Emuge GFR15106.5010 Thread Mill 5/16-18 Solid Carbide

Product Description

The EMUGE GFR15106.5010 is a helical flute thread mill designed for cutting internal UNC threads in a CNC machining environment. It produces 5/16-18 threads with a cutting diameter of 0.2420 inches and a length of cut of 0.6370 inches. The tool is constructed from micrograin solid carbide and features a TiCN coating for improved wear resistance and tool life. With three right-hand helical flutes and an 18 TPI configuration, it is suited for precision thread milling operations where tap breakage is a concern or where a single tool must handle multiple thread depths.

This thread mill is used in production and job-shop CNC machining on mills with helical interpolation capability. It is appropriate for ferrous and non-ferrous workpiece materials in both prototype and volume production runs. The 1/4-inch shank diameter and 1-3/8-inch shank length make it compatible with standard collet chucks and shrink-fit toolholders. Machinists and CNC programmers working in aerospace, automotive, and general manufacturing will find this tool applicable for tight-tolerance internal thread applications where thread quality and positional accuracy are critical.

Key Features

• Micrograin solid carbide construction for rigidity and wear resistance
• TiCN coating extends tool life in abrasive and harder workpiece materials
• Three right-hand helical flutes for efficient chip evacuation during thread milling
• 5/16-18 UNC internal thread profile at 18 TPI
• Helical interpolation design allows a single tool to produce a range of thread depths
• No coolant-through design - suitable for external flood or mist coolant delivery

Compatibility

Designed for CNC machining centers capable of helical interpolation for cutting internal UNC 5/16-18 threads. Requires a spindle toolholder accepting a 1/4-inch shank diameter.

Installation Notes

Installation and operation should be performed by a qualified CNC machinist or tooling engineer. Secure the shank in a balanced collet chuck or shrink-fit holder and verify runout before cutting. Program the tool path using helical interpolation per the thread mill manufacturer guidelines and confirm the correct climb or conventional milling direction for the workpiece material. Do not use this tool in a manual drill press or hand-held operation.
