Carmex MT0375C1111UN Thread Mill 5/8-11 Solid Carbide

Product Description

The CARMEX MT0375C1111UN is a solid carbide helical flute thread mill designed for cutting internal UNC threads to a 5/8-11 specification. It features three right-hand flutes and a TiAlN coating that supports extended tool life under high-heat cutting conditions. With a cutting diameter of 0.375 inches, a length of cut of 1.14 inches, and an overall length of 3 inches, this tool is built for precise thread milling in metalworking applications. It operates without coolant-through capability and is manufactured to Material Grade MT7, a solid carbide grade suited for threading in a range of workpiece materials.

This thread mill is intended for CNC machining centers performing internal thread milling operations on UNC 5/8-11 thread forms. It is well suited for job shops, production machining environments, and toolroom applications where thread milling is preferred over tapping - particularly in hard or abrasive materials where tap breakage is a concern. The 3/8-inch shank diameter and 1.9-inch shank length provide stable clamping in standard collet or end mill holders.

Key Features

• Cuts internal UNC 5/8-11 threads with a single helical flute tool path
• Solid carbide construction with TiAlN coating for heat and wear resistance
• Three right-hand flutes for efficient chip evacuation during thread milling
• 0.375-inch cutting diameter with 1.14-inch length of cut for thread depth control
• Material Grade MT7 solid carbide substrate for rigidity and edge retention
• No coolant-through requirement - compatible with external coolant or dry cutting setups

Compatibility

Designed for CNC machining centers using standard 3/8-inch collet or end mill holders for internal UNC thread milling operations at the 5/8-11 thread size.

Installation Notes

Thread mills of this type are installed and operated by machinists on CNC machining centers using helical interpolation cycles. Ensure the tool is securely clamped in a properly sized collet or shrink-fit holder before running any program. Verify spindle speed and feed rate parameters against the manufacturer's cutting data for the specific workpiece material before engaging the cut. Inspect the cutting edges for wear or chipping before each use, as carbide thread mills are sensitive to impact loading and improper entry conditions.
