Emuge GFR15106.5018 Helical Flute Thread Mill 1-1/8-8

Product Description

The EMUGE GFR15106.5018 is a solid carbide helical flute thread mill designed for cutting internal UNS threads sized 1-1/8-8. It features a right-hand flute direction, 4 flutes, and a TiCN coating that improves wear resistance and extends tool life in demanding materials. The cutting diameter is 0.7460 inches with a length of cut of 2.0580 inches, making it suited for threading operations that require full thread engagement at this pitch. This tool is installed and operated by machinists and CNC tooling professionals in job shop and production environments.

This thread mill is intended for internal threading applications on parts requiring a 1-1/8-8 UNS thread profile. The helical flute geometry allows the cutter to interpolate along the thread axis, producing clean internal threads in a single helical pass. The 3/4-inch shank diameter accommodates standard toolholders used on CNC machining centers. It is commonly used in aerospace, heavy equipment, and industrial manufacturing where UNS thread standards apply and solid carbide tooling is required for dimensional accuracy and surface finish.

Key Features

• Solid carbide micrograin construction for rigidity and wear resistance in hard or abrasive workpiece materials
• TiCN coating reduces friction and extends tool life compared to uncoated carbide
• 4-flute, right-hand helical design supports thread milling on CNC machining centers via circular interpolation
• Cuts internal UNS threads at 1-1/8-8 (8 TPI) with a 0.7460-inch cutting diameter
• Length of cut of 2.0580 inches accommodates deep threading requirements at this diameter
• No coolant-through design - external coolant or cutting fluid application is standard

Compatibility

Designed for use in CNC machining centers equipped with standard 3/4-inch shank toolholders; intended for internal UNS thread milling at 1-1/8-8 thread size with a minimum nominal diameter of 1.1250 inches.

Installation Notes

Installation and operation of this tool should be performed by qualified machinists or CNC tooling specialists. Secure the shank in a precision toolholder with appropriate runout tolerance before use. Program the machining center for helical interpolation to match the 8 TPI pitch; incorrect interpolation settings will produce out-of-tolerance threads. Inspect the cutting edges for wear or chipping before each use and do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material.
