Emuge GFR15106.5012 Thread Mill 7/16-14 Unc Solid Carbide

Product Description

The EMUGE GFR15106.5012 is a helical flute thread mill designed for cutting internal UNC threads in metalworking and precision machining applications. Built from micrograin solid carbide and coated with TiCN for wear resistance and extended tool life, this mill produces 7/16-14 threads in a single helical pass. It runs three right-hand flutes with a cutting diameter of 0.3540 inches and a length of cut of 0.8910 inches. The 3/8-inch shank diameter provides rigid coupling to standard toolholders. This tool is installed by CNC machinists and toolroom operators working in production or job-shop environments.

This thread mill is suited for internal thread milling on CNC machining centers capable of helical interpolation. It targets 7/16-14 UNC thread profiles with a minimum nominal bore diameter of 0.4375 inches. Typical applications include threading hardened or abrasive materials where tap breakage is a concern and where thread milling offers process reliability advantages over conventional tapping. The TiCN coating supports use in steel, stainless steel, and cast iron at appropriate cutting parameters.

Key Features

• Micrograin solid carbide substrate for rigidity and edge retention in demanding materials
• TiCN coating reduces friction and extends tool life in ferrous and abrasive workpiece materials
• Three right-hand helical flutes for balanced cutting and efficient chip evacuation
• Cuts 7/16-14 UNC internal threads at 14 TPI with a 0.3540-inch cutting diameter
• 0.8910-inch length of cut accommodates standard thread depth requirements for this thread size
• 3/8-inch shank diameter fits common shrink-fit, collet, and milling chuck toolholders

Compatibility

Designed for use on CNC machining centers with helical interpolation capability for cutting 7/16-14 UNC internal threads with a minimum nominal diameter of 0.4375 inches.

Installation Notes

Thread mills of this type are installed by qualified CNC machinists and require a machine control capable of helical interpolation (G02/G03 with Z-axis movement). Confirm toolholder runout is within acceptable limits before use, as runout directly affects thread quality and tool life. Power down and lock out the spindle before changing or inspecting the tool. Follow the machine manufacturer and cutting tool manufacturer feed and speed recommendations for the specific workpiece material.
