Emuge GFS23706.5003 Thread Mill 4-40 Solid Carbide Ticn

Product Description

The EMUGE GFS23706.5003 is a single profile thread mill designed for cutting internal threads in the 4-40 size range, covering 40 to 56 threads per inch (TPI). Built from solid carbide and finished with a TiCN coating, this tool delivers hardness and wear resistance suited to precision threading in tight-tolerance applications. With a cutting diameter of 0.081 inches and an overall length of 1.625 inches, it is sized for small-diameter internal thread work. The three-flute geometry supports efficient chip evacuation during milling cycles. Licensed machinists and CNC tooling specialists install this type of tool in multi-axis machining centers.

This thread mill is intended for internal thread milling operations in materials where solid carbide tooling is appropriate, including steels, aluminum alloys, and similar machinable metals. Its compact shank diameter of 0.125 inches and short neck length of 0.224 inches make it well-suited for small-bore applications requiring fine thread forms. The single profile design allows one tool to produce a range of pitches within the 40 to 56 TPI window, reducing the need for multiple dedicated taps in a job shop or production environment.

Key Features

• Single profile form mills internal threads from 40 to 56 TPI with one tool
• Solid carbide construction for rigidity and wear resistance in precision applications
• TiCN coating extends tool life and reduces friction at the cutting edge
• Three flutes promote chip flow during internal thread milling cycles
• 0.081-inch cutting diameter sized for small-bore, fine-thread work
• No coolant-through design - external coolant or cutting fluid application applies

Compatibility

Designed for use in CNC machining centers capable of helical interpolation, suitable for producing 4-40 internal threads across the 40 to 56 TPI range in appropriate workpiece materials.

Installation Notes

This tool is installed and operated by machinists or CNC programmers using standard collet or end mill holders compatible with a 0.125-inch shank diameter. Verify spindle runout and tool holder concentricity before threading operations, as small-diameter carbide tools are sensitive to deflection and lateral load. Program helical interpolation at the correct pitch for the target thread size. Coolant should be applied externally; this tool does not support through-spindle coolant.
