert designed for external thread milling operations on UN-standard threads at 18 teeth per inch. Manufactured from submicron carbide in grade MT7, this insert carries a TiAlN finish that improves wear resistance and extends tool life in demanding milling applications. The insert style is 14E with a thickness of 0.1220 inches. It is intended for use by machinists and tooling professionals performing precision external thread milling on ferrous and non-ferrous materials where tight thread tolerances are required.

This insert is suited for thread milling applications requiring UN external thread profiles conforming to ANSI B1.1-1989. Typical installations include CNC machining centers producing external threads on shafts, fasteners, and mechanical components where a dedicated thread mill insert is preferred over tapping. The non-conical geometry and 18 TPI configuration make it well matched to standard unified thread pitch requirements across a range of workpiece materials.

Key Features

• Submicron carbide substrate in manufacturer grade MT7 for consistent cutting performance
• TiAlN coating provides enhanced heat and wear resistance during thread milling
• External UN thread profile conforming to ANSI B1.1-1989
• 18 teeth per inch for standard unified thread pitch applications
• Insert style 14E with 0.1220-inch thickness for precise seat fit
• Non-conical geometry for straightforward thread form production

Compatibility

Designed as an OEM-style replacement or direct-fit insert for thread mill bodies accepting style 14E carbide inserts in external UN thread milling applications.

Installation Notes

Installation of thread mill inserts should be performed by qualified machinists familiar with CNC tooling and insert seating procedures. Ensure the tool body is clean and free of debris before seating the insert, and verify proper clamping torque per the tool body manufacturer specifications. Confirm spindle and coolant settings are appropriate for carbide tooling before initiating the threading cycle. Handle TiAlN-coated inserts carefully to avoid chipping the cutting edge prior to use.
