Micro 100 TM-312-24X thread mill

The Micro 100 TM-312-24X is a helical-flute thread mill manufactured from C2 micrograin carbide with an AlTiN coating. It is designed to produce UN threads in a variety of materials. The tool suits machinists and fabricators who require a dedicated thread-milling cutter for precise hole threading operations.

Helical-flute cutter for CNC threading

The helical flute geometry promotes smooth chip evacuation and reduces cutting forces during interpolation. The carbide substrate and AlTiN coating support wear resistance at elevated temperatures. The cutter requires a CNC machine capable of helical interpolation and a suitable tool holder. It eliminates the need for separate taps and allows a single tool to produce multiple thread diameters of the same pitch.

Questions about this item

How deep can the .2350 in helical-flute thread mill cut before chip evacuation becomes the limiting factor?

The 24-flute helical design continuously lifts chips out of the hole, so the practical depth limit is set by your machine rigidity and coolant reach rather than flute packing.

What spindle power and heat should I expect when running the TM-312-24X in steel all day?

C2 micrograin carbide with AlTiN coating keeps cutting temperatures low, letting a standard 1 kW spindle run the 312 thread-mill continuously without thermal overload.
