Micro 100 TM-080-8X Thread Mill 4-40 to 4-64 Solid Carbide

Product Description

The MICRO 100 TM-080-8X is a single profile thread mill designed for cutting both internal and external threads in the #4-40 to #4-64 thread size range, covering 40 to 64 TPI. Built from solid carbide and finished with an AlTiN coating, it delivers hard-material performance and thermal resistance in demanding machining environments. The tool features a 0.08-inch cutting diameter, a 0.125-inch shank diameter, and a 1.5-inch overall length. With 2 flutes and a 0.035-inch neck diameter, it is suited for precision thread milling on CNC machining centers where tool deflection and chip clearance must be tightly managed.

This thread mill is intended for use in machine shops and production environments where a single tool must produce a range of thread sizes without changeover. It handles both internal and external thread forms, making it a practical choice for prototype work, short-run production, and applications where threading taps are impractical due to thread tolerance requirements or difficult-to-machine materials. Machinists working with stainless steel, hardened steel, aluminum, and similar materials will find the AlTiN coating beneficial for extended tool life.

Key Features

• Cuts internal and external threads in the #4-40 to #4-64 range (40-64 TPI) with a single tool
• Solid carbide construction for rigidity and wear resistance
• AlTiN coating provides thermal protection and extended tool life in ferrous and hard materials
• 0.08-inch cutting diameter and 0.035-inch neck diameter enable access to tight thread profiles
• 2-flute geometry promotes chip evacuation in confined threading operations
• 0.5-inch neck length supports thread depth while maintaining clearance

Compatibility

Designed as a single profile thread mill for CNC machining centers capable of helical interpolation, compatible with standard 1/8-inch diameter tool holders and collets.

Installation Notes

Thread milling with this tool requires a CNC machining center programmed for helical interpolation - it is not compatible with manual or tapping-head operations. Ensure the tool holder is clean and the collet is properly torqued to the machine specification before running. Verify spindle speed and feed rate are set per the material being machined and the tool manufacturer's recommendations. Inspect the cutting edges for wear or chipping before each use, as solid carbide tools are brittle and sensitive to improper handling.
