Carmex 30I10UNMT7 Carbide Thread Mill Insert 10 Tpi

Product Description

The CARMEX 30I10UNMT7 is a carbide thread mill insert engineered for internal threading operations on UN-standard threads at 10 teeth per inch (TPI). Manufactured from submicron carbide in the MT7 grade, this insert carries a TiAlN finish that improves wear resistance and heat tolerance during high-speed milling cycles. The insert style is 30I with a thickness of 0.2170 inches, making it a precision component for machinists and tool-and-die professionals working on thread milling applications where dimensional accuracy is critical.

This insert is intended for internal UN thread profiles conforming to ANSI B1.1-1989 and is suited for use in CNC machining centers where thread milling is preferred over tapping. Typical applications include threading blind holes, hard materials, and situations requiring a single tool to produce multiple thread sizes. It is well matched to production environments where tool life consistency and surface finish quality are primary concerns. The minimum order quantity for this insert is 5 pieces, sold in individual packaging quantities of 1.

Key Features

• Submicron carbide base material with MT7 grade designation for consistent cutting performance
• TiAlN coating provides elevated heat resistance and extended tool life in demanding materials
• Internal thread configuration at 10 TPI following ANSI B1.1-1989 UN standard
• Non-conical insert geometry suited for standard internal thread milling operations
• Thickness of 0.2170 inches for precise seating and repeatable positioning in compatible tool bodies
• Certified to multiple quality and environmental management standards including ISO 9001:2015 and ISO 14001:2015

Compatibility

Designed as an OEM-style replacement insert for thread mill tool bodies accepting the 30I insert style. Verify tool body compatibility by confirming insert style code, size code, and seat geometry before installation.

Installation Notes

Thread mill inserts should be seated and torqued into the tool body by a qualified machinist following the tool body manufacturer's clamping specifications. Ensure the spindle is fully stopped and the machine is locked out before changing inserts. Inspect the insert pocket and clamping screw for wear or debris before seating a new insert. Always confirm thread profile and TPI match the programmed toolpath before initiating a cutting cycle.
