Emuge GFR35106.5017 Thread Mill 7/8-9 4 Flute Carbide

Product Description

The EMUGE GFR35106.5017 is a helical flute thread mill designed for cutting internal 7/8-9 UNC threads in a CNC machining environment. Built from micrograin solid carbide and coated with TiCN for extended tool life, this mill produces accurate internal threads in a single helical pass. It carries 4 right-hand flutes, a 0.6210-inch cutting diameter, and a 1.8290-inch length of cut. Coolant-through capability supports chip evacuation and thermal management during deep-thread operations. Machinists and tool-and-die professionals working in precision manufacturing, aerospace, and industrial fabrication shops will find this tool suited to demanding threading applications.

This thread mill is intended for internal thread milling of 7/8-9 UNC threads, with a minimum nominal diameter of 0.8750 inches. The 5/8-inch shank diameter pairs with standard ER or shrink-fit toolholders on CNC machining centers. The 1-29/32-inch shank length provides clearance for typical workpiece setups. With 9 teeth per inch and right-hand flute geometry, it produces clean thread profiles in steel, alloy, and other machinable materials where TiCN coating provides appropriate wear resistance.

Key Features

• Micrograin solid carbide construction for rigidity and edge retention
• TiCN coating reduces wear and extends tool life in ferrous and non-ferrous materials
• 4 right-hand helical flutes for efficient chip flow during internal thread milling
• Coolant-through design supports chip evacuation and temperature control
• Cuts 7/8-9 UNC internal threads with a 0.6210-inch cutting diameter
• 1.8290-inch length of cut accommodates deeper thread engagement requirements

Compatibility

Designed for internal thread milling of 7/8-9 UNC threads on CNC machining centers equipped with a 5/8-inch shank toolholder and coolant-through capability.

Installation Notes

Installation and operation should be performed by qualified CNC machinists following the machine tool manufacturer's toolholder torque and runout specifications. Power down the spindle and confirm zero-energy state before mounting or removing the tool. Program helical interpolation tool paths per the thread mill manufacturer's recommended feeds, speeds, and radial engagement for the workpiece material. Inspect the cutting edges for wear or chipping before each use and replace when edge condition degrades to avoid thread-profile errors.
