Carmex 30E8UNMT7 Carbide Thread Mill Insert 8 Tpi

Product Description

The CARMEX 30E8UNMT7 is a carbide thread mill insert designed for external UN thread milling applications at 8 teeth per inch (TPI). Built from submicron carbide with a TiAlN finish, this insert provides wear resistance and thermal stability during thread milling operations on a range of materials. It carries manufacturer grade MT7 and conforms to ANSI B1.1-1989 thread standards. The insert style is 30E with an insert size code of 30, and it measures 0.217 inches in thickness. Machinists and toolroom operators use this insert in CNC thread milling setups where consistent thread form and tool life are priorities.

This insert is suited for external UN thread milling in production and job-shop environments. The 8 TPI configuration fits common fastener thread profiles found in general manufacturing, aerospace, and industrial fabrication work. The TiAlN coating helps maintain cutting edge integrity at elevated cutting temperatures, making it a practical choice for ferrous and hardened material applications. Minimum order quantity is 5 units; each package contains 1 insert.

Compatibility

Designed for use in compatible CARMEX 30E-series thread milling toolholders configured for external UN threading applications at 8 TPI.

Installation Notes

Thread mill insert installation and indexing should be performed by a qualified machinist with the machine powered off and spindle locked. Use the appropriate torque wrench and insert screw to seat the insert fully against the pocket without over-torquing, which can crack the carbide. Verify insert orientation and thread direction before resuming cutting operations. Follow the toolholder manufacturer's clamping specifications for the 30E insert style.
